Replacement lower case for Lenovo 3N 80WG in white.

How to use

Power off the laptop, remove the battery if removable, and disconnect any external power source and peripherals before beginning. Place the device on a soft, static-free surface, remove screws and any retained clips from the existing lower case, and carefully detach the old housing to avoid stressing cables or connectors. Position the replacement lower case so that mounting points and cutouts align with the internal components and external ports, then refit screws in the recommended sequence to ensure even seating. Reinstall the battery and test the laptop to confirm proper fit and that ports, vents and covers are correctly positioned.

Recommendations

Use appropriate-size screwdrivers and non-metallic pry tools to avoid damaging clips or threads. If internal components must be moved to access mounting points, ground yourself to prevent static discharge and keep small screws organized by location. After installation, verify that ventilation paths are clear and that the laptop sits evenly on a flat surface to ensure stable operation.
