xternal Visual Inspection
The external visual inspection consists of a quick inspection of the exterior of
the computer, the monitor, the keyboard, any peripherals, and cables. While per-
forming the visual inspection, make any necessary corrections. To perform the
external visual inspection, follow these steps:
1. Turn off the computer, the monitor, and all peripherals.
2. Verify that all power cables are properly connected to the computer, the
monitor, and peripherals, and to their power sources.
3. Verify that the keyboard and mouse interface cables are firmly
attached to the proper connectors on the back of the computer.
For a PS/2-compatible mouse, the keyboard and mouse interface cable con-
nectors are identical except for their labels (see Figure 1-5).
For a serial mouse, the mouse interface cable must be attached to one of the
serial port connectors, and its captive screws must be secure enough to
ensure a firm connection.
4. 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 attached to an appro-
priate connector on the back of the computer as well as to the interface
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.
5. Verify that the video interface cable is firmly attached to the connector
on the I/O panel and to the connector on the back of the monitor.
For proper connection of the video interface cable, see the documentation
for the monitor.
6. 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.
7. 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.
8. Inspect the exterior of the computer, including all controls and indica-
tors, and all user-accessible data storage devices for any signs of
physical damage.
Does the inspection reveal any problems?
Yes . Proceed to the appropriate procedure in Chapter 4, “Removing and
Replacing Parts.”
No. Proceed to the next section, “Observing the Boot Routine.”
