I need to repair laptop that may have faulty mosfet. The mosfet is marked like
_
3 D
(3 with a line over it and then D )
or another also with E like
_
3 E
(the second line is like 3ITA or maybe 31TA)
Anyone knows what transistor is it?
5V is coming to gate on mainboard ( maybe because of a fault on the mainboard but maybe because it is P-channel.
In case it were P-Channel mosfet, if I use 19V to gate, will the mosfet survive?
