Principal Components and Features

Advanced Power Management (APM)

The Advanced Power Management (APM) is a standard, defined by Intel
and Microsoft, for a power-saving mode that is applicable under a wide
range of operating systems. The version APM 1.1 supports the following
modes: Fully-on, Standby, Suspend, and Off.
The Suspend mode, which also used to be known as Sleep, is now managed
at the operating system level only. There is no longer the inter-activity
between BIOS Setup and operating systems, and no longer a "sleep at" item
in the Setup menus. This is to avoid the BIOS from shutting down the
system at the wrong moment.
