09/02/21, connected to PC via TV. Downloaded Event logs to my C:\temp.
Done a ‘powercfg -lastwake’ to find out why it woke last time, but there where no details…
Wake History Count – 1
Wake History 
Wake Source Count – 0
No obvious faults in event logs at 1st look, so disabled USB wake timers (apps etc that can waken pc), and disabled the Mouse’s USB device Power Management Tab’s ‘Allow this device to wake the computer’.
Have left keyboards as-is!
