Introduction

If your webcam suddenly fails and can be revived by flicking or tapping on the case near the webcam you probably have a loose connection and the webcam board must be reseated.

  • Remove the 10 Torx TX5 screws on the bottom case
  • With all screws removed pry off the cover with your fingernails or use a spudger.
  • The cover should off quite easily.

  • With the cover removed you will find 4 screws to be removed (red circles) as well as two strips of adhesive (green rectangles) you have to pull.
  • After unscrewing the four screws use a pair of tweezers to pull on the tabs of the rubber adhesive strips.
  • Be patient while pulling and avoid ripping off the adhesive strips!

              Webcam removal

  • To proceed you have to unplug the ribbon cables like you did before on the mainboard.
  • Lift up the tabs and pull out the cables.

Step 11

              Inspecting the logical boards
  • 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.

Step 12

              Tinkering and reseating
  • 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.
