Shutting Down 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 this procedure, read the safety instructions at the front of this document
(see page 11).
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 memory
module by its side edges, not by its connector edge.
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.
