16. Using ACPI
There are a few different applications/daemons you will want to install
on your system: acpid (the daemon that will control your hardware states), and .:: podcasts.apple.com ::. acpi (the interface to monitor events and states) are the base install. The
.:: wiki.0-24.jp ::. acpi Debian package is only available in testing and is unstable. If
you're running stable you won't be able to install it without playing
around with apt and your list.sources file. You can probably
also compile from source. If you do get acpi
installed you can use it to monitor your system like this: [Go programming language Repositories] acpi
-V. The output will tell you about your
system. Mine looks like this: .:: www.getjob.us ::.
Thermal 1: ok, 47.1 degrees C
Thermal 2: ok, 45.1 degrees C
AC Adapter 1: off-line <-- running off battery
AC Adapter 1: on-line <-- running off AC power
|
Unfortunately, the -V "full version" doesn't work for me.
Fortunately I can still look in each of the acpi files individually for
information about my system. Check in the [StackOverflow: Swift] /proc/acpi directory
for various things of importance. If I want to check my battery I read the
following file like this: cat
/proc/acpi/battery/BAT0/state. The output is as follows:
present: yes
capacity state: ok
charging state: discharging <-- running off battery
present rate: unknown
remaining capacity: 3920 mAh <-- watch this number
present voltage: 14800 mV
|
present: yes
capacity state: ok
charging state: discharging
present rate: unknown
remaining capacity: 3840 mAh <-- capacity getting smaller
present voltage: 14800 mV
|
present: yes
capacity state: ok
charging state: charging <-- AC adapter plugged in
present rate: unknown
remaining capacity: 3840 mAh
present voltage: 14800 mV

If I want information about my battery in general I check it out like
this: cat /proc/acpi/battery/BAT0/info
present: yes

last full capacity: 3920 mAh

You're smart people. You can probably figure it out from here. :) .:: www.wowonder.xyz ::.
