Check all cables to ensure that 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 disc media is correctly loaded
Always try to make detailed notes of your observations and keep them in a
permanent error log - this helps you to describe your problems to Technical
Support. In addition, if a problem recurs, the log you have made helps to
identify the problem faster.
Analyzing the problem
Sometimes the computer gives you clues that can help you identify why it
is malfunctioning. In view of this, keep the following questions in mind:
Which part of the computer is not operating properly - keyboard, HDD/
SSD, display panel, Touch Pad, Touch Pad control buttons - as each
device produces 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 Technical
Support.
Software The problems might be caused by your software
or disk. If you cannot load a software package,
the media might 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 usually
includes a problem-solving section or a summary
of error messages.
Next, check any error messages against the
operating system documentation.
