Troubleshooting

TOSHIBA designed the computer for durability. However, should problems occur,
following the procedures in this chapter can help to determine the cause.

All readers should become familiar with this chapter. Knowing what might go wrong
can help prevent problems from occurring.

Problem solving process

Resolving problems will be much easier if you observe the following guidelines:

Stop immediately when you recognize a problem exists. Further action may
result in data loss or damage. 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 PrtSc SysReq.

The questions and procedures offered in this chapter are meant as a guide, they are
not definitive problem solving techniques. Many problems can be solved simply,
but a few may require help from your dealer. If you find you need to consult your
dealer or others, be prepared to describe the problem in as much detail as possible.

Preliminary checklist

Consider the simplest solution first. The items 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, turn the computer off. When you turn the
computer back on it recognizes the new device.

Make sure all options are set properly in the setup program.

Check all cables. Are they correctly and firmly attached? Loose cables can
cause signal errors.

Inspect all connecting cables for loose wires and all connectors for loose pins.
