							Chapter 6
Troubleshooting TOSHIBA has designed this computer for durability, however, shouldproblems occur you are able to use the procedures detailed in this chapter
to help determine the cause.
You should become familiar with this chapter as knowing what might go
wrong can help prevent problems from occurring in the first place.
Problem-solving process If you observe the following guidelines, resolving problems will be much
easier.
Stop immediately when you recognize a problem exists as taking
further action might result in data loss or damage, or you might destroy valuable problem-related information that can help solve theproblem.
Observe what is happening. Write down what the system is doing and
what actions you performed immediately before the problem occurred.
Make a screenshot of the current display.
Also be aware that the questions and procedures described in this chapter
are meant only as a guide, they are not definitive problem-solving techniques. In reality many problems can be solved simply, but a few mightrequire help from TOSHIBA Support. If you find you need to consult others,
be prepared to describe the problem in as much detail as possible.
Preliminary checklist You should always consider the simplest solution first. The items detailedin this checklist are easy to fix and yet can cause what appears to be aserious problem:
Make sure that you turn on all peripheral devices before you turn onthe computer - this includes your printer and any other external deviceyou are using.
Before you attach an external device you should first turn off the
computer, then when you turn the computer back on it recognizes the
new device.
Make sure that all optional accessories are configured properly in the
computer's setup program and that all required driver software has been loaded (refer to the documentation included with the optionalaccessories for further information on its installation and
configuration).

							Check all cables to ensure that they are correctly and firmly attachedto the computer - loose cables can cause signal errors.
Inspect all connecting cables for loose wires and all connectors forloose pins.
Check that your disc media is correctly loaded
Always try to make detailed notes of your observations and keep them in a permanent error log - this helps you to describe your problems to TOSHIBASupport. In addition, if a problem recurs, the log you have made helps to
identify the problem faster.
Analyzing the problem Sometimes the computer gives you clues that can help you identify why itis malfunctioning. In view of this, keep the following questions in mind:
Which part of the computer is not operating properly - keyboard, Hard
Disk Drive, display panel, Touch Pad, Touch Pad control buttons - as
each device produces different symptoms.
Check the options within the operating system to ensure that its
configuration is set properly.
What appears on the display? Does it display any messages or random characters? Make a screenshot of the current display and, ifpossible, look up the messages in the documentation included with the
computer, software, or operating system.
Check that all connecting cables are correctly and firmly attached as
loose cables can cause erroneous or intermittent signals.
Do any indicators light, if so, which ones, what color are they and do
they stay on or blink? Write down what you see.
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 TOSHIBA Support.
SoftwareThe problems might be caused by your software
or disk. If you cannot load a software package, the media might 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 usually
includes a problem-solving section or a summary
of error messages.
Next, check any error messages against the
operating system documentation.
