I was setting up power saving on my Thinkpad last month, and I noticed the same as you. I think I set AUTOSUSPEND_USBID_BLACKLIST in /etc/laptop-mode/conf.d/usb-autosuspend.conf to prevent the mouse being switched off while on battery. I don't have the laptop to hand at the moment to check. If that is the cause you're looking for, it won't happen while on AC. Does it? (I seem to be writing backwards this morning. I hope it's clear enough.) -- Regards Peter
