Powerbook won't wake from sleep when unplugged from power

hi everyone,
i have a 15" 1ghz titanium powerbook, running 10.4.6.
recently (maybe since 10.4.6?) i haven't been able to wake the machine from sleep when i unplug it from powering up in sleep mode, to open it up someplace else to run it on batteries for a little while. i always have to do a hard-reboot (holding down the startup button for several seconds). this usually destroys my dock and other preferences when i'm "back in".
does anyone know what might be causing this? it seems to be a recent development. it's unpleasant, because i frequently have the powerbook charge itself while asleep, and then i want to unplug it and quickly do something in another room running it on batteries. afaik sleeping and awakening works fine as long as i don't plug/unplug the power cable before waking it up.
any hints would be greatly appreciated...thank you!

Hi A.L.,
I have a Cinema Display which I often use on the back of my Ti. I know the laptop will not wake if there is no power and it has an external DVI display attached.
Perhaps your computer thinks it has some monitor attached - perhaps checking the DVI port for damage would be worth it?

  • PowerBook won't wake from sleep mode

    My PowerBook G4 won't wake from sleep mode. I open the lid and nothing happens. I hold down the power button and nothing happens. I resetted the PMU and it will wake up and I am able to login and then it goes back to sleep mode. What should I do please help? And if my computer is dead, is there any way to retrieve my information saved on the hard drive?

    this would happen to me when my battery was dead. you test the battery life? (little button on bottom near battery)
    I'd make sure it was plugged in and let it charge for 10 minutes or so. then try restarting it if it doesnt wake up by itself.

  • Powerbook won't wake from sleep

    My G4 1 ghz. 512 MB SDRAM 10.4.7 powerbook has started not waking up from sleep recently When I open the lid it won't wake up and the lighted power cord plug turns amber instead of green. Resetting the PMU botton doesn't do much. It sounds like the drive is running inside. Lately I have been removing the battery and pressing the start button. Then when I replace the battery It will then restart OK and I run Disk Utility to repair permissions.
    It will work for a few days or a week or so then it does it again. Any advice?

    If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
    Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
    Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following line:
    reset-nvram
    press the return key on your keyboard
    set-defaults
    press return
    reset-all
    press return
    Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
    Still did'nt work? Might be time to call AppleCare or see an Apple Genius or a technician.
    Also try posting this in the proper Powerbook forum, if the above doesn't work, in case it's a Powerbook issue.

  • Lid won't latch - powerbook won't wake from sleep, must power off and on -

    the catch on the lid of this 12" Powerbook G4 does not come out when the lid is closed; it can be brought out with a small tool. what is going on? the computer does not wake from sleep eitherl, must be turned off with power button and then turned on. If only the display is set to sleep, then it wakes up as expected. Are the two related? Is this a case for resetting the Power Management Unit, I could not be sure from the Apple article.

    Bob:
    Try starting up in Safe Mode, logging into your account, emptying Trash, then rebooting normally. I have found this helpful when I have had sleep problems with my Pismo.
    Is this a case for resetting the Power Management Unit,
    Wouldn't hurt to try.
    In terms of your latch, it is likely a mechanical problem. When the tongue is pulled out try putting a very small amount of lubricant on the tongue and working it back and forth.
    Good luck.

  • Compter won't wake from sleep mode

    My Pavilion 17 notebook computer, purchased in Oct. '13, won't wake from sleep mode; I must shut down and reboot each time.  I know this is not due to Windows 8, as I have another Win 8 computer that works normally.

    I've done some more experimentation and found a workaround. I had Sleep and the Screensaver both set to Never, and by activating the Screensaver the wake up issue has gone away. This doesn't change the fact that there is an issue with my ATV sleeping when it shouldn't and failing to wake up, but having the screensaver active stops it sleeping in the first place I guess.
    It's slightly annoying because I like to have music playing with the description and album art running, and this disappears when the screensaver comes on, but it is better than unplugging the thing every time I use it. Hopefully this will be fixed in the next update, because it only appeared in the last one.

  • 09 macbook pro, after 10.6.6 update won't wake from sleep without power

    Hey, weird thing going on here. After I updated to 10.6.6 on my '09 Macbook Pro it won't wake from having the lid closed unless the power is plugged in. I've tried closing the lid with the power still plugged in, and unplugging it before I close the lid. If I leave he power plugged in it works fine. If I unplug it after I've closed the lid, or even BEFORE I close the lid (and give it time to calculate battery life and everything) it turns off like it was a out of battery and I have to hold the power button down to make it wake, then it does the blurred out screen with the progress bar at the bottom (like recovering from low battery), but eventually comes back. The battery indicator on the bottom shows it has a nearly full battery when this is happening. I've tried adjusting sleep and power/energy saving settings but nothing has fixed it.... anyone got some ideas? It never did this before the 10.6.6 update
    Thanks!

    Im having the same issue.
    Seems to have happened just after 10.6.6 upgrade
    Battery only has 80 cycles on it and shows full charge
    i dont get the hybernate wakeup screen, but shuts down promptly after unplugged, and wont startup without power.
    Tried:
    *SMC RESET-holding power without battery in for over 5 seconds...no change
    *P RAM RESET-holding commandoption+pr during startup... no change
    *Installed applejack and ran all options... worked... for about 20 minutes then shutdown
    *Changed sleep settings...battery settings...hibernating settings...
    im outta ideas....

  • Since upgrading to version 10.8.2 my MacBook Pro won't wake from sleep is her anyway I can fix this?

    Since upgrading to version 10.8.2 my MacBook Pro (late 2009) won't wake from sleep is her anyway I can fix this?

    > during the entirety of this process the cursor was a "busy" pinwheel/beach ball/whathaveyou for a solid 30 minutes before I turned the computer off with the power button.
    All that cursor means is that it is busy trying to do something.  You can see if force quitting solves the problem with a simple force quit using command-option-escape.  If you are having issues with iCal quitting, sometimes it doesn't always know whether or not it is properly communicating with a particular calendar.  This can be a Mobileme issue, or even a phone synchronization issue, or a network issue reaching a shared calendar.  Shutting down a machine directly from a cursor is the last step one should try, only after all others have failed.  If you have done this in the past, lurking corruption can get worse each time with the directory, and upgrading the system will only enhance any corruption already present.  When you restart your Mac, does everything appear to be normal?

  • Macbook won't wake from sleep

    My macbook won't wake from sleep.  I have to power down and restart.  I have also noticed that when it is asleep, the sleep indicator light doesn't pulse, it just stays on steady.  Could this be a bug in mavericks?  I have a Seagate external hard drive that I use for my Time Machine backups that it always connected.  But ejecting it before the macbook goes to sleep doesn't seem to solve the problem.
    Any advice would be appreciated.

    You can access System Logs and other information on the computer's status in Console utility; where there are endless lists of all the processes ongoing in the Mac OS X. There are specific log-out and other automatic items the system will post to such logs.
    •OS X:  When your Mac doesn't sleep or wake
    http://support.apple.com/kb/TS5357
    Such articles are helpful in so much as they also have additional links.
    Perhaps the computer is not going to sleep. The system logs can tell this.
    Regarding power management, sleep, and other activities, have you read through the article about the System Management Controller to see if any of the items listed there can help? They'd take time to go through the list. And the end item is a reset of the SMC, after reading through and troubleshooting from the list.
    •Intel-based Macs: Resetting the System Management Controller (SMC)
    http://support.apple.com/kb/HT3964
    A good idea is to make a backup of your content in the computer, to an external hard disk drive, so when or if you end up totally erasing the hard disk drive (to include secure erase one-pass overwrite) and reformat GUID, that an all new system could be installed on there, in part of a larger troubleshooting effort.
    Actually, if you have an externally enclosed hard disk drive with its own power supply, (not port power) and then use Carbon Copy Cloner (see Bombich software) to make a bootable clone of your entire system to a large enough external drive capable of booting in OS X, then you could get to the bottom of this issue. While keeping a boot copy of what you already have, because you can run the computer from an external clone.
    •Mac Backup - Carbon Copy Cloner:
    http://bombich.com/
    A good source for external drives that can handle clones
    is macsales; or a place to look to compare real details.
    The problem could be based in software, or in hardware. Troubleshooting against either possibility is how to resolve this problem. Some models of earlier MacBook & other intel-based Macs do not really like Mavericks; or perhaps like it less than an earlier system it may have shipped with. The earliest like Snow Leopard best.
    Anyway, there is a solution but it won't be a one-liner.
    I've done some 40 hour days, troubleshooting issues.
    Worst problem for me was buying one w/Applecare.
    Good luck & happy computing!

  • MBA won't wake from sleep while connected to VGA Display

    Since a few days I'm using a VGA Display connected through the official Apple Mini Displayport - VGA Adapter. However, when I put my MacBook Air to sleep and then close the lid (otherwise closing the lid will just continue on the display). Keeping the monitor attached, it won't wake from sleep anymore. Disconnecting the adapter at that moment won't make any difference. What troubleshooting steps can I make?

    I usually...
    Take out the charger
    take out the battery pack
    reinsert the battery pack
    Then click the power switch
    (if you have low battery I'm sure it would be a good idea to plug in the adapter again

  • Macbook won't wake from sleep - replaced logic board and batteries already

    I have a 13" White Macbook on 10.5.5 that occasionally won't wake from sleep. This will happen with nothing plugged into the Macbook except for the AC adapter. I have done the firmware upgrade, reset the SMC, reinstalled Leopard from the DVDs twice, brought it into Genius and had the ram, sleep switch, and the logic board replaced. There are no bluetooth devices attached to the computer.
    I've searched the forums but haven't found a definitive answer yet.

    I've experienced the problem as well. I have the new aluminum macbook with all factory specs and no mods, except that I changed it from smart sleep to the original old mac behavior of instant sleep. It is intermittant and with mine, I've noticed that when the screen is open, the computer appears to be completely off, but when I close the computer the light on the front of the computer comes on. The only resolution I've found so far is to hold the power button for 5 seconds for a hard power down and then push it again--everything works fine.
    There is indeed a sudden drop sensor, and in fact, it did happen after I accidentally hit the corner of my mac once on a tv while trying to set it down. That could be the answer...we might have to try disabling that because quite honestly, if I drop my mac while its on, I'm going to be more worried about the screen, the case, even the cute little plastic apple than the hard drive (I have backups galore).

  • Suddenly won't wake from sleep.

    All was well but suddenly the Powermac G4 (gigabit ethernet) won't wake from sleep. Tried resetting the PMU (battery out and button pushed). Tried resetting the PRAM. Tried deleting the energy preference file. Even tried installing 10.5 on this old baby (runs just a slowly as ever, but startup takes an age). Can't run hardware testing because there's a bad firewire on the motherboard and it just stops there. Don't know what else to do. Why? this is my music server and it uses just as much power as my refrigerator if left running all the time but only needs to run when playing music.

    If the SMC reset doesn't work try this.....
    If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
    Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
    Try resetting the PRAM. This should reset the NVRAM on most machines, which is the suggested fix.
    Then put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.

  • Macbook Pro 13" won't wake from sleep

    Have mid 2009 Macbook Pro 13" that repeatedly won't wake from sleep.  Either putting to sleep via lid closure or sleep command, seems to enter sleep OK.  Sleep light slowly flashes indicating sleep.  When I open lid, light goes out but screen doesn't come on.  I have hold power button down to force it off and reboot.  Very annoying.  Occasionally, the laptop is warm and you can hear the fan running.
    I have taken to Genius Bar twice to no avail.  They could duplicate the problem the first time I had it in and ran some type of software repair.  Didn't permanently fix issue.  Second trip they tech thought it might be one of the two internal sleep switches.  She ordered them but when they ran diagonsics on those switches, the said they were good and didn't replace or repair anything.
    I have replaced both HDD and RAM and reinstalled 10.8 but problem continues.  Any suggestions?

    Not sure if this will help--but my MacBook was having similar problems. It would fall asleep and then when I would try to wake the computer, the screen would stay black but the computer was running.
    Here is what I tried:
    Turn of your mac
    Press the power on button
    Immediately after you press the power on button: hold down the following 4 keys:
    Command + Option + P + R. Continue to hold them down until you hear your mac make the power on sound twice. Once you hear it twice, let go of all keys.
    This should re-set the sleep settings. Worked for my computer, I hope it works for you if you haven't already tried it.

  • IMac G3 won't wake from sleep?

    I have a iMac G3 500Mhz computer with 128Mb of ram and just recently added another 512Mb chip. My question is that my mac won't wake from a sleep, and when it is restarted it always goes to the disk aid whether the computer was shut down properly or not and that takes for ever. It never use to take so long. I also noticed that in some website, yahoo for instence it hangs while I try to receive my email. I have tryed to zap the pram I reconfigured my desktop I've fist aided it and it say's everythings fine. What could my problem be? I live in newfoundland and no one here know anything about macs. I had a guy over to try to fix an earlier problem but I think he made it worse. He uploaded a version of osx and I had os 9.1 but I couldn't retrieve any of my old files because it wouldn't classic share so I had to redo os 9.1 over everything. Could I have messed something up in the process to make my computer do all these funny things?

    You should be able to get it from electronics stores (and probably from mega-computer stores) or from Radio Shack type stores. If they are charging more than $10, an online order may be cheaper even if there is a shipping charge. I have bought these batteries here with good results.
    http://eshop.macsales.com/Item_Specials.cfm?ID=2524&Item=NWTBAA36VPRAM
    I don't have your type of iMac CRT, but it should be an easy replacement. You can find instructions online, or just ask here...
    This article below lists things that are stored in PRAM, but people here have describe many different issues that where related to a weak or dead PRAM battery. Many had to do with startup issues.

  • Won't Wake From Sleep

    I held off from posting this until I'd scoured the boards looking for ideas, but I'm totally out.
    Every since I updated to 10.4.8, my MacBook Pro won't wake from sleep. I've tried resetting the SMU and PRAM, enabled and disabled bluetooth device wake from sleep, and installed the latest EFI Firmware update that was just released. I've now narrowed it down to the 10.4.8 and a change in how it handles Expresscards. If I have my NitroAV FW 800 card plugged in during a session, it seems to prevent the MacBook from going to sleep properly. According to various Console messages, the PCI device prevents the computer from going to sleep, and /or places the computer into System Doze instead, from which it won't wake. The sleep light stays fixed and steady, only disappearing if I press the power button (it only reacts to the power button). From there the screen remains dark and all plugged in device fail to respond. I can hear the drive spin back up.
    It reacts the same whether or not I eject the card before putting the computer to sleep. This behavior was not present before installing 10.4.8 and having fallen back on a back up of my 10.4.7 install, can say it's not present in the older OS version. I was hoping last night's EFI firmware update would deal with this, but after having installed it and 10.4.8 anew, I'm having the same old results.
    If anyone has any new ideas or can direct me toward how I can make sure the folks at Apple see this, I'd greatly appreciate it.
