Power Management
Chapter 2 Operating on Battery Power 41
"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 power management system. 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.
Standby Mode
The computer consumes very low power in Standby mode.
Data remains intact in the system memory until the battery
is drained.
There are four ways to enter Standby mode:
T Pressing the Standby hotkey Fn-F3
T If the waiting time specified by the Standby Timeout
value or the operating system elapses without any
system activity
T Closing the display cover
T When the computer is about to enter Hibernation mode
(e.g., during a battery low condition), but the
Hibernation file is invalid or not present
Note: If the computer does not enter Standby mode after
pressing the Standby hotkey, it means the operating
system will not allow the computer to enter the power-
saving mode.
