Front Panel
The computer's front panel contains the following indicators and controls (see Figure 1 for the desktop chassis or Figure 2 for the mini tower
chassis):
l
The power button controls the system's DC input power. When the system is turned off, pressing the power button turns the system on. When
the system is on, the power button operates as follows:
¡ In Windows NT, if the Dell AutoShutdown service is operational, the system performs an orderly operating system shutdown
before turning off.
If the Dell AutoShutdown service is not operational, the system turns off without writing unsaved data to the disk. This could result
in a loss of data.
¡ In Windows 2000, the system performs an orderly operating system shutdown before turning off. However, the power button can
be configured to put the computer in a low-power sleep state.
When the system is on, the power indicator LED displays a solid green. When the system is in a software-induced sleep
state, the power indicator displays a blinking green. When you press the power button to turn off the system, the power
indicator turns off; however, the power supply maintains a low-voltage (standby) current. To completely remove all power
from the system, unplug the DC power cable from its electrical outlet and disconnect the network and telephone cables.
For systems running Microsoft Windows NT with the Dell AutoShutdown service operational, pressing the power button causes the system to
perform an orderly operating system shutdown before turning off.
l The power indicator LED is green during normal system operation and blinks green when the computer is in sleep mode.
l The hard-disk drive access LED lights up when a hard-disk drive is in use.
l The diskette-drive access indicator lights up when the diskette drive is in use. (The drive access indicator for the tape drive is located on the
front of the drive.)
l The reset button reboots (restarts) the system without your having to turn the power off and then on again. Rebooting the system in this
manner reduces stress on system components.

NOTE: A Display Power Management Signaling (DPMS) monitor does not begin warming up until the computer to which it is
attached is turned on. Thus, some DPMS monitors may not display a video image until several seconds after you turn on the
computer.
NOTE: The power and hard-disk drive access LEDs are also used to display diagnostic codes .
