POWER MANAGEMENT

The Advanced Power Management (APM) program, located on the 82371EB PCI ISA IDE
Xcelerator (PIIX4E) chip, reduces system power consumption when there is no activity
detected from the keyboard, mouse, diskette drive, CD-ROM/DVD drive, or hard disk
drive after a predefined period of time. As soon as activity is detected, the system resumes
where it left off.
In the CMOS Setup utility, an inactivity timer is available for setting the length of time
before the sytem enter a low-power mode.
