on, from your computer.

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 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 dell.com/regulatory_compliance.

CAUTION: Before touching anything inside your computer, ground

yourself by touching an unpainted metal surface. 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: To disconnect a network cable, first unplug the cable from

your computer and then unplug the cable from the network device.

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

reader.
