My computer sleeps and doesn't wake up

Battery might have run down, but even when plugged into AC, computer won't start up. It appears to be sleeping, but won't wake up even though I'm giving it juice.

I have the same computer, and probably the same problem. I never had any problem with sleeping and waking until one day when I closed and then opened and then closed the computer lid all in about a second. From then on, if I ever did a sleep by either closing the lid or selecting "sleep" from the Apple pull-down menu, the chance that it would wake up was about 1 in 10. The rest of the time, the disk would spin up but the screen was dark. There was nothing I could do except hold down the power button for 5 seconds and then restart. This was exceedingly annoying, as quickly sleeping the computer with all of my applications up is one of the best things about the laptop.
I got on the Apple phone support line and they told me to do an "archive and install" with my original disks, but it didn't help, so the expert I finally got on the line said that it was probably a bad switch in my lid and to take it into my nearest Apple service centre. This I was loathe to do, because the most convenient one is run by the biggest bunch of jerks, so I put up with having to "Shut Down..." from the Apple menu and then restarting for a few months until I had time to take it to another place which is less convenient.
However, recently I bought Leopard and did an install. Presto, my problem disappeared! It looked like a file was corrupted and was not fixed with "archive and install", but was with a new OS. I wish I knew what file that was.
I should say that I also disabled the "safe sleep" option, which was mentioned as a potential problem when I was researching earlier. I greatly prefer having no safe sleep, because sleep now takes 2 seconds instead of almost a minute.

  • Since I upgraded to Maverick when computer sleeps it will not wake up but must be restarted?  Also password to icloud is never saved?

    Since I upgraded to Maverick when computer sleeps it will not wake up but must be restarted?  Also password to icloud is never saved?

    I read someone said you can tap on "other" when selecting which wifi you connect to and then entering the exact wifi name of the network you wish to join and the password and then joining that network allowed the password to be saved.  Also with iOS 6 the minimum length of the password needs to be 8 characters.  Maybe you password on your router is less than 8 characters long

    Ops I replied to myself in error.....
    Tom:
    I performed the steps indicated but this morning when I clicked the mouse and hit the space key and clicked the track pad again as before nothing happens.
    I hold the power button for a few seconds and the screen fills as if the computer was normally awakened but it is locked up.
    Then I have to shut it down with the power button  and then power it up as a reboot.
    Not good...SMC reset didn't work....Throughout the day yesterday I put the computer to sleep and woke it up normally.  It seems to be a overnight problem.
    Am I going to have to shut it down everynight?

    My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem

    Hi I've been following this thread (along with a different one on the same topic). I've been having the same problem with my ibook. I can add that I have no problem with startup. It's just that the screen "goes to sleep" unexpectedly and may operate normally for a few minutes or a few hours at most. Opening and closing the lid or restarting seems to cause it to awaken but then usually for just a few seconds or minutes. If it is connected to another video display that display continues functioning fine even though the computer screen is blank. In addition the desktop is there and visible faintly or if totally blank can be backlit through the apple logo and can be read. I've had my logic board replaced twice under the extended warranty and assumed it was that but now I'm thinking of the reed switch. Apple refuses to consider any further work under warranty as the last repair was in Jan, 06 and they claim only a 90 parts warranty and the machine is from 03. Any thoughts before I cut the wires? I have reset the pmu, run cocktail and disk utility. Other than the sleep issue the machine works fine. thanks Ronda or anyone else who has any ideas... Dave

  • Why does updating virus definitions on microsoft security essentials make my macbook go to sleep and hard to wake it up from its sleep state?

    Why does updating virus definitions on microsoft security essentials make my macbook go to sleep and hard to wake it up from its sleep state? does this happen to anyone else? its really bugging me.

    Just  you probably, having used it for years since its beta days.
    don't run more than one malware suite/programs. it is possible to use some as long as they aren't running.
    I'd look elsewhere for why.

  • NEW iBook and doesn´t wake up after sleep mode!

    Hi,
    I´ve just started to use my new iBook G4 3 days ago, added my user information, and for a little while the wireless internet connection. Then, I closed the display to put it on sleep mode.....and.............it DOESN´T WAKE UP!!!
    The hard disk seems to start up correctly (the fan is on and the disk noise is ok), the Caps Lock on the keyboard is on too, but as soon as I reboot the computer, a strange beep (like a phone tone!) starts up, then the sleep light signal flashes but the screen stays black.
    I think that by now I´ve tried the most solutions (as far as I can having the black screen) I´ve read on the troubleshooting page and the recommendations posted in this Discussion chat... The iBook remains partially dead.
    Help!!!

    ummm, even when its not plugged in to the power adapter? i find that when my ibook annoyingly doesnt wake from sleep, its usually because i connected/disconnected something while it was sleeping. even plugging in the power adapter seems to affect it. the way i fix it is to put it to sleep again, and then open the lid. its worked every time so far.
    oh, and apprantly 'manually' putting the ibook to sleep does the trick (ie from the apple menu)

  • Display sleeps but doesn't wake on click or tab

    Hi,
    I have a Mac Mini(mid 2011) with came with Lion. I just upgraded to 10.7.2 and since then there is an issue with the sleep function.
    I have not put the mini to sleeep as i keep downloading large files or converting movies but the DISPLAY is set to sleep in 10 mins.
    IT was all fine but ever since the update, the display doesn't wake up once it goes to sleep. Even though i click the mouse or press keys on keyboard.
    A black screen prevails on the screen and the viable option left is to cut the power off and restart to access the screen. It is seriously hampering my ongoing tasks as they are closed abruptly.
    For the time being i have set the display to never sleep. But i am looking for a solution.  Has anyone else also faced the issue after an the update. Any suggesstions would be highly appreciated.

  • 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.

  • My iMac (10.6.8) goes to sleep and will not wake up without a hard reboot.

    My iMac (10.6.8) goes to sleep after 2 or 3 hours (even if im working at the time) and will not wake up without a hard reboot. 
    Any suggestions would be very much appreciated.

    What all USB or Firewire devices do you have connected?
    Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if sleep/wake works OK in Safe Mode.
    Reboot & test.
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.

  • My New iPad (16gb   4g) went to sleep,and won't wake up! What should I do?

    What should I do? Pls Help!

    Assuming that the battery isn't empty (and it can take up to 15 minutes of charging before it will respond), then have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • 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.

  • MacBook Pro mid 2010 putting itself to sleep and restarting on wake-up?

    My mid 2010 MacBook Pro has recently started having a lot of problems. It will put itself to sleep whilst I am working on it, and when I try tp wake it up it restarts showing a message saying 'Your computer restarted because of a problem. Press any key to continue..' however it doesn't tell me what the problem is. This can happen every 5 minutes or once an hour but it is becoming very irritating. I have previously done a PRAM and SMC restart, they made no difference. I can't think of any recent programmes I have installed to cause this problem, other than updating to mountain lion 10.8.5. Im not very computer savvy either, so understanding much of what is online is not easy.

    Thanks

    You have the MacBookPro6,2, the Edsel of Macs. It may be covered by this program:
    MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video
    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.
    Print the first page of the panic report, and the support page linked above, and bring them with you.
    Note that the replacement program only applies within three years of purchase. If you wait beyond that date, Apple may refuse the service. In that case, you'll be quoted a price of about $300 (in the U.S.) for a depot repair. The model was discontinued in February 2011, so the replacement program will be ending quite soon.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
    Sometimes the replacement part is also defective, so be prepared for that possibility.
    If it's too late for your unit to be repaired under the program, and you don't want to pay for a new logic board, you may be able to stop the panics by disabling automatic graphics switching.
    *An SSD doesn't need to be zeroed.

  • My computer sleeps, but doesn't

    When I close my laptop, the computer seems to go to sleep: the hard drive winds down and the light begins to pulse. But the console log suggests otherwise. Any thoughts? I have unchecked "wake for network access," have Bluetooth turned off, and nothing in the USB ports.

    I fixed the problem. When I was trying to clean the connector of the iPhone I must have bent some pins. I have straightened them to the best of my ability and now it syncs. If your iPhone charges, but doesn't sync, most likely you have a similar problem, because the iPhone doesn't need all of its pins to charge, but it does need all of them to sync.

Maybe you are looking for
