Power Management

Overview
To conserve power, especially when using the battery, your computer uses the ACPI power management system. Power
management conserves power by controlling individual components of the computer (the monitor and hard disk drive) or the
whole system.

Advanced Configuration and Power Interface

The ACPI interface provides the computer with enhanced power saving techniques and gives the operating system (OS) direct
control over the power and thermal states of devices and processors. For example, it enables the OS to set devices into low-power
states based on user settings and information from applications. ACPI is fully supported in Windows XP.
OS Note
Power management functions will vary slightly depending on your operating system. For more information it is best to refer to the
user's manual of your operating system. (Note: All pictures used on the following pages are from the Windows XP OS.)
The Power Sources
The computer can be powered by either an AC/DC adapter or a battery pack.
AC/DC Adapter
Use only the AC/DC adapter that comes with your computer. The wrong type of AC/DC adapter will damage the computer and its
components.
1. Attach the AC/DC adapter to the DC-in jack at the rear of the computer.
2. Plug the AC power cord into an outlet, and then connect the AC power cord to the AC/DC adapter (see sidebar if you are
using the optional Port Replicator).
3. Raise the lid/LCD to a comfortable viewing angle.
4. Press the power button to turn "On".
Battery
The battery allows you to use your computer while you are on the road or when an electrical outlet is unavailable. Battery life varies
depending on the applications and the configuration you're using. To increase battery life, let the battery discharge completely
before recharging. Use the Battery Calibration Utility in the BIOS for the most efficient and straightforward method of battery
recharging (or see "How do I completely discharge the battery?"). We recommend that you do not remove the battery. For more
information on the battery, please refer to "Battery Information".
Turning on the Computer
Now you are ready to begin using your computer. To turn it on simply press the power button on the front panel. When the
computer is on, you can use the power button as a Stand by/Hibernate/Shutdown hot key button when it is pressed for less than 4
seconds (pressing and holding the power button for longer than this will shut the computer down). Use Power Options in the
Windows control panel to configure this feature.
Shutdown
Note that you should always shut your computer down by choosing the Turn Off Computer command from the Start menu in
Windows. This will help prevent hard disk or system problems.
Forced Off
If the system "hangs", and the Ctrl + Alt + Del key combination doesn't work, press the power button for 4 seconds, or longer, to
force the system to turn itself off.
