Enable "standby mode" for MacBook Pros I can't get my 2012 13" MacBook Pro to standby (note: NOT regular sleep, see http://support.apple.com/kb/HT4392).

My pmset -g results are:

Anyone has any idea what might go wrong which would prevent standby? Note: regular sleep works fine, but it does not enter standby after a period of time. I also reset the PRAM and SMC.
I don't think it's supported on your 13" MacBook Pro. From the KB article you linked (emphasis mine):


  Apple Portables that support standby mode are:
  
  
  MacBook Air (Mid 2010) and later
  MacBook Pro (Retina, Mid 2012)
  


I parse the text in italics to mean the Mid 2012 Retina MacBook Pro, not "Mid 2012 MBP and Retina MBP". This is further corroborated by the reference to the flash storage later on, which is only included by default on the MacBook Air and Retina MBP.
