Hardware And System Checklist - Toshiba L450 User Manual

Do you hear any beeps? If so, how many, are they long or short, and
are they high pitched or low pitched? In addition, is the computer
making any unusual noises? Write down what you hear.
Record your observations so you can describe them in detail to your
reseller, dealer or service provider.

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.

The problems may be caused by your software or disk. If you
cannot load a software package, the media may be damaged
or the program might be corrupted - in these instances try
loading another copy of the software if possible.
If an error message appears while you are using a software
package you should refer to the documentation supplied with
it as this will usually include a problem solving section or a
summary of error messages.
Next, you should check any error messages against the
operating system documentation.
If you cannot find a software problem, you should then check
the setup and configuration of your hardware. First, run
through the items in the preliminary checklist as described
previously. Then, if you still cannot correct the problem, try to
identify the source - the next section provides checklists for
individual components and peripherals.
