If I just put the PC to sleep at night, and then wake it up in the morning, I sometimes find I am losing my mouse. Everything else is OK, but the mouse doesn't seem to work.
I then have to turn the PC off and on again, and all is OK.
Are you feeding it properly ? Maybe it's on strike for proper Cheddar.
Sorry, no sensible ideas on your technical problem. Have you checked whether it also occurs to your spare mouse ?
No, its a wireless mouse. Batteries seem OK although I will change them today, just in case. But I can't wake the mouse up by switching it on and off, or by pressing the left or right buttons....only by switching the PC off and on again.
Sounds like the transmitter plugged into the PC is losing contact,which is why I thought, batteries. Does pressing the button (if it has one) on that help, possible the same time as you press the one on the mouse ? Cycling the PC's power kicks the transmitter into looking for a mouse again, as it boots up.
Depending on which operating system you are using it may be a few more clicks to find it
Control Panel
Mouse
Hardware
Properties
Change Settings
Power Management
If you are using Windows 10 you can use
Settings
Devices
Mouse & Touchpad
Additional Mouse Options
Hardware
Properties
Change Settings
Power Management
But it may mean it simply doesn't support Wake features
