    • After removing the adhesive strip you can see that the webcam is divided into 3 logical units:

    • The first board (green rectangle) houses the indicator LED as well as the microphone. The second board (blue rectangle) is just the webcam with the part no. 01HW045. The smallest (red rectangle) seems to be a light sensor board

    • The boards are just glued into place and can easily be pryed out.

    • The connectors between the boards especially the ribbon cable (green rectangle) lose connection over time. This is why problems occur.

    • To fix just reseat all connectors carefully!

    • If you bought a webcam replacement just connect all cables as they were before.

    • I used duct tape to create a stronger bond between the components.

Conclusion

To reassemble your device, follow these instructions in reverse order.

You might use double sided tape to glue the display back to its frame.
