laptop_mode(8) - Linux man page

Name

/usr/sbin/laptop_mode - start and stop laptop mode

Synopsis

/usr/sbin/laptop_mode [ cmd ] [ force ]

Description

This manual page documents briefly the /usr/sbin/laptop_mode command. /usr/sbin/laptop_mode is a program that enables and disables laptop mode. Laptop mode is a feature included in Linux kernels with versions 2.6.6 and higher, and 2.4.23 and higher. The intent of laptop mode is to increase battery life by letting your hard drive spin down. This is achieved by grouping disk write activity into "chunks" that are spaced at larger intervals than they normally would be.

Commands

Specify force as the second parameter to force laptop_mode to re-apply a state even if the computer is already in that state. These are the values that are allowed for cmd :
start
Enable laptop mode. Note: if the service /etc/init.d/laptop-mode has not been started, laptop mode will never be enabled.
stop
Disable laptop mode.
auto
Enable or disable laptop mode based on the current power state. This only works for ACPI or APM laptops. Note: if the service /etc/init.d/laptop-mode has not been started, laptop mode will never be enabled.
status
Display a status report about everything that laptop_mode affects.
