Troubleshooting

TOSHIBA have designed this tablet for durability, however, if 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. Make a screenshot of the current display.

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 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 detailed in this checklist shall provide easy fixes for issues which appear to be serious problems.

Make sure you turn on all peripheral devices before you turn on the tablet.

Before you attach an external device you should first turn the tablet off, then when you turn the tablet back on again it will recognize the new device.

Make sure all optional accessories are configured properly in the tablet's setup program and that all required driver software has been loaded (please refer to the documentation included with the optional accessories for further information on its installation and configuration).

Check all cables to ensure they are correctly and firmly attached to the tablet - loose cables can cause signal errors.
