dude BIOS makes the notebook dead. EVEN charging LED.

now check every component and coils for short to GROUND.

Inject voltage there if you find any. check and see if it gets hot.

If you find that HM Chipset gets hot , your done BGA work required.

start with bios and check with oscilloscope

first search sieguntur repair on youtube videos for better understanding of mobo architecture then you can start repairing

I think this is not a bios problem because there is no 19v in PQ26 which is n-channel power mosfet, there should be 19v in there I think but I only got 1.3v. If I don't have 19v in mosfet of 3valw and 5valw it will not generate 5valw and 3valw and 3valw is the supply voltage of bios for it to function so that's why I think its not a bios problem.
