About this task
WARNING: Disconnect all power sources before opening the computer cover or panels. After you nish working inside the
computer, replace all covers, panels, and screws before connecting to the power source.
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
CAUTION: Many repairs may only be done by a certied service technician. You should only perform troubleshooting and simple
repairs as authorized in your product documentation, or as directed by the online or telephone service and support team.
Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions
that came with the product.
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an
unpainted metal surface at the same time as touching a connector on the back of the computer.
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 you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have
connectors with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the
cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a
cable, ensure that both connectors are correctly oriented and aligned.
NOTE: The color of your computer and certain components may appear dierently than shown in this document.
