Hello,

I'm newbee in electronic repairs, but I really want to learn someting. My gamepad is bricked (it stopped working during update installation) and I decided to disassemble it for inspection. Battery is ok - 3.5V (should be 3.7 but it wasn't charged for a while). Battery is charging when it's plugged via micro USB (measuring on battery connector gives me 3.74V).

I was checkig randomly on components and I think I found 2 faulty (i assume) MOSFETs. There are several of those in this area, all of them have (about) 0.7 voltage drop (when mesaured in diode mode).

I mesured the values on same components in this area and I discovered that 2 of them are shorted. This components are 3 pin (I assume) mosfets, with "MAK" printed on them, however the "K" letter is horizontally. Next to the top leg there is one dot and 2 dots next to the bottom leg. Midde leg (on the other side) has no inscription.

Multimeter in diode mode.

Measurments on good component:
- Red probe on the top leg (with one dot), black on middle -> 0,659 voltage drop
- Red on top, black on down -> 0,658 voltage drop
- Red on bottom, black on middle -> 0,7 / 1,2 / OL (depends on component I measured)

Measurments on presumably faulty component:
- Red on top, black on middle -> 0 voltage drop
Rest of measurments are the same.

Any suggestions? Are these components bad? What should I do next?
