ok, judging by my posts recently im sure ppl can tell im not very knowledgable about technology, but u gots to help me out here! my mac keeps on humming subtly and it is doing my head in, however once i literally lift it off the desk so its no longer making contact with it, it goes completely silent! i need it to be silent as well cos when i try recording my bongos nearby the mic picks up the humming too. any idea why its doing this?

thanks very much!

macbook pro? they just do that.

be glad you don't have an old g4 powermac-- that thing was a beast. like living near the airport.

If you lift it off the desk and it stops humming....
Try putting some foam or summit under it?

yeah just sounds like it needs isolating fom the desk, just stick something under it, something that can absorb a bit of vibration like packing foam. i have a laptop that does something similar, but i have put the foam bits from its box around it (well a few mods made to allow air flow to keep it cool) and its silent apart from the fans (its a p4 cpu in a big ol laptop so gets hot, but with the foam its raised and gets airflow so doesnt overheat, even in very hot club conditions)

cheers for the feedback lads

Are you sure you didn't have a fan issue? I had two G4's and they weren't noisy at all.

Do you mean your actual computer is emitting a 'hum' or that there is a hum coming through your monitors and you figure it's originating in your computer?

If the second is the case then get a ground loop isolator, did the trick for me.

Maybe someone took a dump in it.

that only happened the one time

@demonicman its emitting the hum, its not as noticeable at the moment though

yeah but cheapo isolators like that one will degrade the signal to your monitors. The only studio grade isolator I know of is the ART Dual Transformer/isolator, but even that isn't totally perfect.

I know this because I was stupid enough to purchase a Dell laptop which has awful ground loop noise if it isn't isolated

you can get a behringer active DI box for hum probs.

Or just forget computers and go old school !

and then its a whole different (but nice) world of hums and interference.
