Battery life if you turn off Wi-Fi

Q: Battery life if you turn off Wi-Fi

I've got an older Dell Latitude that I've turned into something of a netbook. It has to only have a 4 cell battery because it only last's an hour and a half give or take 15 minutes (depending on brightness).

How much battery life can I save by disabling Wi-fi? I don't have just a switch on the side of the laptop that I can turn off/on. By disabling it, I would go into Network Connections and right click on my wireless connection and disable it there? Would that save any battery life?

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.

I spilled well-water on my laptop a few weeks ago and immediately removed the power adapter battery and drained the energy from the motherboard I then opened it up as much as I could to dry off what I was able Backlight laptop won't turn on my to My laptop is an Asus U A and I am not entirely sure how to open it up beyond accessing the basics RAM Hard Drive etc Even when I think I ve gotten every screw the casing doesn t seem to want to come off and I haven t been able to find anything online about opening this machine The problem is that after one week of allowing the laptop to dry with good airflow standing upside-down on a wooden desk with a fan blowing I turned it on to see if it would work It worked just fine for about ten minutes and then the backlight started flickering like crazy and went out completely At the moment I am getting around the problem by connecting it to an old desktop screen I had lying around but I originally purchased this laptop for use Backlight won't turn on my laptop at school Any ideas on if I could fix this It definitely doesn t have a warranty anymore so I wouldn t be able to send it in or anything like that nbsp

Hi Aerebes, I really don't fix laptops; only upgrade the standard parts as needed. I did a search and this is what I found so far: http://screensurgeons.mybigcommerce.com/asus-u57a-laptop-led-screen/

My Asus Q550LF crapped out on me. I was browsing when a whole bunch of black rectangles appeared on my screen, about an inch long. I restarted my computer thinking it just froze or something. I could occasionally get to the desktop page if I unplugged the charger but now it doesn't even turn on. It'll make one beep when I push the power button but that's it. What might the issue be and is it gonna be expensive? Because this computer has been one of the worst I have ever owned and I would just scrap it or something if it might end up being costly.
 

A:Laptop wont turn on anymore

How old is it? It sounds like it could be a multiple of hardware failures including the motherboard. The black rectangles sounds like what we call video card artifacting which means the video card is dying. But the fact that it is not even booting up could point to a failed hard drive. Again, it could be anything.

Asus is known for poor customer service but you could try giving them a call.

Do you know anyone who can do some diagnostics on it? I certainly would be checking out the hard drive.

My Dell has been acting up pretty recently (6 months old and still under warranty), and the battery does not charge past 80%. Once it get's near the 80% charge, it immediately fills up to 100%.

I've remembered using the laptop for more than 6 hours under moderate use but now it barely lasts 2 hours.

Please give me some advice because I'm really dependent on this laptop.

So I removed and cleaned my print head, waited until it was completely dry, then reinstalled it. I let the printer do its thing and when it was done I ran a head cleaning and a nozzle check. The test page came out perfect. The printer then asked if I was done with my head cleaning and I pressed the confirm button and the printer shut off. It will not turn back on either. I tried messing with both the plug in the power strip and the end in the machine. I know the power strip works because my computer is on it and fine. When I press and hold the power button I can hear very faint beeps or.... they could be ticks- I cannot tell as they are really quiet. It reminds me of when the car's alternator is dead but the starter is trying as hard as it can.

Any ideas on why it would work just fine for 10 minutes and then crap out?
 

A:Epson XP610 won't turn on after cleaning

Do you have a Multimetre that you could test the cable with??

Just to ensure you are getting proper volts/amps (clean power). The only other recommendation I could make is try and unplug the printer.. Press and hold the power button for 15-30s, tap it a few more times for good measure, and then plug it back in and see what happens. Sometimes devices just need a good power drain.

I recently bought a used dell c640. It worked fine but there was no charger with it so of course it sat dead for days. Until I bought a brand new adapter/charger. I've had it plugged in for about an hour. The battery light is on but sometime it will go off. If I push the battery in a lil it turns back on. I tried turning power on without battery installed and the on light and little lights by the power button come on for a few seconds then go off. Any idea what's wrong? I don't think it's the cord like I said new and the lights wouldn't come on until I plugged it in. Please HELP!

I have a Dell Inspiron laptop, it started randomly crashing but it would start right back up no problem. Then It started getting more and more frequent. And then it started not turning back on right away after crashing, but it would eventually turn on after a little while. But now it won't turn on at all. I tried removing the battery and just running it on the charger, but that changed nothing, I still did it. Anyone have any ideas?
 

A:Laptop crashing, now won't turn on at all

The hard drive is probably corrupt from all the crashing. If you can, have someone remove and re-install the memory and remove the hard drive to see if the laptop comes back to life by lights turning on and the screen starting to display without the hard drive installed

I've been having an issue which started this morning. The previous night, I forgot to plug in my Dell Inspiron N5050 after using it. I woke up to find that my battery had died (obviously). I plugged in the laptop, running Windows 7 HE 64 bit, and turned it on. It booted normally and I was able to do all of my tasks as needed. Then I noticed my problem. The battery icon down on the taskbar showed that the device was plugged in, but was not charging. It has stayed at a constant 2% charge for more than 24 hours now. The Battery Meter stated that my battery is performing normally, so I ruled the battery out as the cause. The adapter I am using is the default one that came with the laptop when I bought it, and it appears to be functioning normally as well. What could be the cause of this incident, and what can I do to fix it?
 

A:Battery Stated as "Plugged in, Not Charging"

Most likely you have a bad battery. Dell has had whole series of batteries that they shipped out in a not fully functional state. I have an HP laptop (about 8 years old now) that the battery took a "steamy one" and it will no longer charge properly. You can try this trick (it may not work, but worth a try because did work for me a couple times): power down laptop and take the battery out for 30 minutes; replace battery and plug in charger but do not power on; wait 4 hours of charge and power on. I had it work a couple times that it gave a full 100% charge. Again, if it doesn't work then sorry, but at least you tried.

A:Monitor hooked up to tower, but doesn't turn on

If no standby LED on monitor, is there a separate on/off switch on the side of the monitor?
With LG there are usually manual buttons for CH+- & vol +- plus On/Off (although I have seen monitors with no on/off at all.)
Also check for 'hidden' buttons on the front lower edge of frame or under the front (right) edge.
I would try a different mains lead/cord that is known to to work, also check for a fuse in the plug, could be missing, or isolated with plastic foil.
Even with no inputs the monitor would show a 'No Signal' sign if it was working.
If no 'standby' LED and you have a separate AC to DC adapter block then that could be the problem. All monitors I've seen have a direct AC connection though.
If it then does work, the on-screen menu will need to be selected, and 'input' changed to HDMI.

Hi, I'm having a problem with my Dell Latitude E6400. When I'm not using it for a while the screen goes black (like into a sleeping mode) like all computers and laptops do. But if it stays black for a little while, and when I go to get back on it and move the mouse around or press the keys the screen won't turn back on but the computer is running because the light on the keyboard are lit up and I can hear the fan running. The only way I can get the screen back on is if I shut it down by pressing the power button on my keyboard and turning it back on.

Can anyone please tell me what to do or what is wrong with it. That would be much appreciated. Thank you

Hi you all!

I have an Asus Laptop, last generation i7, 8gb... almost nice. Code: N550LF

Problem: I have to work all day with my laptop, with graphic software and so on.
Almost 10/12 hours or more per day. In my old Dell (I had it for 5 years) I changed for this reason the battery every year.
It is extremely important for my work, even if not everyone cares about battery.

Requested solution: what can I do to preserve (as much as possible) the battery?

What others said: A friend of mine told me to always plug in the computer, because the computer doesn't charge the battery when it is full. In this way I can preserve the battery.
The Asus website doesn't give any advice about it.
The official support by mail told me to not plug the battery when it is 100% charged. This could be dangerous. So, no way to preserve it.

And in your opinion?

Thank you in advance
 

A:Battery advice

Batteries these days like to stay between 20% and 90% charge.
Leaving the laptop/device plugged in when it reaches 100% does no damage, as most devices have an automatic charge cut-off. So you won't over-charge your batteries.
The problem is, that you're keeping the battery between 98-100% charge all the time, when this is not a sweet spot for the battery at all. It will degrade very slightly faster.
Therefore, in order to keep maximum battery life, keep battery between 20-90% charge.

A:Laptop turns off or won't turn on Unless holding down certain keys

My first guess would be a faulty keyboard. Have a look in Device Manager and see if it has any exclamation marks next to it. Follow the route, Control Panel, System and Security, System, Device Manager. Replacing a keyboard can be cheap or dear and easy or hard depending on your make of laptop. Has it ever had a good clean out since new including vacuuming the keys to remove fluff and crumbs? If anyone has spilt some liquid on the keyboard that's another potential cause of the problem.

Anyway, the Dell BIOS has an option for HDD mode, it's in there.

Hi I have an older PC which I gave to my mum It originally ran Vista but I bought and installed Windows Ultimate around weeks ago after it had been inactive for months It was running great but a couple of weeks ago it just started hanging for no real reason Also at startup it would say that the computer had not been shut down properly even if it had This was only when it was switched off at the wall not after checksum defaults loaded" replaced error battery after - "cmos a restart or when the PC was left plugged in and switched on She only "cmos checksum error - defaults loaded" after battery replaced uses the PC to look at You Tube and some webcams from her grandkids and that s it she s not very computer literate Initially I left Windows repair to run overnight but when I looked at it the following morning it was still in the repair screen so I assume it had hung I spoke to a local repair shop and they suggested I test the RAM test the hard drive and replace the CMOS battery The RAM and hard drive checks went without any errors and after I replaced the battery the hanging stopped I played with the computer all evening and shut it down as normal and switched it off at the wall Next day I thought I would start it up just to check it and I was faced with a quot cmos checksum error - defaults loaded quot message I thought that was strange but maybe the battery was dead so I swapped it over with one from my perfectly working desktop to try it out and my desktop worked fine but after shutting down my mum s one it had the same problem when power was pulled So battery was ruled out Incidentally I will say that I reset the BIOS date and time every time I was faced with the error following up with a save and exit It worked fine until I unplugged the computer I then moved on to the BIOS and set it back to default and the same again After this opened the case and used the jumpers to reset the BIOS to default again but no difference My mum will not leave it switched on at the wall constantly in case it self-combusts same with her washing machine TV lamps etc otherwise I would just do that and ignore it Is there anything else someone can suggest that I try System Shop bought by Mesh Motherboard is an ASUS PSN-E SLI gb Ram - samsung gb hard drive - ASUS Thanks for any help nbsp

Hi everyone, I need your help urgently!

I have sony Vaio laptop which has been working well. Recently its charger had a minor explosion and broke (it happened when I plug it in to the outlet as usual). So I replaced it with a new one. However, the light on the new charger was blinking whenever I plug it into the laptop and turned solid again when I unplug it.

Could you please help me fix this? All my assignments and works are in this laptop and I need it very soon.

Thank you

Ps. I have tried removing the battery and it still doesn't work. Also I won't be able to try another charger.

Hi,

I have been trying to find a replacement battery for my HP G70 laptop. On the old battery it says to replace with battery 485041-003 but there doesn't seem to be any HP batteries and the names on the batteries and, indeed, the companies who are selling them, are companies that I have never heard of. I have looked at the reviews for most of them and there are mixed renews but a lot saying the batteries do not last as long as the old one. Given that anyone can set up a ficticious company and call it co.uk, which company in the UK do you recommend?

Perhaps it's overheating a bit due to dust build-up? I have a DSL modem/router combo and it's pretty warm. Since taking it apart is a bit of a pain, I use compress air & vacuum cleaner on it from time to time.

7 years does sound long, so might be better to replace it and give yourself the peace of mind.

I've been blowing through graphics cards about every 12 months. Even with my new system it's been the same. I do play a lot of graphic intensity games. Could that be the reason for their early demise? The latest casualty is my GTX 560.
 

A:The average life of a GPU

A GPU's lifespan is at least 3-5 years. Hell, if you take care of your components it will last as long as you need it to in most cases. The fact that your GPU's are dieing in a year is strange. If this has indeed happened to all of your GPU's it is safe to say that the operating conditions inside your PC may not be too good. Or, you may just be burning them out? Do you SUPER overclock them or something? What sort of operating temps do you usually get?

I got a sony erricsson Xperia X10 for over a year and now the battery life become awful. If I plugged it in through night then unpluged it at 7 am, but it was about to 0% by 11 am and I was getting a warn to recharge it. This has been really awful. I don't use it as my basic phone already so there are only several apps on the phone. The email wasn't set to push and I only refresh the emails when I want to check them, so its saving some battery, I have done the same with facebook, and the weather. These are the only apps on my X10. I was told to get a new extra battery probabaly a mpj one.
Wondering whether the battery is the culprit and my stock one is going to die completely?

I have an Acer laptop I bought last January Wear? Minimize Battery It s a Minimize Battery Wear? month laptop and someone told me that I should be removing the battery when I am using AC power I was hesitant at first so I installed a software called BatteryBar Pro Upon installing I was surprised that my battery wear was already at Minimize Battery Wear? I was surprised that I had already wore of my battery in just months Now I am worried that it will not last longer as expected I use my laptop for coding gaming and browsing mostly on gaming and I always run on AC power while the battery is plugged in I tried some suggestions like removing the battery while on AC but when I did my laptop did not power up It does not open if the battery is out and AC is plugged in I always put my laptop on an elevated stand I constructed when using it but is this enough Are there any other ways to minimize my battery wear Thank you nbsp

A:Minimize Battery Wear?

If your laptop allows you to, some laptops have an option to confine the battery to between 20% and 85% or something. That'll reduce wear if you can enable that. It'll also help if you manually do that as well.

Li-Ion/LiPo "wear" is well documented and the causes are well known for consumer chemistries.
Storing at high temperatures will increase degradation.
Storing at 4.2v/cell (fully charged) will increase degradation.
Keeping it below ~3.0v/cell (discharged) will degrade it.

So, in general, spend as little time as possible depleted or fully charged. If you fully charge it before leaving for the day, then start using it within a few hours, the wear is very minimal so you shouldn't worry about fully charging it if you're planning on using it soon, just don't store it for long periods fully charged.
Likewise if you leave it fully depleted for a long while, that will also accelerate wear.

If you need to store it, 40% charge (3.85v/cell) is commonly recommended but there is very little difference between storing it between 20% and 80% charge. Again the only times that storage can heavily degrade the battery is if it's fully charged (4.2v) or fully discharged (<3.3v resting)

I have an XPS M1530. It was displaying the message about battery can continue to charge but is reaching the end of its usable life - for about a year. I never operate the laptop without the AC adapter. I went to turn it on and it turned on and then immediately shut off. Then the AC light turned off. Now if I unplug the AC adapter from the computer, unplug the AC adapter from the wall and plug it back in the light will come on. Then as soon as I plug the AC adapter into the laptop the light goes off. Laptop does nothing/completely dead. I have 2 Dell AC adapters and both behave the same. I have tried it with and without the battery and same issue. Do you think a new battery will fix it? Any other suggestions? Thanks.

Hi, I have a msi CR410 that is working perfectly last night. Tonight, When I turned it on (plugged to adapter ) it didnt turn on..the battery light on my laptop is on and the adaptor's light is also on.. I tried the suggested on taking out the battery, pressing the power switch for 30 sec then put battery, plug it and press power but it still didnt turn on. After that I let the laptop be plugged to my adaptor just to see if the device is just power drained but after a while I saw that the battery light indicator on my laptop is also gone. When I touched the adaptor it was not hot not like before that its hot. This time its not hot nor warm, just no temperature but the light on the adaptor is still on but the battery light on my laptop is now gone too not like earlier.

The title says it all. I recently started playing Medal of Honor and Battlefield: Bad Company 2 and on both games I get a frozen screen with looping audio which forces me to shut the computer down via the power button.

after doing some searching around on the net and trying various solutions, I have determined the next step is to disable on board sound. I know this sounds like a noobish question but, is there any way to get sound out of my computer? is there a BIOS setting that allows me to disable the on board sound but still get sound out my PC? these 2 games rely heavily on being able to hear what is going on,

I have an ABIT IP35 Pro with no secondary sound card.

thanks.
 

A:Can I get audio if I turn onboard sound off without a sound card?

No that'd be impossible. if you turn off the onboard sound, how are you gonna get some sound delivered to your speaker or headphone?

you should try disabling the onboard sound and check if it fixes the issue. if it did, also try to uninstall your current audio driver and install the newest one.

looping audio does not always means the onboard sound is faulty. it usually goes on loop because that portion of the soundtrack is already loaded into RAM. therefore it still plays even when the computer froze.

the problem might lies in other thing such as video card or overheating CPU since you indicate it only occurs when you're playing games.

A:Looking for "techie" ways to extend battery life

Removing the HDD and booting from a flash drive is probably the worst decision you can make. Flash drives have very slow speeds (even though they are flash memory, they arent fast) and very little capacity. Keep the HDD.

There are only a few more ways to improve battery life other than dimming your screen and adjusting the power usage settings. Under-clocking the CPU is really done by the "power saving" mode.

Try these suggestions:
1) Run this tool: http://support.microsoft.com/mats/windows_battery_power_settings
2) Turn of your network adapter. There is usually a switch on the side of the PC that toggles the network adapter on and off. That will save you a ton of power. Also make sure bluetooth is off. I dont think your older PC will have it, but just make sure.
3) Use this tool to remove any unnecessary processes from start up. This will speed up your computer while also reducing the amount of processes that run (thus reducing CPU and RAM usage).

I can suggest other options, I just need your OS. If it is Windows 7, it is easy too, if it is XP, I cant really help there since I forgot the OS.

The humming from last night is replaced by a low pitched squeaking noise each time the fans twitch.

Hi, does anyone know what the problem is? I took out the screen of my old laptop, and put a replacement screen in. The screen its self (Samsung) is exactly the same model as the old one, except the inverter board looks a bit different. The laptop turns on fine with no screen plugged in, but when when I plug the new screen in, the only thing that turns on is the power supply light. I tried removing the new screen and it turned on fine. It's only when the screen is plugged in when it doesn't turn on. Is it because it's the wrong inverter board? I still have the old one. Should I just switch the boards? Thanks for all the help.

Make sure you have not switched the power LED and power switch wires. This caught me of guard once, took me a few minutes to realize my mistake.

To clarify, you are using the manual for pin-out configurations?

I recently took my computer apart to clean the fan. The computer notified my that the fan was malfunctioning and would turn off and not fixed. I found an online tutorial to show me step by step instructions to disassemble my computer in order to clean the fan. After all said and done computer back together. The computer wont turn on. Does nothing in response. Computer turned on fine before. Everything is plugged back in and screws in place.

Hi;
I have a 11yr old Dell Inspiron 8100 Notebook computer. It started shutting down mysteriously while working, and sometimes shuts down a second or two after powering on.
I was planning to scrap the thing, maybe try to sell it for parts on Ebay, but decided to take one more look.
Today I found that the CMOS battery (reserve battery) is bad. It is leaking but has not damaged anything.
Could the fact that this battery is bad (maybe shorted) cause the computer to shut down as I described?
Since I have the whole thing dis-assembled I can replace the battery easily. I found them on Ebay but not sure I should buy one there, since it could be an old battery that is no good.
Any ideas?

Thanks

How old is the HP? If its been a few years since you bought it, you might try re calibrating the battery from the BIOS, most HP and Gateway computers have a utility inside the BIOS for calibrating the battery. If not, let me know and I'll see if I can find one.

Hi friends

Mine PC is running on a AMD quardracore, Gigabyte GA-MA785GM-US2H, 4 GB DDR III 1600 Mhz Corsair Ram & Power supply along with 8400 GT nvidia . This PC has been OC to 3.2 ghz and is currently working at 3.2 ghz.

Recently I was getting BIOS notification to change the battery as everytime the BIOS had to be reset.

I changed the battery 3 days back but again after a day I again started getting the same notification of changing the battery.

Pls tell where could be the problem.

Regards
 

A:CMOS battery problem

Was the battery you replaced the bad one with brand new? Also make sure it is a 3V battery and to be safe, make sure it has the markings 'CR2032" on it (that is what mine has). Other batteries of the same size and voltage MAY be fine, but I can't really vouch for them. Also, if you have one, it might pay to check the batteries voltage with a multimeter.

Also, if you buy a new one, it might pay to make sure that it is meant for a computers motherboard, as some may or may not be, just to be on the safe side. I don't really know a great deal about these batteries.

I recently purchased an Asus N56V Series laptop. The laptop has impressive specs, including an i7 Core and a Nvidia GT 635M graphics adaptor, so I can understand it having a below average battery life. However, I am only getting 1 to 2 hours of battery life on it, even when I am not running processor and graphic intensive programs. Product review indicate that will battery life for this laptop is below average, the battery should still last 4 hours under normal conditions.

Is there any reason why my battery life is so limited? Has anyone else had similar problems with this model of laptop?

Thanks for the help.

Hi there I have a Dell Inspiron won't on connected trackpad is turn Inspiron N4010 if n and recently my speakers stopped Inspiron N4010 won't turn on if trackpad is connected working At first it was just one of them but later the other stopped working too Everything in the OS seems to be right the drivers are installed etc So I decided to open it so I could see if the connection on the motherboard is alright And they were so couldn t solve that Anyway the big problem came later When I plugged the three ribbons attached from the top panel to the motherboard one for the powering button another one for the keyboard and the last one for the trackpad and put all the screws back in the laptop didnt boot up So after playing around a bit to try different possibilities I realized that is only when I connect the trackpad ribbon that the computer doesn t boot If it s unplugged there is no problem Searching for a solution I found this on another post on vb topic Add techspot com at the beginning and html at the end cause I cannot post links But that works for a different model and implies breaking a sensor which I d rather not doing So I would like to know if anyone knows the solution to this or if there is anybody out there with the same problem and had success fixing it Thanks and regards nbsp

A:Inspiron N4010 won't turn on if trackpad is connected

You have probably shorted or damaged one or more of the ribbon cables wires. Did you release the ribbon cables properly by releasing any plastic clips, or just by pulling on them? A Windows re-install might have brought the sound back to life. An errant Windows update might have caused this loss of sound. Now you have really messed things up

I recently got this computer from a friend so I have no idea how long this has been going on. Probably why he got rid of it. I will plug in the power cord and try to boot with the battery in and nothing will happen. If I reach under the laptop and remove the battery and then try to boot up it comes on like normal. I can then put the battery back in but it makes no difference after that. The battery is completely dead. Does anyone know if this is a common problem with a bad battery or what. The computer is a Dell Latitude D630. If I knew that putting a good new battery in it would fix it I would without hesitation I just need to know if that is the problem or is it another glitch. If anyone knows the answer I would appreciate if they would pass it on. Thanks

A:How do I turn my PC into a gaming system?

What kind of motherboard do you have? It'd let everyone know just how much you can upgrade it.. But I honestly think you should get a whole new computer. I can't see your motherboard being able to take any Quad-Core (or more) processors. Merely a guess atm though.

If you don't know your motherboard-- http://www.crucial.com/systemscanner/ --just download that and it will tell you.

If you do get a new computer you can safe your hard drive, cd-drom, power supply and case and save a few bucks. So all you'd really need is a Motherboard/CPU/GPU.. The power supply is a maybe, It depends on how many watts it is and what kind of connectors it has. Another thing you could let us know.

Have you tried a hard start? Disconnect the battery and power cord if plug in. Then hold the power button on the laptop for 30 seconds. The either replace the battery or plug and try and start it. This may work. If so you may want to run a system check on it after if it boots. Other then that maybe someone here will know a little more to help you.

Hi.
I have a Compaq Presario R4000. It's around 6 years old. Until recently it has worked as well as any other laptop with the usual software problems. Yesterday I tried to switch it on and all I see is the charge light flashes once for around 1 second then goes out. No response at all from the machine. Tried running it without the battery but still no response. A friend told me that it may be the battery and that some laptops won't run without a battery inserted.
Any ideas would be appreciated.

Cheers.
 

A:Compaq Presario R4000 won't turn on

The motherboard is probably fried, after 6 years. Also, the CPU cooling heatsink/fan could be bad or the thermal paste or pads could be burned. If the battery is the original it is in long need of replacing...

"that some laptops won't run without a battery inserted"

Not exactly true. If the AC adapter circuits are faulty, maybe yes. Otherwise, it is not true. If a battery shorts, it can keep a laptop from powering up

I sent my laptop in to be serviced under warranty because the keyboard would not work. was denied service because of water damage but now my screen doesn't work, can someone help
 

A:My screen won't turn on after service was denied on warranty due to water damage

Water can destroy a laptop or any other electronic device. Chances are that the water sat underneath the keyboard and flowed onto the motherboard where it dried causing corrosion and damaging the motherboard permanently. You could take the laptop to a repair shop and they could give you a repair estimate. Of course, you will have to pay for this repair. If a liquid is spilled on a laptop in the future, immediately open it and turn it upside down. This allows the liquid not to hit and pool on the motherboard, or in a keyboard

Hello Everyone!
Ive been facing a peculiar problem with my Dell inspiron mini 270 of late. Its power light wont go off even after I switch off the laptop thus indicating that it is still being charged! What is even more strange is that in such a state I cannot restart my laptop until after the power light goes off on its own after a few hours. After repeated attempts, I have come to understand that this indicates that now the battery is discharged. Now when I put the power adaptor on and switch on the laptop, it starts. This effectively means that every time I charge the battery and switch off the laptop after some work, I HAVE to wait till the battery is completely discharged to start the laptop again. Guys, guys, I am at my wits end and have extremely close to tearing off my few remaining strands of hair. Any clues anyone?

I took out the battery and ran just on mains and everything runs fine and cpu is back to normal, putting the old battery in also enables the laptop to run OK.
Thinking the high cpu usage might be malware I ran Malwarebytes and Combofix but they found nothing.
Has anyone any suggestions as to why the new battery is giving these issues, never had any problems with other batteries I have fitted to laptops.

Tell us more. Setup. Components. Power supply. Enough for us to "mentally see" what you have, and where you obtained it.

So i have an HP G62x - 400 and i accidentally cracked the screen. i got a friend to replace the screen for me with the screen that i bought. since he returned it to me, it wont turn on. he had no idea what happened and is a trustworthy guy and i know he didnt (intentionally) tamper with anything. it shows that it still revieves power with and without the battery in. its more or the less the power button doesnt do anything. if anybody has had this issue before, or knows what may be the solution, please let me know

A:Won't turn on

The power button assembly has to be removed when the LCD screen is replaced, so it may just be out of line, or not positioned properly. At worst, the motherboard could be damaged

I recently installed a new Power Supply, and although I'm fairly certain I have my power button's power plugged in correctly, it doesn't turn the computer on when I press it. I've been making a habit of turning the PSU off for a few seconds, and then turning it back on to start up the computer.

Before I do this for too long, does it cause damage to the computer in any way?
 

A:Is it unsafe/will it cause damage to turn the computer on from the PSU?

It's unlikely it will cause much damage to your computer (maybe the HDD if you do it too often while the HDD is still being accessed) however that is a very good way to kill Your PSU especially if it is non-pfc. Every time you do that it creates an inrush current that the PSU circuitry must absorb overtime this can be damaging to various components in the PSU (mainly capacitors and rectifiers). Also the system should not turn on when you turn on the PSU unless the power button is pressed in an ATX board so you may have a short somewhere which could cause serious damage to your computer.
