Working on Your Computer

Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from potential damage and to help to ensure your 
personal safety. Unless otherwise noted, each procedure included in this document assumes that the following 
conditions exist:

You have performed the steps in Working on Your Computer.

You have read the safety information that shipped with your computer.

A component can be replaced or--if purchased separately--installed by performing the removal procedure in 

reverse order.

WARNING: Before working inside your computer, read the safety information that shipped with your computer. For 
additional safety best practices information, see the Regulatory Compliance Homepage at www.dell.com/
regulatory_compliance 

CAUTION: Many repairs may only be done by a certified service technician. You should only perform 
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or 
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your 
warranty. Read and follow the safety instructions that came with the product.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically 
touching an unpainted metal surface, such as a connector on the back of the computer.

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.

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.

NOTE: The color of your computer and certain components may appear differently than shown in this document.

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

1.

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

2.

Turn off your computer (see 

Turning Off Your Computer

).

3.

If the computer is connected to a docking device (docked) such as the optional Media Base or Battery Slice, 

undock it.

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

4.

Disconnect all network cables from the computer.

5.

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