Hi all, I'm trying to get the USB_ALWAYS_ON toggle between AC_ONLY and AC_AND_BATTERY working, so I'm asking if anyone has any notes on the EC registers (X220 specifically, but broader notes welcome). I've got some diffs from the Lenovo BIOS but I can't identify the flag.
I think that the non-functional 0x0D flag in the original USB_ALWAYS_ON patch gets fed straight to the charge controller, and that might explain why it behaves a little weirdly. Alternatively any other ideas are welcome too! Cheers, Nathaniel.
