Hi Bertie1949,
Welcome to the HP Forums! I will be happy to help you with your web cam but I will need some additional information to be able to help you. What is your product number? What is your operating system? What is the problem with the web cam? Are you getting any error messages at all?
Find your product number on a notebook:
