of the computer and the setting for Advanced Power Management (APM) BIOS mode is ignored. Not
all operating systems support ACPI BIOS mode.

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 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).
