Public bug reported:
laptop-mode will assume the system is a laptop if any battery is found.
I am running a desktop PC with a bluetooth battery powered Logitech K810
keyboard.
$ cat /sys/class/bluetooth/hci0:64/address
00:1f:20:91:df:35
$ ls /sys/class/power_supply
hid-00:1f:20:91:df:35-battery
$ cat /sys/class/power_supply/hid-00:1f:20:91:df:35-battery/type
Battery
$ cat /sys/class/power_supply/hid-00:1f:20:91:df:35-battery/scope
Device
The following laptop-detect code will assume the keyboard battery is an
ACPI battery:
# check for any ACPI batteries
/sbin/modprobe battery 2> /dev/null || true
if [ -d /sys/class/power_supply ]; then
for i in "`ls /sys/class/power_supply/*/ 2>/dev/null | grep -v hid`"; do
if grep -q Battery $i/type 2>/dev/null; then
$PRINTIT "We're a laptop (ACPI batteries found)" >&2
exit 0
fi
done
fi
Suggestion: filtering out /sys/class/power_supply/hid* before checking
battery type, or filter out scope = Device
