Chosen Solution
Hi. I am a dj and I own a MacBook Pro 15” Mid 2012. Also a MacBook Pro 13” Mid 2012 that I use for my work. I tried to use the 15” for my live sets in the places I work but the only thing I got was getting sucked. The 15” keeps getting in something like a sleep mode but not like the usual one. It doesn’t “wake up” with a touchpad click or a button press. Instead it needs some time and as you all imagine, this is the worst thing that could happen to a dj. Please help me with this. I already read everything in forums like magnets and stuff like that. Nothing worked for me.
Your system will try to go to sleep mode more aggressively when its on battery. Your SMC will do this more so with an old battery! So keep that in mind! Try to keep your system powered to reduce the risk. You can alter your Energy settings clicking on the battery icon in your menu bar
There are a few apps which can help prevent your system from going into sleep mode in the middle of your DJ gig: like Jolt of Caffeine Update (09/28/2020) I think I found your issue! I noted your TG Pro output offered something my system doesn’t show! As it turns out I also have a 2012 15" MacBook Pro 2.7 GHz system which I use answering peoples Q here. Your output shows ‘Platform Controller Die’ where mine does not, as you can see here:
So I went back to double check your model info to make sure you had a 2012 system taking note what CoconutBattery tells us. Then to make sure I wasn’t seeing things I also ran CoconutBattery on my system. As it turns out I had recently replaced my battery. Then it hit me! Your battery while showing it still has 83% of life left the batteries mAh values are much lower than they should be! Here’s mine and yours side by side:
Don’t focus on the design cap as that is just the battery has been programed with. Yours is trying to imply its better than it is, and in my case the battery value is lower than what the battery is really offering! Where did you get this battery?
In general, this type of issue suggests a power management problem or another hardware-based configuration fault that can usually be tackled by the generic troubleshooting steps of resetting the Mac’s Parameter RAM (PRAM) or its system management controller (SMC).
