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 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.

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.

FILES
