CHAPTER 5: INSTALLING ADDITIONAL OR REPLACEMENT COMPONENTS
Before You Begin

your notebook. Unless otherwise noted, each procedure assumes that the following
conditions exist:
You have performed the steps in “Turning Off Your Notebook” and “Before •
Working Inside Your Notebook” in this section.
You have read the safety information that shipped with your notebook.
•
A component can be replaced or—if purchased separately—installed by •
performing the removal procedure in reverse order.
Turning Off Your Notebook
CAUTION: To avoid losing data, save and close all open files and exit all
open programs before you turn off your notebook.
Save and close all open files and exit all open programs. 1.
In Microsoft 2. ® Windows Vista ® , click Start (Windows Vista ® logo), click the
arrow, and then click Shut Down.
The notebook turns off after the operating system shutdown process finishes.
Ensure that the notebook and any attached devices are turned off. If your
3.
notebook and attached devices did not automatically turn off when you shut
down your operating system, press and hold the power button for at least
8 to 10 seconds until the notebook turns off.
Before Working Inside Your Notebook
Use the following safety guidelines to help protect your notebook from potential
damage and to help to ensure your own personal safety.
WARNING: Before working inside your notebook, read the safety information
“GENERAL AND ELECTRICAL SAFETY PRECAUTIONS“ on page 58 and
“DETAILED SAFETY, ENVIRONMENTAL, AND REGULATORY INFORMATION“ on
page 60. For additional safety best practices information, see the Regulatory
Compliance Homepage at www.dell.com/regulatory_compliance.
CAUTION: Handle components and cards with care. Do not touch the
components or contacts on a card. Hold a card by its edges. Hold a
component such as a processor by its edges, not by its pins.
CAUTION: Only a certified service technician should perform repairs on
your notebook. Damage due to servicing that is not authorized by Dell is
not covered by your warranty.
CAUTION: To avoid electrostatic discharge, ground yourself by using a
wrist grounding strap or by periodically touching an unpainted metal
surface (such as a connector on the back of the computer).
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; if you are disconnecting this type of cable, press in on the locking
tabs before you disconnect the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins. Also, before
you connect a cable, ensure that both connectors are correctly oriented
and aligned.
