Software Updating and Management

3.1.1 Dual-State Power Button

With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP, the power
button can function either as an on/off switch or as a suspend button. The suspend feature does
not completely turn off power, but instead causes the computer to enter a low-power standby.
This allows you to quickly power down without closing applications and to quickly return to the
same operational state without any data loss.
To change the power button's configuration, complete the following steps:
1. Left click on the Start Button, then select Control Panel > Performance and
Maintenance > Power Options.
2. In the Power Options Properties, select the Advanced tab.
3. In the Power Button section, select the desired power button setting.
After configuring the power button to function as a suspend button, press the power button to put
the system in a very low power state (suspend). Press the button again to quickly bring the system
out of suspend to full power status. To completely turn off all power to the system, press and hold
the power button for four seconds.
Ä
CAUTION: Do not use the power button to turn off the computer unless the system is not responding;
turning off the power without operating system interaction could cause damage to or loss of data on the
hard drive.

3.1.2 Power Management

Power Management is a feature that saves energy by shutting down certain components of the
computer when they are not in use, saving energy without having to shut down the computer.
With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP, timeouts
(the period of inactivity allowed before shutting down these components) can be enabled,
customized, or disabled using the operating system.
1. In Windows XP, left click on the Start Button, then select Control Panel > Performance
and Maintenance > Power Options.
2. In the Power Options Properties, select the Power Schemes tab.
3. Select the desired power scheme settings.
Use Display Properties to establish, modify, or disable Power Management settings for the
monitor. To access Display Properties, right click on the Windows Desktop, then choose
Properties.
