hi :D
I have just received a Lenovo laptop for christmas and everything was working perfectly well.
volume worked webcam was fantastic ect ect ..
its been one day now and suddenly my volume has been a bit quiet ?
i thought maybe it was just the song i was playing but i tried playing other songs and movies and they were also quiet .Im thinking maybe i blew the speakers ? im just wondering if anyone else has experienced this or if anyone could help me out . It would mean alot :) thanks
