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
System Information Guide.
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.
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: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some
cables have a connector 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.

1. Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.
2. Turn off your computer.

docking device for instructions.

network wall jack.
4. Disconnect any telephone or telecommunication lines from the computer.
5. Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to
ground the system board.
NOTICE: To connect a network cable, first plug the cable into the network wall jack and then plug it into the computer.

.
7. Close the display and turn the computer upside down on a flat work surface.
