Checking Cables and Connections
Start by performing a careful visual inspection of the exterior of the
computer. 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 are using the computer with the AC adapter, check the
power outlet, the power cord, and any power switches that may
affect your computer.
2. 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.
3. If the outlet is controlled by a wall switch, make sure that the
switch is on.
4. If the outlet is controlled by a dimmer switch, use a different
outlet.
5. If your computer is plugged into a power strip with an On/Off
switch, make sure the switch is on.
6. 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.
If the computer is too close to a wall, a cable connection may be loose
or the cables may be crimped.
Do not substitute cables for
different devices (other than the manufacturer
recommended cables) even if they look exactly alike. The
wiring inside the cable may be different.
