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.
NOTICE: Handle components and cards with care. Do not touch the components or contacts on a card. Instead,
hold a card by its edges or by its metal mounting bracket. Hold a component such as a microprocessor 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. Some cables have connectors with locking tabs; before disconnecting this type of cable, press inward on
the locking tabs to release the connector. When connecting or disconnecting a cable, ensure that the connectors
are correctly oriented and aligned to avoid damage to the connector and/or the connector's pins.
NOTICE: To avoid damaging the computer, always perform the following steps before you begin working
inside the computer.
1. Ensure that the work surface is flat and clean to prevent scratching the computer cover.
2. Save any work in progress and exit all open programs.
3. Turn off the computer and all attached devices.
NOTE: Ensure that the computer is off and not in a power management mode. If you cannot shut down the
computer using the operating system, press and hold the power button for 4 seconds.
4. Disconnect the computer from the electrical outlet.
