APM (1)
query Advanced Power Management (APM) BIOS
SYNOPSIS
DESCRIPTION
apm
reads
/proc/apm
and presents the output in a human-readable format. Since primarily
battery status information is provided, this command is most useful on
laptops with a compliant APM BIOS.
apm
also allows the machine to be put into standby or suspend mode.
OPTIONS
-V, --version
Print the
apm
program version and exit immediately.
-v, --verbose
Print information about the APM BIOS version and Linux APM driver version.
-m, --minutes
Print total minutes remaining instead of using an hh:mm format.
-s, --suspend
Put the machine into suspend mode if possible.
-S, --standby
Put the machine into standby mode if possible.
-i, --ignore
Tell the system to ignore system-generated APM suspend and standby events
when on AC power. This may be useful to users who have laptops and want
APM events when on battery power, but not when on AC power.
-n, --noignore
Tell the system
not
to ignore system-generated APM suspend and standby events
when on AC power. This is the default mode; this option is provided as a
way to undo a proir "apm -i" call.
BUGS
This program requires a post-1.3.57 kernel. This program will not work
with older kernels or with the APM patches, since the format for
/proc/apm
has changed radically.
