Before Working 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.
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 a connector on the back of the computer.
NOTICE: 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.
NOTICE: When disconnecting a cable, pull on the cable's connector or on its strain-relief loop, not on the cable itself.
For cable connectors with locking tabs, press inward on the locking tabs to release the connector. When connecting 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 flat and clean to prevent the computer cover from being scratched.
