MBA goes into deep sleep on OSX, wakes up and boots Win7??

I recently picked up my new 11" MacBook Air (1.6, 4GB RAM, 128 GB HD) and because I'm graduated student, there are a few programs that I need to run under Windows 7. So I used boot camp to install a legit copy of Windows 7. That all went fine, so now i have a nice dual-boot MBA.
Here's the problem. I know that the new MBA models have a new sleep mode when you close the lid. there's a short-term sleep and a long-term sleep as far as i know. 90% of the time i'm in OSX (10% in Win7). When I close the lid for a short amount of time (up to an hour maybe?) and then open it back up again, it comes right up, no problem. But whenever its been closed for a longer period of time and I open it back up, instead of it OSX popping back up on the screen, it starts booting Windows!! VERY frustrating! What the heck is going on here?? This happens pretty much every time without fail and is very easy to replicate, you just have to wait the requisite hour or so until i know the MBA has gone into the deeper sleep mode.
Anyone else running Boot Camp and running into this problem?

Hi kdolson,
Interesting issue you're experiencing. I have the new MBA as well, as well as several machines configured for Boot Camp, and none of them experience this issue. I've let my new MBA sleep for 10+ hours undisturbed and OSX fired right up. I'm wonder if something funky is up with the partition map on your HD.
What is set for your default startup volume, Windows or Mac? By default when you Boot Camp the machine and install the drivers/Boot Camp support files it sets the Boot Camp volume to be the default startup volume. I wonder if that's perhaps the issue. Regardless, this shouldn't happen (deep sleep the machine and have it wake to another boot volume)
It's probably worth reaching out to Apple on this.

I have a new MacBook Pro Mid 2012 and it goes into deep sleep when I disconnect if from AC power.

I have a new 13" MacBook Pro mid 2012 and it goes into deep sleep when it is disconnected from AC power. I have to press the power button to wake it up. Is this a known issue or is there something wrong with the MacBook Pro?

There are a few threads about this around. Its a known issue for 2012 non retina users, not sure about Apple. It should not work this way and Apple has not put out an update to fix it yet. Check out these threads for some workarounds. I think I saw if you reinstall and don't update one of the updates you get normal functionality back. Otherwise there are some terminal changes you can make to make it operate mostly normally. I made some changes in terminal.

My (2008) macbook pro, running 10.5.8 runs for about 30 seconds and then goes into deep sleep mode. After significant difficulty awakening, it runs for 30 seconds and....start repeating here. It did this once before about a year ago.

.....and then goes into deep sleep mode. When it (finally) awakens....it runs for about 30 seconds and.....start repeating here.
And yes, I've shut dwn and restarted multiple times, rebooted in terminal mode and run fsck, rebooted and reset the parameter ram, yadda-yadda......
Anybdy got any ideas?

Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on Mac portables with a battery you can remove
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery (to remove the battery - click here: MacBook or MacBook Pro).
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.
Still having problems? Replace steps 6 and 7 with the following:
Reconnect just the MagSafe power adapter.
Press the power button to turn on the computer,
Then reconnect the battery.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. The power adapter indicator light may cycle off / on once.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

Help: Macbook goes into deep sleep instead of sleeping

Any time my Mac is supposed to go into sleep, like when I leave it alone for 15 mins or close the lid, it goes into deep sleep (hibernates). How do I fix this?
Also, it started happening after I changed the starup disk from Windows to OS X through the boot camp control panel in Windows.

Just reset the SMB following these instructions: http://support.apple.com/kb/HT3964 and still having the same problem. However I realized two key things:
The computer goes into Deep Sleep mode whenever I tell it to Sleep (Even if I use the Sleep button in the Apple menu)
The above only happens when the power adaptor is plugged in. When running on batteries Sleep seems to work properly
While typing this up I just realized that a widget I have called Deep Sleep for dashboard might be causing my problems, and sure enough... it is. Apparently there is a setting on there that lets you make your Mac's "regular" sleep mode Deep Sleep and I probably turned this on without realizing it. For anyone who's reading this I'll try to keep you posted on if this fixed the problem or not... if I don't post anything else on here you can assume it's fixed. Watch out if you use the Deep Sleep widget

Qosmio X500-116 - goes into deep sleep

I have had the above computer since February 2010, and over the years I have had many problems. I have been inclined not to use it as each time it gives me problems.
Today I thought I would try to see if I can find a solution. I switched on after charging the battery for about an hour and it booted up in around a minute, not bad. I updated my Norton Internet Security, this completed and I checked my incoming emails and sorted them. I left it for about 10 min (had a quick coffee). on my return the screen was blank and I just can't get the screen to come on at all. This happens almost6 every time I try to use this computer.
The only was to get things going is to hold the start button down till the laptop shuts down. then press the button to start it, It then runs through all the loading of windows files after I select "Safe Mode" I have tried all the suggestion of options and never got anywhere. If I just select restart things go back to normal. I can log in and all seems ok. and I can do what ever I need t do.
I try to keep it active, If I leave it for any time it goes back into the unrecoverable sleep.
I have run Norton "Scan Now" on both hard drives, no problems found.
One a few occasions I have seen an odd coloured screen (multicolour) not what I would describe as a Blur screen. I did wonder if it could be a graphics card issue, perhaps not.
Any suggestions?

Hi Ivan 25, thanks for your interest.
Currently I have the on battery setting:- Dim the display 1 min, Turn off display 2 min, Put the computer to sleep Never
and
Plugged in to the mains: All NEVER.
I never run it to battery only it will go into a "deep sleep" and nothing apart from a Hard shut down will allow me get it up and running again.
Plugged in to the mains allows it to keep on with no problems.
To be honest since new this has been an issue since new, but it was not so bad in the early days. Hence my reluctance to use it very much.
Sorry I did not say, it's the screen that goes to sleep NOT the hard drive.

Mountain Lion crashes when going into deep sleep?

Hey guys,
I recently upgraded to mountain lion from lion on a late 2011 MBP.
I have no problems during the day time with anything, but when I leave the computer to sleep overnight it doesn't wake up in the morning.
It shuts down and when I try to turn it on it gives me a pattern of 3 consecutive beeps. Sometimes it doesn't give me any beeps and just gives me a grayed out login screen and a bar loading on the bottom. In the latter case, it does eventually wake up but with the beeps it's a no go and I have to hold the power button to restart it. I never had any of these problems in Lion. Any thoughts as to what this could be?
I tried PRAM, SMC Reset and creating a new user account. I also ran an extended Apple hardware test which reported no issues.
This is the log preceding the crash/shutdown:

I can't deal with this issue, because I like to use my macbook to charge devices overnight and that's not possible with it shutting down. So if there is no solution what's the best way to go back to Lion?
Am I the only one with this issue?
Thanks for any help.

It sure would be useful to be able to look up these Failure codes. Searching apple's site like this produces strange, useless results.
I see Failure code:0x1F006500, like the OP; googling for it brought me here.
Similarly:
I recently upgraded to mountain lion from SL on a MacBookPro4,1 -early 2008 MBP (expired AppleCare), and switched to booting off an SSD in the ExpressCard/34 slot.
When I leave the computer to sleep overnight it doesn't wake up in the morning. It is completely off, and boots from scratch when I turn it on. It can sleep briefly.
I have NOT tried PRAM, SMC Reset or creating a new user account, or run an extended Apple hardware test.
From the output of pmset -g log
9/27/12 7:39:04 AM PDT   Sleep
Sleep (Failure code:0x1F006500): Using BATT (Charge:48%)
Strangely, there's no mention of 'hibernate' in my log files after 19:03 last night, even though I was up 'till 'round midnight.

My EE box keeps going into deep sleep cant turn on tv for ages

brightbox wont come out of deep sleep for ages

You need to give us more information, otherwise we cannot help. My EE TV has not done that, but if it is your EE TV box, have you tried resetting it? There is a reset button under the box, small, and you will need something like a pen to push it to restart and reset. You will have to put your wifi details back in etc.

MacBook Won't go into deep sleep by itself

I recently noticed that although my monitor will go to sleep after the specified idle time the hard drive never goes to sleep on it's own. The indicator light never goes into "pulse mode". The strange thing is I think it worked fine before I did the recent updates.
I can put it to sleep through apple menu, CMD:OPT:DEL, or by closing the lid. Those methods all work fine but if left unattended it never goes into deep sleep and eventually drains the battery completly.
please help.
Thanks,
Chris
MacBook 13" 2 GHz Mac OS X (10.4.7)

It doesn't seem to make a difference if it's plugged in or not. Closing the lid puts it into deep sleep. Unplugging or plugging it in while it's asleep doesn't seem to effect it.

Hi Guys 'n' Gals!
I have a problem with my computer not going into 'Display Sleep' mode but actually goes into full Computer Sleep mode. Anyone know how to keep my Mac running software and not go into full sleep after I have set it to 'Never' go into 'Computer Sleep' within the 'energy saving' section!
Any ideas guys?

I pull fiftyfour bytes of data from MicroProcessor's EEPROM using serial port. It works fine. I then send a request for 512 bytes and my "read" goes into loop condition, no bytes are delivered and system is lost

I pull fiftyfour bytes of data from MicroProcessor's EEPROM using serial port. It works fine. I then send a request for 512 bytes and my "read" goes into loop condition, no bytes are delivered and system is lost

Hello,
You mention that you send a string to the microprocessor that tells it how many bytes to send. Instead of requesting 512 bytes, try reading 10 times and only requesting about 50 bytes at a time.
If that doesn�t help, try directly communicating with your microprocessor through HyperTerminal. If you are not on a Windows system, please let me know. Also, if you are using an NI serial board instead of your computer�s serial port, let me know.
In Windows XP, go to Start, Programs, Accessories, Communications, and select HyperTerminal.
Enter a name for the connection and click OK.
In the next pop-up dialog, choose the COM port you are using to communicate with your device and click OK.
In the final pop
-up dialog, set the communication settings for communicating with your device.
Type the same commands you sent through LabVIEW and observe if you can receive the first 54 bytes you mention. Also observe if data is returned from your 512 byte request or if HyperTerminal just waits.
If you do not receive the 512 byte request through HyperTerminal, your microprocessor is unable to communicate with your computer at a low level. LabVIEW uses the same Windows DLLs as HyperTerminal for serial communication. Double check the instrument user manual for any additional information that may be necessary to communicate.
Please let me know the results from the above test in HyperTerminal. We can then proceed from there.

Logicboard fried each time mba goes into sleep with external screen attached

I got new Mba 13". Plugged in my Phillips 24" screen as usual. Went away for an hour or so. Come back, and MBA doesn't wake up from sleep anymore. It's just dead, no light etc. I've tried all methods described here.
Brought it to service centre, they tell me logic board chip set is completely blown. So they replace to new logic board. Two days later, excactly same problem. When I put it to sleep without external screen, it seems fine. But once I've external screen attached. I've put it even manually to sleep. I only heard a small "flop" sound. And then again. MBA is dead.
So same thing. Brought to service center, they check. Again logic board fried. Also they told me that a lot of customers have same problem. Some ppl even replace logic board for four times!!!
Come on apple? Seriously? Whats going on here? Anybody have same problem and found solution? (except not putting it to sleep and contiously repair logic board).

Just an update on my situation... My 2nd logic board fried after about 5 days of use. Its been in the shop now for about 3 weeks waiting for another logic board as well as the USB daughterboards. Not sure how they determined that they needed to be replaced - I think they're just guessing at this point.
When you guys had your boards fried, did you have anything plugged into USB? I have a USB hub plugged in, and the hub has a hard disk, and logitech camera attached. Its been plugged in during each failure along w/ my monitor (a 22inch LG).
At this point I have no faith that the repairs will fix this. I've replaced my power strip, and will replace my USB hub next, but I just don't believe anything external is causing this, as I'm using all the same components with another laptop w/o any issues.
This next repair is my 3rd repair attempt, and my machine has been unusable since December 6th, 2011. Apple better replace it if it fails again. Nothing like buying the top of the line machine and having it in the shop for half as long as I've owned it. Apple's handing of this situation has been extremely poor, and as a first time mac owner, all I can say is I am not impressed.

Computer goes into random sleep and won't wake!

This all started over a year ago, but I no longer remember what started it. After downloading an apple update my computer no longer goes into sleep mode on it's own. I have to manually put it to sleep. I tried every solution recommended...resetting everything, changing things in terminal, etc. I used a sleep assist program for a while but then I removed it b/c it was creating other issues. I finally just got used to doing it manually and lived with it.
Well, about 6mo ago (I cannot figure out why it started happening) my computer would just randomly go into a hard sleep mode. The screen goes black but I can still hear the computer running. NOTHING wakes it up. I have to shut down the computer holding the power button and then turn it back on. There seems to be no ill effects and I cannot figure out what is triggering it. I downloaded a cpu temperature program thinking that was it but it stays generally under 40C. It usually just happens while surfing the internet with only 1 or 2 tabs open. I generally only keep 3 programs running at a time (firefox, mail, itunes). It is totally random as I can go weeks without it happening but then yesterday it happened 4x in one day.
Help, I will try anything! Thanks

chic,
This could be caused by a dead PMU battery. This is from the service manual:
"Logic Board Battery
Important: Apple highly recommends removing the battery when handling the logic board. Make sure to use proper ESD protection when handling modules.
The battery on the logic board controls the stored system settings, such as date and time. It is only necessary to test the battery when you can’t power on the computer, or the date and time are
reset every time the AC power is removed.
The battery is also used to power the PMU chip (because the PMU chip keeps time and must always be running) when the computer is unplugged from the wall (AC power). The PMU is very
sensitive and touching any circuitry that is connected to the PMU can cause it to crash. If the PMU crashes, the battery life goes from about five years to about two days if the PMU is not reset. Once the battery goes dead, the PMU will reset the time and date every time the AC power is removed. To fix this situation, replace the battery and reset the PMU (refer to “Resetting the
PMU on the Logic Board” mentioned earlier in this chapter).
If the computer has a “No Power” situation, check the battery before replacing modules.
Testing the Battery
1. Remove the user access door on the bottom of the computer.
2. Locate the battery test point.
3. With the computer powered off, measure the battery voltage. Does the battery measure at least +3.5v?
If no, replace the battery and reset the PMU. If the battery measures +3.5v or higher, reinstall the battery and reset the PMU as above."
The battery test point is the lone one to the left and the ground point is just to the right of it.
