    I basically leave my MBP on 24/7, I just find it more convenient, and often I will render something over night. I've started to notice that occasionally if I leave my computer on for a few days, I hear a fairly loud humming noise. The only way to make it turn off is to restart the mac and then it will go away for a few more days. Does anyone know what may be causing the noise?

    Also is it bad for the hdds if I put my Mac to sleep and wake it up a lot? Usually when I move it from room to room I just close the lid, but then 30 sec later or so I'll just re-open it, is that bad to keep doing that?

    Thanks for help.

    There is not really any damage to the hard drive, but be careful about moving it before the white light pulses to indicate sleep, as when the light is solid, the drive is still spinning, and it will most likely corrupt some data on the drive. :( And the humming is just the fans revving and the sound that ball bearings make when tortured.

    if its humming after a couple of days i would take it back. i've had mine for 6 days now and have not turned it off yet and there is no humming. i kept my iBook on all the time practically and it never had a problem.

    some may say its not worth it to take it in but you never know. it may lead to a bigger problem down the road.

    Update:

    I unplugged my AC Adapter, and then the noise got softer, and softer, and then it died completely........So is it a faulty AC adapter?

    I'm the only one I know with a Mac. All my friends and family mock me for having it. :)......suckers.....

    Would the Apple Store replace it for free do you think, and is the humming potentially bad, or could I keep it if Apple doesn't give me a new one for free?

    to be honest i never know what those "Geniuses" are going to do. i think they should. it may be a matter of how long ago you bought it. if its less then 14 then they definitely will. after that they STILL should. good luck

    Well I bought it from eBay about 2 months ago, and it was brand new in-box. I think I'll go there this weekend then though.

    So does anyone know if the humming would be bad?

    I'm afraid to plug my MBP in now :)

    well my guess would be is that if the power supply is faulty its giving too much power (if it wasent giving enough the computer wouldnt stay on haha). it could just be the fans running at a high rpm.

    I don't think its the fans because when I unplug the AC adapter the sound goes away....

    well the other moving part in the computer is the Hard Drive. thats the only other thing i think it could be. the power supply isnt making the humming is it? haha

    I suppose so....

    I have a question, do I need to schedule a genius appointment, or can I just walk right in and ask someone about it?

    Uh, actually it is required. You can do it in store but you aren't guaranteed to be seen that same day.

    so therefore its not required. i've walked in a couple times without an appointment and didnt have to wait more than 15 or 20 mins. but like i said its really easy to make an appointment so might as well.

    So I just came back, they gave me a new power supply and said if I continued having problems, that I should bring the Mac back and they'd take it to get it fixed.

    I also asked an Apple employee about the 17" graphics issue, and he said in a few weeks they're gonna tell everyone what's going on and what they're gonna do.
