5 ways to fix MacBook /Pro/Air that won't wake up from sleep
Some MacBook, MacBook Pro or MacBook Air won't wake up from sleep. My MacBook Pro was one of them. I have been googling for two days, and I learnt different ways to fix the problem. Not all the MacBooks can be fixed by the same one solution. Here I collect five common ways to fix the waking up problem together (trying to save time for others). If your MacBook doesn't wake up from sleep, you may try and see which solution works for yours. If any solution works, you may leave a message including your MacBook model and the solution. It may help the others.
Solution 1.Select a Startup Disk in System Preferences
I learnt this solution from AJ's post. AJ said even in a single boot MacBook, a startup disk is rarely selected, and sometimes, this may stop MacBooks from waking up from sleep. Here is how to fix it:
Launch System Preferences from the Apple menu
Click on Startup Disk
Select the startup disk of the OS you are using (click the single disk if there is only one)
Solution 2.reset SMC
SMC stands for Mac's System Management Controller. Many strange behaviors are related to disorder SMC setting. By resetting SMC, you may fix sleep problem of your MacBook. Here is how to reset SMC of your MacBook.
Reset SMC of a MacBook, MacBook Air, MacBook Pro with an internal battery you should not remove on your own:
Shutdown your MacBook/Pro/Air
Connect the MagSafe power adapter
Press the (Left side)Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Press the power button to turn on the MacBook/Pro/Air.
Reset SMC of a MacBook, MacBook Air, MacBook Pro with an battery you can remove:
Shutdown your MacBook/Pro/Air
Disconnect the power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Install the battery back and connect the power adapter.
Press the power button to turn on the computer.
Solution 3.turn off Safe Sleep (hibernatemode)
Safe Sleep(or hibernatemode) was introduced in 2005. This Feature writes the content of MacBook's RAM onto the hard disk before you put the MacBook to sleep. Normally, when Macbook wake up, it does not need to read the hard disk for the RAM's content, because RAM is not turned off when Mac is sleeping. Safe Sleep is there just in case that the MacBook is short of power and turn itself off or you remove/change the battery. And that is why it is call SAFE sleep.
Sometimes, Safe sleep may cause MacBook can not wake up from sleep. You may try to turn it off, here is how:
Launch Terminal (/Applications/Utilities/Terminal.app)
run pmset -g | grep hibernatemode
If you see "hibernatemode     3", you may go on the process, or else you need to stop and try other solution
run sudo pmset hibernatemode 0
Enter your admin password
This very solution fix my MacBook Pro. If it doesn't fix your problem, you can restore the safe sleep feature with running following command line in Terminal:
sudo pmset hibernatemode 3
Solution 4.Switch system to another hard disk if you have two
If you have installed a second hard drive (or SSD) on your MacBook or MacBook Pro, and have waking up problem of the mac, you may try to install Mac OS X system on the other disk of the book.
I have removed my optical drive of my MacBook Pro, and installed a second hard drive. When I installed Lion on the second hard drive, my MacBook Pro could not wake up from sleep. Then I tried installing Lion on the original hard drive, the MacBook Pro did not have the problem.
Solution 5.Reinstall system
Backup all you data, and try re-install the Mac OS X system. It always will be a solution to Mac problem.
I hope some solution above will work for your MacBook. If not, maybe you just have a broken Mac, it is time call Apple.

  • Macbook to TV, Works fine until I put the Macbook to sleep then tv display

    Macbook to TV, Works fine until I put the Macbook to sleep,
    I wake the Macbook with external keyboard and the display shows up on TV just fine for a second or two then it looks like something changes and then it starts rolling.
    It does not do this when Macbook is awake it only does it after it's put to sleep.

    Probably the resolution is switching from a mirrored resolution to some other resolution that the TV can't work from. Try this; shut down the MacBook. Cable up the TV to the MB and also the external keyboard and mouse. Hold down the Shift key on the external keyboard, hit the start button on the MacBook and immediately close the lid on the MB after you've hit the start button. Continue holding the Shift key down on the external keyboard until you see the grey screen with the spinning gear at which time you can release the Shift key. The MB should now finish starting up in Safe mode with only the external screen being on. Hopefully the screen will not be rolling.
    Once the MB finishes booting, go into System Preferences/Displays and set the resolution to the optimal/desired resolution for your TV. Hopefully this choice will stick through subsequent restarts and also correct the issue of the rolling screen under the conditions in the scenario you described.

  • Putting Your Macbook to Sleep?

    What is the difference between closing your macbook & pressing apple-sleep? My friend aid that it is better to put your computer to sleep by pressing the apple then hitting sleep. I have been just closing it. Is there a difference? Is one sleep mode better than the other?

    I think years ago Macs did go into different depths of sleep depending whether you selected sleep or they dropped into sleep.
    However with the MacBook, well certainly with my MacBook, the sleep is the same whether I select sleep from the Apple Menu or I shut the lid. There is no difference, you hear the disk running for about 20 seconds whilst the hibernate image is saved, then the disk shuts down, and the fans stop if running, and the sleep light starts to pulse.

  • The new version of Itunes is NOT interfacing correctly with my Airport Express device and I get an error message when I put my macbook in sleep mode.  Anyone else dealing with this?

    When I put my mac in sleep mode I get an error message and I have to click on it and then select whethere to play on computer or airport express.  This was not true with the old Itunes but with this new version it is true.  Any help?

    well nobody bothered to give me a hint on what to do, maybe because the problems with the new version of iTunes are really a lot, there is an enormous amount of people out there that have all sort of different problems including mine  so I have decided to return to the previous version which works fine and wait untill the apple people come up with a decent product ....

  • Shall I Put My Macbook To Sleep Or Shut It Down?

    sorry for such a moronic question but I was wondering which would be better in the long run? I use my macbook for work from 8 to 2 in the morning and then shut it down. Then in the night around 9 Pm I sometimes use it again and leave it on for downloading stuff.
    However around 1 am I shut it down and then the whole process happens again.
    Being a windows user all my life, i have been in the habit o shutting down my PC, howver someone told me it affects performance in a Mac. Is that true?

    My experience is like Troy's - I don't shut down for any routine event. Heat is nil and it comes right back up on it's network (unlike the Windoze laptop I'm forced to use at work which wakes up quite grumpy...) Never seen a problem in 5 years from this on my 3 Mac laptops.
    Mine is set to automatically wake up on workdays when I do (System Controls energy conservation panel), then an iCal event downloads weather and traffic reports which are waiting for me when I sit down with my bowl of cheerios. As long as I was logged in when it went to sleep, that is, and it doesn't wait for a password. It's also set to Sleep after 3 hours of inactivity.
    Battery life is generally thought to be better if they're on a charger and 'floating' when not in use, so while the drain sould be very small overnight - maybe 10 minutes of run time?? - I would leave it plugged in, assuming you have the power adapter always with it, or a second at home.

  • Command-option-eject wont put my macbook to sleep!

    I dont know what the problem is here. Whenever i press command-option-eject, my display turns off and the sleep light turns on (non-pulsating), than about 10sec later i hear the cd-rom whir up as if it is coming out of sleep and the computer wakes up. Why isn't this working?

    Make sure you don't press and hold the eject key, just press it quickly and let go. If that doens't work, and you have anything plugged into the MacBook, try it with those things unplugged.

  • Cant put ipod touch to sleep or turn off

    My daughter has an older 8gb ipod touch, not sure which model.  For some reason it will not switch off or go to sleep.

    - First try a reset.. Nothing will be lost.
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears
    - Next connect to your cmputer and restore the iPod, let the battery fully drain. After charging fro an hur try the reset and restore.

  • Why did F4 beta uninstall itself after I put MacBook to sleep and had to be rebooted from the disc image?

    I put my MacBook to sleep with Firefox 4 beta open and when I went to use it again it had vanished. My spotlight search yielded v. 3.6 and the v.4 beta installation file (.dmg). I opened v. 3.6 and declined to transfer v4 Add-ons . All tabs that were opened on v.4 beta opened on v. 3.6. I closed 3.6 and reinstalled v.4 beta from the disc image. I was warned to replace previous version (3.6) - which I did. V4 beta installed intact (bookmarks, add-ons, history etc.) but I lost my open tabs. My only concern is that I was required to replace v. 3.6 and don't want to risk losing bookmarks and history if v. 4 proves unstable. I am otherwise pleased with the new look and performance.

    Yes, your iPhone has the classic signs of early onset Alzheimer's... 
    Assuming that nothing is pressing on the Home button when this occurs, try the basic steps as needed:
    1. Reset phone - press both home and sleep/wake buttons until the Apple logo appears.
    2. Restore phone in iTunes using a backup
    3. Restore in iTunes as new, without using a backup.
    If #3 doesn't help, there is a hardware problem such as a defective home button, and you should make an appt. with an Apple Store Genius bar.

  • Audio oddities on MacBook after sleep

    Here's the deal: I had 4 tracks of dialog I was working on for an animated movie. Each track had different fx settings. After doing some editing and such I saved the project, and put the MacBook to sleep to go on to something else. When I returned later to work on the project, all the waveform regions were present but 2 trx were not playing back any audio and one was only giving me 1 channel of reverb return but no dry signal, and one was normal.
    Weird.
    So I copied the project file onto a flash drive and opened it up on my iMac running 10.4, same exact situation. So I got crafty and moved the waveform regions to a new track and viola audio as if nothing had happened! Even applying the saved fx setups (Save Instrument...) from the old trx worked without a hitch.
    Maybe this is a gear specific problem, but anyone experience a similar situation?

    I just bought a Macbook and I am having the same problem. I am using a linkys wireless-G and I have it set to 64 bit encryption.
    Whenever I wake my computer from sleep mode the signal barely gets above one tic mark. I have to restart for a clean connection.
    Is this a hardware or software problem? Its very frustrating. I hope someone can explain why this happens.

  • How do I put my MacBook Pro to sleep?

    I just bought a new 13" MacBook Pro. I was going to refer back to the notes about putting it to sleep, but I misplaced the booklet that came with my computer.
    So what's the process for putting it to sleep? Can I simply close the computer, stuff it in my pack and carry it on a bus, or is there some sort of procedure I should follow?
    Also, is there an online version of the Getting Started booklet I can refer to?
    Thanks.

    Closing the lid will put the computer to sleep

    It may well be a driver issue but considering the loading: Xorg trying to load different drivers is somewhat normal. @cafe you can see that these are autoconfigured by X above the loading in the log:
    Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched intel as autoconfigured driver 0
    Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched intel as autoconfigured driver 1
    Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched modesetting as autoconfigured driver 2
    Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched fbdev as autoconfigured driver 3
    Jul 20 19:48:24 arch gdm-Xorg-:0[216]: (==) Matched vesa as autoconfigured driver 4
    As long as one of the drivers gets loaded, which it apparently does the failing of the others is fine.
    Was there an update maybe ?

  • HT6150 Single press of Power Button does not put my MacBook Pro to sleep after this update! Do I need to change anything in the settings? Any help please? Thank you!

    The title says it all! After installing the new Mavericks update, I cannot put my MacBook Pro to sleep after a single press of the Power Button like before. Does it have something to do with this update or my MacBook Pro? Or do I have to change something in Settings?
    Any help would be appreciated.
    Thanks!

    But remember that there are others.
    A moment is a medieval unit of time equal to 1.5 minutes or 1/40 of an hour. This reckoning is derived from the work of Bartholomeus Anglicus, writing in 1240 that each hour was divided into four points, each point into ten moments, each moment into twelve ounces, and each ounce into 47 atoms.
    In modern English it usually refers to "a short period of time",[2] the exact length remaining ambiguous.
