So just before class started I was carrying my laptop like a book, as i normally do, and I heard a rattling I’ve never heard before. Then I got feedback from the speakers during class. And it’s been running slow, especially the internet stuff. Some applications are unresponsive. Are these things all connected? If something is loose in my speaker, could it have damaged other components? Can this be repaired? Don’t know if it’s relevant but the hard drives only 3 years old.
