Macbook Pro will not rewake from sleep, but is running?

My Macbook pro with OSX Lion and Core 2 Duo will not wake from sleep. The screen stays black (as if it were off) but I can hear the fans running and the light
on the front stays on steady.      I have tried to hold down the power button to shut it off- Didn't Work         I have drained the battery and restart- Didn't work

  • Macbook pro will not wake from sleep without shut down?

    My macbook pro 2007 will not wake from sleep without holding down start button and then restarting? Is this a serious problem?

    You can Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
    You can run the Disk Utility> Repair Disk from Recovery ( command R on start)
    if that does not sort it I would reinstall OS X

  • MacBook Pro will not wake from sleep

    My new 13" MacBook Pro will occasionally refuse to wake from sleep. Touching the keyboard or moving the mouse will turn on the keyboard background lights but the computer will not wake. This occurs without any peripherals attached.  I have reset the PRAM and the SMC ... no help.
    The only option for recovery is the hard power down with the power button and restart. Anyone else seeing this?

    Yes and I hate it. I am having pretty much the same problem, and have tried the same solutions, also Iupgraded to Lion and there still has been no relief. My computer just runs slower.

    ps my macbook air has never been rebooted and i've had it a year! it loves sleep...

    I have a similar issue with my MBP, it's been on-going for a while but I just never had time to stop and deal with it.
    This week I had a new logic board put in, low and behold it's still doing it (I get a kernel panic after resume).
    Trying to track it down myself now. AHT and everything says the hardware is fine, fresh install (erase with 0 on disk) and all updates, no 3rd party software.

  • My macbook pro will not go to sleep

    Macbook pro will not sleep by any means except when it is on battery and if I plug the power back in it will stay sleep for a while and wake up on its own. I have spoken with express lane and verified the HD and the premissions, etc. and it worked for a when and the problem returned.

    My MBP does this on occasion as well.
    It also used to make a terrible processor noise, but I just got the logic board replaced through apple care. So far it has not had the sleep problems since i got it back, but it has only been a week, so who knows.
    also make sure you have updated the firmware, if you have one of the early models it may be outdated (like mine).
    I never did figure out a permanent solution, but it seems like it happened a lot less after the firmware update.
    Good luck, I'll let you know if mine is in the clear with the new logic board

  • 2012 MacBook pro will not power up sleep light on then off

    Please help my mid 2012 MacBook pro will not turn on. When I press the power button the light on front comes on and the cd rom drive attempts to start then it shuts back off. I have tried holding down the power button and pressing the button combo to reset the controller.  Thanks for any help.

    You may have to take the MBP to the Apple store as soon as possible.
    Best.

  • Wiped macbook pro will not boot from install DVD

    I recently purchased an older MacBook Pro that came with the OS system wiped but it did have the original Install DVDs.  The computer will not boot from the DVD.  I have booted holding down the C key and nothing happens.  I have booted holding down the Option key and it shows the Install DVD and I select this and nothing happens.
    How do I get it to open up the Utilities from the DVD to install the operating system?

    It could be a problem with the optical drive, but also may be due to the DVD's being for a different model.
    Exactly which MBP do you have, and what serial numbers are on the discs ?.

  • 2007 macbook pro will not go to sleep...

    Whether i close the lid or use the command it will not go to sleep. If i close the lid the little white light in front goes on bright and stays. If i use the command the white light goes on dim & stays that way. I've tried resetting the SMU (?) by removing the battery and holding the power button down for 5 sec, but no luck.
    Anyone have any other suggestions?

    OK.

  • Macbook Pro will not boot from any source after upgrade

    Hi,
    I have a late 2011 Macbook Pro - standard issue other than more memory as I recall. It has a 750MB hard drive with more than half still free. All the checks given below are done with the computer stand-alone with no hardware attached - other than the power cord and of course WiFi.
    2 weeks ago I upgraded to Yosemite having taken all the right precautions before upgrade - thanks to Take Control. It worked fine and I was getting a good experience until last Wednesday when I put it to sleep by closing the lid. Later in the day I opened it up again but only got a grey screen. After leaving it several minutes to see if it cleared I shut down by holding the on button for several seconds then tried to re-boot. The computer starts and gets as far as the grey screen then shuts down again after several minutes. Sometimes it will continue to restart after shut down and keeps doing this until I again hold the on  button in until it finally shuts down for good.
    I have two bootable drives - one is a cloned backup of the previous version and all the data, the other is an 8GB thumb drive with a bootable version of the Yosemite installer. For the record I also have a Time Machine backup and a second full clone backup and recovery drive on a Synology NAS device -  I just haven't figured out how to boot from this device as yet.
    I can get to the boot up selection screen (hold option key) and select an external drive to boot from but it makes no difference - I still get the same grey screen. Same thing if I use Command +R to boot from the Mac HD recovery partition.
    I have also tried to boot into safe boot mode (hold the shift key down). This seems to slow everything down but ultimately has the same result - a grey screen.The only difference I can see is that this grey screen does not shut down after a time. Seems to just continue until I shut it down manually.
    I can hold Command +V to remove the grey screen and see the action being written to the screen while logging on (white text on a blue screen) - up to a point.  After some time I just get the same grey screen and it shuts down after more time. I can also use Option +D (I'm told it should be just hold the 'D' key to do this but that has never worked for me and Option +D does) to get to the hardware check and I have run this both before upgrading and after having the problem. Before upgrading I got one error - 4ETC/1/40000002. I looked this up on the Internet and could find nothing specific to identify the problem and the general consensus seemed to be it was nothing major. After upgrading and running the hardware check again (after this problem occurred) it returned no errors.
    I have reset the PRAM with the same result as before - all I get is the is the Apple logo and a progress bar that increases to around 50%, then both disappear and I get just a grey screen. After a time the computer shuts down and then restarts again and goes through the same process.
    I've done pretty much everything I can think of and find in books and on the Internet. Hoping that someone out there will find this problem interesting and help me to resolve it.
    Tony

    Problem resolved. I took the machine into an authorized repair facility where, for around $30, I had it checked and the logic board replaced. Picked it up yesterday and seems to be working OK. No cost to replace the logic board even though the machine is over 3 years old. There seems  to be some sort of dispute with Apple over a class action that has worked in my favour. Great. I'm happy.

  • Macbook Pro will not boot from USB drive or Macintosh HD

    The Mac in question:
    Macbook Pro mid-2009
    2.4GHz Core 2 Duo
    4GBs RAM
    OSX 10.8.4
    Basically I did a fresh install of OSX 10.8.4 and Installed Windows 7 Home Premium 64bit via Bootcamp.
    All software was up to date, I had the newest version of bootcamp for windows software, and everything was working fine.
    I lent the computer to my dad
    fast forward 3 months.
    Windows boots fine and works for about 15 minutes then Blue Screens and restarts. Endless loop.
    I did everything conveiveably possible for the Windows side before deciding to work on the Apple side.
    Come to find out, my dad had not booted into the Apple side for almost 3 months. So on holding option and selecting the Macintosh HD icon, I got the apple logo with a spinning wheel under it. The wheel spun for about a minute then stuck. No response, so I held the power button down and restarted.
    held option, and selected "Recovery 10.8.4" same deal minus the spinning wheel. stuck on the apple logo.
    so i plugged in my bootable mountain lion usb (has been used countless times and works, its not the usb) and selected the usb. Same stuck apple logo.
    I am at a loss as to what to do now. I dont care about any information on the drive, so i dont mind formatting and such.
    But i am at a loss as to how to repair it if i cant access and bootables to do a disk repair or a clean install
    Any suggestions would be helpful, thanks.
    (btw, ive reset SMC and PRAM and all the usuals and ive internet searched out the whazoo, so yall are my last resort *grin*)
    -Dusty

    New info:
    Selected Recovery disk in boot options menu and it loaded.
    Disk recovery disk verification says there are errors with Macintosh HD but it cannot repair them.
    Tried Reinstalling mountain lion from the Recovery screen and followed the instructions, signed into my Apple ID and it started installing mountain lion on Macintosh HD.
    It immediately said 4 hours to complete and the blue progress bar started moving slowly.
    it says it is "Downloading additional components, your computer will restart automatically"
    about an hour later i checked it and the bar was full, but the estimated time was 1 hour 59 minutes and it has been almost 12 hours now.
    Just trying to give a play by play so yall have something to work with.
    making a Mountain Lion bootable USB as i type, will try that as soon as its done.

  • MacBook Pro will not boot from Apple Logo Screen - No HD recognised

    Hi all,
    I encountered a problem booting my mid 2010 MacBook Pro yesterday. I currently run OSX Mavericks.
    The computer has been great for the last 4 years and has never encountered any major issues. Yesterday I dropped it on carpet while sitting on the couch (it was a VERY small impact) and I continued to use it for a few hours. I did a safari update that night also. I then closed the lid which would have put it to sleep. My flatmate asked for a file later that night, I took his USB and stuck it in my computer, THEN opened the lid. The computer never booted up (It was stuck on the apple logo with the spinning thing underneath it). After doing this for a minute or so the computer would turn off. After multiple attempts the same thing happened.
    I read many posts on this - I am assuming that the problem occured because I brought it out from sleep with a USB in the side. I have taken the following steps to attempt fixing the problem -
    *safe boot - no luck
    *reset PRAM - no luck
    *recovery mode boot - getting disk errors.
    In recovery mode boot I cannot reinstall a new OSX version because there is no internal HD disk mounted. It only gives me the option to install OSX to the Recovery HD, which is locked.
    Using Time Machine backup wont work as there is also no Internal HD detected to load to.
    In Disk Utility it no longer has 'Macintosh HD' - It is further labelled 'disk0s2'. I cannot verify, repair OR erase this disk.
    Can someone PLEASE assist with what I might be able to do. I need to somehow mount/unmount/detect my internal HD. I am happy to detect it and format it as I have Time Machine backups on an external HD.
    I am no mac genius although I do learn quickly. If I can get assistance It would be very appreciated. I have a feeling I can sort some issues out using Terminal although I need command assitance?!?
    Apologies for the long post although I want to outline everything I have done to attempt to isolate the problem.
    Thank you all in advance.

    Does your flatmate have a Mac as well?
    If so, you could always get a 8GB+ USB stick, download Mavericks using your Apple ID and use DiskMaker X to create a bootable installation disk on the USB stick. Then boot using the USB stick (hold down the option ey whilst booting to select it) and try to reformat your drive using Disk Utility and, if you're able, reinstall OS X on your machine and then restore from backup.
    The only hitch may be that your hard drive is dead and that you need to install a new drive. You'll know once you boot from the USB stick, though, if you can format the drive or not.
    Good luck,
    Clinton

  • Macbook Pro will not boot from internal drive

    I have a macbook pro model indentifier: macbookpro 7,1. The system would not boot what I have tried is first running apple diagnostics and all test fine, I tried booting from a snow leopard cd to re-install and it would not boot from the cd, however it does boot from the techtool pro 6 cd. I did run the test in techtool pro and all check out ok.
    I removed the drive from the system and connected via usb to test and it boots fine from usb, put back internal and same result no boot. I did some research and I see that someone had a similar problem and it was the sata cable, but since the diagnostics test ok I am not sure that would be the problem.
    Any Suggetions, this is driving me crazy
    Thanks in advance

    coffee would not HAVE to do anything except mechanically. It would not have any effect now since it has dried out, well short of corroding some components.
    Check the points where the HDD casing "meets" the Macbook casing. How much pressure is there?
    What about the pressure pins "pogo pins" are they all functioning?
    What about pressure on the cables?
    Please describe how it wont boot? What exactly does it do / happens

  • MacBook Pro does not wake from sleep in Lion

    A lot of people are reporting that their MBP freezes (which happens to me, too) but this concerns a totally different issue.
    About 5-10% of the time, when I return to my MBP after it has initiated sleep, I cannot get the system to respond.
    Keyboard should wake the MBP. Power button should wake. Opening the lid should wake. None do.
    The system is cold. No fans, to backlight, to nuttin'. All that works is the sleep indicator, which turns on and off when I open and close the lid.
    The only way to use the system is to force restart (hold down power, reboot) at which time the system does its 'resume'-thing... as if it ran out of juice and went into hibernate.
    How do we fix this? I'm running a clean install of Lion (10.7.1) (same issue with 10.7.0) - installed it fresh after formatting the HDD - so Snow Leopard remnants from upgrades cannot be a problem here.

    I began having issues whereby my Macbook Pro would freeze after waking from sleep...whether automatic sleep mode or manually-induced.  Got worse by the day, so I looked in this Forum and found that the problem was widespread..
    My issue came when I tried to open MS Office Mac (Outlook) or open Firefox.  In nearly every instance, the computer (and sometimes the screen) would freeze, sometimes with the little whirling ball remaining on forever.  All these forced me to power down with the on-off button, which was distasteful.
    After reading all the posts in the Mac forums regarding this issue, I determined that the issue most likely to have caused my problem was Microsoft Silverlight.  I recalled that I had recently allowed an update.
    I went into every folder I could find, including those related to MS Office, and sent every incidence of Silverlight (including folders) to the trash.  Then I shut down and restarted the computer, and ran some tests by putting the unit to sleep and waking after a wait time.
    After several tests, I have determined that I am now back in good order, sans Silverlight.  I think Silverlight is off the radar for my future!

  • When i shut my display, my MacBook Pro will not go to sleep!!!!

    Hi everyone, i have been having a problem recently with my MacBook Pro, and as the title suggests i am having a problem with putting my computer to sleep. For some reason when i shut the display to put the computer to sleep, the computer never actually goes to sleep. The light on the open button turns on but it doesn't turn to the normal gradual pulse. The screen actually turns off but the hard drive never stops running. Many times i don't realize this has happened until hours later when i actually come back to my computer and it is just in that same state. When i come back to the computer it is also very hot. When i try and open the display to get back on my computer, however, nothing happens at all. its almost like it just freezes while trying to sleep. The only thing i can do at this point to get it out of this state is to hold the the power button in and restart the computer. I should note that this problem occurs probably every 1:15 times i put my computer to sleep. Any help concerning this problem would be most appreciated. Thanks again!!!

    My MBP does this on occasion as well.
    It also used to make a terrible processor noise, but I just got the logic board replaced through apple care. So far it has not had the sleep problems since i got it back, but it has only been a week, so who knows.

    Good luck, I'll let you know if mine is in the clear with the new logic board
