Working on Your Computer
Before Working Inside Your Computer
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 performed the steps in Working on Your Computer.
• 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: 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.
9
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.
To avoid damaging your computer, perform the following steps before you begin
working inside the computer.
1. Ensure that your work surface is flat and clean to prevent the computer
cover from being scratched.
2. Turn off your computer (see
Turning Off Your Computer
).
3. If the computer is connected to a docking device (docked) such as the
optional Media Base or Battery Slice, undock it.
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 network cables from the computer.
5. Disconnect your computer and all attached devices from their electrical
outlets.
6. Close the display and turn the computer upside-down on a flat work

8. Turn the computer top-side up.
9. Open the display.
10. Press the power button to ground the system board.
CAUTION: To guard against electrical shock, always unplug your computer from the
electrical outlet before opening the display.
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.
