Analyzing the problemSometimes the system gives clues that can help you identify why it is malfunctioning. Keep the following questions in mind:
■Which part of the system is not operating properly: keyboard, hard disk drive, optical media drive, display. Each device produces different symptoms.
■Is the operating system configuration set properly? Check the configuration options.
■What appears on the display screen? Does it display any messages or random characters? Print a copy of the screen if you have a printer attached. Look up the messages in the software and operating system documentation. Check that all connecting cables are correctly and firmly attached. Loose cables can cause erroneous or intermittent signals.
■Do any indicators light? Which ones? What color are they? Do they stay on or blink? Write down what you see.
■Do you hear any beeps? How many? Are they long or short? Are they high pitched or low? Is the computer making any unusual noises? Write down what you hear.
Record your observations so you can describe them to your dealer.
Software | The problems may be caused by your software or |
| disc. If you cannot load a software package, the |
| media may be damaged or the program might be |
| corrupted. Try loading another copy of the |
| software. |
| If an error message appears while you are using a |
| software package, check the software |
| documentation. These documents usually include |
| a problem solving section or a summary of error |
| messages. |
| Next, check any error messages in the operating |
| system documentation. |
Hardware | If you cannot find a software problem, check your |
| hardware. |
| First run through the items in the preliminary |
| checklist above. If you still cannot correct the |
| problem, try to identify the source. The next |
| section provides checklists for individual |
| components and peripherals. |
