skim712 Level 1 Level 1

For the past 2 days, every time I've opened my laptop after a few hours or so my laptop would make a whirring noise, turn translucent grey, and have a loading bar.  Then when the bar was fully loaded, the screen was back to normal, but I'd have to wait a few seconds to type in my password or move the mouse.  I've only had this laptop for about 3 months now.  What's going on?

MacBook Pro, OS X Mountain Lion (10.8.2)

    Welcome to the Apple Support Communities


    Open Disk Utility and verify the drive. If it's correct, your computer is starting in safe mode, so reset the SMC >

    Thank you for your suggestion.  Unfortunately, it didn't work for me.  I just opened my laptop just a few minutes ago, and it still did the same thing even though I reset the SMC last night.

    Is the battery OK? 


    By default, when you close the lid on a MBP, two things happen: the whole memory contents get saved to disk into the hibernation image and once that is done the system goes into the low-power sleep mode. When you open the lid, the memory is verified: if no errors appear, the Mac awakens normally. If errors occur, it falls back onto hibernation mode: this means the saved image is copied over to memory before the Mac comes back online. What you're seeing is precisely this loading of the memory from the hibernation image.


    Apparently your Mac is eschewing sleep mode and going always into hibernation. This can be either cause the battery is bad and memory is getting corrupted while asleep OR cause the Mac was set not to sleep, just hibernate.


    Besides the command-line instructions for Terninal, to set or reset this, there are a number of utilities that offer a graphical alternative. I recall one called SafeSleep, used to be free but the developer recanted recently. MacPilot is another one (amongst a zillion other things it lets you do) but it's shareware too.

    I hope it's not a battery issue because this macbook is pretty new haha.  So the only way to change my macbook to sleep is by using one of these graphical alternative utilities?

  • Courcoul Level 6 Level 6

    For all these arcane settings and adjustments there's always a command you can type in Terminal. However, for the sleep/hibernate dealings I have absolutely no clue what it is. Maybe Google helps, or asking in the Unix side of this house (i.e., mac_os/mac_os_x_technologies).


    Or ask a Genius at the Bar. But I get the feeling we're trying to avoid having to go there if possible....

    Oh, that's a bummer... haha

    I'm wondering if it is charger related because I've been opening my laptop without it being plugged in, and it's been fine.  The times when it did grey out is when the charger was plugged into my laptop.  Do you think this is something I'll have to take to Apple to get fixed?

  • Anton Level 2 Level 2

    Exactly the same problem here.

    Was fine till the last firmware update.

    MBookPro 2012.

    Hope Apple fix it soon.

    I have the exact same problem, new MacBook Pro 13", non-retina. I bought the computer in July, and I think it's been going on now for a little less than a week... possibly since the last firmware update. I find that it happens only when I haven't used the computer for an extended period... which is usually in the morning after I've woken up. At night, I've only ever had the computer plugged in. Please fix this problem, Apple! It's not a horrible bug, but it makes many question whether their computers need to be repaired.

    Here is what happen here : my MbPro (late 2012) is closed and in charge - i just unplug the power cable and ear the "going in stop" mechanichal sound. When i'm opening the MbP it is freezed -> it just resume after some seconds. In the whorst case it is completely "greyed".

    Please Apple do something : it was fine till the firmware update.

  • Anton Level 2 Level 2

    ...anyway it's a nightmare.

    All the times i reopen my MBP the issue coming up.

    Dear Apple, if you read this : do i have ask for a logical board replacement or You have planned for a new firmware ?

    Appreciated any answer.



  • heatwaveo8 Level 1 Level 1

    I still haven't seen a firmware update to fix this. I'll send a bug report to Apple and see whether they list it as a duplicate.

  • Anton Level 2 Level 2

    I've sent a feedback report. That issue is very annoying.

  • Anton Level 2 Level 2

    Update, it seems i get this only if the powersupply is connected.

    If not  awake it's fast as it normally.

  • heatwaveo8 Level 1 Level 1

    K sounds good. I've gone ahead and issued a bug report as well. Here's my experiences with this, after keeping the computer asleep for more than 4 hours:


    1. If I don't use the charger during sleep, it works like normal.


    2. If I leave the battery plugged in the whole time and open it with the battery plugged in, I get a semi-transparent screen, as though the battery had died, with a loading bar. After the loading bar goes away, I see my content. The time goes up 4 hours from when I put the computer to sleep, and a couple of seconds later, the time becomes correct.


    3. If I leave the battery plugged in the whole time and unplug the battery charger, the computer makes a noise as though it's awaking from sleep. Then when I open the computer, I get a gray screen for a couple of seconds, and then it loads my content and updates to the correct time.
