Power management

Power management reduces the power consumption of certain components of the computer such as the
system power supply, processor, hard disk drives, and some monitors.

Advanced configuration and power interface (ACPI) BIOS

As this computer has an ACPI BIOS system, the operating system is allowed to control the power
management features of the computer and the settings for Advanced Power Management (APM) BIOS mode
is ignored. Not all operating systems support ACPI BIOS mode.

Automatic Power-On features

The Automatic Power-On features within the Power Management menu allow you to enable and disable
features that turn on the computer automatically.

• Wake Up on Alarm: You can specify a date and time at which the computer will be turned on automatically.

This can be either a single event , a daily event or a weekly event.

• Wake Up on LAN: This feature allows LAN adapter card to wake the System.

POST error codes

Each time you turn the computer on, it performs a series of tests to check that the system is operating
correctly and that certain options are set. This series of tests is called the

Power-On Self-Test

, or

POST

.

POST does the following:

• Checks some basic system-board operations

• Checks that the memory is working correctly

• Starts video operations

• Verifies that the boot drive is working
