Disassembly Requirements To disassemble the computer, you need the following tools: •Wrist grounding strap and conductive mat for preventing electrostatic discharge •Flat screwdriver •Philips screwdriver •Plastic flat screwdriver •Plastic tweezers NOTE: The screws for the different components vary in size. During the disassembly process, group the screws with the corresponding components to avoid mismatch when putting back the components. IMPORTANT:Various images depict the use of a regular metal screwdriver, however, a plastic screwdriver is advised when disassembling parts near or around the motherboard and to prevent scratching of the computer surface.
