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 Product Information Guide.
NOTICE: 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.
NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer.
Ensure that the work surface is flat and clean to prevent the computer cover from being
scratched.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network device.
Disconnect any telephone or network cables from the computer.
Disconnect your computer and all attached devices from their electrical outlets.
Close the display and turn the computer upside down on a flat work surface.
NOTICE: To avoid damaging the system board, you must remove the main battery before you service the computer.
