The computer’s front panel contains the following indicators and controls (see
Figure 1-2):

The
power button
provides control of the system’s AC input power. The push-
button switch operates as follows:
— When the computer is turned off, pressing the button turns the computer on.
— When the computer is turned on, pressing the button turns the computer off.
However, a low-voltage (standby) current is maintained by the power supply.
To completely remove all power from the system, unplug the AC power
cable from its source.
For systems running Microsoft Windows 95, Windows 98, or 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.
(For more information, see “Dell AutoShutdown Service” in Chapter 2.)
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.

The
power indicator
light is green during normal system operation and amber
when the computer is in sleep mode.

The
hard-disk drive access indicator
lights up when a hard-disk drive is in use.

The
diskette-drive access indicator
lights up when the diskette drive is in use.

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.
