1-4 Dell Latitude XPi CD Service Manual
The portable computer has nine indicators: six on the display assembly’s indica-
tor panel and three on the keyboard assembly. Each of the six indicators on the
display assembly has an identical pair of LEDs: one is visible on the indicator
panel when the display is open, and the other is visible through an aperture on
the outside of the display assembly when the display is fully closed. The sub-
sections that follow describe the functions of the indicators.
Power/Suspend Indicator
The power/suspend indicator is a green LED. After the computer is turned on,
the power/suspend indicator lights up constantly to indicate that the computer is
receiving stable power. When the computer enters suspend mode, the indicator
blinks once approximately every 8 seconds.
Diskette-Drive Access Indicator
The diskette-drive access indicator is a green LED. The indicator lights when
data is being transferred to or from the diskette drive.
Hard-Disk/CD-ROM Drive Access Indicator
The hard-disk/CD-ROM drive access indicator is a green LED. The indicator
lights when data is being transferred to or from the hard-disk drive or the
CD-ROM.
PC Card Access Indicator
The PC Card access indicator is a green LED. The indicator lights when data is
being transferred to or from an installed PC Card (also known as a PCMCIA
card).
Low-Battery Indicator
The low-battery indicator is an amber LED. This indicator is used in conjunc-
tion with the speaker to indicate either of the following low-battery conditions:
• The first low-battery warning occurs when the main battery’s charge has
been depleted to 8 percent of its fully charged condition. The low-battery
indicator turns on and the speaker emits five beeps.
• The second and final low-battery warning occurs when the main battery’s
charge has been depleted to 3 percent of its fully charged condition. The
speaker beeps twice every 1 to 2 seconds for 15 seconds; then the system
does a suspend-to-disk operation automatically before shutting down.
Charging Indicator
The charging indicator is an amber LED. The indicator turns on when the main
battery begins charging and blinks to show the battery is fully charged.
