Hardware Switch with lots of problems

[OwenG123]

Hi,
I have a feeling that this switch may become a donor, It is water damaged and has a lot of issues. Just for laughs I thought I would see if I can get the motherboard working.

To cut a long story short, it now charges at 0.46A, no display or back-light.
This cap is shorted to ground both sides even with M92T36 and the cap removed, does anybody know what that pin does and where it goes?

THATS YOUR VCC LINE from usb port. check usb port pins or any cap between usb port fuse and M92t36 short

I thought it might be. The mosfet under m92t36 I guess switches vcc from usb to m92t36?
I removed these three and the short was still there so maybe there is corrosion under m92t36 or the mosfet that I missed.
