I am not too expert on laptop motherboards but i have the knowledge to handle them.
i have this laptop which doesn't turn on. After testing i found that Vin is shorted
and following a schematic diagram i noticed that the cause is +VGACORE.
I removed L5 (CPU coil) which is connected to +VGACORE and short disappeared.
i used BGA machine to reheat BGA ic but short is still there.
is it possible by reheating BGA the short remains or do i missed something.
Thanks
