Troubleshooting
This chapter describes locating and solving problems that you may
encounter while using your computer.
C HECKING C ABLES AND C ONNECTIONS
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 computer to
an external power source and make sure that the battery has
a charge.
2. If you are using the computer 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.
