Working on your computer
Safety instructions
Use the following safety guidelines to help protect your computer from potential damage and to help to ensure your personal safety.
Unless otherwise noted, each procedure included in this document assumes that the following conditions exist:
• You have read the safety information that shipped with your computer.
• A component can be replaced or--if purchased separately--installed by performing the removal procedure in reverse order.
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.
WARNING: Before working inside your computer, read the safety information that shipped with your computer. For
additional safety best practices information, see the Regulatory Compliance Homepage at www.dell.com/
regulatory_compliance
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and
simple repairs as authorized in your product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow
the safety instructions that came with the product.
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: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by
its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.
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.
NOTE: The color of your computer and certain components may appear differently than shown in this document.
Before working inside your computer
To avoid damaging your computer, perform the following steps before you begin working inside the computer.
1. Ensure that you follow the Safety instructions.

CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable
from the network device.
4. Disconnect all the network cables from the computer.
5. Disconnect your computer and all attached devices from the electrical outlets.
6. Press and hold the power button while the computer is unplugged to ground the system board.
7. Remove the cover.

dissipate static electricity, which could harm internal components.
Turning off your computer
After working inside your computer
After you complete any replacement procedure, ensure you connect any external devices, cards, and cables before turning on your
computer.

batteries designed for other Dell computers.
1. Connect any external devices, such as a port replicator or media base, and replace any cards, such as an ExpressCard.
2. Connect any telephone or network cables to your computer.
CAUTION: To connect a network cable, first plug the cable into the network device and then plug it into the
computer.
3. Replace the battery.
4. Replace the base cover.
5. Connect your computer and all attached devices to their electrical outlets.
