Hp pavilion dv7

[Joseluislee]

Hi, i need your help guys. Here is my problem:

When I turn on my laptop it doesn't anything no even bios. I already tried everything from this forum; unplugging the laptop and bios the battery, pressing buttons before turning it on, unpluggin and pluggin rams and hdd.

Strange things happened trying to fix it:

-If I plug just one memory ram the laptop turns on for few seconds and then it tuns off. I have 2 memory ram ( 4 gb and 2 gb)

-Bought 2 new memory ram (2 of 4gb) same behavior

-Last i did was to unplug the bios battery and leave it for 6 months (I gave up trying to fix it). Turned it on yesterday and the everything worked, then restarted it due to windows updates and back to the same issue.

Please help me. TT

Thanks

Regards

Welcome to the HP support community.

Recover the BIOS using a keypress combination

1. Turn off the computer, and then connect the power cord.

2. Press and hold the Windows key and the B key at the same time, and then press and hold the Power button for 2 to 3 seconds.

   

3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
