laptop-mode-tools 1.45-1ubuntu4 (i386 binary) in ubuntu intrepid

 Laptop mode is a Linux kernel feature that allows your laptop to save
 considerable power, by allowing the hard drive to spin down for longer
 periods of time. This package contains the userland scripts that are
 needed to enable laptop mode. It includes support for automatically
 enabling laptop mode when the computer is working on batteries. It also
 supports various other power management features, such as starting and
 stopping daemons depending on power mode, automatically hibernating if
 battery levels are too low, and adjusting terminal blanking and X11
 screen blanking.
