The Apm Interface - Targa Extender User Manual

The APM Interface

In addition to the power saving features built into the resident BIOS
System Configuration Utility, your Notebook computer also supports
the Intel-Microsoft Advanced Power Management.
APM is a cooperative interface that enhances the Notebook' s built-in
power management features by providing one of the most accurate
schemes for detecting true idle. This allows APM implementation to
put the CPU in a lower power state with no loss in user performance.
If APM is installed and properly configured, and power management
is enabled in the Setup program, APM functions in the following
manner:
•
Takes over power management from system BIOS
•
Constantly monitors all system activity to provide one of the most
accurate detection schemes for determining true idle under DOS,
Windows, and OS/2
•
Accounts for operating system inactivity and power demands
•
Accounts for application inactivity and power demands
•
Allows application programs, DOS, and BIOS to share power
management features to ensure more efficient use of power
•
Determines when power-saving features should be activated
•
Operates transparent to the user (behind the scenes)
While you are running an APM aware application, APM will detect
any system inactivity. If APM detects that either the operating system
or the application is waiting for input (or is in some other idle state);
APM will reduce the CPU to minimum speed. Once high speed is
required again, APM will increase the CPU to maximum speed. With
APM constantly monitoring all system activity, accounting for the
Notebook' s power consumption, and controlling all power-saving
features, you will realize significant additional power savings.
