Hello,

"repairshop" destroyed bios chip physical so i need a working full 32MB dump please to programm a clean chip.
N20C11 PH317-55
Serial: NHQB7EG007242099BF3400

Already tried bios from Acer homepage without any success or can this be any other fault?
Also not sure if they did anything to the EC chip because there was flux too...

Thank you my friend but still the same fault. :-\
Anything else i can check? I get loading LED and power for 3-5 seconds before turning off. Voltages on bios are present and thermal cam shows that PCH gets power before turning off. So somehow the system tries to start up.
Strange behaviour i found is that the power ic at PU1801 SY8288RAC has 30-40 c with plugged in battery and with power supply connected too i get a cheeping noise.
