Power Management Modes
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 the period determined by the computer’s
HPM unit, the display shuts off until you press a key or
move the touchpad or external mouse.
"Automatic Dim" Feature
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 the period of time determined
by the HPM unit. 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.
Peripheral Standby Modes
The peripheral connections in your computer also power
down to save power if there is no activity within the period
of time specified by the computer’s HPM unit for these
devices. These include audio, serial ports, floppy drive and
parallel port.
Standby Mode
The computer consumes very low power in Standby mode.
Data remain intact in the system memory until the battery
is drained.
