Troubleshooting Tips
In general, troubleshooting involves an organized system of
approach to problem solving. Try to isolate the problem and
identify the defective device (hardware) or improper setting
(software). When you have a problem, you should do a
thorough visual inspection of the notebook computer.
•
If none of the indicators are lit and you cannot hear the
HDD spinning, then the notebook computer is probably
not receiving power.
•
Make sure the power cord is plugged in, and the AC
adapter is securely connected. The LEDs on the AC
adapter and the system should be on when connected
to a working AC source.
•
If you are using a power strip or surge protector, ensure
that these devices are turned on.
Often problems are caused by improperly connected cables.
•
If you are using peripherals such as the mouse or
keyboard, make sure they are properly connected to
their respective ports. Ensure that none of the
connectors’ pins are bent or broken.
•
Check all cables connected to the notebook computer.
If any are cut, frayed, or damaged in any way, replace
them right away. Never use a damaged cable. A
damaged cable is not only a fire hazard, it may also
cause a short circuit, resulting in irreparable damage to
the notebook computer.
•
Check all internal connections to ensure that they are
secure. Often problems can occur because a
connection is loose or backwards.
