the suggested solutions and you still have a problem, make a list of what steps
you have taken to correct the problem and contact your dealer.
Successful troubleshooting is the result of careful observation, deductive
reasoning, and an organized approach to solving the problem.
The problems that you will encounter can be divided into two basic categories:
hardware problems and software problems. Hardware problems can be further
divided into electrical and mechanical problems. You will know you have a
hardware problem if the screen is dark, the computer cannot read the disk drives,
or you get an error message during the Power-On Self Test (POST).
Software errors can occur at several levels. The ROM BIOS and the operating
system can give you a large number of error messages. On top of this, each
application software package has its own set of error messages. It is important to
determine whether the software error message you are getting is from the
application or the operating system. Once you know this, you can look in the
respective manual for a solution to the problem.
Checking Cables and Connections
Start by performing a careful visual inspection of the exterior of the computer. If no
LEDs are illuminated, make sure that your computer and its peripherals are
getting power and communicating with each other properly.
To check the power cables and connections:
1. If you have been using battery power, connect the TransPort NX to an external
power source and make sure that the battery has a charge.
2. If you are using the TransPort NX with the AC adapter, check the power outlet,
the power cord, and any power switches that may affect your computer.
3. Check the wall outlet or power strip with an item that you know is functioning
properly. A lamp or radio is a convenient item for checking the power. You
may also need to check the fuses and breakers in your electric box.
4. If the outlet is controlled by a wall switch, make sure that the switch is on.
5. If the outlet is controlled by a dimmer switch, use a different outlet.
6. If your computer is plugged into a power strip with an On/Off switch, make sure
the switch is on.
7. With the computer’s power switched off, check all cable connections. If the
computer is connected to any peripheral devices, look for loose or
disconnected cables.
