damage and to help to ensure your personal safety. Unless otherwise noted, each
procedure included in this document assumes that the following conditions exist:
You have performed the steps in Working on Your Computer.
You have read the safety information that shipped with your computer.
A component can be replaced or--if purchased separately--installed by
performing the removal procedure in reverse order.
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 certified 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

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: 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.
