Randomly sleeps

Running rMBP on 10.9.2, my computer will completely randomly go to sleep. The screen will just go black and keyboard lights turn off, then I have to wait 10 or so seconds to turn back on. Why?

A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--
(username is your name or System Administrators name)
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.11 Combo update (PPC not for Intel Macs). Others reading, download the combo update that applies to you!

Macbook Pro Early 2009 Randomly Sleeps / Black Screen While In use

My macbook pro Early 2009, randomly goes to sleep while I am using the computer, I first noticed it occuring while I was using the mini display adapter to a computer monitor, and using a second monitor and watching a movie, the screen would go blank and I would have to wake it from sleep for it to come back on, sometimes closing the lid, sometimes pressing the trackpad, or keyboard to get it to work again, sometimes it would go back to sleep within 1 minute of waking.
I assume the problem could have been from perhaps water damage, as I recently used a wet paper towel to clean my keyboard, and perhaps the paper towel was a little to moist, not overly but perhaps just enough to damage the sleep sensor. I am still unsure where that is located, the only other problem I have noticed with the computer is my [battery service indicator] notification has been on for the last year, but since I never used the battery, I always have it plugged in at the desk I never bothered getting it serviced. So
I'm assuming its the Sleep Sensor? but here is what I hace done, just to make sure its not software. I was orignaly running 10.8, and after being frustrated while watching a movie and having my computer sleep every 2 minutes, I whipped my hardrive, put 10.9 developers preview on a usb and installed that.
On 10.9 I can swipe with 3 fingers on the trackpad and the display appears but if i let go of the swipe it goes back to black screen.
I can see Icons like, brightness, and sound, when adjusting the levels, but screen is black behind the icons
The mouse pointer cursor is visible but the screen is black
I can move the mouse and hear system sounds, but screen is black. Now I have to actually restart the computer because It seems like I cannot wake it up at all.
So I formatted the hardrive again and
I tried reinstalling Leopard OSX , as that was the disc that came with the mac,
but have Same problems in 10.5, 10.6, 10.7, 10.8 I upgraged to developer 10.9 to see if the problem would fix, but still occurs.
I ran hardware diagnostic off the leopard disc 2, by pressing the D key on startup with disc in drive, extended hardware test reported no problems.
I SMC reset and PRAM reset, [control]+[option]+[shift]+[powerbutton] while computer is turned off with power plugged in
and after that failed I tried pressing [Option]+[Command]+[P]+[R] before startup chime, chime repeat let go of keys and it booted normally.
Then computer randomly sleeps while in use, while using safari and it has happened 3 times within 2 minutes of typing this.
I have downloaded a program called InsomniaX, and activated the disable sleep for Lid and Idle, but now the screen will randomly just go black and then turn back on, sometimes it will just black screen for 10 seconds and come back on, altho after changing some more of the settings It appears to be not as frequent. It hasen't gone to sleep since writing this entire paragraph, so thats a good sign.
I was going to take it into the apple store, and have them run diagnostics, but I hate going into those stores because of all the iphone people, crowding the place.
Well my screen just blacked and came back within 10 seconds on while I typing this line so InsomniaX didn't work. I hope having the sleep sensor replaced isn't too expensive, or if my model even has such a sensor.
I read on another topic that this problem can be replicated by users putting a magnet on their laptop, something like an iphone or a money clip or even having one of these in their pocket while using the macbook on their lap. I have not had anything near the computer, so I have a different problem.
Just thought Id document this, will let you know what happens after the diagnostic, I tried apple support, and they said I did more than they would have done, so he couldn't really tell me anything besides take it into genius bar, (is that what its still called) and have them run diagnostic, [note its different than the hardware test on the cd]
and my computer screen goes black again, wow..

Hi pictureswithPS, welcome to Apple Discussions!
1. I have an original late-2008 unibody MBP that was purchased a week after the introduction. I have never had a single "black screen of death" ever, and I do some gaming under OS X on my machine. The heat issues are, in my humble opinion, greatly exaggerated. Does the machine get warm? Yes. However, any computer with this much power in this thin of an enclosure is going to get warm. Mine has never crashed, frozen, black screened, etc. once.
2. I don't think PS is particularly intensive on the graphics card. It may use the graphics card, yes, but I don't think it will be quite as intensive as a 3D modeling application or 3D games. I would doubt you would ever run into problems anyway.
3. Lastly I am aware that their are tools to manage fan speed behavior - as a workaround to cool down temperatures. Using this software would it void the warranty that is provided by Apple?
No, it wouldn't likely void the warranty. However, if your fans die prematurely as a result of running them at high speeds for extended periods of time, I doubt Apple would be especially happy about replacing them. I do not use any 3rd party tools to manage my fans, and never will. It is simply not necessary.

Random sleep mode after Mountain Lion install

Hello, I have a MacBook air 11" late 2011.
after installing Mountain Lion I get random sleep modes, usually right after a waking up the computer.
that has never happened before so I assume that it is a sotware issue.
I do not have a hot corner for sleep (have checked)
anybody else has the same problem

It goes to sleep sometimes right after I wake up the computer ..
wake up , 3-5 seconds .. I click somewhere.. it goes to sleep
any downsides of resetting the PRAM and SMC

Display randomly sleep at times?

At odd times, the display and keyboard backlight of my Macbook randomly sleep. The computer continues to wake after I click the trackpad, or press a few keys. The display sleep is not as a result of inactivity, while I am using it, typing, surfing or otherwise, it will sleep. It sometimes acts as a flicker because I am typing as it sleeps and wakes. The same thing can be reproduced by pressing the controlshifteject buttons.
Do I need my logic board replaced? Should I just return it?

Apparently, the issue deals with the Logic board, and the motion sensor. I'm sure its repairable, unfortunately, Apple has lost me as a customer. I found that the audio device in my new Macs powersaves, making an annoying poping sound, that can be found here > http://discussions.apple.com/thread.jspa?threadID=2108844&tstart=0 .
Other than that, for anyone reading this, the "display sleeps while im typing" glich is a hardware issue.

W520 random sleeping and black screens - videos of issue attached

Btw my mobo,cpu,memory i believe were all replaced last time i took it in with this issue...
Still getting it consistantly:
Random Black Screens and Random Sleeping:
www.youtube.com/watch?v=AvWl9ck26xI
Black Screen:
www.youtube.com/watch?v=7A3NqnC80iU
I thought before maybe its Bluetooth related as sometimes when screen would turn black and then come back, I would get a 'Bluetooth Device Not Discoverable'. So turned off Bluetooth in the BIOS, but still having display/sleep issues.
I removed hte Lenovo Power Manager/PM Driver, and turned off sleeping in the Windows power settings (in every setting including if Low Battery Action). Any ideas?
I just upgraded to a 3 year warranty (the more expensive one), should i just ask to replace mobo/cpu/memory again or will Lenovo actually test it for other issues?
Thanks,
Ari
Solved!
Go to Solution.

Well my issue wasn't an external monitor... it would goto sleep by itself when Im trying to write code/programming... then randomly wake and go back to sleep up constantly ruining workflow (or wait a few hours Im sleeping at odd times in the morning lol). or the monitor would turn black suddenly. I think I tested via external monitor but didn't matter what result was, the random sleeping issues indicated a larger issue.
It was a crimped connector the 1st time it went back to Lenovo. the past 4/5 times its gone back i think they are stumped. For me, Im honestly not sure... it might be the OS is on a mSATA instead of the regular hard drive and Windows doesnt know how to handle that hardware.
Their newer W540 manual seems to indicate do an OS on mSATA at your expense.
Do you have an mSATA OS? Anyway, thats a very small chance. not sure.

Random sleeping, sporatic battery

Well maybe not random sleeping....
So I have been having some battery issues lately, and as such I have been re-calibrating the battery often. Right when I started having the battery issues, i started having the following problem:
Usually, when my battery gets at about 10%, I get a warning that lets me know that I need to plug in my macbook before it dies. Lately, I get no warning and it goes to sleep at around 20-30%
Any ideas on what is going on

Random Sleep/Shutdown

As of recent my mini has started to randomly sleep and shutdown for no apparent reason. I have disabled all sleep options in energy savings, I have rebooted, I've removed all hardware, and still I get a shutdown or sleep every 20 seconds or so. I have no idea what to do.
Any ideas/solutions?

I had this same problem today, and I found that if the cable wire has broken away from it's solder that the fan likes to simulate a button press. Since you have to buy the entire bottom frame for the modular button I found a temporary solution that will work for now.
However, I am still having the same problem, so I am going to check the switch again, but something is fishy.

G5 Quad, fans @ full blast & random sleeping..

I'm using a PowerMac G5 Quad, 2.5ghz, running OS x 10.5.8 I have a problem with random sleeping,
(the Mac, not me LOL). Sometimes it will go for days, run all night, with no problems.
Then it suddenly goes to sleep. It's not overheating, I've cleaned it out regularly & have temp monitor running.
It has done it within minutes of starting up. After it goes to sleep it can be woken with a mouse click of keyboard stroke,
and 9/10 times everything is where it left off. It has crashed, but comes back OK.
I have read a lot of stuff about firmware updates, but not sure wether to proceed.
Another symptom is constantly noisy fans.
How can I tell which firmware is running on the machine now?
Can anybody advise a course of action?

Still have fans @full blast at all times.
What controls the fans? Is there somthing else I can re-load or reset?
There's always the SMU reset: http://support.apple.com/kb/HT1436
The fans are controlled via the SMU, which has a watchdog timer running which is reset when control comes from the CPU running the system piece that monitors the thermal state of the machine. That is why, when the system tanks, the fans will firewall as a safety measure.

G5 Dual 2.5 Randomly Sleeps

All of a sudden my G5 dual 2.5 has started putting itself to sleep randomly and frequently (minutes between sleep). I can wake it up fine but I can't get any work done. I'm running 10.3.9. I don't have any of the energy saver settings set to sleep (computer, hard drive or monitor) and I never have. It runs 24/7. The only software that has changed recently is an iTunes upgrade to 7.6.2.
I disconnected everything except ethernet, monitor and the USB keyboard and mouse. I can get it to run fine if I remove the air deflector. I worked on it for about 5 hours today with the deflector off and had no problems. I cannot see any signs of a coolant leak.
Although I'm certain it's a hardware problem. I tried running DiskWarrior from a special boot CD. It starts up fine from the CD and I can start DiskWarrior. But when it gets to step 6 (building replacement directory structure) it starts to go to sleep (all the fans stop and the monitor goes black). I hit the space bar and it wakes back up. The fans start up again and DiskWarrior continues. I've tried it twice with the same results. I never actually do the rebuild though because I'm afraid it will go to sleep and totally screw up the hard drive. The fact that the sleep problem exists even when running off the CD suggests that I have some sort of hardware problem doesn't it?

I disconnected the power over night and reset the PMU. Neither changed anything. Here's what looks to be a relevant section of the console log.

Slow start up & shut down, freezes randomly, sleep issues

My mother has an iMac Intel Core 2 Duo, 2.8 GHz, model iMac8,1, with 4 GB RAM, and a 300 GB hard drive. She uses this computer primarily for email and the internet, and some writing using Pages. So on her hard drive, only 22 GB is used, and the rest is free. She is on OS 10.6.8.
She originally had 2 GB RAM so I thought the lack of RAM was causing her issues. So I recently installed 4 GB RAM, but she's still having problems.
A few of the problems are:
• She'd be typing an email and the monitor will suddenly go black.
• Safari and Mail sometimes are really slow to load, and often we get the spinning beachball.
•   Random freezes, especially in Safari, Mail and Pages.
•   It takes a long time to go to sleep.
•   It takes a long time to start up and/or shut down.
When the computer freezes, she'd try to restart it, and when that fails, she'd try to manually shut it down by pressing and holding the power button. Sometimes that doesn't even work and she ends up unplugging it.
She still has the same issues, even with the 4 GB of RAM. Her iMac is 2.8 GHz but seems very slow to me (and my MacBook Pro is only 2.0 GHz!)
I ran the Tech Tool Deluxe that she has with the extended Apple Care, and everything passed. I was also concerned about the hard drive's S.M.A.R.T. status, but Disk Utility reported that the S.M.A.R.T. status was verified. I ran the Apple Hardware test in Extended Mode, and everything passed. I also reset the SMC too, along with the PRAM. And of course repaired permissions. PageOuts are zero, and was even zero before increasing the RAM from 2 GB to 4 GB.
I checked Console, and I did find a few weird items that came up often:
com.apple.print.FaxPrefs.Fax#lookup
/usr/bin/fax
So I deleted the first one, but was unable to find the second one to delete. I figured it was from my mother's old all-in-one HP which has since been replaced with an Epson, as it seemed to be looking for a fax number or something. I had hoped all my work along with the new RAM would solve the problems but they haven't.
Thank you in advance for any help and suggestions.

One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Extended random sleep problem

I've seen several threads here about PBs randomly turning off, and lots of tips to try to fix the problem. However, my PB randomly went to sleep but hasn't turned on for almost 12 hours. Before, it would wake up after 30 minutes at the most. I know its still asleep because the light is still pulsing, but I'm kind of stuck. It won't turn on, it won't shut down. Any ideas of what to do?

AJ,
You could be having the same problem I am experiencing and while it isn't fully solved, I am getting around it quite comfortably for the time being. If you go to a thread with my name called "sleeps and won't wake" on the same forum there's a description and web link to an alternative trackpad driver called Sidetrack which, if you install, stops the pb from sleeping at random. It costs nothing and has worked for me. I did upgrade to 10.4.3 in the hope that apple had fixed the problem and unistalled sidetrack but the problem began to reoccur. Worth a go.

Macbook Pro randomly sleeps or dies

I have a mid 2012 Macbook Pro Retina 2.3 GHz
The problem:
While using my macbook, the screen will randomly go blank like its gone to sleep. I then press the power button and get the red and black dead battery symbol on the screen. I plug in the charger and it comes back on normally but the battery will not be dead - its normally on between (25%-35%).
I have given my Macbook Pro into an Apple Store and an Authorised Repair Centre. Both of them refused to do anything because they couldn't replicate the problem. The Apple store ran a system health check in front of me and everything returned normal including the battery. I tried to explain that it happens randomly with no specific application running. It has happened most times when I'm browsing the internet using Chrome so I switched to safari and it still happened and once it happened when playing Football Manager 2015.
I have tried a clean install of OS X and resetting the SMC and PRAM, but none have made a difference. The problem occurred on both Mavericks and Yosemite.
(I still have my extended apple care.)
Any solutions?
Thanks

Random sleep while working without reason despite power settings always ON hibernation disabled.

For the last couple of weeks the computer started to go into sleep or hibernation mode, at random times, without warning message and no reason as the power settings have hibernation disabled and all other power options, including sleeping are set to "never", or always ON. Also it happens either 5 min after booting or an hour after, even when using applications and having open windows. The only way to get back to using the computer is to do a forced shut down from the power button and then reboot.
Computer has been working fine for years. I have Windows update running daily, updated antivirus and no registry issues. This is getting very annoying, please help with solutions or suggestions. Many thanks for your time.

Dropped Mac: Randomly Sleeps Now

I dropped my Macbook Pro and dented the right back corner. Now it randomly goes to sleep while I am using it. How can I fix this? Is there a sensor located there that puts it to sleep that I can disable? I am out of apple care warranty.
Thanks!

No there are no user accessible sensors, sounds like the closed lid sensor that induces sleep mode.
Visit an Apple store genius bar and have the techs test it to see what is causing it to think the lid is closed...they can tellyou what the cost would be to fix it.

Goes into random sleep mode...hard to start

My IMAC G5 will randomly go into sleep mode while I am in the middle of using it. Typically the fan noise increases and than it auto goes into a sleep mode. It also has issues starting. I have to press and hold the power button for it to kick on while also hitting keys on the keyboard to trigger it. Help!?

iMac model? There are four large families of iMac and each has different troubleshooting issues. This forum covers older ones made between 1998-2005.
What does "About this Mac" in your Apple menu say about your processor type?
