| .SH "SYNOPSIS" |
| .B /usr/sbin/laptop_mode [ |
| .I cmd |
| .B ] [ force ] |
| .SH "DESCRIPTION" |
| This manual page documents briefly the |
| .I /usr/sbin/laptop_mode |
| command. laptop_mode is a program that applies the settings given in the |
| .I /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, |
| .I /usr/sbin/laptop_mode |
| also supports various power saving modules which are configured through |
| configuration files in the |
| .I /etc/laptop-mode/conf.d |
| directory. |
| .PP |
| It is not recommended to call |
| .I /usr/sbin/laptop_mode |
| directly to start or stop laptop mode, except in hardware event handlers. To |
| apply new configuration settings from \fIlaptop-mode.conf\fP, call the |
| laptop-mode service init script with the reload parameter. |
| .SH "COMMANDS" |
| Specify \fBforce\fP 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 |
| .I cmd |
| : |
| .IP "\fBauto\fP" 10 |
| 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! |
| .IP "\fBstatus\fP" 10 |
| Display a status report about everything that laptop_mode affects. |
