I purchased this laptop from fb marketplace
and the previous tech jumped 1st mosfet. maybe it got fix, then time comes by jumpering fried the charging ic?
tried to change mosfet but it does nothing 19v is not passing through 1st mosfet
tried to jumper again, I got 5vlp and 3vlp but 5valw and 3valw is missing
I suspect that the charging ic is bad? If so how do i test if it is bad.
Cant see any short or corrosions on board
