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.
3. Disconnect your computer and all attached devices from their electrical outlets. 4. Disconnect all attached network devices and peripherals, such as keyboard, mouse, and monitor from your computer. CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device. 5.

● 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 CAUTION: 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.
