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.

Automatic configuration and power interface (ACPI) BIOS

Being an ACPI BIOS system, the operating system is allowed to control the power management features
of the computer and the setting 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.
• Serial Port A Ring Detect: With this feature set to Enabled and an external modem connected to serial
port (COM1), the computer will turn on automatically when a ring is detected on the modem.
• PCI Modem Ring Detect: With this feature set to Enabled, the computer will turn on automatically
when a ring is detected on the internal modem.
• PCI Wake Up: This feature allows PCI cards that support this capability to wake the system.
• 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 or a daily event.
• Wake on LAN: If the computer has a properly configured token-ring or Ethernet LAN adapter card that is
Wake on LAN-enabled and there is remote network management software, you can use the Wake on LAN
feature. When you set Wake on LAN to Enabled, the computer will turn on when it receives a specific
signal from another computer on the local area network (LAN)

Recovering software using the Rescue and Recovery program

When you install a new hard disk drive, you also need a set of Product Recovery discs. The set of Product
Recovery discs will enable the contents of the hard disk to be restored to the same state as when the
computer was originally shipped from the factory. For more information on recovering factory-installed
software, refer to "Recovering software" in the User Guide.
