Does anybody have one that thumps badly when turned on?

I have obe that thumbs but it's normal , I guess it depends on how bad it's doing it., make sure there's no load on it when your turning it off

I've had mine for about 5 months now, it didn't thump at turn-on but the voltage would jump all over the place. I've been in it twice now to fix the terminals which were very loose and than had to secure the voltage adjust just to keep the voltage adjusted properly. But sorry no thumping noise, you may have to go inside and secure everything....

Mine thumps when turned on but it isn't what I would consider badly. This is my second pyramid (last one was a different model). It thumped too.I think it's a characteristic of the supply.

Mine rattles. I have been trying to troubleshoot but can't quite figure where it is coming from.

I do not normally turn mine off while the computer is powered up, but yes it thumps if you pull the adaptor.

No I have not noticed any strange noise in mine. Sounds like yours is defective.

Have not had that problem. Suggest a return of faulty unit for replacement.

I can hear a slight sound on mine, along with the light going off. It seems to take several seconds to reactivate if there is constant movement.

I personally don't like mine. I can hear a lot of static and also the power bottom rattles and it's very annoying.

Perhaps you have a bad unit. There is an audible click when it turns on but is otherwise silent.

It turns on, barely, to one sound and thats it, the one that sounds like crashing waves... I am in the process of sending it back. It will be in the mail on Monday.

Assuming the battery is good, it must be defective. Mine is quite loud and I take care not to set it off in error... especially in the garage. :)

No, I didn't resolve it. I tried 3 different ones, and they all had the same noise. Let me know if you end up going with the same model from a different store, I'm interested to see whether this is a problem with Amazon's batch or the entire line. It's too bad everywhere else is so much more expensive than Amazon though...

Did you turn up the volume. That seemed to also affect the vibration and shock.

Mine makes a noise that I was initially concerned about but after reading JcrusR2's answer I can verify that in my case, he is right (The only thing that might be loose is the plastic On Button. The inside should be solid.) Try shaking it and checking to see if the noise is coming from the power button. You can also jiggle the button lightly with your finger and produce the same sound.

I have not had that occur. I wish I could tell you more about what is causing that noise. It might have done so, but I had mine installed by a professional and I was not there for the testing. I have not had a power failure so it has not had to kick in either, so I haven't heard it in operation.

Mine are very weird too. If you just rotate them a half inch sometimes they'll turn on. I think they're just sensitive... One of their drawbacks

Ours makes a ton of noise too. It is very annoying and even wakes our baby up. Did you just call customer service to get a replacement?

I have not wired it in yet. Ones made ban other manufacturer do make that noise when they are powering a load. That is why I purchased this version to test for that. Sorry.
