After working inside your computer CAUTION: Leaving stray or loose screws inside your computer may severely damage your computer. Replace all screws and ensure that no stray screws remain inside your computer. Connect any external devices, peripherals, or cables you removed before working on your computer. Replace any media cards, discs, or any other parts that you removed before working on your computer.
Due to the increased density of semiconductors used in recent Dell products, the sensitivity to static damage is now higher than in previous Dell products. For this reason, some previously approved methods of handling parts are no longer applicable.
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.
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. Lifting equipment Adhere to the following guidelines when lifting heavy weight equipment: CAUTION: Do not lift greater than 50 pounds.
Recommended tools The procedures in this document may require the following tools: • Philips screwdriver #0 • Philips screwdriver #1 • Torx #5 (T5) screwdriver • Plastic scribe Recommended tools...
Screw list NOTE: When removing screws from a component, it is recommended to note the screw type, the quantity of screws, and then place them in a screw storage box. This is to ensure that the correct number of screws and correct screw type is restored when the component is replaced.
