I recently updated the BIOS to S92 Ver. 01.18.01 (from 01.16.00).
Ever since, when I plug in a DisplayPort monitor to either USB-C port, I get a warning from Windows: "PC isn't charging".
This didn't happen before the BIOS update. No other updates were applied (e.g. no change to Windows). It's the same monitor as before (Iiyama PL2792UH).
The monitor is actually configured to NOT put power out through the USB-C (USB BC is OFF).
I have the laptop's power supply plugged in (150W, barrel connector) and Windows shows that it's connected (lightning flash on the battery icon in the system tray).
Given that the power supply is connected AND that the monitor isn't pushing power I wouldn't expect there to be an attempt at charging via USB-C.
Anybody else experience anything like this?
Thanks
