Aahhh! You jinxed me. As I clicked to respond my mouse died and I had to pop in a new battery.
Interestingly, the mouse does not show under Power tab if I have my phone plugged in the USB - the phone takes over its place. Maybe that is a way to stop the OS from nagging me about my mouse? But it sounds too a la Windows.
Update - Nope. Mouse power monitor shows now after a small wait. Its not going to let me off the hook on this one.
Will have to let Swarfendor save us all on this one. I know so little about Zorin 15, it is embarrassing. I am still reveling in 12.4 and not planning on letting up any time soon. I am curious of what Zorin 15 Lite will have to offer, though.
Beware of this, however: https://bugs.launchpad.net/ubuntu/+sour ... ug/1798166
You MAY consider disabling UPower by running
systemctl stop upower
systemctl mask upower.
Not sure of the consequences of trying that are, though.
EDIT: Proofreading this post, I see a lot of "though's " and "however's" in it. I don't know why, though. I will try better next time, however.
