Desktop Management

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.

3.2.3 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.

3.2.4 World Wide Web Site

When making the transition to new or revised operating systems, it is important to implement the

support software designed for that operating system. If you plan to run a version of Microsoft

Windows that is different from the version included with your computer, you must install

corresponding device drivers and utilities to ensure that all features are supported and

functioning properly.

HP has made the task of locating, accessing, evaluating, and installing the latest support software

easier. You can download the software from

http://www.hp.com/support

. The Web site contains

the latest device drivers, utilities, and flashable ROM images needed to run the latest Microsoft

Windows operating system on your HP computer.
