My old HP G62-b50SH wont start. The screen is black.

Hello Everyone!

I have a strange issue with my old HP.


The device was running perfectly, i'm unplugged the charging cable and leave the laptop (with the battery inside) at home. After i come back, the screen was blank, and the device wont respond. Even after a restart. I guess something went wrong during the hibernation process.


The screen always remains black, the WIRELESS button emitts orange light continuously, and the Caps lock button just no lights at all (like in the cases i found on the internet).


I tried a lot of things:

- Swap the two 4GB dual channel RAMs.

   (Not original of course)

- Place back the old RAMs

   (Not original neither, i buyed this machine in used condition)

- Start the machine with just one RAM

- Unplug the HDD

- Unplug the WIFI card

- Hard resetting when the battery and the power adaptor unplugged with pressing the POWER button for 15-20 secs.

- Press the FN+F4 for display select.

- Charge the battery to 100% (as suggested in a YT video)


All of this things failed, my device still wont start, and i'm didn't find any light emission error code like this.
