You can easily correct certain computer problems by verifying the settings for system
setup program options. When you boot the computer, it compares the system
configuration information with the current hardware configuration. If the computer’s
hardware configuration doesn’t match the information recorded by the system setup
program options, an error message may appear on the display.
To fix this problem, correct the appropriate options in the system setup program. See
Appendix B, “Using the System Setup Program,” for detailed information about the
system setup program and its options.
If, after checking the setup options, you have not resolved the problem, see “Running
the Dell Diagnostics” found later in this chapter.
The keyboard status
indicators Press the <Num Lock> key, the <Caps Lock> key, and the <Scroll Lock> key to
toggle their respective status indicator. If the indicators do not light up, run the
PC-AT Compatible Keyboards device group in the Dell Diagnostics (for
instructions, see “Running the Dell Diagnostics” found later in this chapter).
The diskette-drive access
indicator The diskette-drive access indicator lights up when data is accessed on the
diskette drive. You can test this indicator by inserting a diskette into the drive,
typing

 at an MS-DOS prompt, and pressing <Enter>. If the
diskette-drive access indicator does not light up, see “Drives” found earlier in
this chapter.
The CD-ROM/hard-disk
drive access indicator The CD-ROM/hard-disk drive access indicator lights up when data is accessed
on the CD-ROM drive or the hard-disk drive. You can test this indicator by
typing

at an MS-DOS prompt and pressing <Enter>. If the CD-ROM/
hard-disk drive access indicator does not light up, see “Drives” found earlier in
this chapter.
A series of flashes See Appendix C, “Error Messages.”
An unfamiliar constant
scraping or grinding
sound when a drive is
accessed Make sure the sound is not caused by the application program that is running.
The sound could also be caused by a hardware malfunction. See Chapter 5,
“Getting Help,” for instructions on obtaining technical assistance from Dell.
The absence of a familiar
sound When you turn on the computer, you can hear the hard-disk drive spin up, and
the computer tries to access the boot files from the hard-disk drive or the
diskette drive. If your computer does not boot, call Dell for technical assistance.
(See Chapter 5, “Getting Help,” for instructions.) Other wise, see “Running the
Dell Diagnostics” found later in this chapter.
