I'm just thinking out loud here, have nothing to back it up. Is there
any chance it's about our laptops attempting to preserve as much
battery power as possible by shutting things down in some kind of
sequence? Like maybe as soon as the laptop thinks the mouse might no
longer be needed, maybe that would be a reason the laptop would set
the mouse to the side by cutting it off somehow?
Only reason that comes to mind is that somewhere along the line, I
read something about laptops doing something like that. It's possible
I even got that impression from having stumbled upon a setting where
choices could be picked as to what received priority while on battery
reserve...
I really did read something similar to that, but am not sure where...
unfortunately. :)
Just for fun, I tried a super quick "apt-cache search power laptop"
inquiry. Received a few things so randomly tried "apt-cache show
apmd":
"Description-en: Utilities for Advanced Power Management (APM)
On laptop computers, the Advanced Power Management (APM) support
provides access to battery status information and may help you to
conserve battery power, depending on your laptop and the APM
implementation. The apmd program also lets you run arbitrary programs
when APM events happen (for example, you can eject PCMCIA devices when
you suspend, or change hard drive timeouts when you connect the battery)."
That gives an example that there is an active thought process at least
similar to that out there.. :)
