	Troubleshooting
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.

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.
