Same issue. I submitted a feedback form. It seems like, from trying out a few things (although I'm not positive, and I would hope Microsoft would root cause this):
- If Smart charging is on Adaptive or On (limit to 80%), seems to correlate to no charging
- If docked through USB-C and without the separate power plugged in, no charging (even when the laptop is charging)
- If undocked and powered off, asleep, or hibernating, no charging
- The weird thing is that the pen, of all things, is charged!
- If I turn off adaptive charging, plug into the regular power, and power on the laptop...charging sometimes???
This is really frustrating.
