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.
