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.
NOTE: If you are using a different operating system, see the documentation of your operating system for shut-down instructions. 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.
The more difficult type of damage to recognize and troubleshoot is the intermittent (also called latent or "walking wounded") failure. Perform the following steps to prevent ESD damage: ● 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.
ESD protection summary It is recommended that all field service technicians use the traditional wired ESD grounding wrist strap and protective anti-static mat at all times when servicing Dell products. In addition, it is critical that technicians keep sensitive parts separate from all insulator parts while performing service and that they use anti-static bags for transporting sensitive components.
