Novell LINUX ENTERPRISE SERVER 10 SP2 - INSTALLATION AND ADMINISTRATION Installation Manual page 530

acts as a front-end for the Powersave daemon. The following describes the most impor-
tant files:
/proc/acpi/info
General information about ACPI.
/proc/acpi/alarm
Here, specify when the system should wake from a sleep state. Currently, this feature
is not fully supported.
/proc/acpi/sleep
Provides information about possible sleep states.
/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 Ctrl + C ).
/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 Section 28.3.3, "ACPI Tools" (page 516). The charge level at
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.
