Troubleshooting The Diskette Drive; Troubleshooting The Cd-Rom Drive - Dell Latitude CP Reference And Troubleshooting Manual

Troubleshooting the Diskette Drive

During the power-on self-test (POST), the computer
checks the diskette drive, comparing its characteristics
with the system configuration information. (The diskette-
drive access indicator blinks as the computer performs
this check.)
If a failure occurs with the drive, make a copy of the
Diagnostics Checklist found in Chapter 5 and fill it out as
you complete the following procedure.
1. Reboot the computer. Does the access indicator
blink during the boot routine (or does the activity
indicator light up on the external diskette drive)?
Yes. Go to step 3.
No. Go to step 2.
2. Remove and reinsert the diskette drive (or dis-
connect and reconnect the drive if used
externally). Reboot the computer. Does the drive
access indicator blink during the boot routine?
Yes. Go to step 3.
No. Go to step 6.
3. Does the computer display a drive error message?
Yes. See Table 3-2 for an explanation of the message,
and then go to step 4.
No. Go to step 6.
4. Insert a bootable 1.44-MB diskette into the drive,
and reboot the computer.
5. Does the drive access indicator blink during the
boot routine, and does the drive boot the operating
system?
Yes. The diskette drive problem has probably been
resolved. If you continue to experience trouble, call
Dell for technical assistance. (See Chapter 5, "Get-
ting Help," for instructions.)
No. Go to step 6.
6. Call Dell for technical assistance.
See Chapter 5, "Getting Help," for instructions.

Troubleshooting the CD-ROM Drive

During POST, the computer checks the CD-ROM drive,
comparing its characteristics with the system configura-
tion information. (The drive access indicator blinks as the
computer performs this check.)
NOTE: Check the config.sys and autoexec.bat files
before using the following procedure. If necessary, add
the following statement to the config.sys file:
device=c:\tsy\tsycdrom.sys. If necessary,
add the following statement to the autoexe.bat file:
c:\dos\mscdex.exe /d:tsycdl. Then save the
changes and reboot the computer. If the problem persists,
use the following troubleshooting procedure before call-
ing Dell.
If a failure occurs with the drive, make a copy of the
Diagnostics Checklist found in Chapter 5 and fill it out as
you complete the following procedure:
1. Turn off the computer, and then install the
CD-ROM drive in the modular bay. Reboot the
computer. Does the drive access indicator blink
during the boot routine.
Yes. Go to step 3.
No. Go to step 2.
2. Remove and reinsert the CD-ROM drive. Reboot
the computer. Does the drive access indicator
blink during the boot routine?
Yes. Go to step 3.
No. Go to step 7.
3. Remove the hard-disk drive, and boot the
computer. Does the drive access indicator blink
during the boot routine?
Yes. Go to step 4.
No. Go to step 7.
4. Reinstall the hard-disk drive. Then check the
CD-ROM configuration in the Settings folder. Is
the CD-ROM driver (tsycdrom.sys) installed?
Yes. Go to step 5.
No. Load the driver and return to step 1 to begin this
procedure again. (To load the driver, use the program
diskette sets you made when you first received your
Dell computer.)
