C
hecking Connections and
Switches
Improperly set switches and controls, and loose or
improperly connected cables, are the most likely source
of problems for your computer, monitor, or other periph-
eral (such as a printer, keyboard, mouse, or other external
equipment). A quick check of all the switches, controls,
and cable connections can easily solve these problems.
NOTE: See your system documentation for the location
of your computer’s external connections and switches.
Complete the following procedure to check all the con-
nections and switches:
1. Turn off the system, including any attached
peripherals (such as the monitor, keyboard,
printer, external drives, scanners, or plotters).
Disconnect all the alternating current (AC) power
cables from their power sources.
2. If your computer is connected to a power strip,
turn the power strip off and then on again.
Is the power strip getting power?
Yes. Go to step 5.
No. Go to step 3.
3. Plug the power strip into another electrical outlet.
Is the power strip getting power?
Yes. The original electrical outlet probably does not
function. Use a different electrical outlet.
No. Go to step 4.
4. Plug a lamp that you know works into the electri-
cal outlet.
Does the lamp get power?
Yes. The power strip is probably not functioning
properly. Get another power strip.
No. Go to step 5.
5. Reconnect the system to AC power.
Make sure that all connections fit tightly together.

Is the problem resolved?

problem.
