Safety instructions

Use the following safety guidelines to protect your computer from potential damage

and ensure your personal safety.

WARNING: Before working inside your computer, read the safety

information that shipped with your computer. For more safety best

practices, see the Regulatory Compliance home page at www.dell.com/

regulatory_compliance.

WARNING: Disconnect all power sources before opening the computer

cover or panels. After you finish working inside the computer, replace all

covers, panels, and screws before connecting to the electrical outlet.

CAUTION: To avoid damaging the computer, ensure that the work surface

is flat and clean.

CAUTION: To avoid damaging the components and cards, handle them by

their edges, and avoid touching pins and contacts.

CAUTION: You should only perform troubleshooting and repairs as

authorized or directed by the Dell technical assistance team. Damage due to

servicing that is not authorized by Dell is not covered by your warranty. See

the safety instructions that shipped with the product or at www.dell.com/

regulatory_compliance.

CAUTION: Before touching anything inside your computer, ground yourself

by touching an unpainted metal surface, such as the metal at the back of

the computer. While you work, periodically touch an unpainted metal

surface to dissipate static electricity, which could harm internal

components.

CAUTION: When you disconnect a cable, pull on its connector or on its pull

tab, not on the cable itself. Some cables have connectors with locking tabs

or thumb-screws that you must disengage before disconnecting the cable.

When disconnecting cables, keep them evenly aligned to avoid bending any

connector pins. When connecting cables, ensure that the ports and

connectors are correctly oriented and aligned.

CAUTION: Press and eject any installed card from the media-card reader.
