Trying to repair a HP 830 G7 board where I found the Q7001 a low power mosfet blown probably caused by supplying current to a shorted capacitor from the 5V line -> I plan to locate the shorted cap with the usual lab PSU set to 1V and limted to 2-3 amps and a thermal camera.
Blown mosfet is shortcircuited and has a hole in its casing so I cannot read its marking properly hence my problem.
Looking in the only schematic available everywhere on the internet the Q7001 shows as being a PJS6416-AU N-channel mosfet but the schyematoic image shows a P-channel mosfet and also there is no gate voltage over 5V needed for activationg a N-channel mosfet.
Shopuld I install a P-channel mosfet there?
I have some new FDC638APZ SMD P-channel mosfets with same pinout.
I attached some pics of the board with its revision info, blown mosfet and screenshot from the schematic and PCB view file Q7001.
