Troubleshooting

Software	The problems may be caused by your software or
	diskette. If you cannot load a software package, the
	media (usually a diskette) 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 OS
	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.

Before using a peripheral device or application software that is not an authorized TOSHIBA part or product, make sure the device or software can be used with your computer. Use of incompatible devices may cause injury or may damage your computer.
