       /usr/sbin/laptop_mode - apply laptop mode settings


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


       This  manual  page documents briefly the /usr/sbin/laptop_mode command.
       laptop_mode is a  program  that  applies  the  settings  given  in  the
       /etc/laptop-mode/laptop-mode.conf  configuration  file. The primary use
       is to control the laptop mode feature included in  Linux  kernels  with
       versions  2.6.6  and  higher,  and  2.4.23  and  higher.   This feature
       increases 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.  In  addition  to
       supporting     the     Linux     kernel’s    laptop    mode    feature,
       /usr/sbin/laptop_mode also supports various power saving modules  which
       are   configured   through  configuration  files  in  the  /etc/laptop-
       mode/conf.d directory.

       It is not recommended to call /usr/sbin/laptop_mode directly  to  start
       or  stop  laptop  mode, except in hardware event handlers. To apply new
       configuration settings  from  laptop-mode.conf,  call  the  laptop-mode
       service init script with the reload parameter.


       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 :

       auto      Enable  or  disable  laptop  mode  based on the current power
                 state. Note that this will not do anything if the laptop-mode
                 service has not been started!
