CHAPTER 1: BEFORE YOU BEGIN

Turning Off Your Computer

CAUTION: To avoid losing data, save and close all open files and exit all open programs before you turn off your computer.

Save and close all open files and exit all open programs.1.

Click 2. Start → Shut Down.

The computer turns off after the operating system shutdown process 3. finishes.

Ensure that the computer is turned off. If your computer did not 4.

automatically turn off when you shut down the operating system, press and hold the power button until the computer turns off.

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

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.

Turn off your computer (see "Turning Off Your Computer" on page 2. 7).

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.3.

Disconnect your computer and all attached devices from their electrical 4. outlets.

Disconnect all attached devices from your computer.5.

Press and eject any installed cards from the Media Card Reader.6.

Press and hold 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.

NOTE: For better access to components within your computer, lay your computer on its side.
