Chosen Solution

Once I press the Power button, it seems that my computer starts like always do. But, somehow, after a few seconds of normal activity, the fan switches off and the computer remains in a state of apparent hibernation. During this process, the screen remains off and black, and does not turn on. In addition, the LED power button stays on all the time and the computer does not respond to any key. My hypotheses are:

  1. Something is wrong with the fan (not probably).
  2. Something is wrong with the graphics or the screen (I don’t think so)
  3. Something is wrong with the BIOS (maybe the computer can’t load the BIOS, maybe there is a problem with the BIOS battery).
  4. Something is wrong with the processor (maybe there is a thermal issue or something worse). Any ideas or possible solutions? I will try to unmount the computer and clean the inside…and see if that helps. Thanks!!

Do you hear some beep when you try to start the laptop ? You can try to know what is the problem if you have some beep at startup with this link : http://support.hp.com/us-en/document/c02…

All right. That’s the news: I tried to reflow the GPU following this video on YT: https://www.youtube.com/watch?v=UgIEZzkG… Now my notebook is able to start! In the first start some checksum indications appeared and then some confirmation for contiue with the system loading. Finally, Windows 7 starts. Great. But, there are also bad news: I’ve got a problem with the FAN. It is OFF all the time! I don’t know what is the cause, but my notebook now make a beep when the main power connector is plugged in. It is only one endless beep. And It seems there are no help for this case! Any ideas? Thanks!
