NOTE: Fixed-voltage power supplies and auto-select power supplies do not require a voltage selection switch. Your power supply may not have this switch. Check the regulatory label on the outside of the computer for your power supply type.

Also be sure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.

•To avoid shorting out your computer when disconnecting a network cable, first unplug the cable from the network adapter on the back of your computer, and then from the network jack. When reconnecting a network cable to your computer, first plug the cable into the network jack, and then into the network adapter.

•To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before disconnecting or connecting a non-USB device from the computer.

•To help prevent electric shock, plug the computer and device power cables into properly grounded power sources. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a three-wire cable with properly grounded plugs.
