Hello.
Notebook is completely dead, no response from power button.
Power adapter is ok and battery.
Tried clear CMOS, no response.
Motherboard is LA-8861P Rev 1.0
I found shorted PQ207 mosfet on battery charger section and i removed mosfet but still motherboard is dead (with adapter power connected).
Is anyone can give some suggestions or help with parts of schematic ,
like ''power tree'' or similar, cause definitely there is some
defect with power. There is no 3.3V to BIOS chips, nor voltages to CPU and
RAM.
Thanks in advance.
