PowerBook randomly sleeping

My computer goes to sleep whenever it wants to...and I can't wake it up, it wakes up on its on, it actually just shutoff while Im writing about it shutting off
if anyone knows how to fix this let me know
PowerBook   Mac OS X (10.4.4)  

Search within Discussions>PowerBook for "spontaneous sleep". This is not a new issue. After being made to jump through hoops by AppleCare (including erasing my hard drive and reinstalling system), we could find no solution.
I sent my PowerBook in to be fixed, but a "part" was not available so they sent me a new one. In other threads I remember some people getting new motherboards to solve the problem.
Good luck.

  • 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.

  • Powerbook randomly shuts down whilst asleep

    Hi there,
    I know there are a million topics on here about such faults but none of them were incredibly similar to similar to mine, so I've started a new one!!
    My problem is, just outside of Apple's 14 day no quibble return period my powerbook randomly turns off whilst asleep. There are no patterns to this, nor is it related to any system settings or anything. Sometimes I return back to my powerbook after 5 mins and it will be powered off completley, sometimes it can be upto 2 days. There really is no common factor in each occurance.
    My machine is a 15" G4 Powerbook 80GB HDD 512MB RAM and DL SuperDrive. Software update told me to do the battery firmware updater but I did this the day I got the machine, so I have no idea whether it did this before.
    I did buy it off the refurb store, so maybe this was the original fault for which it was returned in the first place. But my G5 is also a refurb unit and thats absolutely fine, so I have no issues with refurbed items!
    I was just wondering if anyone had a similar problem, or knew what the fault was. I think I'm going to take it to a repair centre and let them have a look at it, as its under warranty and all.
    Anyway, be great to hear from anyone who is in the same boat as me!!
    Cheers
    Powerbook G4 1.67 15" 80GB 512MB DL   Mac OS X (10.4.5)  

    Looking through the forum quite a few people have the same problem with the same machine, 1,67Ghz, no accident, i feel, maybe a design fault or a faulty batch.
    I have exactly the same model and exactly the same problem.
    Drives me nuts.1 out of 23 times and the computer shuts down completely after I closed the lid.
    I got my model already replaced for a new one and have exactly the same problem with the replacement.
    It is being examined at the moment at a service centre.
    Problem is that the fault only occures every now and then over a period from a day to a week.
    Please let me know if anyone has solved this

  • Powerbook g4 sleep problem

    Okay im having a problem with my powerbook g4 15in 1.67ghz recently I have replaced the top cover tht can be removed to access the logic board and other comments  of the powerbook. But after I had replaced tht cover the computer has not been able to go to sleep when the display is closed and you have to put to sleep by click the apple logo and then sleep also when you open the display of the laptop it does not automatically wake up you have to press the space bar to wake it up. Note I took the top cover from another powerbook g4 tht was an 15in an was 1.67 ghz.

    There is a sleep switch that may have been compromised during reassembly.

  • 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%

  • 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.

  • Powerbook randomly falls asleep

    Ever since installing 10.4.7, my 17", 1.67 GHz G4 randomly falls asleep. I red somewhere that in order to fix this i need to replace the case as it has something to do with a sensing bug in the hinge region of the case that senses whether the lid is closed or not. Anyone have any more information concerning this? Basically, I'm expecting to have to send it in for a hardware repair.

    Daniel, you might want to check this website I have put up. A lot of 15" PB owners have a nighmare problem with random sleep caused by a faulty trackpad temperature sensor. Let me know if your symptoms match ours...
    ... ie computer will sleep without warning and wont wake up without drastic measures... ie take out battery, remove power supply and wait for the catch light to die... replace battery, restart and then shut down again. Take out battery and hold down the power button for 10 sec. Replace battery, restart. This wipes the PMU memory and we can restart and reset our date etc etc.
    If you install the free s/ware Temperature Monitor, you can see if your trackpad is showing false high temperatures... if you check your system log you will see 'emergency overtemp signal causes system sleep" messages after a sleep event (refresh the log)
    Good luck and join up to my mail group if you have not found a cure by now.

  • 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?

    OK I,ve found my boot ROM version, It's 5.2.7f1 which is higher than any mentioned in any updates.
    I've zapped the P RAM and Reset the NV RAM...
    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.

  • Random sleep? is my powerbook narcoleptic?

    So my laptop has started to randomly go to sleep...usually while I"m using it, the screen will all of a sudden go black, and I have to press the space bar to wake it up again. No idea why this is happening....has anyone heard of this before? Have any suggestions about what to do? If it keeps happening I'll call Apple soon..i'm still under warranty (it's only a bit over ayear old)...but hopefully this isn't anything major. Any help/advice would be greatly appreciated. Thanks!

    Assuming it was the OS I am going to
    reload OSX from the disc and see what happens.
    I've tried doing an archive and install after running all sorts of utilities, but all that did was give me hours of "fun" spent getting all my apps to work again. It didn't solve the problem. The update could be related to your problem, but I just thought I'd tell you my experience. AppleCare told me to do the re-install even though I didn't think it would help. They wanted to try to rule out software as the culprit.
    Do you get the "Power Management received emergency overtemp signal" (see your system.log) from your trackpad sensor?
    The strange thing I haven't yet reported in my posts is that about a week later my trackpad tempurature showed 77 degrees F and has been stuck on that ever since. It hasn't moved even one degree for over a month. At least that's good because there is no overtemp warning and shutdown. I'm sure it still indicates a problem with the sensor and it would be wise to get it fixed.

  • Powerbook G4 Randomly Sleeps (and didn't wake up once)

    Greetings,
    Context: Clean install of 10.5 and moved all my files okay from 10.4.10 (yesterday). Machine is a 1.5Ghz Powerbook G4 w/ 2GB SDRAM. Running the machine closed with Dell 2007WFP monitor and the new Apple aluminum keyboard.
    Problem: My machine randomly goes into sleep mode without warning. After wiggling my mouse around for a couple rounds it comes back to life. I don't get it.
    It's not the screen saver or the power savings settings. I set it so that it never sleeps. Earlier today, I returned home from work to discover it had went to sleep, except I couldn't wake it up! or hard power down. I took out the battery, and the light was still pulsing as usual. I then pushed the power button again to finally shut it down, then power back up.
    Thoughts?

    Try this then:
    1) Try trashing these 2 .plist preferences and reboot. Reset your Energy Saver preferences.
    HD > Library > Preferences > SystemConfiguration > com.apple.AutoWake.plist & com.apple.PowerManagement.plist
    2) Do an Open Firmware reset: Hold the CommandOption+OF keys during startup. At the '>' prompt type:
     >reset-nvram
     Return
      >set-defaults
     Return
      >reset-all
     Return
    Reset PRAM:
    1. Shut down the computer.
    2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    3. Turn on the computer.
    4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    5. Hold the keys down until the computer restarts and you hear the startup sound (bong) for the second time.
    6. Release the keys.
    3) Reset your PMU.

  • Help with randomly sleeping PowerBook

    I have a 15" 1.5 Ghz powerbook that started going to deep sleep at the drop of a dime last week. I've eliminated any software issues (complete re-install of the system) but it still persists. It happens no matter what I'm doing, on or off a network, running multiple applications or no applications... The only thing I can find in the logs is this line "localhost mDNSResponder: Repeated transitions for interface en1 (my IP address); delaying packets by 5 seconds". en1 appears to be Airport.
    This happens every time before the system sleeps! Has anyone else come across this and if so have you found a solution.
    My machine is now out of warranty but it's not that old (just over 2 yrs).

  • PowerBook randomly shut off, no longer boots - URGENT

    I have a PowerBook G4 15" 1.33GHz that up until now ran flawlessly. Today I was watching a movie on it with some friends when it randomly shutdown. Since then, it no longer turns on. The battery is fully charged and there is no problem with my AC adapter. With just the battery, nothing happens when I press the power button. When the AC adapter is plugged in and I press the power button, the optical drive spins at full speed for a few minutes and then the PowerBook shuts itself down again. I have attempted reseting pram and pmu with no success. Any suggestions?

    Hi,
    I have similar problems with my PB which I got it used from a friend of mine about 3 years ago and ran flawlessly until last week. Everything worked until one day i came back home and tried to wake the computer from the screen saver and there was no response even after having pressed every single key and key combination possible. I have done a bit of research and people had similar problems. I then booted it up with the recovery disk and it says that the SMART status failed from the disk utility. I went down to purchase an HD and I've installed it. Perfect, everything was running.... after having tried booting it 50 times with PMU and PRAM methods. I've installed Leopard soon after, even updated to 10.5.1 and when i put it to sleep, it won't wake up properly after i wake it up. However, I can hear the fan, but not the HD nor the optical drive.
    So anyone has the same problem? My PB will only start up 10% of the time only from being completely off. It also won't wake up from sleep properly, it turns on, but the screen is black and HD won't turn, same with the optical drive.
    I'm sorry that this is a long message, but this is my workhorse and I just lost all of my school work and I'm freaking out. A little help, please?
