following conditions exist:

lYou have performed the steps in Turning Off Your Computer and Safety Instructions.

lYou have read the safety information that ships with your computer.

lA component can be replaced or—if purchased separately—installed by performing the removal procedure in reverse order.

2. Ensure that the computer and all attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut

down your operating system, press and hold the power button for about 4 seconds to turn them off.

Safety Instructions

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



1. Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.



2. Turn off your computer (see 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.

WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best

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 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.
