Troubleshooting
TOSHIBA have designed this computer for durability, however, should
problems occur you are able to use the procedures detailed in this chapter
to help determine the cause.
All users 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
Resolving problems will be much easier if you observe the following
guidelines:
■ Stop immediately when you recognize a problem exists as taking further
action may result in data loss or damage, or you may destroy valuable
problem related information that can help solve the problem.
■ Observe what is happening - write down what the system is doing and
what actions you performed immediately before the problem occurred.
If you have a printer attached, print a copy of the screen using the
computer's PRTSC key.
Please 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 may
require help from your reseller, dealer or service provider - 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 detailed in
this checklist are easy to fix and yet can cause what appears to be a
serious problem:
■ Make sure you turn on all peripheral devices before you turn on the
computer - this includes your printer and any other external device you
are using.
■ Before you attach an external device you should first turn the computer
off, then when you turn the computer back on again it will recognize the
new device.
