/usr/sbin/laptop_mode - start and stop laptop mode
/usr/sbin/laptop_mode [ cmd ] [ force ]
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.
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
