Hard disk drive problems
Symptom
Not all drives are recognized by
the hard disk drive diagnostic
test (the Fixed Disk test).
The computer stops responding
during hard disk drive diagnostic
test.
IEEE 1394 (firewire) port problems
Symptom
An IEEE 1394 device does not
work.
Intermittent problems
Symptom
A problem occurs only
occasionally and is difficult to
detect.
Keyboard, mouse, or pointing-device problems
Symptom
All or some keys on the
keyboard do not work.
The mouse or pointing device
does not work.
FRU/action
1. Remove the first drive not recognized and try the hard disk drive
diagnostic test again.
2. If the remaining drives are recognized, replace the drive that you removed with
a new one.
1. Remove the hard disk drive being tested when the computer stopped
responding and try the diagnostic test again.
2. If the hard disk drive diagnostic test runs successfully, replace the drive you
removed with a new one.
FRU/action
Make sure that:
v The correct IEEE 1394 device driver is installed.
v The operating system supports IEEE 1394 devices.
FRU/action
1. Make sure that:
v All cables and cords are connected securely to the rear of the computer and
attached options.
v When the computer is turned on, air is flowing from the rear of the computer
at the fan grille. If there is no airflow, the fan is not working. This causes the
computer to overheat and shut down.
v The SCSI bus and devices are configured correctly and the last external
device in each SCSI chain is terminated correctly.
2. Check the system-error log.
FRU/action
1. Make sure that:
v The keyboard cable is securely connected to the computer, and the
keyboard and mouse cables are not reversed.
v The computer and the monitor are turned on.
2. Keyboard.
3. System board.
1. Make sure that:
v The mouse or pointing-device cable is securely connected to the computer,
and the keyboard and mouse cables are not reversed.
v The mouse device drivers are installed correctly.
v Both the computer and the monitor are turned on.
2. Mouse or pointing device.
3. System board.
