    computer turns itself off randomly

  • Gene Mean Jan 10, 2008

    I have replaced my AC Power Cord as I thought the connection to my computer was faultly, and therefore causing my computer to hibernate for no apparent reason. That has not solved my problem. I also notice now that my battery life is a lot shorter span than in the past. It only allows me to work for about 25-30 minutes tops. Do I need to get a new battery, and will that solve my problem of hibernation for no reason??

    Help me out if you can, thanks.

    Hi, I have the same problem. I have isolated but not solved it. The problem is either a faulty cable in the low voltage side of the AC adapter, a bad connection between the power supply plug and the computer socket or a bad connection between the computer power socket and what ever it connects to.

    I am going to start by finding an alternative AC adapter and will keep you posted with results

    My HP Pavillion laptop will operate for only 15-20 minutes, then it goes dead. I cannot even download a full album on iTunes, and have actually lost money when I turned it back on and tried to re-download songs (iTunes says there are no purchases to download, but I only have part of a song and/or album). I bought a new battery, but nothing changed. I do notice the motor gets very hot right befor it turns off. Any suggestions?

    Brand new Sony Vaio that came with Windows Vista turned off twice by itself.  I plugged the battery in and it didn't register that it was connected. 

  • Anonymous Jan 04, 2009

    the computer jus cuts its power randomly when not on charge. without warning, the computer just goes off, and i have to turn it on again from scratch. its like when you hold the on/off button for 5 seconds or watever. its fine when its on charge. When i turn it on again the battery life is fine so its not just run out of battery. please help!

  • joestyllo Jan 28, 2009

    same thing, I went through 4 power supply and usually twisting and manipulating the end to the insert part buys me a couple months (with wire heating issues). I know my gf left it on the bed so it didnt have ventillation for about a year but I think its in the mother board component where the power comes in because it does not shut off when its running on the batter (i.e. no power).

    So my guess is that there is an over charge, a short circuit causing this. **** loads of forum posts have the same problem, all I know is HP are dicks. When you send them the laptop they keep for a couple month and just send it back with the same problem, we send it back and the cycle continues until the warranty if done. Simple pretend they don't know to save millions of dollars in recalls and warranty fixes etc...

    What can we do? I hope enough people get together and do something because HP is over priced and you expect quality, thus they should take care of the paying customer! And don't get me started with their printers and ink. Those theifs fill the ink only 1/4 way and charge more for ink than a printer. If I would buy their original ink I would buy a new printe rink included each time it would be less expensive.

    And the software, they think their printer software is an operating system. It takes longer to install the software for my HP printer than it takes for me to format and install a fresh windows!

    HP is the republican George Bush of corporate greed. I am officially not buying HP anymore! I support their competitor ...

    P.S. for thise who's laptop shuts off, sometimes and only if your lucky, try to set your power setting (a link in your screen saver setting window) sometimes when your settings for putting you comp to sleep causes this model to shut down, in some cases it worked for me.

  • douglasknapp Jan 29, 2009

    Acer Aspire 3003LCi - it has been working fine for 2 years. Suddenly it started shutting itself off. The repair shop tried a new hard disk, new fan, finally said they likely can't fix it. THEN our daughter's computer - same model but one year newer started doing the same thing today. Both machines have added RAM - could this be causing more heat and forcing a shut down? HELP!

    Exactly the same as the original poster, Dell XPS 1530 just cuts out randomly.

    my pc keeps turning its self off can you help

  • Q-dawg May 11, 2010

    Great info! This problem seems similar to a heat sink issues others are having with this model. I took the laptop apart and and there was a lot of lent in there. After using compressed to clean it. The computer worked fine for a few days then it starting turning off again. I plugged the computer into a surge protector and the computer stayed on longer but eventually fried the power source. To date I have fried three power soucres (ac adapter). This seems to be unique compared to what others are experiencing. Does anyone have a clue what can cause this. HP said they can fix it for $300 but won't tell me what they're going to do to it.

Inspect fan operation and ventilation holes.
If they are clogged, power supply may be overheated.

I had the same problem. I installed a CPU temperature monitor and realised my CPU was overheating and that is why it kept on switching off. I opened up my ACER 5720Z and cleaned the vents which were (very) clogged up, even though my laptop is only 6 months old

Hi, there i own dell latitude d620 when i press the power button it appear led power light and not boot, and it off itself why is this? please help me....

Remove the Battery then clean the metal contacts on the Battery and in the battery compartment then press and hold the power button on the Computer for 30 seconds.
Next, reinsert the Battery and try to turn ON the Computer. If the Computer keeps turning off then connect the AC adaptor to the Computer then try to turn it ON.
If the Computer keeps turning off automatically even when the AC adaptor is connected to it then the issue is with the power supply unit and requires to be replaced.

The mother board has a battery if thats the one you took out you reset the bios, Try pressing the delete simutanuosanly after turning on the computer then in the bios goto boot device priority and select your hard drive press f10 which is the save and exit.

Computer turns off by itself

I have a toshiba laptop which was unexpectedly switching off. The laptop was 2 years old. I did lots of searching online to discover this is a VERY COMMON ISSUE. The problem is, dust blocks the heatsink. When I took my computer to pieces, I found a strip of dust half an inch (1cm) thick covering the back of the heatsink which prevented air flow. If your laptop is a couple of years old, this could be the problem. When I removed this dust, the problem disappeared. If you are computer savvy, then try the following - if not, take it down to a computer shop! 1) Remove the 5 screws holding down the heat sink cover and processor cover. These are on the bottom of the laptop, in the centre, at the back. 2) Remove the 3 screws which hold in the heat sink in place. 3) Remove the heatsink 4) Take the dust out 5) Re-assemble a note: be careful not to get dust in the thermal paste on the cpu - unless you have replacement paste. Good Luck!
