Using the latest Windows 10, this mouse keeps disconnecting, usually upon exiting sleep mode. But sometimes even in the middle of usage!
I've noticed it happens much less after the computer gets restarted. The more the computer stays on, the more likely it is to happen.
Also, it seems to happen a lot while moving the mouse during videos.
Contacting Logitech was futile. But their products usually work super well, so hopefully this can be solved.
