Re: Lenovo B50-30
if the first photo was rotated 90 degrees anti-clockwise (as i should have done
) Im getting 0 volts on the right side of the mosfet P0302. This was the mosfet that was badly burnt, I replaced it using a mosfet from a donor lenovo board but Im still getting 0 volts. Do they have to be 100% the same or will a similar one do the job?
