APM(1) Linux Programmer's Manual APM(1)
NAME
apm - query Advanced Power Management (APM) BIOS
SYNOPSIS
apm [ -vVmsS ]
DESCRIPTION
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.
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.
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.
