Question

acwake 0 but it wakes up when I plug charger in/out, acwake 0 but it wakes up when I plug charger in/out, acwake 0 but it wakes up when I plug charger in/out

I have MBP 15 inch mid 2012 and I think there is something wrong with it.

My acwake is 0 but whenever I attach/dettach charger the computer starts breefly (2-3 seconds) and then goes to sleep again. It does not matter if I close the lid or I go to sleep from the apple menu.

Battery Power:

lidwake 1

autopoweroff 0

autopoweroffdelay 0

standbydelay 0

standby 0

hibernatefile /var/vm/sleepimage

I already erased

HD/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist-orig  
HD/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist  
HD/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist

But it did not help. Its the same. Did reset on PRAM & SMC. I did everything that I can think of. Any help?

Aditional info:

In console I get

See this thread for some valuable info. Suggest you read the whole thing, espeically the part about the new EU regs.

They don't need to fix the actual behavior when standby or autopoweroff is enabled because we can disable those settings via PMSET and not use them if we don't want them. What they need to fix is the issue where unplugging/pluggin in the AC adapter causes the system to wake up and change modes. That's the unnecessary part really.

I've been reporting it as a bug where the system ignores the acwake 0 setting when standby or autopoweroff is enabled. If they could just fix this part of it, I'd be happy.

My MBP suffers from the stupid autopoweroff issue mentioned in the thread by BigGee42 above. So I disabled autopoweroff only to find that now my MBP will wake whenever AC is plugged on/off and often not go back to sleep. This is really annoying. Of course acwake state is 0. Filed a bug report.

Sadly, the newest version of OS X - the Meverics - does *not* solve the issue either :/

Yep and I believe that they've set the OS to ignore the StandBy settings as well because even enabled, the behavior isn't the same as in Mountain Lion. They're idiots!

Just call them and tell them. Or fill out their feedback forms. It's about all you can do at this point it seems.

I just baught a Mid2012 MBP from refurbished store and obviously have the same problem.

I will call AppleSupport for reporting after exams are done next week.

But thanks everybody for giving all these information about the reason. I have been looking for hours.

Hi!! I have the same problem... I think

It only started when I updated my mac, bought in mid 2012, running on Lion, to Mavericks.

Be careful because before I noticed it overheated a few times, and I'm pretty sure it burned down my logic card.

I went to the apple store and explained that since my update to Mavericks my computer would wake up in sleep mode and it overheated 3 times before I noticed that it would happen when I unplug the charger. After the 3rd time, my computer started to freeze all the time and I would get lines on the screen. Apparently my logic board fried or something and the temperature sensors were broken too. I have a feeling that's because it overheated and was running on sleep mode in my backpack.

I still had to pay 622$ for a new logic board. The employees told me that replacing the board would fix my freezing issues and also the sleep mode problem but IT DIDN'T fix the sleep mode. And two of them seemed to not even believe me when I told them that it was doing that, and only after Mavericks.

So it's all in my head, an update could not possibly create that issue, and my mac fried out of the blue, and it's just a coincidence they said... Very frustrating. I have the feeling that if I had never updated my OS my mac would have never broke and I would't owe 600$ to the bank -_-

HOW DO I FIX THAT BEFORE IT OVERHEATS AGAIN? Help please 😟 !

This is not a hardware problem, it is Apple's bad coding due to their sometimes careless attitude.

Very recently I purchased two 13" MacBookPro9,2 just before they become discontinued. I need optical drives on my computers.

I have no this issue on my older MacBook Pro's and I have quite a few of them.

This behavior is not just very, very annoying but it is also dangerous because the potential risk of overheating and HDD damage is real.

I simply can not believe that Apple still did not take care of this issue. After so many years.

Come on, Apple! Get yourself involved!

This particular model is the longest produced MacBook Pro ever. There is a reason to put some efforts and finally fix this software issue.

Running El Capitan, Version 10.11.6 (15G1212).
