AllOff Lite monitors the mouse, keyboard and CPU load and initiates computer power off if there has been no keyboard or mouse activity for 900 seconds and the average CPU load has been below 15% for over 60 seconds. AllOff Lite is part of the JSutils group of software utilities which have a theme of energy conservation. To find more energy and money saving ideas check out Practical Home Energy Saving. Uses of ALLoff Lite include unattended backup (shutting down the computer when the backup has completed) and shutting down a computer if the user forgets. It can be started via the Windows Task Scheduler, on start up or manually. AllOff Lite is a great little utility for saving energy by making sure a computer shuts down when not needed.

AllOff Lite supports Windows 2000, Windows XP, Windows 2003 and Windows Vista. The program needs administrator privileges to install. AllOff Lite operates by checking for keyboard and mouse activity plus the CPU load once a second. Each time there is activity the countdown timer is reset until the countdown time is reached and power off is initiated. Each time a key is pressed or the mouse is moved the activity will be displayed on the left of the main screen (when visible) with a 'K' indicating key presses and an 'M' indicating mouse movement. The average CPU load is also displayed. AllOff Lite runs in the System Tray (the program can be made visible by double clicking on the tray icon). Once power off is initiated AllOff Lite switches to visible 'run on top' and the About, Exit and Test buttons are disabled. power off can be cancelled by clicking the Cancel button which will put the program back in the System Tray unless the program was already visible. Program operation is inhibited while the About screen is open, this screen will automatically time out after 30 seconds if left open. CPU averaging works by adding the CPU load measured every second over an averaging period of 5 seconds and dividing it by the averaging period. This does mean that the average load can increase after the instantaneous CPU load has decreased due to previous values. This is especially noticeable with wide variations in CPU load. If the time the program has been active is less than the averaging period the time active is used as the averaging period.
