Checking 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 peripheral (such as a printer, keyboard, mouse, or other
external equipment).
NOTE: See "
" and "
" for the location of your
computer's external connections and switches.
Complete the following steps in the order indicated to check all the connections 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 AC power cables from their electrical outlets.
2. If your computer is connected to a power strip, turn the power strip off and then on again. If the problem
is not resolved, try another power strip or connect the system directly to an electrical outlet to see if the
original power strip is faulty.
3. Connect the system to a different electrical outlet.
If doing so corrects the problem, the original outlet is faulty.
4. Reconnect the system to an electrical outlet. Make sure that all connections fit tightly together, and turn
on the system.
5. If the problem is resolved, you have corrected a faulty connection.
6. If your monitor is not operating properly, see "
