    Hey guys, I have a Late 2011 13" MacBook Pro with a 500GB SSHD and 6GB of RAM (thankfully with integrated GFX) that beeps 3 times while sleeping. I've reinstalled OS X and put a new hard drive in it. Also, I have tested the RAM, it reports its working fine.

    It only appears to do this when going into a 'safe-sleep' or 'hibernation'. When it does this, I usually have to hold the power button. I've tried the instructions from this page. (a.k.a sudo pmset -a hibernate mode 1), but its very annoying to wait for you MacBook to reawaken (progress bar) after sleeping for a couple of seconds.

    Anyway, sorry if this post was long, I wanted to include proper information.

    (and yes, I've reset the PRAM/SMC)

    6GB of RAM? Or did you mean 16?

    Loud beeps or soft beeps?

    Sleep on battery or sleep on AC power or both?

    Turn hibernate off.

    Try this to set everything to old-school sleep.

    sudo pmset -a hibernatemode 0 darkwakes 0 standby 0 standbydelay 0 womp 0 autopoweroff 0 autopoweroffdelay 141006540

    1. 6GB. 4GB + 2GB.
    2. Loud.
    3. Both.
    4. How?
    5. Trying now.
    EDIT: That command ended up causing my MacBook to not wake from sleep. Opening the lid resulted in the light (bottom left 'sleep light') to stop shining for about 4 secs and then coming back on. Couldn't wake with the keyboard/trackpad.

    the beeping is a warning from the hard disk that it is not getting enough power.

    i have 4 seagate hybrid drives and i am well acquainted with the beeping sound

    other then SSHD i Never ever heard of a mac beeping when it is asleep. unless it was TOTAL RAM FAILURE

    mac goes to sleep, lowers power to SSHD and the SSHD starts chirping to tell you its not getting enough power.

    SSHD requires 5 v @ 700 ma

    recommend restoring to a conventional hard disk to rule this out

    a mechanical 7200 rpm would be okay to try out

    if it fixes it, then i am right, otherwise, your hard disk will probably overheat and die


    i am sorry to give you bad news.

    another quick way to rule out this crazy but true post of mine is to pick up your computer while it is sleeping and and making that beep sound and stick it to your ear to listen for the hard drive spinning

    if you can't hear the drive spinning but you can hear the beep, it means you really shouldn't be using that drive.
    --------
    you know.. this could be the most incorrect mac rumors post ever. i don't care but you have to take the time to rule out that it is not the SSHD that is beeping!!!!!

    i am dead serious. a beeping sshd means that the hard drive IS NOT SPINNING and is OVERHEATING

    It can mean that there isn't enough power to drive the SSHD.

    Hybrids are never a solution. Go get yourself a full SSD.

    You wouldn't by chance have Google Drive installed would you?

    I can't afford one, I live on a shoe string budget. I've put this same Hybrid drive in another Macbook and it worked flawlessly.
    My last mechanical HDD drive did this, it was an apple replacement.

    No, I don't.

    Sorry for the late replies, I was struck by the flu.
