Safety First—For You and Your Computer

The procedures in this section require that you open the cover and work inside your computer.

NOTICE: Do not attempt to service the computer yourself, except as explained in this guide and elsewhere in Dell documentation. Always follow installation and service instructions closely.

NOTICE: Before disconnecting a device from the computer or removing a component from the system board, verify that the standby power light on the system board has turned off. For the location of this light, see the system board.

Working inside your computer is safe—ifyou observe the following precautions.

CAUTION: FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE EQUIPMENT.

Before you start to work on the computer, perform the following steps in the sequence indicated:

1Turn off the computer and all devices.

2Touch an unpainted metal surface on the computer chassis, such as the metal around the card-slot openings at the back of your computer, before touching anything inside your computer.

3Disconnect the computer and devices from their electrical outlets. Doing so reduces the potential for personal injury or shock. Also disconnect any telephone or telecommunication lines from the computer.

In addition, take note of these safety guidelines when appropriate:

•When you disconnect a cable, pull on its connector or on its strain- relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make sure both connectors are correctly oriented and aligned.
