Overview 1-5
The system has the following devices, controls, and lamps at the front of the system (see the
above figures for device, control, and lamp locations).
! Power/sleep button — press this button to turn on system power. To turn off power, close
all applications, shut down Windows®; Windows 98 and Windows 2000 automatically
power down the system. For Windows NT®, close all applications, shut down Windows NT,
and press in the power button until the system powers down (approximately four seconds).
Press and immediately release the power button to suspend system operation and go into the
power saving mode. If a VESA-compliant monitor is in use, the monitor also goes into a
power-saving mode.
Press any key or move the mouse to exit the power saving mode and resume system
operation.
! Power/sleep lamp — indicates if system power is on or off. Also indicates if the system is
operating in a power saving mode.
A steady green lamp indicates that power is on. An amber lamp and a blank screen indicates
that the system is in a sleep mode with full power reduction.
! Hard drive lamp — when blinking, indicates that the hard drive is active. A blinking lamp
indicates that the hard drive is reading or writing data.
! CD-ROM drive — load and start programs from a compact disc (CD) and to play audio
CDs. Controls and indicators include a CD tray open button, drive activity lamp, and
emergency tray open feature. Controls for an optional DVD-ROM drive are similar.
! DVD-ROM drive — DVD-ROM drives offer many improvements over the standard
CD-ROM technology, including superior video and audio playback, faster data access, and
greater storage capacities.
The DVD-ROM drive uses DVD technology to read DVD discs as well as standard audio
and video CDs.
! CD-RW drive — use the drive to read and write data on a CD-RW disc many times, just
like you would with a diskette, Zip disk, or hard drive.
! Zip drive — use the Zip drive with 3 1/2-inch Zip disks to back up work, archive old files,
and transport work. The Zip drive supports both 250-MB and 100-MB Zip disks.
! Diskette drive — copy data files to and from a diskette or use as a bootable drive for
loading and starting programs from a diskette. Controls and indicators include a diskette
eject button and drive activity lamp.
! USB port — use this port to connect up to 127 universal serial bus (USB) devices without
opening the system. A second port is on the rear of the system.
