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.)

A: My laptop HP G61 does not power on

Perhaps you have one of those infernal HP laptop motherboard problems? How old is your HP g61, and have you kept the cooling channels free of lint and dust? How old is the hard drive?
Since it doesn't work from a battery or from wall power, you should have an experienced tech take a look.
First thing I would do is remove the hard drive, so you can rescue the data if need be.
Then I would remove the battery, and try again from the Mains. If nothing, then there is some real work ahead. Consider this a major failure in that case, and get expert help to take a look.
I doubt there is a quick fix.
Please keep us informed as to what you learn and what helped get your HP G61 back up and running.

I have a Dell 8600 about two years old. When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

Hello, I have a one-two year old Compaq Presario and it has stopped receiving power a couple of months ago. The battery currently doesn't work. I took it in to Micro Center, and they saudered the power port. That fixed the problem temporarily, but, two months later it stopped recieving power. I would really like to get some stuff off the hardrive, but to do that I would have to give power to the laptop. So my question to everyone is, is there any alternate way I can give the laptop power? One more thing, the power cord works perfectly.
 

A:Compaq laptop wont power, I need an alternate power source

Same problem here

I am having the same problem with my Presario Laptop x1015.

I sent it in for repair once, but it is happening again and I can't find my receipt so they won't honor the warentee. Bought it last Feb. Funny thing is that Compaq told me that this is
not a common problem and tried to blame me!!!!

If you know of an alternate source please reply or email [email protected]

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. and there is no cross reference.

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Again, no mention of the numbers Kensington uses on their site.

I need a cross reference for these kinds of numbers.

Kensington referred me to their telephone tech support; but, there is a language or cultural barrier that prevents their understanding what I need.

Does anyone know of such a reference?

I have had my Hp laptop for 3 years now. It has been working perfectly, up until 2 weeks ago. It would not turn on when I clicked the power button. After clicking the power button, 15 minutes later I noticed it just came to life. Sometimes it doesn't turn on at all for days, but sometimes I click the power button and it boots within 15-30 minutes. When i click the power button, nothing happens at all for that duration. No fans, no lights nothing. The only light on is the power cord button that is always on when i plug it in. I did replace the power cord, and tried cleaning out the insides, it did nothing. Should i just replace the motherboard?

Ps. Hp pavilion dv6-6c43cl

A:Hp laptop takes 15 minutes to power on after clicking the power button

See if your mobo has a power switch on the actual board itself. Power it on that way and see if the problem persists

Hello, I have a ProBook 640 G1 that will not power on. After pressing the power button, with a battery installed and the AC adapter attached, the Charging LED blinks white 9 times . Unplugging the AC adapter results in 9 amber blinks. The light on the AC Adapter itself remains solid green. With the battery removed, and attached to the AC Adapter, three lights blink continously : The light on the power button (white), the Charging LED (AMBER), and the Power LED (White). The light on the AC Adapter itself remain solid green. In both cases pressing or pressing and holding the power button has no effect. There is no indication that power is actually making in to the MB; no BIOS , nothing at all. I do not have access to another unit with the same battery or AC adapter in order to try swapping those out. Thanks,Shane

Earlier this afternoon I switched my power settings to power saver as my laptop was dieing.

I shut it down like this.

I hooked it back up to power and switched back to high performance power setting.

However, while playing games the performance is horrible. I even switched back to power saver while playing and it made no difference.

Any ideas?

Now the laptop DELL 9400 is saying I cannot defrag because the battery is too low. But I dont use the battery at all. I always use the ac adapter cord.
Is there a setting to address this issue, or is this a hardware problem?

Turn off the laptop, remove the battery and then start up again (with the AC power attached of course!). Do you still get the problem? Or does the laptop not turn on at all?

Hey, got quite a problem with my laptop.. It's a Medion Erazer X7813, worked well for ~2 years.
I was doing a graphics card benchmark yesterday and it stopped in the middle of it(monitored temperature, it was at ~80 degrees Celsius when it turned off). No bluescreen or anything just off and I couldnt restart after that(no fans nothing). I thought it might be the power supply, so I tested it, but it was doing 19v when not plugged in, but when I plugged it in and unplugged it again it was at 1v. When testing I unintentionally shorted the power supply and it showed 1v after that just as it did after plugging it in, is it shorting inside the laptop? Could it be the battery or something more serious like the MB? Any ideas are welcome!

Since i bought a new laptop E7270, is it allowed to use my power adaptor my old Dell E6420 also for the new one?   If so i can use one adaptor at home and another in office and dont need to carry the power adaptor always.
Will this impact the battery performance of the new laptop?

A:If it is possible to use the power adapter of E6420 for my new laptop E7270? Will it impact the battery of the new laptop?

If the connector fits (it may not - the older systems use a much larger barrel connector than many of the new ones), AND the power (wattage) is equal or greater, yes.

My laptop was fine a few days ago but now when I plug it into the wall ac power the laptop will not turn on at all no noise. However when I plug the power cord in I do get a light for the battery charging,(yet to see if battery will take a full charge and come on) but so far nothing. Any ideas as to fixing this or why this could happen. can I get files from laptop harddrive to my pc? Remove laptop hard drive and connect to my pc? Thanks
 

A:No Ac Power or Battery power to Laptop

Sounds like a major failure in the laptop.

You can buy adapters for laptop HDD to Desktop IDE drives, quite cheaply. That will allow you to access the files on the hard drive.

USB cases are also quite reasonable for laptop hard drives and give an easy way to access the drive.

Do you mean you need to power it on by pressing such a power button, maybe located in elsewhere on your laptop?

A:no power to laptop

If the computer will not turn on even with the AC adapter plugged in, then something more serious is going on. It could be the connector to the power plug is loose, the CPU went bad, the motherboard went bad, or a number of other things (I am not a laptop expert other than that exact thing happened to my old laptop and it never worked again).

My sister has a 1400 i series laptop. It has Win98 on it.

One night, she had the thing plugged into a surge strip and there was a storm. She thinks that the place she lives in got hit. She says the Power strip still works and other things that were plugged in power up.

I checked out the transformer and it is providing the right power and volts.

The computer just won't power up. When you press the power on button, a light flashes and that is it.

Any suggestions as to what I might have to replace? Or, what to check first?

A:Laptop won't power on

Remove the battery altogether; then hit the POWER key, which will drain any power left onboard.

Now reinstall the battery and connect to the A/C charger - - does it show as charging?

Wait a few minutes and then hit power on again - - it should resume from hibernation.

I messed around on it and it ran like normal and couldn't figure out why it wouldnt start for anyone else. I turned it off and moved it to a different room and now it won't turn on again. I think that it might be the adapter isnt drawing electricity. The light on the adapter stays dark even while its plugged in but it is old and could have just burnt out.Is there anyway to test this? Is there anything else that could be wrong?

ThanksHi, Your only option is by sending the computer for repair. Replacing the hard drive is not a guaranteed fix since this will fall under "Customer induced damage" and theres a cost for that. Accidental damage is not covered by the hardware replacement warranty. The cost will fall roughly $300-$400 plus state tax. HP Support number 1800 474 6836 Just provide with the computer's serial and product number and they will help you send the computer for repair.

Hey guys and girls, im a newbie here. In my household we have two compaq presario laptops and neither will power up "all of a sudden". One of them if you plug the power lead in the little ring lights up around it, but still nothing else happens.

With both i have tried taking the batteries out, and holding the power button to drain any excess voltage, different power supplies, and a known working battery a friend let me try and nothing happened to either.

I have had them both apart and can see no obvious faults or anything that has burnt etc.. where do i go from here?

Im not sure if it's worth mentioning, but they have both used non genuine power supplies as the originals both failed a while back....

It powered on until yesterday, I removed the hard drive (which was dead), to extract some important info, put it back in, and now nothing.
Just a note, it was making some crazy sounds prior to this whole thing, it sounded like the cpu fan was hurting, but still, shouldn't there be some sign of power now?
Thanks for nay help.

Hi and welcome. Since you were playing around inside, my suggestion would be to check connections and the ram to be sure you didn't bump something loose.

Along the lines of the cpu fan, if you fried the cpu..........

My laptop won't turn on.  I have removed the battery, plugged in with power cord and hold the button down -- no results.  The tiny light right next to the power outlet on the laptop blinks a few times but won't turn on.  This happened about a month ago and the normal reset fixed it.  The laptop is only 1.5 years old.  Any suggestions?  I upgraded to Windows 10 a few months ago.

I have a laptop that no longer powers on. It is a Dell D630. I press the button to turn it on, the power light turns on but the screen does not turn on nor do I hear any sounds of anything starting. The Power light after about 10 seconds also turns off. I am thinking it is either the power supply or the motherboard.

I have tried to take the battery out and just plug it in without the battery but that did not work either. I have tried without power plugged in and just battery and did not work.

If anyone has any input on this situation, please let me know.
 

A:Laptop will not power on!

Does your battery have sufficient power to power on the laptop?

If your battery isn't dead, you should try taking your computer to a store/shop with a known working adapter (if you don't have a spare). Once you rule out the adapter as the problem, you can pretty much assure yourself that it is hardware related (such as motherboard, DC jack..) since a working adapter will still power up a computer with no battery connected to the PC.

When i put the computer back together... It would not power on. Most of the time I can see the light turn on for 1-2 seconds and then it dies out. Sometimes i dont even get power! What the heck is going on. I need to get this computer to work. I made a promise...

Hi Guys,
I have a Latitude D600 that has died on me. I put it to bed one night and in the morning it wouldnt boot up.
When powering up absolutely nothing happens, none of the system LEDs light up, and the power supply`s green LED goes off when plugged in which I think means there is a shortage in the laptop.
I have opened it up and there is nothing obvious wrong (albeit my experience with this issue is zero).
I think i will need some test equiptment as from what i have read this is a motherboard or power regulator failure, but i really dont know what i am doing??

any advise or point at articles that i might have missed would be great.

many thanks

Hi, I have dell inspiron laptop. My laptop does not power on. When I connected charger to laptop, t he charger led goes off. I have tried to put off the battery but still there is no power in the laptop. I need help.

A:Laptop No power

There's a short in the system somewhere.  Several possibilities:
1.  The DC jack in the system is faulty.  On most newer system, that's the place to start - but we'll need to know exactly which system you have to determine whether the jack is replaceable.  That is, Inspiron N5110, 5531, etc.
2.  One of the USB ports has shorted pins (check inside the USB ports with a flashlight for pins making contact with both sides of the port.  If one or more of the ports is faulty, it may be a matter of replacing a small board -- or it may require a mainboard replacement.
3.  If neither of those is the cause, it's the mainboard that's bad.  On low-end models, or systems over 3 years old, it's really not worth replacing the board - the system should be replaced.

For some reason my laptop just did not startup with the AC adapter in it.

When me and my friend pull out the adapter and powered up the laptop it run normally.

Hi,
I have a Sony Vaio VGN-NR38E which I have been using fine for years. Today I tried to set up cloud print on my Kodak Office 2170 and installed the software on to my laptop, but when it finished it suddenly powered down like the battery had been pulled out. I have it on charge so it's not low battery and when I power it up it says "Windows failed to start, recent changes in the software or hardware may have been the cause". It then says to launch startup repair, which I do, only to have it power down a few seconds later. Any ideas?
 

A:Laptop Power Down

Does the laptop charger still work? They do fail and then the laptop drains the battery and powers off. Are there any lights on the charger? Is the charging light coming on on the laptop?

Try this;
1) Unplug the charger from the wall
2) Unplug the charger from the laptop
3) Remove the laptop battery
4) Press and hold the power button for 30 seconds
5) Re-connect the charger to the wall and see if any lights come on on the charger.
6) Connect only the charger to the laptop, see if any lights come up to indicate its plugged in or charging or if the charger's light goes off.
7) Attempt to power on the laptop and watch for any activity
8) If the laptop does nothing, disconnect the power adapter and plug in the battery. Attempt to turn it on again.
9) If nothing, reconnect the charger and let the laptop attempt to charge for a while before trying to turn it on.

Report the results of each of the testing stages.

I own a Dell Inspiron 5520 laptop and a night that I was streaming, my laptop suddenly shut off and wouldn't turn on. Nothing happens when I press the power and when I plug in the charger the light doesn't even come on, though the charging brick light does (my computer was plugged in when this happened). I have looked this up and I have tried the only suggested solution which is to remove the battery and all connections and press the power button for 30-60 seconds, then putting the battery back in and attempting to power on. I have repeated this multiple times, even doing it with only the charger connected and battery out or both charger and battery connected but nothing seems to work. I am hoping that someone can offer me a solution before I have to carry this to a technician or replace it.

Hi ADIMALIK,
What "hole near memory" are you referring to? Could you kindly post the links of forum threads, so we could review the same?
Please check if there is any damage on the machine. Check if all the ports on the machine are fine or misaligned. Sometimes if the pins in the USB ports are touching each other, they are known to cause many issues on the machine.
Are you using a Dell Adapter? Does the light on the adapter stay on and stable when connected to the system or does it go off / flash? 
Remove both the memory modules and try powering on the system and see if it comes on and beeps.
If there is no response from the machine, I would suspect the motherboard might have failed.

Hi,

The strange thing is if the battery and AC adapter or plugged in, it thinks its on battery but wont charge. If I take the battery out, it recognizes that its on AC. I have tried deleting the Battery in the Device Manager. Is this a hardware issue and can it be repaired?

A:Laptop power help

The battery is most likely bad and just needs replaced. Check Amazon or eBay for a replacement (an OEM replacement is best, try to avoid the cheaper Chinese batteries).

Edit: I re-read your post and see you said you replaced the battery already... have you checked the voltage output from your AC adapter with a multimeter to see if it's putting out the right amount?

Is it possible you also got a bad replacement battery? have you checked to make sure the battery is fully making contact with the battery terminals? Does the laptop run fine without the battery in it, and only on AC power?

When at home, or at school, is it ok to have a laptop plugged all the time? Unplug it to go to library or class but most of the time it is in the room and plugged in nonstop. Does this affect the battery and power supply/source.
 

A:laptop power

The ideal charge/discharge cycle for most laptop batteries is a full cycle, discharge/charge. OTOH, many people leave them plugged in with no ill effects, except perhaps slightly reduced battery life. I guess the real issue is, how badly do you want to maximize the life of the battery to the absolute possible degree?

A:Laptop will not power on

your cheapest place to start is with the charger, then the battery. Make sure that your charge indicator is blinking when you have the cord plugged in. It may not be charging the battery properly. Having said that, if the battery is not functioning as it should, it will not charge. No charge = no power. and also some laptops do not even power up even if the cord is plugged in if the battery is not in good condition.

Hello,

I have a HP Pavilion dv6000. It was working fine for me up till about a week ago. Now when I power it down or reboot it even, it just shuts itself completely down, and when I try to turn it back on nothing happens. No beeps, no fans turning on nothing. If I leave it, for awhile it does eventually turn itself back on. Now I have never sat there and timed it as to how long it takes as it is never the same amount of time. But have gone a whole night and part of a day. It is almost like it has a mind of its own or something LOL.

Any idea why this is? I am usually pretty computer savvy, but this has gotten me confused. The last thing I really want to hear is that it is the power supply or something lol.
 

A:Laptop Will Not Power On Right Away

It may be related to the very common failure of HP laptops with nVidia chipsets, see here: http://news.cnet.com/8301-13554_3-10020782-33.html

All of a sudden my laptop will not start, earlier it was completely fine?!?

It is a HP DV6000 series running Vista 32.

I never have the battery connected as a rule so as to preserve it, just running from the power cable.
All that happens now when i press the power button is that the indicator lights above the keyboard, (volume, play, pause etc..) light up for about a second, (as they normally would) & then just go off again. That's it!!

I've tried the 'hold the power button for a minute then plug in' but no change.

Please help, i'm lost without it!!!!!

Is there any harm to a laptop if a battery is removed and AC Power is used exclusively or is it just as productive to leave the battery installed? The laptop battery would be charged on a monthly basis.
 

A:AC Power on Laptop

no harm - only issue will be if you lose power , you will lose anything you are working on

and if you keep the battery charged each month - then you can always pop it in to use on battery - after another recharge
dont expect the battery to hold charge for a month

Dear sir,During "restart and update" which was in progress 35%. I slept off my laptop went off due to low battery. When I woke up, I plugged to power and put on the laptop. It continued from 35% but within 5seconds, the laptop went off by itself and uptil now. Not coming on.Only white light on the charging pot and when I try to power on, white light will just blink from the power switch and go again. Meanwhile the WLAN and SD ports will blink same with the power button and go off same time like 1second.Please help.

I was upgrading the CPU in a a Toshiba Satellite M115 laptop for a friend. I put it back together, and wanted to power it on...and nothing.I made sure everything was connected and still nothing. The power and battery LED come on on the PC, but nothing happens when I press the power button. It's like turning the key on a car and not even hearing it crank. Even if the CPU were bad, it would power up and give me some sort of error, but I get nothing. I tried putting the old CPU back in, and I still get nothing. Could someone please give me some sort of input?

Well... It may be your monitor going off... Check those settings... also... if you unplug your laptop.. the settings will automatically go to power save mode.. to fix this just so to the power options when it is unpluged and configure them to how you want...

I have a 3 year old AST laptop. I push the power button and nothing happens. I've tried removing and reinserting the battery. I've tried with the AC power plugged in and unplugged with no difference. Any suggestions?
 

A:Laptop - No Power up

Make sure the plug in the wall is working eg. try something else in it and see if it works.

If it is possible check the fuse in the Power supply plug.

Test the power supply with a multimeter.

Suggestions: the power supply has gone and requires replacing

Have been given a Toshiba Protege R400 Mod No:PPR40A-01000L to look at for a friend who is very ill and the machine just will not switch on.

Have tested the adaptor and battery voltage and there is plenty.

Now I don't have much experience with laptops as such and so cannot rule the PSU as the culprit.

When plugged in the blue power light is on and the small yellow battery indicator flickers at random speeds - but quite fast.

I have Googled it but cannot come up with a definitive answer.

Now I have the maintenance manual for it and I can probably get the LCD mask off to look at the power witch itself. But before I do I would like some opinions on the most likely cause and would prefer to avoid this if at all possible.

So any Toshiba / laptop folks out there any suggestions please.

A:Laptop will not power up

The power button is a likely cause and fairly common. The switch is a simple contact switch: it makes momentary contact between 2 wires to signal the motherboard. If you can find and get access to the 2 wires you can physically touch them together, or use a flat blade screwdriver to momentarily connect the 2 contacts, and that will test whether the power logic circuit is good and the switch is bad. If you make contact and it does not start then you can assume the switch is OK and there is something wrong on the MB side of things.

Before you start disassembly it is always a good idea to do a simple test (perhaps you've done this already):
First, reset the BIOS defaults: Remove power adapter and battery, press and hold the power button for 20 or 30 seconds, then connect everything again and try to start.
Then try with just the battery - no power supply.
Then try with power supply - no battery installed.
If none of the above works then you next want to remove the hard drive, CD-DVD drive, and RAM and try to start (it won't) but you may get some indication it is alive (beeps, info on screen).

Then add one stick of memory and test, then the hard drive, then the CD-DVD drive.
See what you find.

I went to turn on my computer one morning and the power button doesn't work.  It won't power on. I tried taking out the battery, unplugging the computer, and holding down the power button for a minute, then plugging it back in, and turning it on, but still nothing.  The light on the left side does come on momentarily when I plug it in.  I just bought it a few months ago.  It has a 3 year warranty.  Could it need a new powercord?

I have a customer laptop won't power on.

The report from the customer was that he went to plug the power in and put it in the wrong port and he said that he heard some sort of craking noise.

The laptop will not power on doesn't matter if the power cable is in or not.
I have tryed removing the battery for 5 min's.
Removing the RAM
Then Removing the hard drive.
In all cases the it didn't power on,

All that happens when you press the power button is that the light will go on for about 5 seconds and then turn off. There are no beeps. No sign of damage anyway.

The laptop is a dell latitude D600.
 

A:Laptop won't power on

If he heard crackling, my guess would be that some part of the laptop's motherboard is fried. Have you opened it up to inspect it yet?

I don't get how you could manage to jam the AC adapter into the wrong port though...

When my power level hits 17% my laptop completely powers down. Upon starting it up i receive a message that my laptop did not shut down properly. When windows starts, after lets says 2 min, I receive a blue screen.

Normally at 7% my computer gives me a message saving I should plug it in. At 5% my laptop will forcefully go into standby.

Under event viewer it says, "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

Hey people,

I recently posted about my laptop laptop ac mains adapter as it was flicking on and off and diagnosed it as a dodgy cable. Went out and bought a new one to try and fix the problem but the power still switches between mains and battery when cable is inserted. Have concluded that the connection in the laptop my not be working correctly and was just wondering is this a common problem and is it easily fixed.

Thanks

Hi

I buy Broken Laptops and Repair them ( not all ! ) as a hobby , the question I have at the moment is that I have a Laptop repaired and ready to fire up , but I do not have the correct charger / power supply for it .

It requires a 19V 4.5A supply , now I have a couple of chargers but they have a 19.5V 4.5A output , would that extra 0.5 V make such a difference as to blow the Laptop ! .

thanks

spike

No. That will be fine.
I bought a multi power supply with loads of different tips and voltages for fixing customer's laptops - they always forget the power supply and present them with flat batteries and then wonder why it takes a long time to fix them.
