Re: programming kbc msi ms-17f21
Hi reformatt thanks for answer , the laptop came with no power at all , after i checked, i detect a short on coil of 3.3v , after that i inject 1v on that coil and pch get hot immediatly and i bought a replacement from china , after i replace pch now the motherboard turns on but with no display , i checked that the motherboard has 3.3v, 5v , 1.2v and the voltages of cpu and GPU, thats why i think i ned to reprogram kbc
