    Hi,

    I got the dv6000t with T5600

    I have a buzzing sound come out of it when it's plugged in,
    and more loud when it's on battery

    Anyone know what to do?

    It is could just be the hard drive. Is it a continuous buzz or do you hear it start and stop?

    It's continuous.
    I don't think it's the hard drive cause it's on the left side and the sound is from the right side and center.

    you have a grounding issue which is causing your speakers to buzz -- or such would be my guess. i had that happen before. got a new power adapter and put a new sound card in my laptop to fix it (the grounding issue destroyed my soundcard)

    are you sure it's the speakers?
    even when the sound is off the buzz is going on and no buzz on earphones and external speakers.

    If it's a low loud buzz, try switching the laptop off while it's buzzing. If it slowly winds down then it's the cpu fan. I had a buzzy fan on my old Toshiba Portege.

    If it's a high pitch and frequency buzz like a bee... see some of the other suggestions!

    May be a cooling fan or OD. Turn it upside down to help isolate the sound, be able to provide more info in relation to exhaust vent ports ;) No idea why on battery would be louder :confused: If an internal wire was being brushed by a fan, would think sound stay same.Describe noise better!
    My brand new after market DVR-K06 was silent, but now on startup (~+2 months) w/ a CD inside, makes a noise before the drive spins up & begins reading optical media!

    it's high pitch

    is there a fan on the processor other than the one that turns on and off and you can hear it?

    If you put the laptop under stress, such as playing a game, does the noise change, like getting louder? If so, its most likley a fan.
