L14 gen2 problems(camera & keyboard)

My webcam does not work. I’m sure it’s a hardware issue as it persists in windows and Linux. I already reseated the camera and it still happpens.

The other issue is that it seems the keyboard randomly ignores key presses. I’m not sure what the issue is, but it’s frustrating to type on as it happens randomly and a few times ever couple hundred characters.

Can someone give me some advice on how to self repair these problems? My goal is to sell the laptop once it’s repaired.

Other than those issues, it works really great. I just want something a bit thinner.
