First off I want to say I'm sorry if this isn't in the right forum. I really didn't know where to put it but I badly want the help if there is any for my situation. I bought a hp pavillion dv4 entertainment laptop white from someone Saturday and All through Saturday up until Monday night the laptop was working beautifully. The laptop did seem to get pretty hot to me so I used a cooling pad that runs off the laptop's usb port. So I set the laptop down still on it's cooling pad last night and walked away for about 3 minutes. I came back and the laptop was completely turned off. So I tried rebooting it and I could tell that it was attempting to come on because the cooling pad fan would turn on strong but then it would stop and it would act like it was about to start and then nothing. I remember that the computer was on 34% battery so I had just plugged it up, it was plugged up when this happened. I also though that maybe it was the laptop's adapter itself that was not working, because I figured even if the laptop was low on battery I should still be able to turn it on and have it stay on and use it. So when I used an adapter I already had it came on right away and went to the windows home screen, but unfortunately maybe no less than 30 seconds later it had shut off again. Now it won't boot up like that anymore even from the new adapter. I let it sit over night plugged up with this new adapter thinking maybe it just needs a charge. Unfortunately when I went to check it this morning. I got the same result as last night. Also I forgot to mention the whole time I had it plugged in to the new adapter it had a little light blinking that's located in front of the laptop under an image that looks like a thunder bolt and the is no sign of life whatsoever with the adapter it came with. At least with the new adapter it has a blinking light and it attempts to turn on when I press the power button. Is there anyway at all that I could possibly fix this laptop on my own or is it a lost cause. I mean I've been using the laptop since Saturday for extended periods of time without so much as a lag or issue of any kind then last night it just shut off.

Ok I would take it back because It's so new but however you can try,

Every Laptop has Power Options These options are defaulted to High Performance. If you can get into Safe Mode F-8 Advance Boot up options select Safe Mode with Networking.

When its boots up go to Start|Control Panels|Power Options and select Balanced(recommended)

See if you can boot it up to Normal Boot after you completed the steps

Okay I've tried this but it won't work because I can't get the computer to come on so I can't access anything. It starts to light up and the fan starts going like it's about to come on for about 10 secs and then it just goes off.

Hi BreeLovesPc,

This certainly doesn't sound good, but here are a few things you could try.

  • Make sure that there is nothing plugged into the laptop such as a flash drive, external drive, printer, or mouse.
    Unplug A/C cord, remove laptop battery, press and hold power button for 15 seconds. Plug in A/C cord and attempt restart. Success?
  • Try to start the computer with just battery and no A/C power. Success?
  • If that doesn't work, plug in newer A/C adaptor and press on the connection where the power cord plugs into the computer (the AC power jack) and gently move it side/side and up/down while pressing the power button. Any action?
  • Each A/C adaptor should have voltage and amperage listed (example: 19V===4.5A).
  • Are both adaptors the same?
  • Do they match the requirements on the sticker or plaque on the bottom of the laptop?

If the CPU is overheating, the computer will shut off to protect itself. It should restart when cooled, unless the motherboard has become damaged over time from the heat.

Regards,
Brooks

I've tried all that was suggested above and none of it worked. When you say that it certainly doesn't sound good, what do you think could be possibly wrong with it? Also is it at all fixable?

Hi,

My thoughts are that it's motherboard or CPU related. Everything is fixable for a cost. You would have to take it to a few shops for some estimates.

Maybe others will provide additional input.

Good luck.

Regards,
Brooks
