Not a Long Time ago I purchased a 2011 13-inch Macbook Pro. Now, when you shake it or you know when carrying it and you might move it, it makes a beeping noise. now, is this normal because my friend also has the same model and when you shake it, it makes a clicking noise. Are all the 2011 13-inch MacBook Pros like this. Please HELP!!!

    Yes this is normal. When you move the laptop around close it, wait about 5 seconds and move it.Try not to shake it too often because it is not good for it.

    It is not normal for a beeping noise. Mine makes a click.

    It is the Sudden Motion Sensor kicking in.

     

    Clicking noise is normal.

    Having clarified the source of the noise and the recommendation not to shake it too much (you wouldn't shake a baby, would you?), here's a tidbit you can install to watch the Sudden Motion Sensor do its thing:

    The beeping sound has my concern.  That by my thinking should not occur.

     

    In regards to the clicking sound, a similar post several months ago that registered the same complaint.  My response was that this was not normal either.  Why?  If I shake my two MBPs as if I were making a martini, they are absolutely silent.

     

    Now I suppose that my hearing is such that I can't hear noises from my MBP anymore or my MBPs are abnormal.  I vote no on both counts.

     

    Ciao.

    If the Mac is running when shaken and the SMS detects a potentially hazardous acceleration, it will park the HDD heads to prevent damage. Until the SMS gives an all-clear and releases the HDD, no read/write operations are possible. The beeping may come from the OS or an application that tried to access the drive and was rebuffed. Perhaps a browse thru the various logs can yield detailed info.

    Courcoul, greeting friend;  I looked for that old thread but having the patience of an 8 year old I quit after 15-20 minutes.  I do recollect being the lone nay sayer.  Maybe the 17" MBP are silent and the others are not?  Stupid logic.

     

    Nothing in that thread mentioned beeps or sounds of that nature.  Only clicks.  That is the enigma for me in the case at hand, thus my concern.  My concern is based on the assumption that this occurs when the MBP is shut down.  If this is when the MBP is running, you are probably in the right neighborhood.

     

    Ciao.

    Why do you shake it?

    Maybe he wanted to hear the floating point processor???

    I was told age brings serenity and patience, but there are always exceptions....

     

    My logic for hipothesizing a cause for the beeps is that I've had the things beep at me when they can't do something minor and maybe the OS told the app to wait a sec for things to quiet down. As for direct experience, in ye olde days my two previous 15" MBPs would buzz at me like angry bees when I tripped the SMS but a humongous 17"er would have a deeper voice; more Caruso than Carreras, if you catch my drift. And no, I will NOT shake my new baby to test. Not even for you!
