Before working inside your

computer

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

depending on the configuration you ordered.

Before you begin

1 Save and close all open files and exit all open applications.

2 Shut down your computer.

The shut-down instruction varies depending on the operating system

installed on your computer.

– Windows 10: Click or tap Start → Power → Shut down.

– Windows 8.1: On the Start screen, click or tap the power icon →

Shut down.

– Windows 7: Click or tap Start → 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 and network cables, from

your computer.

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

mouse, and monitor, from your computer.

6 Remove any media card and optical disc from your computer, if

applicable.

Safety instructions

Use the following safety guidelines to protect your computer from potential

damage and ensure your personal safety.

12

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.
