The external visual inspection consists of a quick inspection of the exterior of
the computer, 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:
For a PS/2-compatible mouse, the keyboard and mouse interface cable
connectors 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.
Each of the serial, parallel, and USB interface cables must be firmly
attached to an appropriate 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.
For proper monitor connections, see the documentation for the monitor.
For proper settings of the monitor controls, see the documentation for the
monitor.
If one or more keys are sticking, it may be necessary to replace the
keyboard.
