Hi- I just got a new laptop from Hp, a dv6000, and when i started it up and right clicked the battery and made it go to performance mode, the laptop makes a weird buzzing noise. Not loud, but loud enough for the person using the laptop to hear. Its very annoying because as soon as i turn it to powersave mode it stops. The noise is constant when I dont have any apps loaded up. When I play games,movies, i dont hear the sound. I updated everything exept the driver for my nvidia 7400. I cant seem to fiqure out the problem. It sounds like a interferance problem but Im not sure.Hell I dont want to send it back to HP because I just got it and ther tech support sucks....(I cant understand them >.< and I called them last night and they kept putting me on hold making me be on the phone for 2 hours.) Does anyone have anyt solutions for me? I already tried rebooting it and it didint work >.<I also use vista premium as well. Also if anyone tells me to try and reboot the laptop I already tried and it failed.
