CHAPTER 1: BEFORE YOU BEGIN

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

Ensure that the work surface is flat and clean.1. Ensure that sufficient space exists to support the computer with the side 2. panel(s) opened. Turn off your computer (see Turning Off Your Computer on page 3. 7) and all attached devices.

CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.

Disconnect all telephone or network cables from the computer.4. Disconnect your computer and all attached devices from their electrical 5. outlets. Disconnect all attached devices from your computer.6. Press the power button to ground the system board.7.

CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal components.

Before Working Inside Your Computer Use the following safety guidelines to help protect your computer from potential damage and to help to ensure your own personal safety.

WARNING: Before you begin any of the procedures in this section, follow the safety instructions that shipped with your computer. For additional safety best practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.

CAUTION: 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.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges. Hold a component such as a processor by its edges, not by its pins.

CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors 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.

If the release lever on the socket is not fully extended, move it to that 3. position. Align the pin-1 corners of the processor and socket. 4.

CAUTION: To avoid damage, ensure that the processor aligns properly with the socket, and do not use excessive force when you install the processor.

Set the processor lightly in the socket and ensure that the processor is 5. positioned correctly. When the processor is fully seated in the socket, close the processor cover. 6. Ensure that the tab on the processor cover is positioned underneath the center cover latch on the socket. Pivot the socket release lever back toward the socket, and snap it into place 7. to secure the processor.
