I have been fighting random system controller communication issues.
Reform-Check
Leaving the system on or off plugged in to power or not the battery level in the OS will go to zero and the keyboard controller will show a T . I can not narrow down how or when it will error out.
To reset it I may need to flip the hardware power switch one or more times.
Is there a way to reset it via the command line?
I have not reseated cables and screen position does not seem to effect anything.
Thank you for any reccomendations.
