Before Working on Your Computer
Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own personal safety.
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: Some components become very hot during normal operation. Allow system components to cool before touching them.
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 the back of the computer.
CAUTION: When handling your computer, use care not to damage the wireless antenna.
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 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 surfaces from being scratched.
