/proc/acpi/event
All events are reported here and processed by the Powersave daemon
(powersaved). If no daemon accesses this file, events, such as a brief click on
the power button or closing the lid, can be read with cat /proc/acpi/event
(terminate with
/proc/acpi/dsdt and /proc/acpi/fadt
These files contain the ACPI tables DSDT (differentiated system description table)
and FADT (fixed ACPI description table). They can be read with acpidmp,
acpidisasm, and dmdecode. These programs and their documentation are lo-
cated in the package pmtools. For example, acpidmp DSDT | acpidisasm.
/proc/acpi/ac_adapter/AC/state
Shows whether the AC adapter is connected.
/proc/acpi/battery/BAT*/{alarm,info,state}
Detailed information about the battery state. The charge level is read by comparing
the last full capacity from info with the remaining capacity
from state. A more comfortable way to do this is to use one of the special pro-
grams introduced in
which a battery event (such as warning, low and critical) is triggered can be specified
in alarm.
/proc/acpi/button
This directory contains information about various switches, like the laptop lid and
buttons.
/proc/acpi/fan/FAN/state
Shows if the fan is currently active. Activate or deactivate the fan manually by
writing 0 (on) or 3 (off) into this file. However, both the ACPI code in the kernel
and the hardware (or the BIOS) overwrite this setting when the system gets too
warm.
/proc/acpi/processor/*
A separate subdirectory is kept for each CPU included in your system.
/proc/acpi/processor/*/info
Information about the energy saving options of the processor.
