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)
