NOTE: The images in this document may differ from your computer depending on the configuration you ordered.
1Save and close all open €les and exit all open applications.
2Shut down your computer.
The shut-down instruction varies depending on the operating system installed on your computer.
–Windows 10: Click Start → Power → Shut down.
–Windows 8.1: On the Start screen, click the power icon → Shut down.
–Windows 7: Click Start → Shut down.
NOTE: If you are using a different operating system, see the documentation of your operating system for shut-down instructions.
3Disconnect your computer and all attached devices from their electrical outlets.
4Disconnect all attached network devices and peripherals, such as keyboard, mouse, and monitor from your computer.
5Remove any media card and optical disc from your computer, if applicable.
6After the computer is unplugged, press and hold the power button for 5 seconds to ground the system board.
CAUTION: Place the computer on a flat, soft, and clean surface to avoid scratches on the display.
7 Place the computer face down.
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.
The procedures in this document may require the following tools:
