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 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 the problem cannot be isolated and corrected, have the computer
serviced.
Keyboard, Mouse,
or Pointing-
Device Problems Action
All or some keys on
the keyboard do not
work. Verify that:
1. The computer and the monitor are turned on.
2. The keyboard cable is securely connected to the keyboard
connector on the computer. For the location of the keyboard
connector, see “Input/Output Device Connectors” on page 82.
If the problem cannot be isolated and corrected, have the keyboard
and computer serviced.
The mouse or
pointing device does
not work. Verify that:
1. The mouse or pointing-device cable is securely attached to the
proper connector on the computer. Depending on the type of
mouse you have, the mouse cable will connect to either the
mouse or serial connector. To find the mouse and serial
connectors, refer to “Input/Output Device Connectors” on
page 82.
2. The device drivers for the mouse are installed correctly.
If the problem cannot be isolated and corrected, have the computer
and the device serviced.
