Power Management
Each system incorporates power management features that lower power consumption when
there is no activity detected from the keyboard, mouse, diskette drive, CD-ROM reader, or
hard disk drive after a pre-defined period of time. As soon as activity is detected the system
resumes where it left off.
With Power Management enabled (shipped enabled), the system automatically activates the
power-saving features and enters a suspend mode whenever inactivity is sensed. The
suspend button quickly puts the system into a full power reduction mode of operation. This
is a convenient way to save power when away from the computer for a short period of time.
Press a key or move the mouse and the system returns to full power.
