xternal Visual Inspection
The external visual inspection is a quick inspection of the exterior of the system
unit, the monitor, the keyboard, any peripherals, and cables. While performing
the visual inspection, make any necessary corrections. To perform the external
visual inspection, follow these steps:
1. Turn off the system unit, the monitor, and all peripherals.
2. Verify that all power cables are properly connected to the system unit,
the monitor and peripherals, and their power sources.
3. Verify that the keyboard and mouse interface cables are firmly
attached to the proper connectors on the back of the system unit.
For a PS/2-compatible mouse, the keyboard and mouse interface cable con-
nectors are identical except for their labels. If needed, see “System
Features” in Chapter 1.
For a serial mouse, the mouse interface cable must be firmly attached to one
of the serial port connectors, and its captive screws must be secure enough
to ensure a firm connection.
4. If present, verify that any network cables are attached properly.
5. Verify that any devices attached to the serial and parallel port connec-
tors are properly connected.
Each of the serial and parallel interface cables must be firmly attached to an
appropriate connector on the back of the system unit as well as to the inter-
face connector on the device. The captive screws that secure these
connectors at each end of the interface cable must be secure enough to
ensure a firm connection.
6. Verify that the video interface cable is firmly attached to the connector
on the back panel or to a video expansion card and to the connector on
the back of the monitor.
For proper connection of the video monitor, see the documentation for the
monitor.
7. Inspect all external monitor controls for any obvious damage or
improper settings.
For proper settings of the video monitor controls, see the documentation for
the monitor.
8. Inspect the keyboard to ensure that no keys are sticking.
If one or more keys are sticking, it may be necessary to replace the
keyboard.
