IBM NetVista X40 User Manual page 105

See "Starting the diagnostic programs" on page 80 to test the system. If you have
run the diagnostic test programs or if running the tests does not reveal the
problem, call for service.
Look for the symptom in the left column of the chart. Instructions and probable
solutions to the problem are in the right column. If you have just added new
software or a new option and your system is not working, do the following before
using the troubleshooting charts:
v Remove the software or device that you just added.
v Run the diagnostic tests to determine if your system is running correctly.
v Reinstall the new software or new device.
Table 4. Troubleshooting charts
Device
CD-ROM drive
CD-ROM drive is not
recognized.
Diskette drive
Diskette drive in-use light stays
on, or the system bypasses the
diskette drive.
Expansion enclosure
The SCSI expansion enclosure
used to work, but does not
work now.
Other devices
Problems such as broken cover
locks or indicator lights not
working.
Intermittent problems
A problem occurs only
occasionally and is difficult to
detect.
Keyboard, mouse, or
pointing-device
All or some keys on the
keyboard do not work.
Suggested action
Verify that:
1. The primary IDE channel is enabled in the Configuration/Setup Utility
program.
2. All cables and jumpers are installed correctly.
3. The correct device driver is installed for the CD-ROM drive.
If there is a diskette in the drive, verify that:
1. The diskette drive is enabled in the Configuration/Setup Utility program.
2. The diskette is good and not damaged. (Try another diskette if you have one.)
3. The diskette contains the necessary files to start the system.
4. Your software program is OK.
If the diskette drive in-use light stays on, or the system continues to bypass the
diskette drive, call for service.
Verify that:
1. The cables for all external SCSI options are connected correctly.
2. The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.
3. Any external SCSI option is turned on. You must turn on an external SCSI
option before turning on the system.
For more information, see your SCSI and expansion enclosure documentation.
Call for service.
Verify that:
1. All cables and cords are connected securely to the rear of the system and
attached options.
2. When the system is turned on, air is flowing from the rear of the system at the
fan grille. If there is no air flow, the fan is not working. This causes the system
to overheat and shut down.
3. Ensure that the SCSI bus and devices are configured correctly and that the last
external device in each SCSI chain is terminated correctly.
If the items above are correct, call for service.
1. Make sure that the keyboard cable is properly connected to the system.
2. Make sure that the system and the monitor are turned on.
3. Try using another keyboard.
If the items above are correct, call for service.
