Working inside your computer
Safety instructions
Use the following safety guidelines to protect your computer from potential damage and to ensure your personal safety. Unless
otherwise noted, each procedure in this document assumes that you have read the safety information that shipped with your
computer.
WARNING: Before working inside your computer, read the safety information that is shipped with your
computer. For more safety best practices, see Dell Regulatory Compliance Home Page.
WARNING: Disconnect your computer from 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 your
computer to an electrical outlet.
CAUTION: To avoid damaging the computer, ensure that the work surface is flat, dry, and clean.
CAUTION: You should only perform troubleshooting and repairs as authorized or directed by the Dell technical
support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. See the
safety instructions that are shipped with the product or at Dell Regulatory Compliance Home Page.
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: To avoid damaging the components and cards, handle them by their edges, and avoid touching the
pins and the contacts.
CAUTION: When you disconnect a cable, pull it by its connector or its pull tab, not the cable itself. Some cables
have connectors with locking tabs or thumbscrews that you must disengage before disconnecting the cable.
When disconnecting cables, keep them evenly aligned to avoid bending the connector pins. When connecting
cables, ensure that the connector on the cable is correctly oriented and aligned with the port.
CAUTION: Press and eject any installed card from the media-card reader.
CAUTION: Exercise caution when handling rechargeable Li-ion batteries in laptops. Swollen batteries should not
be used and should be replaced and disposed properly.
