Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own

personal safety.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the

Product Information Guide.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card.

Hold a card by its edges or by its metal mounting bracket. Hold a component such as a processor by its
edges, not by its pins.

NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is

not authorized by Dell is not covered by your warranty.

NOTICE: 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 you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any
connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.

NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer.

1. Follow the steps in Turning Off Your Computer

NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the

network port or device.

2. Disconnect any telephone or network cables from the computer.

3. Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to

ground the system board.

.

CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before
