This is a genuine OEM Lenovo LCD back cover (also known as the C-Shell or screen lid outer panel), part number 5CB1M72405. It forms the outer face of the display assembly — the part you see when the laptop lid is closed.

Material & Build: The cover is constructed from reinforced ABS plastic, the same compound used in Lenovo’s own production line. The surface has a standard Lenovo matte finish. The internal side features recessed channels to guide antenna cables cleanly from the hinge area to the wireless card below, preventing pinching or signal degradation during reassembly.

Common failure symptoms that indicate replacement: cracked, snapped, or bent screen lid (often from drops or pressure); deep scratches or gouges to the outer surface; lid no longer closes flush due to hinge-mount damage on the cover; damaged or missing Lenovo logo area; cover deformed by heat or impact. Note: this part is the outer shell only — it does not include the LCD panel, bezel, camera, or hinges themselves.

Replacement process overview: Power off the laptop and disconnect all cables. Open the lid fully and locate the hinge screws on the underside. Remove the screws securing the hinges to the old cover. Carefully detach the antenna cables from their routing channels inside the lid. Lift the old cover away. Transfer the antenna cables into the new cover’s routing channels, seat the hinges and secure with screws. Check lid closure and alignment before fully tightening. Verify there is no gap at the hinge line when closed.

Compatibility note: This part is identified by Lenovo part number 5CB1M72405. Always verify your laptop’s exact model number (found on the service tag label on the underside of the unit) before ordering. Using an incorrect cover may result in hinge misalignment or antenna routing issues.

This part is suitable for professional repair technicians, IT asset refurbishers, and experienced DIY users who need a reliable, genuine OEM lid for a Lenovo IdeaPad or Yoga series laptop.
