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 “Desktop model connections”
on page 12 or “Tower model connections” on
page 13.
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 detect. Verify that:
1. All cables and cords are securely connected to the
rear of the computer and to 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.
