    How to determine SoC or processor short BM5387 Rev 1.2?

    How can I easily determine SoC or processor shorted laptop, when there is no power or display it is completely dead? Board is BM5387 Rev 1.2. Two of the coils near battery connector is shorted, one side 000 and other side 012 readings. Capacitors in that area also shorted similarly.

    The two left coils are short. I have 19v up to the cap next to the first coil on the right. No 19v. on the coil all other coils have no output. The group of caps and area around the two coils is shorted to ground.

      Check resistance to ground on pin8 of bios chip. Findout the two coils are connected to which line.
