Title:
on_ac_power says false, but real answer is true
Status in powermgmt-base package in Ubuntu:
Confirmed
Bug description:
On a Dell 7000 Micro (Intel 12700T), plugged into mains power,
on_ac_power reports false.
As the micro computer is plugged into mains power, I had expected it
instead to report true.
/sys/class/power_supply$ ls
ucsi-source-psy-USBC000:001
/sys/class/power_supply/ucsi-source-psy-USBC000:001$ cat type
USB
/sys/class/power_supply/ucsi-source-psy-USBC000:001$ cat online
0
The initial logic in /usr/bin/on_ac_power goes:
if [ -d /sys/class/power_supply/ ]; then
for FN in /sys/class/power_supply/*; do
if test -d "${FN}" && test -r "${FN}/type"; then
type="$(cat "${FN}/type")"
case "${type}" in
Mains|USB*|BrickID|Wireless)
if [ -r "${FN}/online" ]; then
online="$(cat "${FN}/online")"
[ "$online" = 1 ] && exit 0
[ "$online" = 0 ] && OFF_LINE_P=yes
fi;;
esac
fi
done
[ "${OFF_LINE_P}" = "yes" ] && exit 1
fi
Due the adapter being of type USB and the online status being 0,
OFF_LINE_P is set to "yes" and the script exits with status code 1.
