Troubleshooting
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
device - this includes any other external device you are using.
■
Before you attach an external device you should first turn the device off,
then when you turn the device back on again it will recognize the new
device.
■
Make sure all optional accessories are configured properly in the
device’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
device - loose cables can cause signal errors.
■
Inspect all connecting cables for loose wires and all connectors for
loose pins.
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 your
reseller, dealer or service provider. In addition, if a problem recurs, the log
you have made will help to identify the problem faster.
Analyzing the problem
Sometimes the device 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 device is not operating properly - keyboard, 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? If possible, look up the messages in the documentation
included with the device, 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 device making any
unusual noises? Write down what you hear.
Record your observations so you can describe them in detail to your
reseller, dealer or service provider.
