Re: dell 2007fpb no power
the marked fuses are ok
but the 3a fuse on the right no read
it was between 500 and 600 but i changed it when i measure volt again
i found that 19v downed to 12v
i changed it back with the old one no thing new.i changed the power supply board with another one now 19v back again but no 3.3v or 5v or 12v...
