apm - query Advanced Power Management (APM) BIOS
apm [ -vVmsS ]
apm reads /proc/apm and presents the output in a human-
readable format. Since primarily battery status informa
tion 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.
-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 sus
pend 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.
