I have a fairly small screen on my ca. 1997 Pentium II laptop -- 1024x768 is all she'll do on the built-in screen. As a result, I need to keep things a little simple, but I also needed a monitor to warn if the battery is getting low and shut the system down before an unclean shutdown causes potential data corruption. A nice CPU monitor is pretty useful, too, since some software bugs seem to manifest as CPU usage going to 100% -- and, with only a little over 12 GiB available for root and /home (16 GB total storage, but most of 4 GB taken up by Windows 98), I need to also keep an eye on storage space. Here's what I wound up with...

The battery safeguard depends on four scripts, three of which use yad for an interactive notification, while the fourth produces a hard shutdown, without further warning at 1% battery life remaining (which is just barely more than it takes to actually run through an orderly shutdown).
First, appearing at 25% battery, is lowbat.sh:
Code: Select all
#!/bin/bash
yad --image="info" --text="The battery is low. Connect to power or shut down soon." --button="gtk-ok:0"
ans="$?"
case $ans in
0)
# exit
exit;
;;
esac
Second, invoked at 10% energy remaining, is verylowbat.sh:
Code: Select all
#!/bin/bash
yad --image="info" --text="The battery is VERY low. Connect to power or shut down ASAP." --button="gtk-ok:0"
ans="$?"
case $ans in
0)
# exit
exit;
;;
esac
At 3% battery (about two minutes of full operation) we'll meet shutdown.sh:
Code: Select all
#!/bin/bash
yad --image="info" --text="The battery is critically low! Connect to power and press cancel or save your work (quickly!) and press OK to shutdown." --button="gtk-ok:0" --button="gtk-cancel:1"
ans="$?"
case $ans in
0)
# shutdown
sudo -S < ~/.passwordfile &> ~/dumpfile shutdown -hP 1"Shutting down due to critical low battery!"
;;
1)
#exit
exit;
;;
esac
Finally, if the user doesn't initiate a shutdown or connect external power by the time battery capcity reaches 1%, we'll invoke hardshutdown.sh:
Code: Select all
sudo -S /home/dqualls/.passwordfile &> /home/dqualls/.dumpfile shutdown -hP now"Shutting down: Battery empty!"
Edit: there's still a minor bug in the battery monitor code; the low battery warning keeps coming up (for a long time) after reconnecting power. Working on it...
