Cześć.
Mam podobny laptop i podobny problem.
I have a similar laptop and a similar problem. Mine is an HP Envy 15-fh0023dx, but the same LA-M798P Rev. 1.0 motherboard.

I have all the voltages, the APU gets warm. The BIOS has also been replaced several times. The EC chip has also been reflashed. There's no schematic available, nor is there a boardview online, and the situation looks hopeless,...
