MBP Goes Into Sleep Mode w/o permission.

I am trying to download a larger file and I leave my computer for a few hours only to come back to the MBP in sleep mode and has shut down all the programs I was running. I set the energy saver preferences to never fall to sleep when its inactive however it still goes to sleep. How do I fix this?
Thank you.

Got the exact same problem here - I have it plugged into power and my on-power setting says "never sleep" and yet keeps trying to go to sleep (actually I think it is shutdown) when I leave it alone for a hour or two. Most of the time I have stuff running that it can't close automatically so I come back to a window full off dialogs asking for quit confirmation.
Very irritating - is my Mac just trying to be green? Is it somehow thinking its in battery mode? Is there some more obscure setting that will prevent this?
Or is it just a bug...

How can I select shutdown & close the display w/o going into sleep mode?

I have learned to wait untill the MBP full shuts down before closing the display. In the past I have pressed shutdown closed the display only to find out later the MBP goes into sleep mode before fully shuting down. When I reopen the display the computer finishes the shutdown process or worse the battery is dead.
I would like to select shut down, close the display and walk away while the computer completes the shutdown process.
Is there any setup options or apps. that will allow this?
Thanks, Joe

Well hello there, and welcome to Macintosh.
Unfortunately you can't change anything to stop this from happening. The shutdwn process goes about its business killing processes and applications that have been running. The sleep process interrupts ALL business going on in the OS, and puts the machine into low power mode, as it is not aware of the nature of the running processes (in this case, the shutdown process), knowing only that they must be slept and the machine dropped into sleep mode. You gotta wait it out before you close the lid.
I would suggest sending a message in OS X feedback requesting this as a feature!

Mac Tower Pro 10.8.5 keeps going into sleep mode

Purchased from Apple, refurbished 2012 Mac Tower Pro. At the same time, purchased a new Dell U2713HM, 27" monitor.
Have been operating on this new system since about the first week of December 2013.
Issue:
The computer has constantly gone into sleep mode after a few minutes of no activity. I can have iTunes radio playing, but the system still goes into sleep mode. As I am typing and moving the curser, the machine stays awake.
This has caused much frustration because when it goes into auto sleep mode, it quits all programs that I am in, and when it does this, I lose all the work I had accomplished. It litterally closes everything and goes to sleep in about 2-3 minutes of no activity.
BTW: the computer and monitor have all its new OEM cables that came in the box, when I purchased the units.
Solutions attempted:
System Preferences — Energy Saver: computer sleep and display sleep set to "never" and unclicked the box "Put hard disks to sleep when possible."
Dell settings: Turned off all energy savers.
Results:
Nothing. Problem persists.

I apologize for the angst. The problem has cost too much money in lost time and material because when it would automatically shut down after a few minutes, all my work was lost.
I misunderstood the terms of the warranty. Thank you for your input and patience. Much appreciated. For the benefit of others that experience this with a new Mac that auto shuts down. Check the following:
1. Go to System Preferences.
2. Click on Security and Privacy.
3. Click on Advanced (bottom right corner)
4. If the first line is checked (Log out after 5 minutes of inactivity); uncheck it and then click OK button.
5. Be sure to click the lock before existing Security and Privacy.
Now the machine will cease shutting down programs to go into sleep mode as soon as machine is inactive for a few minutes.

Early 2008 iMac (8,1) randomly goes into sleep mode

Hey,
My early 2008 iMac (8,1) on 10.8.2 goes into sleep mode by itself. I've played around in Energy Saver, tried resetting SMC, NVRAM, replaced HDD, reformatted HDD, installed smcFanControl, reinstalled Snow Leopard, Lion, Mountain Lion. None of that worked. Took it to the Genius bar, performed some diagnostics tests and they said everything worked properly. Does anybody have the same problem? I can still use the computer for general computer use (light web surfing and e-mailing), but it seems to go into sleep mode when I have a lot of applications open and especially when watching videos. I've tried researching this problem, but I've haven't found a definitive answer. Right now, the Genius that I've been talking to thinks it may be the RAM. I'm waiting on new shipments of test RAM to arrive at the Apple Store for him to properly diagnose.
Thanks,
Jason
iMac (8,1)
2.8 GHz Intel Core 2 Duo
2x2 GB 800 MHz DDR2 SDRAM
ATI Radeon HD 2600 Pro 256 MB
1TB 7200 RPM SATA ST1000DM003-1CH162
If you want to read the whole time line, I've included it here. I apologize for it being so long.
At first I was running Lion (10.7.5) and the computer would enter sleep mode whenever I was doing anything with video. For example, watching YouTube videos and chatting on FaceTime. And funny enough, I distinctly remember watching a bunch of movies with VLC and the computer did not go to sleep (Although, this is not true anymore). I could wake the computer up and use it, however within a few minutes the computer would re-enter sleep mode. The computer seemed fine and I could access all of my files. Tried resetting SMC and it did not resolve the issue.
I made a Genius appointment to see if they were familiar with the issue. The iMac passed the in-store diagnostics test; it said all the components were functioning properly. He told me to bring it home to do a fresh re-install of my OS and then run my computer to see if the problem persisted. I took it home and reformatted my HDD with a 35-pass erase, re-installed Snow Leopard (10.6.8) and declined to transfer any backups from Time Machine. I was using a fresh system and sure enough, the problem persited. Tried doing the same thing again but with Lion (10.7.5) and still no luck. So I made another appointment and it passed the in-store diagnostics test again. I let them keep the computer for a 24-hour diagnostics test. They told me they would diagnose my computer with the OS on my HDD as well as a copy of OS that the Apple store deemed 'good' on an external HDD. The Genius called me and told me that my HDD failed their 24-hour diagnostics test and recommended I replace it. I initially had a 750 GB HDD, and the Apple Store could only offer me a 500 GB HDD ($200). I opted to take my computer to Carbon Computing, an authorized dealer in Toronto, to have a 1 TB Seagate HDD ($170) installed with no OS on it. I brought it home, performed another 35-pass erase and installed Snow Leopard. Problem still persisted. Repeated with Lion, still unsuccessful. Looking back, I was so excited that I just had to replace the HDD to fix the problem, I forgot to ask the guy if he could recreate the issue.
I began to suspect that it was a heating issue. So I installed Temperature Monitor and smcFanControl, and cleaned the fans as much as I could without taking the computer apart. Without smcFC on I tried to recreate the problem and I noticed that the Power Supply Position 1 reached 95 degrees Celsius, and Graphics Processor Temperature Diode reached 97 degrees Celsius before entering sleep mode. I don't know much about temperature sensors and what they monitor specifically, and so I couldn't draw any conclusions from that data. I turned on smcFC and cranked the optical drive speed to 2000 RPM, HDD to 3000, and CPU to 3000. The computer still went to sleep but the temperatures were below 90 degrees Celsius before entering sleep mode. I've tried researching here and on the internet about normal operating temperature ranges of iMacs and generally found that most do reached that temperature but they do not go to sleep mode.
Then I thought it may be a problem with Lion so I upgraded to Mountain Lion. The issue still persisted. Tried resetting SMC and NVRAM, did not resolve issue.
I called the same Apple Store explaining to them that their recommendation of replacing the HDD did not resolve the issue. They told me to bring it in and have them check it out again. I went through the same process I did before; the iMac passed all of their diagnostic tests. The Genius told me this time he will test out the RAM. He called me and told me that he could replicate the problem and so he proceeded to put in a stick of 'good' Apple RAM, but the computer would not work. He said the 'good' Apple RAM was damaged, either before or in the process of putting it in. He plugged in my old stick of RAM and the computer worked. He tried to recreate the problem and claimed that the computer ran for over 24 hours with an existing movie on my HDD playing and it did not go to sleep mode. However, once I brought it home I played the same movie right away and it turned off 17 minutes into the movie. Tried resetting SMC and NVRAM again, ran the movie again, still went to sleep.
And that's the story for now...

Now to find out WHY it does it at home only. How hot is it at home? Have you checked the AC current/voltage at home?
Well they were able to replicate the issue at the Apple Store the second time I left my computer there. Anyway, we don't have any heating on at my house at the moment. It's usually from around 20-23 degrees Celsius (72-75 F). Temperature Monitor says ambient temperature is 30 degree C though...
I'm not really sure how to check the AC current/voltage at home, but my computer worked before I moved it. So I'm not sure if that is the issue.
I normally only have speakers set up to my computer and a wired keyboard. The speakers are powered separately. I would assume that at the Apple Store only the power cord and wired keyboard are connected.
What is the Power Supply Position? And what does it do?
Thanks for your help!

HP Officejet 4620 All-in-One Loses Connection to Wireless Network When It Goes Into Sleep Mode

My HP 4620 All-In-One wireless printer works fine until it goes into sleep mode. Once it goes into sleep mode, it doesn't wake up if a print job is sent to it. If I wake it up manually by pressing the blinking on/off button, it still doesn't print. If I completely turn it off and then on again, the print job that was queued on my computer will start printing, but that's a huge pain and waste of time nearly every time I want to print. I've installed all available updates. I also assigned a static IP address in an effort to correct this but nothing helps. I see that others have complained about this problem, but I do not see that anyone has had success resolving this. My operating system is Windows Vista. I use a Link-Sys Wireless G Router. Thanks.
This question was solved.
View Solution.

so I have called HP tech support 12 times over the last 6 weeks and still my HP Officejet 4620 loses connection overnight. Of course becasue it was a birthday present I spent more time than I normally would have on this issue. While the tech are very polite they have not fixed my problem and now it is too late to return printer to store. This is a lot of money wasted and I think they need to admit this is a bug in this printer and resolve the problem!!!!!

IPhone 3gs wont turn back on once it goes into sleep mode!

2 days ago my iPhone 3gs (OS 6.0.1) has gone completely wacko on me and i'm completely frustrated! I have my phone set to have the screen shut off after 5 minutes. Usually, to just reaccess the phone I just simply hit the home button. Now, if I let it go into sleep mode, the phone WILL NOT come back on! I went online and did some research, and it suggested holding the home button and the sleep button for 10 seconds to get it to come back on. It works most times, but sometimes it takes a few tries to get it to come back on, and when it does come back on it takes forever to load up. But the whole thing happens all over again when it goes into sleep mode. My phone is fine as long as I set it to never go into sleep mode, but it is killing my battery. I need to be able to put it into sleep mode as I have to be able to go all day without charging it at my job. PLEASE help...I don't know what's going on with it. I have never done anything to it (jailbreaking, illegal stuff, etc.) and I do all the updates that it asks to do.
Please please help!
Jennifer.

If you actually see a "6" error code, here's what it means. Disable your anti-virus and/or firewall.

Late 2012 Mac mini with OSX 10.8.2 has started shutting down instead of going into sleep mode.

Sometime in the last week or so my mac mini has started going into full shut down instead of sleep mode.
I have tried checking and unchecking energy saver boxes but haven't found anything which will get me back to where I used to be - and I haven't knowingly changed anything to make this happen.- maybe an OS update caused it?
The machine will fire up with a tablet click rather than needing the reset button to be pushed so clearly the machine is sort of halfway between sleep and full 'off'. Most frustrating as one of the key issues for me in getting this my first mac was its easy sleep and super quick fire up compared to windows.
Any help appreciated
Oh yes I just remembered that I did just install 2 8gb of crucial RAM (to replace the supplied 2 2gb but surely that can't have anything to do with it - can it)?

Adding to my first post I can now advise that when the mac goes into sleep mode the light on the front stays on (it does not pulse so clearly it is not really sleeping).
When i click the tablet / keyboard this is actually what triggers the mac to reboot
I have tried resetting the SMC as per the following link to no avail

Streaming audio from my IPAD to my Apple TV from Rhapsody application. when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode.

I am Streaming audio from my IPAD to my Apple TV from Rhapsody application. when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode. I am using the Optical Out from the Apple TV to my receiver, the Apple TV is hard Wired to the Network, the IPAD is Wirelessly attached to the network (it continues to play the Audio Stream). When the Apple TV is turned back on it resumes playing once I manual select it for output from the IPAD. All device are on current releases of software. I have no Video hooked up to the Apple TV. How do I correct this?

Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

24" imac goes into sleep mode and lights on circuit flicker

Hi -
I have a 24" imac and have found that when the display goes into sleep mode the lights on the circuit flicker.
I have searched the web and other users have complained of the same issue with no resolution.
Here is a similiar post - https://discussions.apple.com/thread/2606099?start=0&tstart=0.      The resolution is probably you need to get the iMac serviced, what i'm wondering is what is the problem in the imac that is causing the issue.    Is this a defect?
Before anyone questions the circuitry in my house here is what I have verified.
An electrician has come and verified the electric panel is good and all circuit breakers are good.   All circuits in my house are copper, no aluminum.
I can plug the iMac into any circuit and the problem starts right when the Imac's display goes to sleep.     I have owned the iMac for approximately 5 months now (bought it used) and the problem started about a month ago.
Assuming this has to be serviced I dread to wonder the price .
Thanks for anyones help.

The sleep timeout has nothing to do with disk activity. It's based on user input, although some background processes can pre-empt it. If you don't want the machine to sleep automatically, disable automatic sleep in the Energy Saver preference pane.

Macbook spontaneously goes into sleep mode and screen off mode

Hi. My Macbook spontaneously goes into sleep mode and screen off mode with varying time between each instance. It usually goes for a few minutes or even hours without doing it and then will go through periods of fluctuation between the modes. I believe this to have started with a minor orange juice accident rather than it being anything software related.
Any ideas as to how I might rectify the problem? Thanks very much in advance,
Danny

When you say it goes into sleep mode ...do you mean you actually see the white pulsing light?
It may be that there is an application running (perhaps in the background) that is keeping your book awake. Printer software sometimes does this for example ...try logging out and seeing if it sleeps like that. If it does, then it very well may be a background process running.
You may find some items in System Preferences/Accounts/Login Items that may be the culprit.

Apple tv loses home sharing when my computer goes into sleep mode

Just recently, my Apple TV says that home sharing is off when my computer goes into sleep mode. It never used to do that - any suggestions?

I have the same problem here. Always back-ed up with Time Machine (OSX 10.9 Mavericks) to Western Digital drives. MyBooks, MyPassport 1TB (USB 3.0), all works fine. Time Machine is actually doing back-ups overnight. Since I got this new 2TB MyPassport Ultra USB 3.0 it's working perfect during days, but every morning when I wake up the MacBook from sleep, I get this annoying error:
Time Machine couldn’t complete the backup to “MyPassportUltra”.
Unable to complete backup. An error occurred while creating the backup folder.
Latest successful backup: Today, 02:27 am
I'm also not able to write anything to that drive, or unmount it. It stil shows up in Finder, and I'm able to read all the data perfectly fine. When I do a Disk Utility Verify Disk directly after, I get this:
Checking volume
disk3s2: Scan for Volume Headers
Invalid Volume Header @ 0: I/O error
Invalid Volume Header @ 2000021315072: I/O error
disk3s2 is not a CoreStorage volume
Error: This disk needs to be repaired. Click Repair Disk.
I don't click Repair Disk, as this will probably screw up my partition. Instead, I have to unplug the USB cable (which is bad for the drive, there's no time to park the drive's heads) and plug it in again. After clicking Backup Now, Time Machine immediately starts backing up, and the drive works fine the rest of the day.
I contacted WD Support, and they are sending me a booster USB cable. As System Information reports, the drive receives enough power though:
Current Available (mA): 900
Current Required (mA): 224
Unfortunately there's no firmware update for this drive, which will probably fix this. See this topic: https://discussions.apple.com/thread/4196704.

RBDAPP01 going into SLEEP Mode and Idocs still in 64 status

Hey all,
I have a Inbound Idoc interface which is being processed using RBDAPP01 Program. The Issue I am facing is that the job running the rbdapp01 program goes into sleep mode even though there are idocs present in 64 status. I tried to debug the work process using SM66 but it does not open any debugging window although it says debugging started. If I cancel the Job and run it again it processes those Idocs Any input on how one can resolve this issue?
Thanks.

Hi Aparna,
Here is extract from SAP material on running RBDAPP01 transaction and possible reasons for delay in processing. HOpe this can help you.
To automate the treatment of IDocs, you must run the ABAP program RBDAPP01 (transaction BD20) in job. This program has a very good option for parallel processing which can reduce a lot the time required for treatment. However use it carefully and make sure you set a packetsize high enough to avoid that your SAP system be overwhelm by demands for available dialog tasks (don't forget one dialog task is monopolized per IDocs packed to treat).
Best Regards,
Krishna

My new nano keeps going into sleep mode every copy of minutes while music is playing. I can't figure out how to stop this. The user guide isn't too helpful. Any ideas?

This is usually a sign that your iPod's headphones are not plugged in all the way. Make sure that you cannot see any of the silver still showing from the headphone's plug. You should hear a sort of popping/clicking noise when inserting the headphones letting you know that they have been fully seated.

Mac Pro randomly goes into sleep mode

My (mid 2010) Mac Pro, OS X.6.8, randomly goes into sleep mode and I can't wake it, have to power it off and reboot. Just started to the best of my knowledge Friday (Jan 6, 2012) I've had it happen surfing the web in Safari, while working on an illustration in Adobe Illustrator, while running Apple Hardware Test, using 23" LCD connected by HDMI and DVI-D, Disconnected monitor and connected 12" Cintiq (LCD Tablet).
The monitor goes black, says "there's no signal coming from your computer", none of the keys will wake it. I have to hold down the power button until it turns off then power it back up. The time between the sleeps varies, 38min, 1hr 34min, 5min, 2hr 17min, 12min, etc. I disconnected everything (except keyboard, mouse, monitor) still the same. Opened and removed the ATI Radeon HD 5870, and noticed the PRAM battery, replaced it with a new one, thought that fixed it, worked for a long time then it happened again.
Tried Apple Hardware Tester again, it said everything is fine, ran it again an error popped up: 4SNS/1/40000000:Te1S-99.364, wrote it down then it slept.

The next time this happens open your mac and see if there is still a fan running. If so you are not sleeping, you are in a thermal cutoff. Keep you mac cover off.
Now reboot as you always do. Take a look at the fan in your 5870. Is it spinning? If so, try to keep an eye on it and see if you can "catch" it not spinning.
When the fan doesn't start, or if it does then stops, the card will overheat and the machine will go into thermal cutoff. The amount of time is variable.
I speak from experience. I am currently on my third 5870 video card. Both the previous two had this fan problem. The only wrinkle in my theory for you is that I wouldn't expect more that, say, 15 minutes of up time at the most, not hours like you got. But it may be that your card is starting ok, but stops sometime later. I chalk it up to the lousy fans Nvidia uses in the 5x70 cards.
FWIW, if you happen to catch the fan stopped before the machine goes into thermal cutoff you can give it a little nudge with your finger to get it going again.
I recommend one of the various temperature monitors. I use iStat Menus and display some key temps in my menu bar. Of course after going through two of these cards I am a bit paranoid!
Some other temperature monitors:
iStat Pro
Temperature Monitor
Hardware Monitor
Note, after typing all this I also realized you got a AHT 4SNS error. I would run AHT again to see if you get that error again. If so that means "Check Main Logic Board" and you may have a more serious hardware problem than just a video card! So my other recommendation is that when you machine fails again look inside for any lit diagnostic leds. There's some near the dimms but there are others on the board as well.

When the system goes into sleep mode it keeps making a beeping noise. The system is shut down by holding the button in

When the system goes into sleep mode it keeps making a beeping noise. The system is shut down by holding the button in
and will then boot up again without any errors.
I Have replace RAMS, Motherboard and Power Supply. I have check the Bio's and Power setting on the unit. there is no place to cause this issue.
Please help
PC Power Tech

Syamak,
You didn’t specify where the beeping noise is coming from.
If it’s coming through your speakers, you could try to update your audio drivers since it’s possible they’re incorrectly sending a signal to the speakers as the audio chipset enters standby.
If the noise is coming from the motherboard, you’ll need to take a closer look at your system’s configuration or contact the manufacturer.
I hope this helps.
