Wow it's been a while since I posted!
This is a weird case, it has a history of liquid spill a year ago but customer did not want to replace neither trackpad or keyboard.. fast forward for today:

I have verified all the pins are connected to the main board and the main voltages (PP1V8_AONSW_KBD_ISNS and PP3V3_AON_KBD_CONN) are both present, with and without keyboard attached.
Unfortunately, the keyboard does NOT want to work, caps lock LED not functioning as well as any...06-16-2025, 12:03 PM -

Sort of stumped here.
