1 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 included 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 the Regulatory Compliance home page at www.dell.
5. Remove any media card and optical disc from your computer, if applicable. 6. Place the computer face down. CAUTION: Place the computer on a flat, soft, and clean surface to avoid scratches on the display. Safety precautions The safety precautions chapter details the primary steps to be taken before performing any disassembly instructions.
● Use a wired ESD wrist strap that is properly grounded. The use of wireless anti-static straps is no longer allowed; they do not provide adequate protection. Touching the chassis before handling parts does not ensure adequate ESD protection on parts with increased sensitivity to ESD damage. ● Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads.
Transporting sensitive components When transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in anti-static bags for safe transport. After working inside your computer About this task NOTE: Leaving stray or loose screws inside your computer may severely damage your computer. Steps 1. Replace all screws and ensure that no stray screws remain inside your computer. 2.
