Linux / Unix Command: apm
Command Library


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.


-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 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.
-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 prior "apm -i" call.


xapm(1), apmd(8)

Important: Use the man command (% man) to see how a command is used on your particular computer.
