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 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 system enters a low-power mode.
