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 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.
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).
CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from
the network device.
3 Disconnect all network cables from the computer.
4 Disconnect your computer and all attached devices from their electrical outlets.
5 Press and hold the power button while the computer is unplugged to ground the system board.
6 Remove the cover.
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.
1 Click or tap .
CAUTION: To connect a network cable, first plug the cable into the network device and then plug it into the
computer.
2 Connect any telephone or network cables to your computer.
3 Connect your computer and all attached devices to their electrical outlets.
4 Turn on your computer.
5 If required, verify that the computer works correctly by running Dell Diagnostics.
Recommended tools
The procedures in this document require the following tools:
Slow Blinking white light Computer is in sleep mode. • Press the power button to
bring the computer out of
the sleep mode.
• Ensure all power cables are
securely connected to the
