Shorted high side MOSFET for the PPBUS_G3H buck converter, so you get the DC in voltage on PPBUS_G3H.OpenBoardView — https://github.com/OpenBoardView/OpenBoardView

Re: 820-00138-a A1398
Schematics in this thread is the correct one. The touchpad connector J4801 in the schematics is wrong though, use 820-00163 schematics for the proper pinout.
The boardview in this thread is for 820-3662, it looks similar to 820-00138 but the SPI ROM and touchpad area are different. Use 820-00163 again to troubleshoot touchpad area.
The correct 820-00138 boardview may be available, but I haven't seen it yet. Most websites sell the 820-3662 but labelled 820-00138, be aware of this scam… (same for 820-3536 sold as 820-3476, 820-00163 sold as 820-00426 and maybe some others)OpenBoardView — https://github.com/OpenBoardView/OpenBoardView
