So, in the Linux case:
-- some machines use "BAT0" instead?
-- shell("cat /sys/class/power_supply/BAT1/status") returns either "discharging", "charging" ,"unknown", or "full"?
-- Are there other possible results that should be covered?

In other words, once we settle how to access the info, what does it look like? I'm trying to check the logic of the handler. Does it actually work on Linux now?
