Okay, so my 2012 cMBP seems to be having an issue. If I plug it in and let it charge for a few hours and I open the lid while its still plugged in, it'll wake up from sleep instantly. The same goes for if its unplugged for a few hours and put to sleep; if I open the lid, it wakes up from sleep instantly. Now here's the weird part... if its been charging for a few hours and then I unplug it and open the lid (what most people do - I usually let it charge overnight and then unplug it and open the lid in the morning to start using it) it will take anywhere from 15-30 seconds just for any of the backlights to turn on (this includes the display, the keyboard... anything) and also, none of the buttons are functional. Nothing works for those 15-30 seconds until it finally wakes from it's (deep) sleep. The only thing that it responds to is holding down the power button for about 10 seconds, which causes it to forcibly shutdown. How can I fix this issue? Do I need to reinstall OS X? Also, this is the latest version of OS X. Is there any terminal commands I can do to fix this. It's extremely annoying and has been doing it for months.
