    I have been looking online and getting mixed results regarding buzzing noises from ac power adapters. My old hp dv6000 laptop powerbrick did not make buzzing noises as loud as my new dv6-1235cl from costco.

    I noticed that a lot of people now hear buzzing noises from their ac adapter. Then I came onto this website.

    Is this a bunch of bs or are they for real?

    I can hear the buzzing noise when I put my ac adapter on the table, but almost non existent when its on the ground. I want to know if this will be a fire safety hazard in the future? I dont want my house burning down even when this thing is plugged in.


    Thanks much guys

    It's normal. Poorly wound coils will make noise, and there seem to be an abundance of them lately. It shouldn't be happening, but it's not going to explode either. They have an internal safety fuse anyway so the worst thing that could happen is a bit of molten plastic on your carpet.

    The power brick of my DV5 buzzes enough to be noticeable about 1 meter away, while the one on my DV9700 is only audible if i put my ear on it. Blame the Chinese i guess.
