Shutting Down Your Computer
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 at the
front of this document
(see page 9).
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 processor
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.
