Preparing to Work Inside the Computer

CAUTION: Before you perform any of the procedures in this section, follow the safety instructions in the Product Information Guide.

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, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such as the back panel) on the computer.
