A friend of mine phoned me tonight to tell me her old HP Pavillion had begun to struggle to power up over the last few days.
A big fat zero occured when she tried to turn the pc on over the weekend - it did power up after a couple of attempts. Gradually the number of attempts have increased until tonight when any number of button pushing would kick that monkey into life.
She has checked the power cable is fitting tight and the pc has not been removed.
I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.
I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.
You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)
So 3 days ago when i turned on the pc the fan starting making a weird noise and was blowing out smoke. I took it appart after turning it off and found out it was dirty and had a dustbunny, after taking out the garbage i put it back together. The fan worked better but then my pc was running kinda slow, i realy knoticed it when running a game and a movie, was laggy and glitchy when it hadn't been before. Thinking i hadnt hooked something up correctly i took it appart again. Finding nothing wrong i put it back together again i tried to start it, the fan turns on and they caps lock and numb lock blink but nothing else happenshttp://h30434.www3.hp.com/t5/Notebook-Boot-and-Lockup/Hp-pavillion-powering-on-issues/td-p/5620660
I recently had to replace the mother board in my HP Pavillion a620n because of a nearby lightning strike. The replacement was done by a certified technician. Now when I shut the PC down I must turn off the powe strip it is connected to, turn the power stip back on and then press the power button on the top right of the PC case.
Prior to the replacement all I had to do was press the power buitton. I have checked all power settings etc and they are correct.
When I turn the power strip back on the hard drive accesss light flickers, the DVD drive light flashes and the fan start. I then pust the power button and the computer boots.
The power supply is the first piece of hardware to be hit by a power surge. it also may have been damaged
I have a Dell XPS 410 that randomly powers off and then won't power back on unless I jiggle it a bit.
I found this: http://forums.techguy.org/hardware/818967-dell-xps-410-shutdown-startup.html
Which indicates it can be the front I/O panel causing it.
How can I confirm this is the problem, and where can I get a spare?
When it isn't powering on, the mobo isn't receiving power either.
First of all hello techsupportforum com I am happy to be here and I hope you guys can help me Ever since a few weeks ago my computer does not power up on demand What that means is after I press the power button it would start the cpu and psu fans not the gpu which would stop after a few seconds After turning the power supply off by removing the power cable and turning it on again I can try to power up my up not PC powering powering off and randomly pc again After a few attempts it eventually starts BUT I'm not done yet Monitor still displays no signal I have to press the restart button until it finally works Please note everything works normally except for the random shut down until I power it off again This is not everything at random times the PC would just shut down itself and I would have to power off the psu and start it again I have replaced my PSU with no change in this behaviour My spec Psu activ w w new one Gpu gigabyte gt Cpu amd phenom ii x Mbu asrock gm-gshttp://www.techsupportforum.com/forums/f299/pc-not-powering-up-and-randomly-powering-off-910978.html
Hie,My dv6 was working perfectly fine using Windows 10 64x.The laptop started crashing every time i tried to power it on ,it was displaying that the DRIVER essential for booting was missing so i switched it off and remove the CMOS battery.When i tried to power it again,it was not displaying anything on screen.Only the wi-fi and audio lights were displaying Orange.I switched it off again and remove the RAMs and CMOS battery multiple times but with no luck.Now when i switch it on,the fan start running and the wi-fi and audio lights are always on and it quickly turns off and restart itself and the screen is still black.I powered it without RAMs ,it stays on without restarting frequentlyhttp://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Dv6-not-powering-on/td-p/5769272
My computer wont turn on. I have to take out the power cable, wait untill there isnt any electricity left then plug it back in and hope it works. Usually the fans spin for 1 second and then nothing, if i try to press the on botton again nothing at all happens. On certain occasions it actually boots and goes into windows and works fine then unexpectandly powers off. Ive got a LCD display thing that tells me what the computer is doing during startup untill windows boots. But when the fans stop spinning it just says 'Pwr_off'. Please help.
I think my first thought would be the power supply in the computer is broken. I am sure quite a few people on here would agree with that. If you are fairly tech savvy then you will probably be able to switch a known working power supply from another computer into yours to test if that is the problem. If you are not then you could see if someone you know might be able to help you with it. Or take it to a computer shop to get it fixed by a professional.
when i try to power on, only main power and fan comes on. no components. if i try and try hitting main power in back, eventually all will power up. what can be causing this?
Possibly the PSU has an intermittent fluctutation in voltage causing no post, BIOS flashes have also been know to solve cold boot problems...
If you can swap the PSU from another known working PC and if that doesnt yield a result and if you're brave enough try updating your BIOS.... bearing in mind if you **** it up you're not gonna get a post full stop
My Win Xp box with 512 Megs of DDR ram keeps powering off all by itself. I'll have it up for 40 minuites and it will just shut down and I can't power it back up until I let it sit for awhile. I tried replacing the power supply but it still happens. Ran burnintest but no errors came up. Is it the CPU. Any suggestions would help.
Seems like over-heating. Run it awhile with the case cover off and a floor fan blowing at it from the M/B side.
I haven't used my pc for about 2 weeks as I moved house. However, I just plugged all the cables etc into the back and now the pc won't power on. There's a green light at the back by the power cable input and it keeps flashing as though it's not getting a consistent power supply. Nothing happens when I press the power button on the pc. Therefore, I'm wondering if this is just a case of the power pack/psu dying, or if there's anything else I could do other than replacing it. Also, does this happen a lot when pc's aren't used for a few weeks?
Thanks a lot for any help.
Recently my laptop running XP doesn't want to power off after I click "turn off computer". No music, no nothing. Hopefully someone can tell me whats going on and how to fix it. Also, because of this I can not do a re-boot. I can press the power button on the lap top and it shuts down. Thanks for any help. Chuck

I have a simple question...I've always wondered, is it better to leave your computer on all day and turn it off only at the end of the day, or turn it on when in use and off immediately after I'm done using it?
Turn it on in the morning and off at night, or when you are finished for the day.
Sudden burst of electricity is bad for components.
Stopping and starting of spinning parts is arguably harder on them than leaving them running.
Warming up and cooling down of components should be minimized.
Many people I know leave their computers on ALL the time, only powering down for hardware changes or when the system locks up. Right now my computer has been on for 9 days 4 hours and 5 minutes.
Really there are only 4 reasons I can think of to turn it off if you have adequet cooling:
System lock up.
Of course if you are running a 9x based OS you might want to restart more often than every 9 days because 9x doesn't manage its RAM as well as the NT versions of Windows, meaning your performance will suffer after days of opening and closing programs.
I have not on powering PC my old computer I was getting ready sell by reformatting it when it just shut off I turned it back on but it only stayed on for a few minutes before it just shot off Now it won t even turn on I have tried another powersupply but that didn t work Sometimes when you flip the power switch in the back of the power supply the fans twitch a little and the is a high beep that sounds like the beep a computer will make if the power supply isn t plugged into a high in graphics card so then I thought it might be a graphics PC not powering on card and a tried another graphics card but it still didn t work It wouldn t matter if the hard-drive was fried would it PC not powering on it should still power on right So leaves the cpu and motherboard I was just wondering if you guys had any idea what the problem could be Here are the specs CPU-AMD Athlon Motherboard-ASRock K COMBO-Z RAM- GB of Rosewill pc Hard Drive- gb hatachi Vedio Card-Evga Geforce Thanks nbsp
Try another power supply first. The motherboard or a corrupt bios can cause this too
I've been trying to figure out what causes the computer to shut-down without warnings... I've tried changing the power supply, checking the board for short circuits. nothing seems to be working. then a friend of mine told me to check its RAM. I've haven't done it yet... Is it true that sometimes RAM may affect the power of the computer???
Please try Memtest (7 Passes)
But also can be the CPU overheating
Your easiest approach would be to blow out all internal dust

Well...it says that your boot drive is D:, is that correct?
Your boot drive should be C:, while the optical drive should be D:, assuming there are only those two drives in the system.
It also says that you have a bad hard drive, whether it's C: or D: and IMO that would be the first thing to check, after ensuring that all connections are correct and that the drive is properly recognized in both the BIOS and in XP Disk Management.
Do you have an MS XP CD?
I have a desktop PC that keeps dying I thought it was off powering PC keeps the power supply because when I PC keeps powering off unplugged it from the back of the computer and then plugged it back in it would start back up Eventually I changed out the power supply and it worked for about a month and then blew out again One thing though that has to be known is that this originally started happening when I was playing a game My graphics card was very hot I know but it was getting cooled enough I thought but maybe not Anyway I replaced the power supply and it did it again Then I went out and got a much better higher wattage PC keeps powering off one and that one lasted one day and I hadn t even started any games it just went out while I was on the Internet So I am wondering if maybe my motherboard is going bad or what I cleaned things up and dusted it all off and still it dies It stays on for about or minutes and then it shuts off HELP I don t want to buy new parts I don t need Any ideas My computer parts are probably years old now except my graphics card which is about years old That is an nVidia FX with mb I know everything could use an updating though I will get specific specs as soon as I can and post them but off the top of my head I have and AMD Athlon with mb RAM nbsp
Post the rest of you system specs. Is possible that the thermal seal is bad on your processor/heatsink causing it to overheat. This was the case for quite a few Pentium 4 PC’s with a high clock on the Prescott core. If you have a P4, this could be your problem.
i got this old performa 6300cd (its a macintosh) computer collecting dust. i plug it in and it sounds like the PSU is buzzing and the PRAM Battery is sertently dead. sence i dont have the keyboard (wanted to see if it turns on before buying the other components) i press the little button on the back of the mac. no boot chime, no light, no nothing
attached is what noise the PSU is making. (when it hits 2 seconds in the audio its when i unplugged the unit)
My device can not power on with the power adapter. However, it will come on with the battery. I am worried after the battery runs out, that'll be it. I got a docking station thinking it will help but it was a waste of money. Will be grateful for any clues.http://h30434.www3.hp.com/t5/Notebook-Boot-and-Lockup/Powering-On/td-p/5635795
I was using an 80mm fan in front of my laptop's fans to help cool it down. It was powered by an AT power supply. Is there any way to make it run on one of the ports. it is a gateway m505x. I could do USB, firewire(4 and 6 pin), printer port, video and svideo ports, modem jack, and microphone/headphone. I am shooting for the USB, but any of them would be fine.
Can any of these power an 80mm fan, and how do i connect it. It has only a positive and negative cable.
Hp z1 powered up with fans running super fast the now it won't power up at all. Can I repair the power box? Thanks.http://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/HP-Z1-not-powering-on/td-p/5641615
Some one please help me with this
I have a really old PC AT power supply which does not have a hard power on/off switch, It is an old supply with PS1 and PS2 connectors. I want to use this supply as a secondary supply for my system to power up some fans and extra stuff but I don't know where or how to start with. The system with which I want to use this supply is an ATX power supply system.
Whenever I connect this AT supply with 220v power cable it does not power on (The fan does not move). I have also tried connecting dummy loads like two old hard drives but it does not power on. The PSU is not faulty but it is not power on even with load. Tell me what should I do ?
All ATX power supplies need a 3volt connection to the motherboard to power on
Hello, this is my first post on the thread, hope someone can help. I have recently replaced motherboard, memory, HD & PSU on a freinds computer. As far as i can see all the connectors are in the right place, when i press the power button a red light flashes and nothing happens. The red light seems to be the indication light for the HD. It is really starting to bug me now.
Can anyone help?
thanks in advance
you may have a faulty part. the PSU could have been a dead on arrival part.
try switching it out for another one. send that one you have back.
I'd like to take a cheap unpowered USB hub, connect its upstream data leads to a computer's USB port, and its 0V and 5V leads to an independent, external power source that can handle more current than the computer's USB connection.
Would this in effect make it a powered USB hub? That is, would it make it possible to safely use a set of USB peripherals that are (in combination) too power-hungry to hook up all together to an ordinary unpowered hub?
Or would it just burn up?

i am having a problem with my pc. sometime when i power on my pc, it stays power on for a few seconds then will immediately power off then power on again by itself then work normally.
sometime it will power on but will not display anything on the screen.
at time it will power on,power off immediately and power on again then there will be no display on the screen.
does the problem come from the motherboard or memory?
Hello neo1407. Welcome to the forum.
The could be a few reasons for this behavior.
Problem with the power supply
Problem with the power switch on the computer case
Loose or unseated power connections to the motherboard.
Faulty hardware - motherboard, video card, RAM, CPU
Is this a new build?
If not, and it was running fine and this just started happening, have you made any changes to the system recently?

I Recently Took The Sides Off My Pc So I Could Get The Dust Out.
I Have Everything Back Correctly As Far As I Can Tell, But When I Turn It On It Stays On For A Couple Of Seconds Then Turns Off.
I Was Very Careful While Doing This. What Could It Be.??
You were NOT careful enough.
HOW did you clean the dust?
You should have blown out your system with one of those air-spray cans you can buy, NEVER touching ANY component directly. If you do this, that leaves only small wire connections that the air MAY blow loose.
When you power-on, do you get MORE than ONE beep from the PC speaker?
IF YOU DO, these beep are POST Beep Error Codes indicating major problem with basic hardware.
I would especially check your CPU Fan connection.

I thought of some updates installed, I restored it to earlier date, It seems ok, but here again the problem. Is there a problem on replacing my ram from 512mb to 1GB, it does affect my processor?
Somebody please help? Thanks in advance

Have you tried putting the original memory back in to test it?
It may be the new Ram, ram can be very sensitive, at times
You can also test by running Memtest on your Ram too
At this stage the first things to look at, would be
Test Safe mode works or not
Try the original Ram

have you tried to jump the power supply on to test if it is ok? first i'd check for a light on the mobo but then if you jump the green wire (usually the 14th pin on the 20pin plug) to a black one (a ground) it should turn on, if it doesn't the psu is more than likly dead and you should try another one.
Old dell desktop. Not powering up at all - no lights on, no fan sound. It did this a few weeks ago but then when left for a day powered up ok. Have changed plug fuse, used a different power cable that I know works but no good. Help!!
hi all all of a sudden the laptop does not start.Once disconnected the battery, by pressing the power button, the led starts blinking until it's pressed.I can hear a internal sound as if a safety switch is triggered. with the battery on, no way... it looks simply not charged. The charger is properly working at the desired voltage (I checked with the tester) so the trouble looks internal in the laptop power line. any idea?

Help! I am new to this board and sadly the most knowledgeable computer person in our office. Which is not saying much. I have a Dell PC I think one of the firsts pentium 4's. I has been working fine but yesterday it just wouldn't turn on. I opened it up and it was quite dusty so I cleaned it out. I plugged it into what I know to be a working outlet and with the cover off noticed a flashing light on what I believe to be the mother board. When I unplug it the light goes out so I assume the PC is getting power. Any Ideas? Thanks.
give us some specs on the pc.
Sorry its me again it seems on my last post I had RAM that wasnt supported by my motherboard even though my Is PC Powering Not Now Up! motherboard said it supported DDR RAM Anyway I sent it to Tigerdirect com Store here Now PC Is Not Powering Up! in Miami to be fixed so they did and I played my games for about two hours last night So this morning I turned on the computer and the game Now PC Is Not Powering Up! I was playing was loading up and all of a sudden my computer just shut off So I waited for it to cool down for about minutes I disconnected and reconnected the power cord I pressed the power button but it doesnt turn on now So I waited a little longer and disconnected the extension the outlet and the power cord and reconnected it But it still doesnt turn on I think it was a cooling problem but even if it was it still wouldn t turn on Please someone offer some suggestions Grizzly nbsp
you let the computer cool down? does that mean that it was hot b/c u do not want ur computer to be hot, if it is hot then either u have a crappy power supply or u dont have enough fans, how many fans do u have and what power supply do u have? (this is only if it was hot)
Okay I just finished building my pc and went to power up, pressed the button. But it will not start. Nothing happens, I hear a low whine from my power supply.

I have a Dell All in One (Inspiron One 2330) that will not power up. I tried a new cord and also tried reset (unplugged and held power key down for 30 seconds) and still nothing. I have no lights and no fans running when plugged in and attempting to power. Unit is about 3 years old .... never had to search out for repair work to be done on a computer before (either handled it myself or just bought a new unit due to age) but this is not an old unit.
First.... does anyone have any insight on steps I could do?
Second...... Is it worth to send to Dell for repair out of warranty or seek local help?
I've been a lurker here for a while and have finally come across a problem that I need some assistance with.
My Mom has an HP PC running WinXP. This computer has started powering off at random. I first assumed it was a PS problem and replaced it. Now with a brand new PS (OEM match) it is still doing the same thing. I thought it might be over heating so I removed the casing and cleaning all the air intakes and fans but still experienced the same issue. I've done everything from replacing the PS and power cables, surge protector, etc. I'm now suspecting an issue with the mobo.
I would initially try removing the side panel and directing a fan in to supply more air and see if the problem still occurs.
My laptop doesn't seem to be powering up ... I tried removing the battery and then powering it after 30 seconds ... but it doesn't seem to work .. I am completely freaking. Out ...
It looks like you are not able to Power ON the Notebook and wanting to fix the issue Please perform below shown steps to find out if this is a Software or Hardware Issue:1. Remove all Peripherals and Cables, Disconnect them and try to Power ON the Unit 2. Check for LED Light Status and ensure Power Button spring action is normal 3. Swap with a known good Power Cord and Power Adapter 4. Incase no Adapter is available, Check if the Power Adapter is slightly warmNote: This will give us a hint that the Power Adapter might be fine 5. Do you know if the Notebook was in Battery or Power Adapter Mode when you used it for the last timeNote: Ensure there is no liquid spillage or Power Outage 6. Check if the AC Adapter Port is loose/broken Note: If the Notebook doesn't Power ON even with a known good Power Adapter this confirms the Hardware fault with System Board or the DC Power Circuit Hope this helps, for any further queries reply to the post and feel free to join us again **Click the White Thumbs Up Button on left to say Thanks**Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem.

Hey all just put together a new rig a week or two ago everything s been working absolutely fine from the get-go except a few days ago it abruptly powered down I m posting now because though I was just hoping it was a one-off it s just now happened again In both instances the computer instantly loses all New randomly down? powering rig power akin to a power cut though that s obviously not the case and without any delay whatsoever quot restarts quot itself I say it in that way because it doesn t actually manage to restart it just powers everything up and loiters on a black screen doing nothing When I turn it off and back on again it boots normally As for details the first instance was New rig randomly powering down? when i d been playing Mass Effect for a couple hours which isn t any stress in this case will post specs below I should specify i d played the same game and even the same part of the game before and after that incident with no problems whatsoever and afterwards I even tabbed out frequently to check my GPU and CPU temps incase overheating was the problem In every case ME fails to stress them beyond about a c heat they idle in the high s-low s Incase overheating was the problem I did set up and run furmark for a while on stability test and it maxed out at c where it loitered with no problem Hoping it was just a one-off I tried to forget about it and moved on and everything was predictably fine for about another week I could happily play games watch HD video and do my work photoshop corel painter etc for any amount of time without issue For the past couple hours i ve been watching some standard-def MKVs about mins ago I started getting on with some work in painter without any issue for about mins was a fresh image so again nothing that would remotely stress the computer when it happened again the entire thing just lost all power booting to a blank screen until I restarted manually Incase it s relevant to a diagnosis I should point out that when I started up again my RIF file from painter which I had saved several times up until that point was completely gone without a trace The worry of it shutting down is annoying but with the added threat of losing important work this is a crushing issue and i ll really massively appreciate any help with the matter As for the system as I say I built it from scratch a couple weeks ago now and haven t had any problems with it otherwise PSU Antec Truepower w GFX Sapphire ATI Radeon CPU AMD Phenom II x MoBo ASUS Crosshair III RAM Pioneer Signature gb x gb HDD Seagate Barracuda tb SATA OS Windows Ultimate x updated All components have latest drivers I ve had minimal software etc running at the time of the incidents above basic system processes the first was purely Mass Effect and Steam and the second was Corel Painter and Foobar lightweight media player and Comodo Security in both instances I ve run virus scans and such using both Comodo and Spybot and come up clean which isn t surprising since I really haven t had chance to even get any viruses Also no logs or anything are created on the crashes so unfortunately I can t post anything like that So far overheating seems unlikely just from what I can see and i ve double-checked my connections so i m wondering if it s perhaps faulty hardware It ll be inconvenient if so but I really need to fix this before it can do any real damage Thanks for reading this rather hefty post and thanks loads in advance for any help i m desperate to fix this Happy christmas all thanks again Tz nbsp
I would check your power supply with a digital multimeter. I have a Sears Craftsman that I go for $20 at KMart (great investment).
My grandson has an old Toshiba laptop (7 years old) running XP Pro. He uses it for games and children stories. However, recently it started to power off after about 20 mins/ half hour use. The 2 fans are working and I tried it on a hard surface as well. It uses a laptop card for his wireless connection. It is ok to use after a few minutes.
Any suggestions ? I think it maybe the power supply or motherboard overheating ?
Something is overheating... see here: http://www.computerhope.com/issues/ch000780.htm
I am about to built a computer and finished installing all the hardware.As I am not 100 %
sure if all my connections are correct I intend to proceed slowly with powering up.
Therefore I disconnected the power supply from the m/b,turned the computer on,
switched the power supply on and nothing happens.
I expected that the fan of the power supply should turn.
Is this normal ?

Hello All, my 5 years old Thinkpad t420 does not power on. the power button blinks and then does nothing. After reading about the same issue on forum, i found out that system board might need replacement. Is it possible to fit any other system board in this laptop (i am looking for a cheaper option like:63Y1989 FRU instead of 04W02049 FRU which is installed in my system). or would it be better to go for a new laptop? pls advise. PS: i had bought 2 years extended warratny and got its LCD, keyboard and hinges also replaced during the same time. I have plugged in quite a bit of money in it. but i am fearful of putting anymore money in this thing. It seriously lacks the relaibility for which i had purchased it.
Before spending money in a new mobo, have you tried this good 'ol trick?
Remove the battery
Disconnect the AC adapter
Press the power button and hold it pressed for 30 seconds
Connect the AC adapter again (do not plug in the battery)
Try to boot again
You're also sure the AC adapter works fine?
Im trying to help my friend fix his aspire x1700. It suddenly stopped powering on. I went through basic troubleshooting including: replacing the power cable, trying multiple power outlets, taking the old power supply out and putting it in a different computer, (which works fine so I know its not the ps.) The weird thing is when I replaced his power supply with a different one and tried powering on the light came on and the fan started spinning for about a quarter of a second and then it shut off. But no matter what I tried I couldnt duplicate this occurence. Im just looking to see what the next step would be. Is there any way to test to see if its the mobo without replacing it, or possibly a way to test the connection between the power switch and mobo? Any help or suggestions would be appreciated.
or possibly a way to test the connection between the power switch and mobo?Click to expand...
There are two pins on the main board that comprise the power switch (which are connected also to the on/off switch). If you can determine which those are, you can try shunting them to eliminate the switch as the problem.
But, if you disconnect the wall plug from the system for about 10 minutes or so and the system fans try to spin for a split second either when the power is plugged in again or when you press the power button, the power switch is most likely okay.
Other diagnostic: Disconnect all devices and cables from the board except power, memory and video to see if the board will light up. Disconnect even the keyboard and mouse.
If it still doesn't power up, you have at least narrowed it to those remaining items. My experience is that it is most likely the board or processor.
Hi all my Desktop computer was working fine nothing wrong with it that i could see then when i went to turn it on nothing happened i just get a red light where the usual green power light is I dont think its the electric box as this has now happened with my husbands computer as well his was working fine a little slow but its an old computer but no problems then when i was turning it on for my son the same thing a red light where the green power is desktop my powering not up light usually is We thought that maybe the electric box in mine was shot but when i changed it over to my husbands computer the cpu fan worked so it couldnt have been that and also when we connected my husbands electric box to my computer the cpu fan was working So my only guess is that one of the kids has downloaded some thing that has killed the hard drives on both of them Could this be the reason Thank you for any help Richard how did the exams go Well i hope Heatherhttp://www.vistax64.com/crashes-debugging/280929-my-desktop-not-powering-up.html
Every once in a while my computer turns itself on (by itself) after being turned off. It is quite annoying especially when I leave on a trip and return to find that the computer has been turned on for the last 2 weeks!
It is alright for a few weeks, then starts doing it again for a while...so it is not regular occurence. If someone can help, it would be great...if not I might consider an exorcism.
I've got an old Seimens Nixforf Mobile 700 I keep for nostalgia reasons. Chargers gone AWOL, battery is long dead. According to the Seimens sticker,it needs 19V, 2.4a Max. The nearest charger I have in size and power is a Hewlett Packard Omnibook 6000 charger thats 19V, 3.16a. It will support the Seimens, but I'm worried about running it for any prolonged time for fear of shorting the laptop or the charger.
Is it safe or am I running a massive fire risk here? Charger is out now (and back in the HP, which I'm typing this on).
I did hear a banging noise, after which the laptop went off. However, it was the cover over the ports falling over which shocked the laptop into going off - giving it a hard tap also does this. Didn't stop me getting overly paranoid for a minute though...
the amperage rating on you're newer supply is the maximum power than can be drawn. this basically means that the supply will deliver any current up to it's rating, including your laptop's specs.
so the answer is, no, your newer hp supply won't make trouble powerwise.
The first three lights come on,when I try to start it . Nothing else happens no noise or anything. I have tried taking battery out,starting with external power only still the same.
Does it sound expensive to fix.
Can you please post a bit more about this machine?
Have you bought it as used one and now you try to fix it?
Have you maybe tried to update BIOS and now you have this problem?
On this virtual way it is not easy to offer exact diagnostic but it doesn?t sound good to me. Maybe is BIOS screwed-up. Repair can be pretty expencive.

Ave I recently purchased different parts to assemble a new computer I have an ASUS K S-MX motherboard and i got a Socket AMD Athlon for it alongwith the recommended Corsair ValueSelect GB DIMM s I got a Rosewill Case with W Power Supply for it and other peripherals like HDD etcetera The problem is the computer is not powering up The Motherboard comes with a Led when i connect the unit to a power source the Led goes on which tells me the Power Supply is ok Even the Lan Led goes on if i plug in my network cable In fact i even tried another power supply from not up! powering ASUS K8S-MX another computer and still the same results So the power supply in my case is ASUS K8S-MX not powering up! OK I have connected the Power Switch and other switches very appropriately from the Case to ASUS K8S-MX not powering up! the MOtherboard My most prominent guess is that the Power Switch on the Case is faulty I noticed the on the Motherboard there is a USB Wake-up device but to the best of my knowledge i have it disabled with Jumpers set to on both jumper switches So basically when i hit the Start Power switch on the case Nothing Happens The system stays still the Led on the Motherboard stays on but computer doesn t power up Anyone got any suggestions Thanks Mickey nbsp
Could try swapping round the connections for reset/power switch to see if the switch if faulty.
Hi guys, im having a major problem with my computer, just wondering if you guys can help? Since friday my computer has been failing to start up. When i press the power button, everything starts up for about 3 seconds, and then everything shuts down. The fans come on but nothing comes on screen. I have tried a different PSU and the problem persists. i have had the computer for around 18 months with no problems. Not too sure where to go from here, and ideas?

Welcome to Techspot
First thing that comes to mind, is to check that the cooler is properly seated on the CPU. If the cooler would be loose, the CPU overheats in seconds, and some mobos switch everything off automatically, to prevent a burnout.
Also, the CPU could have overheated already and may be dead. Check it in another PC if you can.

Nah, thats normal for alot of systems, including desktops, I wouldn't worry.
But don't know anything about your beep though.
I have a 400mhz computer where I have changed the power supply and the computer does not power on at all and the hard drive power cable was pulled when it was on. I am completely lost on this one.
If I understand correctly, you have a 400 Mhz computer and the power was unplugged while it was running. It will no longer post. You have tried to replace the power supply and it still will not post. Is that correct?
Anyone seeing this problem...

How do I fix it, it's done it before and I don't know how I fixed it but it started working again suddenly
I'd suggest you run diagnostic tool on the system. It will scan for any possible hardware issue that might be causing the system to act up
1. Power off system
2. Power on system, quickly start tapping F12 key continuously. You should be diagnostic screen. After quick tests, run full tests as well. Please report back any error code.
I wonder if any of you guys can help me. With this mobo (Pc Chips M863G) it will power on drives included perfectly with no CPU in it. However whenever I put a CPU in, duron, athlon or any other AMD it powers on for 5 secs then clicks off. There are no jumpers to change, other than a CMOS reset one.

Have you checked your computer for the Blaster Worm?
I'm putting together a new computer w/ a ASUS A7V8X-X motherboard w/ Athlon XP 2200 processor, and 430W PS. I tried starting it up and all I could hear was a high pitched sound from the power supply. I tried the power supply in another computer and it worked fine. I bought all of my parts from NewEgg. What could the problem be? I've checked all connections, and now I only have the fan hooked up, PS to the mobo, and the wiring for the power switch so that I can just test it and Please help!!!!
Try hooking the motherboard up outside the case. Something on the motherboard could be shorting out. Are you sure the sound is comming from the power supply and not some type of system board overheat alarm?

I hate feeling like such a novice My computer has had some various power issues lately A number of weeks ago the computer during regular use will simply restart It does not get quot sticky quot or frozen and on Powering inconsistently no Powering on inconsistently other irregular errors or noises occur it simply restarts This was quite frustrating but not too stressful It did not happen consistently either It would usually occur after the computer had been shut down and in the morning this is Powering on inconsistently when most of the difficulty would arise This past weekend the problem seems to have worsened Now when I attempt to power on the computer I don t get very far at all Although there definitely is some power i can open the cd tray etc That is all it seems to do It quot sounds quot like it should boot up but the led lights on the front don t light up and the light that indicates that the hard drive is quot busy quot or working to not light And the monitor doesn t recognize any action either as it stays in powersave mode Eventually after many manual restarts by myself I eventually get it to work but of course i still have the restarting problem Arrggh Any idea what this sounds like or possible things to investigate and how to Software issues i tend to be ok at fixing but this certainly is new to me Any help would be greatly appreciated nbsp
My first thought would be the power supply. Is this a custom build or is it a system from a mfg like dell, gateway, etc?

I think my battery crashed but I'm not %100 sure. Is there any way possible to turn on my PC or to figure out why it wont charge or turn on? Thanx!!
Hello MrsM and welcome to Seven Forums.
Since you didn't give any info about your computer I'm guessing you have a laptop. It's OK to run a laptop with the battery installed and using the AC adapter. Are you saying with the battery installed you can't power up the computer with AC power?
It's also OK to remove the battery and use just AC power. Will the computer start with the battery removed? If yes, it's likely you have a bad battery.

I have a hp pavilion 5000 laptop running on xp. I can't get it to power up. I've tried it power it up both with and without the battery in it using the power cord. I bought a new battery for it. This didn't work either. Is there a way to power it on, and if so would reinstalling the os help the problem?
The new battery may not have any charge at all. Check the adapter if it is giving the correct output voltage as per its label. If you do not have the tools to use to test this, use the AC adapter in a similar laptop perhaps from a friend.
Also try removing battery and AC adapter then press power ON button for 30 secs. at least. Put back the battery and plug in the AC adapter then power ON as normal.

What kind of ill-effects (if any) can happen from powering down a computer that has been locked by a user? Assuming all data has been saved before locking the computer, can significant damage or degradation occur from other users powering down a computer to "unlock" it?
Yes. If you power off the system without going through the normal shutdown procedure, you run the risk of file corruption.

Can anyone come up with any possible causes as to why a computer I'm trying to sort out keeps shutting down?
It can be sitting there minding its own business and then suddenly it will shut down... just like the power's suddenly gone - except it hasn't!
It can be running a program and often if I'm trying to do a lot of CD reading it can happen but that might just be a red herring.
I've tried it with a different graphics card and with a different CD drive but the problem persists. I've upgraded from Win98 to WinME and still the problem is there.
I *think* in tghe past I tried a differnet power supply and different memory but I can't be too sure about that. I've still those tests to do again but what can cause this machine to suddenly switch itself off?
Other than a Power Supply issue - what are the system temps like ? Any sign of overheating as the pc would (hopefully) shutdown if temps built up too much. Are the fans spinning ? And is the inside clean ? Check the vents and the heatsink for clogging.
Recently my computer has started to hang at the 'Windows is Shutting Down' screen when I tell it to turn off. There no 'It's now safe to turn off your computer', I just have to press and hold the power.

Any ideas why it should suddenly, out of the blue, decide against turning itself off?

there is a chassis intrusion terminal on the board , there was no jumper on it . so I put a jumper on , again no power up .
Not sure what else I can check , does the power button connect a positive or negative feed back to the board ! .
If any one can give me anything to test , that would be great .
The pw switch leads do not matter which way they go on. Same for the reset switch leads. The pw led and hd led leads do matter however if you get one on wrong, no problem. Just switch them around.
Next have you read the guide at the top of the page for problem builds? If not, do so. If you follow ALL steps of the guide, you will find the cause of your problem.
A very common problem with inexperienced builders is to forget the 4/8pin aux pw connector.
My computer is powering off during gaming. I have suspicions what the problem could be but I wondered if someone could take the time to analyse my diagnostic files.
(fyi: I have just removed the heatsink/fan and turned it round, and used arctic cleaning solution, preparation fluid, arctic silver 5, but its still powering off)
Many thanks in advance,
Hi nbsp I've replaced the SSD in a Thinkpad nbsp this morning and it was working fine nbsp However I had to close the E550 not up powering lid when E550 not powering up I reopened it I'd got no power at all - nothing no splash screen no LED's that I could see and no power to the fan nbsp I removed the battery and power kept my finger on the button to drain any excess power - nothing nbsp So I removed the hard drive tried again nothing removed the RAM tried again still nothing same with the fan nbsp I've stripped it right down to almost nothing but the motherboard - now when I plug in the power adapter I get the logo LED LED as it's marked on the motherboard flashing times it may have been doing that all along and not easily visible due to the lighting in the office - so there are signs of life but still absolutely nothing on the screen not even a flicker and no beep codes either nbsp One more thing I've noticed is that the smaller LED beneath LED is flashing constantly and quickly hopefully someone will know what I mean by that nbsp It's probably worth mentioning that I did a BIOS update earlier it worked after that though so may be unrelated nbsp Thanks for readinghttps://forums.lenovo.com/t5/ThinkPad-11e-Windows-E-and-Edge/E550-not-powering-up/td-p/3436533
After my computer has been on for an hour or so it completely powers off. I cant seem to find out a reason and it takes several times of attempting to start it before it will let me turn it back on. it starts to power up and then stops as windows opens
and powers back off. After i try about 10 times it will start. I have Vista installed.
Sounds like a faulty hardware issue.
How did this begin to occur? Can you associate with any hardware\software change?
Start your computer in safe mode and
Using Last Known Good Configuration to check if you can log in the system.
If it is notebook, remove battery and check.
