Study Notes
External Visual Inspection
- The external visual inspection involves a quick inspection of the exterior of the computer, monitor, keyboard, peripherals, and cables.
- Verify that all power cables are properly connected to the computer, monitor, and peripherals, and their power sources.
- Verify that the keyboard and mouse interface cables are firmly attached to the proper connectors on the back of the computer.
- Verify that network cables (if present) are properly attached.
- Verify that devices attached to the serial and parallel port connectors are properly connected.
- Verify that the video interface cable is firmly attached to the video connector on the back panel or to a video expansion card, and also to the connector on the back of the monitor.
- Inspect all external monitor controls for any obvious damage or improper settings.
- Inspect the keyboard to ensure that no keys are sticking.
- Inspect the exterior of the computer, including all controls and indicators, and all user-accessible data storage devices for any signs of physical damage.
Observing the Boot Routine
- Boot the system and observe the system for any indications of problems.
- Check the power supply fan; if it doesn't run normally, troubleshoot the system power supply.
- Watch the , , and indicators on the upper-right corner of the keyboard; they should flash momentarily and then the Num Lock indicator should light up and remain on (unless the Num Lock option is set to Off in the System Setup program).
- Observe the system for beep codes, system error messages, diskette-drive and hard-disk drive access indicators during the boot routine.
