MacBook switches to hibernation during sleep

I read a while back on this thread, someone made a connection between routers and this probelm. I turned my wifi off last night before closing my computer, and it didn't go into hibernation. Interesting!

I still plan on doing the autopoweroffdelay "fix" but I wonder how/why the wifi connection plays into this.

This is so weird that this conversation has to be had on a computer built in 2012, w/0 any sure fix. My new 2012 get's that weird loading bar when i come out of sleep. Is that what we are talking about here? I don't quite understand this thread fully. Yes, i've read it! Ive changed my pmset to 0 instead of 3, that's all i can remember right now! Is this thread a fix for not having that stupid loading bar when waking your cmputer? lol. I find I open my laptop early just to load it, then i wont even use it, WASTING MORE POWER?! Anyways, your response have been appreciated, and i feel like im learning something.

For what it's worth I was at the Apple Store today and checked 3 different MBP's on display with pmset -g. Not one even had the autopoweroff command visible, never mind having it set to 0 or whatever. They were all running 10.8.2 so I assume they deleted this command completely since they probably leave these things running all the time and don't want them to hibernate. Just curious that they didn't bother setting it to 0 but just removed it altogether.

Hmmm. The ones I checked in Nashville all had the settings available and visible. They were set to '1' and the delay set to 14400, which is stock. Those were 13 inch Macbook Pro with Retina. I couldn't get to the regular MBP. Too many people around.

If someone wouldn't mind, answering this post i'd be very greatful.

Mainly, is this post trying to address the loading bar coming out of sleep?

Yes, this post is about the 'loading bar' coming out of hibernation sleep.

There are a few different solutions, you can read the thread if you want other options. As for me, I put

sudo pmset -a autopoweroffdelay 86400

into terminal and this sets a delay of 24 hours, so you'll rarely, if ever, see your computer in hibernation again.

This is my first ever post on the discussion boards, so if I ramble a bit I'm sorry. I'll try to make it short and sweet. I want to use the "autopoweroffdelay" fix to set the delay to 24 hours, but I've run into a bit of a problem. When I use the pmset -g | grep autopoweroff command, it does not bring up current values like you said. I am hesitant to change anything until I can make sure that the values match the ones that you suggested.

Also, will changing this affect my MBP's ability to go into hibernation when the battery is completely depleted in battery mode? I still want my machine to go into hibernation mode if I leave it until it dies completely. I just don't want the delay to cause it not to hibernate when the battery dies. I want the Mac to run as closely as it did before the 10.8.2 update.

Hopefully I'm making some sense. Like I said, I just want my Mac to run as I know it should. I'll say that this isn't my first Mac. I had a 13'' MacBook White, early 2008 model, before I upgraded to the 13'' MacBook Pro, mid-2012 model that I'm using now. That old MacBook only went into hibernation when the battery died. I want this one to do basically the same thing. I'm sorry if I rambled. I'm going to check the developer page you suggested also, just to see if I was typing something in the Terminal incorrectly. If I get it fixed, then I'll try and post an update, but I might be so excited that my Mac is back to normal that I just forget about it. I've been searching the internet for over a month and half trying to find a fix, and it was only today that I finally figured out the magic words to type into the search bar that lead me to this thread!

Hello all,

Just wanted to reply as I'm also having this issue.

I took my Macbook 15" Mid 2012 10.8.2 into the Apple store, explained my problem and they hadn't heard of the fault before. As the Mac is brand new they told me to ring the Apple helpline and report the problem to obtain a replacement machine as there was a hardware fault.

New machine has arrived and after using TimeMachine the fault has followed me onto the new Macbook. As much as I like the ease of TM it's a shame that the problem has copied across too.

I hope that this glitch is being looked into and an update is released soon. As I do hate seeing the hibernation screen so often.

ive just followed the guidance from these post's and I havent seen that pesky loading bar ever since! Thanks guys 😀

Taxipalm would you mind just letting me know which setting inparticular worked for you?

Many thanks.

I did what this article said to do first

http://www.macworld.com/article/1053471/sleepmode.html

i still got the pesky loader after a long while sleeping

then i used this one sudo pmset -a autopoweroffdelay 86400 second,

and i havent seen it since

I think we've established this has nothing to do with Time Machine nor should Apple have bothered replacing your MBP. This is a change made in the 10.8.2 update and if you follow the directions in this thread re Auto power off you will eliminate the problem.

I've just put sudo pmset -a autopoweroffdelay 86400 into Terminal. So let's see what happens in the morning.

As hockeymagnet said, this probably has nothing to do with timemachine. I also recieved a replacement mbp and it has the same issue as the first one (I don't use timemachine, nor add any of my data or programs, and the hibernation still occured, basically with the computer clean and fresh out of the box).
My spouse has an identical computer that has NOT been updated to mountain lion (muchless the infamous v10.8.2), and his computer does not go into hibernation.

I suggest changing the autopoweroffdelay as others have, It's what I did and it has resolved the issue for now.

Good luck!

I wanted to chime in and to say I have been having the exact same problem. I bought a new MBP on Jan. 3rd. For the first few days it worked fine and then this past Thurs I started getting the gray screen in the morning after charging it all night. I waited to see if it came up again on Friday and it did so I called Apple Support. They ran me through a couple of things. Saturday it came up again, called Apple Support and they referred me to my local store. Went to the local store and he thought maybe I was draining my battery. So Saturday night I made sure I was not draining my battery before charging it overnight (I knew I wasn't the other days but I wanted to appease him). Sunday same gray screen. Went back to Peachmac. Got a different Service guy. He tested the power sources and they were fine. I asked for a replacement since it was less than 14 days. They gave me one (the manager was not happy but he allowed it). They transferred all of my data. I do have to add that I had another MBP that was almost 2 years old but I spilled pop on it so it is not working right now and I can't remember which OS I have on it but I am pretty sure I have the most update to date OS on it and I did not have the GRAY screen. I got home last night with the new one and I had to immediately update to the most recent Mountain Lion OS 10.8.2 bc it wouldn't open iphoto and then it had me do another software update. I charged my computer ovenight and the GRAY screen appeared this morning!

I was glad to find this thread to see it is a common problem. I am hopeful they will come out with a patch soon. I think I will sit tight for now. I may try to charge my laptop during the day or before I goto sleep at night. I may also try to shut it completely down at night to avoid this problem or now.

Let's hope they do something quick, I think they will begin to hear more and more of this issue.
