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 power source.

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.
