Display standby mode

Screen activity is determined by the keyboard, the built-in touchpad, and an external PS/2 pointing device. If these devices are idle for a specified period, the display shuts off until you press a key or move the touchpad or external mouse.

The computer has a unique "automatic dim" power-saving feature. When the computer is using AC power and you disconnect the AC adapter from the computer, it automatically dims the LCD backlight to save power. If you reconnect AC power to the computer, it automatically adjusts the LCD backlight to a brighter level.

Hard disk standby mode

The hard disk enters standby mode when there are no disk read/write operations within a specified period of time. In this state, the power supplied to the hard disk is reduced to a minimum. The hard disk returns to normal once the computer accesses it.

Setting power management schemes

Power management schemes allow you to specify the degree of power management to use on your computer at any particular time, simply by pressing the power management scheme toggle hot key Fn-F3.

Note: When an external keyboard is attached to the computer, this feature is disabled. The feature is also disabled if the operating system does not support it.
