DELL XPS 15 L501X L502X Bottom Base Cover 70FM3

Genuine Dell XPS 15 base cover

This genuine Dell original base bottom cover assembly fits the XPS 15 L501X and L502X laptops. It replaces a damaged or missing chassis underside using Dell part number 70FM3. The assembly includes the battery latch and the base cover itself. Buyers needing a different chassis size or a non-Dell laptop should look elsewhere.

Direct replacement for the factory chassis

The part matches the original mounting points and latch mechanism exactly as supplied by Dell. No adapters or modifications are required for the listed models. Installers must reuse any internal screws, brackets or rubber feet not shown in the product images. Technicians without the correct service manual or tools may find alignment difficult.

Restores structural integrity after damage

This cover replaces a cracked, warped or lost bottom panel on the specified XPS 15 units. The jump is worth it when the original chassis no longer secures the battery or protects internal components. It does not upgrade cooling, add ports or change the laptop’s external dimensions. Owners of other XPS 15 generations or different Dell series cannot use this part.
