Last day in New Zealand

Today is the last day I have in New Zealand before heading back home to Japan. I have received my new laptop, and all is well except the integrated microphones. I have seen many people have similar problems with HP laptops and the high definition audio. HP support wasn’t any help, they suggested that they send round a technician to look at the problem. Thing is, if its a driver issue I don’t mind as that can usually be fixed eventually. If it is a hardware issue, thats another story. So when I get back to Japan, I’m going to get another hard drive and install another operating system to see if the issue is still there. Hopefully it isn’t and its just a problem with vista or the drivers.
