Before Working Inside Your

Computer

CAUTION: To avoid damaging the components and cards,

handle them by their edges and avoid touching pins and

contacts.

NOTE: The images in this document may differ from your computer

depending on the configuration you ordered.

Shut down.

NOTE: If you are using a different operating system, see the

documentation of your operating system for shut-down instructions.

3 Disconnect your computer and all attached devices from their electrical

outlets.

4 Disconnect all cables such as telephone cables, network cables and so on,

from your computer.

5 Disconnect all attached devices and peripherals, such as keyboard, mouse,

monitor, and so 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, make sure 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,

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, make

sure 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.
