General problems Action
The computer does not
start when you press the
power switch. Verify that:
1. All cables are securely connected to the proper
connectors on the computer. For the location of
the connectors, see Chapter 8, “Installing external
options” on page 87.
2. The computer cover is properly installed.
If you cannot correct the problem, have the computer
serviced.
Problems such as a
broken cover lock or
indicator lights not
working. Have the computer serviced.
Intermittent problems Action
A problem occurs only
occasionally and is
difficult to repeat. Verify that:
1. All cables and cords are securely connected to the
rear of the computer and attached devices.
2. When the computer is turned on, the fan grill is not
blocked (there is air flow around the grill), and the
fans are working. If airflow is blocked or the fans
are not working, the computer might overheat.
3. If SCSI devices are installed, the last external
device in each SCSI chain is terminated correctly.
(See your SCSI documentation.)
If you cannot correct the problem, have the computer
serviced.
