Microphone
The microphone that comes with the multimedia systems record voice and sound into computer
data files. The microphone jack is located on the back of the system.
KEYBOARD
The PS/2-style keyboard is standard equipment for the system. The keyboard provides a numeric
keypad, separate cursor control keys, and 12 function keys, capable of up to 48 functions. Status
lamps on the keyboard indicate: Num (Numeric) Lock, Caps (Capital) Lock, and Scroll Lock
key status. The keyboard's six-pin connector is plugged into the rear of the base unit. The PS/2-
style keyboard connector pin assignments are given in Appendix A, Connector Pin Assignments.
MOUSE
A PS/2-compatible mouse is standard equipment for the system. The mouse has a self-cleaning
mechanism that prevents a buildup of dust or lint around the mouse ball and tracking mechanism.
Periodically the mouse ball must be cleaned. See Section 4, Maintenance and Troubleshooting,
for information on cleaning the mouse.
POWER MANAGEMENT
Each computer system is Energy Star compliant and incorporates power management
features that lowers power consumption when there is no activity detected from the keyboard,
mouse, diskette drive, or hard disk drive after a predefined period of time. As soon as activity is
detected, the system resumes where it left off. To enable Power Management, see Section 2,
Setup.
If the computer is put into suspend mode by pressing the suspend button, the suspend
button must be pressed again to exit the suspend mode. System activity will not resume from sus-
pend mode.
