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.
WARNING: The heat sink may be very hot during normal operation. Be sure that it
has had sufficient time to cool before you touch it.
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: 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 your computer).
CAUTION: Do not perform the following steps unless you are familiar with hardware removal and replacement. Performing these steps incorrectly could damage your system board. For technical service information, see the Setup Guide.
CAUTION: To ensure maximum cooling for the graphics processor, do not touch the heat transfer areas on the graphics-card heat sink. The oils in your skin can reduce the heat transfer capability of the thermal grease.
In sequential order (indicated on the graphics-card heat sink), loosen the
four captive screws in descending order that secure the graphics-card heat
sink to the system board.
Lift the graphics-card heat sink away from the computer.
CAUTION: Before turning on the computer, replace all screws and ensure that no stray screws remain inside the computer. Failure to do so may result in damage to the computer.
Connect your computer and all attached devices to electrical outlets, and
turn them on.
