Replacement Power Button Cover for Latitude E4300

This genuine Dell part replaces the center control power button cover on the Latitude E4300 notebook. It is identified by part number M640D and is supplied in new condition. Buyers must verify the part number before purchase because two different center power button covers exist for this model.

Correct Part Selection Avoids Fitment Issues

The listing notes that two distinct center power button covers were produced for the E4300, so matching the M640D number ensures the cover aligns with the specific chassis variant. Ordering the wrong variant would leave the power button mechanism exposed or misaligned. This accessory does not add new functionality; it restores the original switch protection and tactile feel.

Limited to a Single Laptop Model

The cover assembly is designed exclusively for the Dell Latitude E4300 and will not fit other Latitude models or Dell series. It addresses only the center control button, leaving other keyboard or palm-rest components unaffected. Users needing a different button cover or a complete palm-rest assembly will require a separate part number.
