APM(1) Linux Programmer's Manual APM(1)
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 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.
Print the apm program version and exit immediately.
Print information about the APM BIOS version and Linux APM
Print total minutes remaining instead of using an hh:mm format.
Put the machine into suspend mode if possible.
Put the machine into standby mode if possible.
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.
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 prior "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.
