hi,
power button blinks 3 times and then stays ON when I connect the power adapter. The num lock/caps lock led flickers once and then OFF.
When I press the power button, the power button light turns ON but nothing else happens. No display, fan not turning, cpu/gpu doesn't heat up.
Tried flashing a few BIOS from the forum (not my cleaned BIOS dump) but no luck. No sure if my bios is corrupted. Which part of the board should I check?

hi,
Please help. When power adapter is connected, my laptop power button blinks 3 times, num lock/caps lock led flickers once and then off. When power button is pressed, the power button light turns on but everything else doesn't work (no display, fan not turning, cpu/gpu doesn't heat up). Tried a few bios files from the forum but no luck. Please help to get a good bios file. My bios backup attached.
