Toshiba designed the T2150CD series computers 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.
Isolate the problem. Using the tools available to you, such as the troubleshooting tips in
this chapter and the diagnostic test program, TDIAGS, try to discover the specific
actions that caused the problem.
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 TSETUP program.
Check all cables. Are they correctly and firmly attached? Loose cables can cause signal
errors.
