Before You Begin

Dell™ XPS™ 710 H2C Edition Service Manual

Getting Started

This chapter provides procedures for removing and installing the components in your computer. Unless otherwise noted, each

procedure assumes that a component can be replaced by performing the removal procedure in reverse order.

Recommended Tools

The procedures in this document may require one or more of the following tools:

Small flat-blade screwdriver

Phillips screwdriver

Flash BIOS update (see the Dell support website at support.dell.com)

Preparing to Work Inside Your Computer

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: To reduce the risk of fire, electric shock, or injury, do not overload an electrical outlet, power

strip, or convenience receptacle. The total ampere rating of all products plugged into an electrical outlet,

power strip, or other receptacle should not exceed 80 percent of the branch circuit rating.

CAUTION: Your computer is heavy and can be difficult to maneuver. Seek assistance before attempting to

lift, move, or tilt the computer and always lift correctly to avoid injury; avoid bending over while lifting.

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: To avoid electrostatic discharge and damage to internal components, ground yourself by using a wrist

grounding strap or by periodically touching an unpainted metal surface on the computer chassis.

NOTICE: Handle components and cards with care. Do not touch the components or contacts on a card. Instead, hold a

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

its pins.

NOTICE: When disconnecting a cable, pull on the cable's connector or its strain-relief loop, not on the cable itself.

Some cables have connectors with locking tabs; before disconnecting this type of cable, press inward on the locking

tabs to release the connector. When connecting or disconnecting a cable, ensure that the connectors are correctly

oriented and aligned to avoid damage to the connector and/or the connector's pins.

1. Ensure that the work surface is level and protected to prevent either the surface or the computer from being scratched.

NOTICE: To avoid losing data, save any work in progress and exit all open programs before turning off your computer.
