Use the following safety guidelines to help protect your computer from potential
damage and to 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.
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.
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 microprocessor by
its edges, not by its pins.
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.
1. Ensure that the work surface is flat and clean to prevent the computer cover
from being scratched.
2. Shut down the computer.
3. Ensure that the computer and any attached devices are turned off. If your
computer and attached devices did not automatically turn off when you shut
down your computer, press and hold the power button for 4 seconds.
4. If the computer is connected to a media base (docked), undock it. See the
documentation that came with your media base for instructions.
NOTICE: To disconnect a network cable, first unplug the cable from your
computer and then unplug it from the network wall jack.
5. Disconnect any telephone or telecommunication lines from the computer.
