She doesn't happen to have a standing desk does she or a power strip mounted under the desk?
The A/C power lines and Large motors in stand up / adjustable desk can wreak havoc on mice speakers hedsets ect, and cause odd behaviors, and if there is a power strip mounted near where the mouse it could also be interference, same for a strong radio source.
No, nothing like that. She uses a kitchen table, and the power strip is on the wall at the other end of the table. Good idea though. That'd make sense.
I finally did get into BIOS and I saw nothing apm or battery related, except to tell the time remaining.
it would be called power saving or similar usually S0 S3 S4 State options or eRP on/off
While reading the above posts I realized that the laptop is an older one or else I would suggest that if it has a touch screen issue and to disable it .....
My older Asus laptop had touch screen which I hardly ever used as I'm a mouse and keyboard man ..... one day I was using my laptop and the mouse cursor jumped to a particular spot on the screen and stayed there nothing could make it move ..... I changed mice ..... no go ..... checked the net for answers and nothing related to my problem ...... it would work sometimes and not others .... finally after a few weeks it stared doing it permanently on start up .....
Finally I had to take it to a technician who laugh when I told him my sad story and said it is your touch screen .... turn it off or I can fix it by replacing the screen ..... I turned it off in my settings .....
I know this is probably not your problem but just encase someone else has this issue it might help them .....
Good luck with your issue ..... it definitely sounds like a hardware issue .....
It is a touch screen! I wonder how to disable it on zorin though. Does anyone know? Is it an easy fix possibly?
If I remember it is a setting in your laptop ..... I was using Windows 8.1 or 10 at the time as that was about 6-7 years ago ..... I have no idea where to find it now but seems it was a hardware setting ..... you just had to remove a check mark if memory serves me and yes you can just check it again if that doesn't work .....
Try
sudo nano /usr/share/X11/xorg.conf.d/40-libinput.conf
in the file, goto the line
# MatchIsTouchscreen "on"
Change to "off"
Remove the # from the start of the line, to make the command active.
click Ctrl+o to Write to file.
Then Enter to confirm.
Then Ctrl+x to exit the file editor.
Then reboot.
