PS: found now in my memory, i messed up with a moved resistor during bios chip removing and connected to it, hardly moved back in to position, or maybe replaced, that maybe open overheated, i will check it..

Resistors OK, found a damn short on the PMIC! Giant QFN IC, placed an inquiry to buy it.. difficult to solder, no space.. :-(

Can you post a picture of the IC and surrounding area

Best place for an Acer. It's there for a reason.

Photo took from internet, Red arrow is the P9145-T0NAGI PMIC (T0= Tzero), CYAN arrow is the cap where i injected current and a lot of draw and heat on the IC..

I minded that probably i'm in a big trouble, these chips are probably programmable, i found a mockery-datasheet with no useful info, is it possible to exit by such situations for you?
