If I were you, I would test Ubuntu on an usb stick (or other removeable media) to start with to see if it behaves happily with things like the wifi and microphone/camera before reformatting the hard drive and installing it properly.
I was given an old Acer Vista laptop recently on which Mint did not recognise the wireless card.
I probably could have made it work with some effort but as I wanted to use it in the garage, which has a wired connection, it was not a problem.
