ACPI ¶

To get battery/power monitoring on supported laptops you need to run the acpi deamon.

Add aux/acpi to /rc/bin/termrc.local.

E.g.

TIMESYNCARGS=(-ra1000000)
# start acpi
aux/acpi
# start cron
auth/cron

You cn now use stats -b to display a graph of the battery charge. The following script will display the battery status:

#!/bin/rc
# batt - display battery status
# usage: batt

rfork e

if(test -f /dev/battery){
    dt=`{awk '{print $1, $11, $12}' /dev/battery}
    echo Battery $dt(3) at $dt(1)^% dt(2) remaining
}
if not{
    echo batt: /dev/battery not found! >[1=2]
    exit nobattery
}
