Post by gurmeet singh »

checked and found board with no ac_ok from the charger ic . so no generation of 3/5 volts . checked ac_ok converted to ac_in# through a fet q 4001 as drain stays always high . so grounded this signal and bingo got 3/5 volt generated. but no display now psu reading going up to 1.40 amps and still . reprogrammed bios by different sites but no success . replaced cpu and success now got display .
