Case study
HP 1000 HSLC laptop
Prob: Battery not charge. But showing on battery icon "Plugin and Charging"
Diag: checking on charging section of the board. saw that some PF indirectly short.
I changed charging ic but same. Still PF showing short.
Finally find a MOSFET was leak from Drain to Gate.
(Drain pe 19v, Source pe 18v and Gate pe 18v)
actualy Source pe 19v and Gate pe 25v hona chahiye.
Sol: Changed the leak MOSFET and Problem solved.
