Check all cables to ensure they are correctly and firmly attached to the
computer - loose cables can cause signal errors.
Inspect all connecting cables for loose wires and all connectors for
loose pins.
Check that your CD/DVD/BD media is correctly loaded
Always try to make detailed notes of your observations and keep them in a
permanent error log - this will help you to describe your problems to
TOSHIBA Support. In addition, if a problem recurs, the log you have made
will help to identify the problem faster.
Analyzing the problem
Sometimes the computer will give you clues that can help you identify why
it is malfunctioning. In view of this you should 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 will produce 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, if
possible, 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.
Software The problems may be caused by your software
or disk. If you cannot load a software package,
the media may 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 will usually
include a problem solving section or a summary
of error messages.
Next, you should check any error messages
against the operating system documentation.
