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 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.
