Macbook pro goes into sleep mode after few minutes and won't wake up

Since yesterday my MB pro suddenly goes in sleep mode while working and won't wake up. After reset the MB Pro goes into Sleepmode befor I get the log in screen. After resettin SMC and PRAM I can log in but after a few minutes, againg deep sleep. I'ts not a software isue I think because when I use my MB Pro's harddrive by firewire as the startup disk on an other macbook it works fine. anyone knows about this problem?

It sounds obvious but are you sure your power adapter is ok and the battery is charged. The behaviour sounds a lot like low battery sleep.
Press the check button on your battery pack - do you get plenty of lights?

HT4392 My macbook air goes to sleep mode after 2 minutes, how can I make this longer? It's frustrating trying to work.

Hello,
I am struggling to get my macbook air on a longer sleep mode, i have searched through the settings and trying putting the saver onto a longer time, however this does nothing. Now my macbook keeps going to skeep after two minutes and its really quite frustrating, can anyone help me?

Go to Apple menu / System Preferences / Energy Saver.
Change the settings for computer sleep and display sleep to what you want them to be.
Next - important step - reset the PRAM.
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Macbook Pro goes into sleep mode randomly

I have a Macbook Pro, early 2011 version running Mountain Lion. Sometimes, it doesnt matter what I am doing but it will be running fine and then out of no where the screen will go black. I assume it goes to sleep because the sleep light goes on. It take a couple minitues for it to "wake up," more than from a usual sleep. Is there something wrong with my computer? Is there a quick fix for it? Any help would be appreciated. Thanks

Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset:
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 its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

My Macbook Pro goes into sleep mode despite disabling it in Energy Center. It won't wake up without a hard reboot. Why?

I have a LaCie thunderbolt external storage device attached. All the reboots are of concern for this device. I've tried cntrl-option-eject to no avail. Only the power switch works.

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.

Mini goes into sleep mode after login on

I put my mini into sleep mode after logging out. Then, when I log back in, after a few seconds, it goes into sleep mode again. I have to re-awaken it.
This is not the way the computer should work.
Is this a configuration issue, any ideas????
I use Apple's bluetooth wireless keyboard and mouse combination.
Thanks

How do I stop my macbook from going into sleep mode while watching netflix

Hi can somebody give me a hand?

Open System Preferences > Energy Saver
Move the sliders for as long as needed to watch the movie.
Deselect: Put hard disks to sleep when possible
After watching the movie, in System Preferences > Energy Saver, rremember to click: Restore Defaults to save wear and tear on the hard drive.

IMac taking ten minutes to start up and sits at a blue screen for the most of the time. Also, when it goes into sleep mode I am unable to wake it up from it.

For the past few days now whenever I go to turn on my iMac it takes roughly ten or more minutes to boot up. For the portion of this time it sits on a blank blue screen. At first it comes up to a plain white screen which after about 30 seconds has the apple logo on it and the spinning circle for about a minute then to the blue screen, every time. Then, to top it off right when this started happening another problem began occurring. The computer is set to go into sleep mode after 15 minutes of no use. But, if it is in sleep mode for too long I am unable to get it out and I have to restart the entire computer, but if it is just for a few seconds into sleep or a minute I am able to get the screen to come back. I can still here the fan running and such so I don't know what is going on. I have searched through discussion after discussion. I have tried: repairing disks, repairing permissions, starting up in safe mode, and such. There has been no luck so far. I was wondering if anyone could offer insight into fixing at least one of these problems since my schooling relies on the computer.
By the way I this is an iMac 10.6.4 refurbished which we just bought about two weeks ago.
Thanks for any suggestions!

My iMac i7 quad was having the same symptoms with the blue screen and long startup times a couple of months ago. Apple Care told me to bring it in to the local Apple Store, and after some diagnostics, the hard drive required replacing. It took one day to replace the hard drive and my iMac is running great. I only had the iMac for about 12 months when the drive needed to be replaced. Not sure if that is your Mac's problem, but it was for mine.

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.

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.

My macbook boots up and only stays on for 30sec and goes into sleep mode

My macbook boots up and only stays on for 30sec and goes into sleep mode! Any suggestions as to why this might be happening? Thanks....

I assume you have checked your sleep settings in System Preferences>Energy saver
I also assume this has just happened recently and spontaneously, not after installing any particular hardware or software or you would probably have mentioned it...if anything new has been added recently, obviously just remove it!
It could be the battery - have your tried it just on mains? If it's a pre unibody MacBook try it without the battery at all. This could happen if you have a non-Apple (cheap Chinese) replacement battery.
Try NVRAM, PRAM & SMC resets (Google if you don't know how)
Try booting from the install media and repairing or reinstalling OS X. (Back up first!)
Just out of interest if you boot from a DVD or go into Open Firmware or Boot Select modes, does it still sleep after 30 seconds or is it just in OS X?

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.

What do I do if an iPod shuts down after going into sleep mode

My friends iPod keeps shutting down after it goes into sleep mode. I just fixed it up (restored it, had to dry it out after it fell into water) and now it does that. Everything else works fine but if I put it in sleep mode or put it into sleep mode it shuts down. How do I fix this because I've never seen this happen before.

Hey Tecmo_SB_Guy,
I would suggest you take a look at advanced power settings. It can seem like the notebook is turning off when it is actually just hibernating. You can set it to not hibernate.
1. Windows key + Q to open the Search Bar
2. Type "power"
3. Click Settings under the Search Bar
4. Select Power Options from the results on the left.
5. In Power Options, Click Change when the computer sleeps, on the left.
6. Set the Put the computer to sleep setting so that it fits your usage best.
7. Click Change advanced power settings, at the bottom.
8. Expand Sleep and expand Hibernate after. If you want you can change the hibernation setting to Never by typing "Never" into the minutes field. See attached picture. You can do this for battery and/or plugged in.
9. Click Apply to save changes.
If you don't already shut it down periodically, I would suggest shutting it down at least 2-3 times a week if you use it daily. Leaving the computer running continuously can shorten its lifespan. Hard drive failures and motherboard issues are seen much more often on machines that are left running constantly. Computers get bogged down and run slowly when the memory is full. Memory only clears out and resets itself when the computer is shut down. Here is a link explaining more about memory accumulation and hardware aging.
I hope these suggestions help! Please let me know if you have any questions

HP Envy shutting down after going into sleep mode

Hi. I'm not sure where to post this so I'll try it here.
My laptop shut downs automatically when it goes into sleep mode. Not right away when going into sleep mode. Maybe like an hour later after going into sleep mode.
I'm not sure it's overheating because it never shuts down while I'm actually using the laptop.
Do you guy have any idea how to fix this?
Product name and number: HP ENVY TouchSmart Sleekbook 4-1115dx
Operating System: Window 8
Error Message: None
Any changes to your system before problem occurred: No

MacBook goes into Sleep Mode w/o me telling it to

An iPod-like image pops onto my screen with "Zzzz" coming out of it. Then my computer goes into sleep mode.
This has happened a couple times. Once, I did not have it plugged in. The other time (just now), it was plugged in. Neither time was my battery even close to low power. Neither time did I come close to touching something that would put the Mac to sleep. I have checked my power settings, and they are all correct. For instance, I have the power/screen not shutting off when it is plugged in.
Any ideas???

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...
