Steps1. Save and close all open files and exit all open applications.2. Shut down your computer. Click Start > Power > Shut down.NOTE: If you are using a different operating system, see the documentation of your operating system for shut-downinstructions.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 thecable from the network device.5. Remove any media card and optical disc from your computer, if applicable.Electrostatic discharge—ESD protectionESD is a major concern when you handle electronic components, especially sensitive components such as expansion cards,processors, memory DIMMs, and system boards. Very slight charges can damage circuits in ways that may not be obvious, suchas intermittent problems or a shortened product life span. As the industry pushes for lower power requirements and increaseddensity, ESD protection is an increasing concern.Due to the increased density of semiconductors used in recent Dell products, the sensitivity to static damage is now higher thanin previous Dell products. For this reason, some previously approved methods of handling parts are no longer applicable.Two recognized types of ESD damage are catastrophic and intermittent failures.● Catastrophic – Catastrophic failures represent approximately 20 percent of ESD-related failures. The damage causesan immediate and complete loss of device functionality. An example of catastrophic failure is a memory DIMM that hasreceived a static shock and immediately generates a "No POST/No Video" symptom with a beep code emitted for missing ornonfunctional memory.● Intermittent – Intermittent failures represent approximately 80 percent of ESD-related failures. The high rate ofintermittent failures means that most of the time when damage occurs, it is not immediately recognizable. The DIMMreceives a static shock, but the tracing is merely weakened and does not immediately produce outward symptoms related tothe damage. The weakened trace may take weeks or months to melt, and in the meantime may cause degradation of memoryintegrity, intermittent memory errors, etc.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 notprovide adequate protection. Touching the chassis before handling parts does not ensure adequate ESD protection on partswith 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.● When unpacking a static-sensitive component from its shipping carton, do not remove the component from the anti-staticpacking material until you are ready to install the component. Before unwrapping the anti-static packaging, ensure that youdischarge static electricity from your body.● Before transporting a static-sensitive component, place it in an anti-static container or packaging.ESD field service kitThe unmonitored Field Service kit is the most commonly used service kit. Each Field Service kit includes three main components:anti-static mat, wrist strap, and bonding wire.Components of an ESD field service kitThe components of an ESD field service kit are:● Anti-Static Mat – The anti-static mat is dissipative and parts can be placed on it during service procedures. When using ananti-static mat, your wrist strap should be snug and the bonding wire should be connected to the mat and to any bare metalon the system being worked on. Once deployed properly, service parts can be removed from the ESD bag and placed directlyon the mat. ESD-sensitive items are safe in your hand, on the ESD mat, in the system, or inside a bag.Working on your computer 7
