Macbook won't wake up from sleep.Must force shut down.

Here's the problem.When I leave it on (Macbook) overnight and I comeback in the morning the screen is black but the little white light is on(solid),but when I press the keys to turn the screen on I get no responce and I have to force shutdown it,it has happening frequently and I loosing to much information because of this, anybody out there with the same problem or similar?
Please help.

I don't have the SAME problem, but a similar one. I normally sleep my (Santa Rosa) MacBook when I'm not using it. Mostly it wakes up okay. Once in a while it doesn't, but docking or undocking my Palm (not doing a sync, JUST (un)docking it) causes it to wake up, probably other USB devices (disks, thumb drives, etc.) would do similarly. Once in a longer while, that doesn't work, but opening the closed case wakes it up, or hitting Shift after opening it does. Once in a GREAT while (two or three times so far) none of the above help, and I have to do a force quit. Since it was sleeping, as far as I know I'm not losing anything, but I hate to EVER have to force shutdown.

My early 2008 MacBook won't wake up from sleep

My early 2008 MacBook won't wake up from sleep periodically. I will have to hold the power button down and then restart when it acks up. It did this twice yesterday & once today.

Try resetting the PMU (power management unit).
Remove battery and power adapter.
Hold down power button for 10 seconds.
Reinstall battery and attach power adapter.
Hold down Command-Option-P-R, a total of four keys, and press power button. Don't release the keys.
Continue holding the four keys until you hear the startup sound twice, then release.

MacBook won't "wake" up from sleep, when being folded

When I "fold" computer it goes to sleep. But, when I flip up the screen again, my Mac won't "wake" up from sleep mode anymore.
Do anyone know how to fix this problem?

I have a MacBook 2.26 GHz Intel Core 2 duo, Snow Leopard 10.6.8.

I've solved my problem.
I have reset my MacBook's PRAM settings.
It's very easy: link: http://support.apple.com/kb/HT1379
Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.
Hope this helps
Best regards,
Christian

MacBook won't wake up from sleep / boot up.

My MacBook has trouble waking up from sleep, and sometimes booting up from a normal shutdown. When I open the clamshell after I put the computer to sleep, the indicator light doesn't blink, but is lit up, and the screen is completely blank. Pressed all keys, and still it won't wake up. I've had the same problem with booting up the computer from a normal shutdown as well. I've tried holding on to the power key and doing a hard reset, but nothing seems to work. However, I can't seem to pinpoint the cause of this problem, it seems to be completely arbitrary. Sometimes, it wakes without a problem, and sometimes it just stays in "zombie" mode for .. extended periods of time.
I've also resetted the PMU, and the NVRAM as well. I'm not sure how this could affect it, but a few days ago, my CD drive broke. When I tried to boot up, the CD drive seemed to be turning to find a CD, and couldn't boot up. So I took it to the Apple guy and got the CD drive removed completely. I took the MacBook back to him with this waking up problem, and he says it's fixed, but it really isn't.
Help! I can't

I can't boot up MacBook and I,m wondering if you tried SafeBoot. I went through the process, got the progress bar, then nothing. Just more blue screen and gear spinning.

Waking from sleep requires Forced Shut Down on two different g4 iBooks

Two different iBooks, a 12" 1.33 and a 14" 1.42 . Same behaviour on both iBooks.
Each is running 10.4.4, Each has 1g RAM. Neither have any unusual third party software or hacks. Both exhibited this behaviour prior to 10.4.4, and both had 10.4.2 as the original install, then 10.4.3.
Both go to sleep after three hours, display is set not to turn off before then. They will operate properly for days at a time, but approximately once or twice per week they will have gone to sleep normally, the white light blinking. I'll tap the keyboard to wake up, and the white light will stop blinking but nothing else happens. The cd drives don't make their usual start up racket, nor does the hard drive or fan spin up. Only doing a "Forced Shut Down" by holding down the power button and then restarting will bring either one of them back to life.
I have already Reset the PMU several times over the past 6 months with no change in behaviour. I have also reset the PRAM on both units sucesfully, however that also has not changed the behaviour.
Were this happening on only one iBook, I'd consider it a fluke, but having it happen on both a 12" and a 14", and having read of the others with the same isssue leads me to believe that it is not a unique issue, and is either a hardware or software flaw. Since the advice in every one of these complaints has been rest the PMU and Reset the PRAM, and since this has failed to correct the situation, I'm curious as to whether there is anyone on thes Forums that has knowledge of the problem and a proper fix.
As the issue is truly random and can not be duplicated on demand by manually putting the machine to sleep the "geniuses" have as yet not provided a solution. All I would like is an acknowledgement that there is an issue and that there is hopefully a fix in the works. Even just an acknowledgement that, "it sometimes happens" would be helpful.
Sorry for the long rant, but I keep seeing the same issue brought up over and over again, with the same non-solutions. Any other suggestions or clues would be very much appreciated.
ibook G4 1.33ghz 12, 1.42ghz 14 Mac OS X (10.4.4)

Nothing, No one..... So out of the hundreds of thousands or perhaps millions, of iBooks sold in the past year, I somehow managed to snag the only 2 that display this problem. Those odds are staggering. A 12" 1.3G4 and a 14" 1.42G4, purchased two months apart. Both in the original factory state, and they both display the same sleep issue, and yet somehow this is unique to my experience.
The sarcasm is intended, and after having to do a forced restart, and then wasting an hour running tech tools to make sure there are no disk issues for the third time this week, this is getting old. I'm not asking anyone for a magical fix, all I'd like is confirmation that the issue is being investigated and will hopefully, eventually be resolved.
Thank you......

My macbook won't wake up from sleep

I've seen various threads suggesting resetting SMC and removing unneccessary networks from Airport, but these have no effect on my machine.
I can make the machine sleep easily enough by closing it or using the menu, but it won't wake without the 10 second press of the power. When it does come back it it counts through a progress bar like a PC! How embarrassing. Then, usually, it crashes completely and requires a restart.
This only started happening after I plugged in an iPad for the first time (iPad 1) and initiated it through iTunes. However, the same night I installed a demo version of Pagesender. Any suggestions gratefully received.
Thanks.

I have the same or a similar problem with my MacBook Air (MBA Mid 2009).
It goes to sleep when I close the lid as you would expect, but when I reopen it nothing happens.
I have to press the power button (I don't have to hold it down, as you apparently do) to turn it on.
Then my MBA (as it always has done when waking from deep sleep) shows a progress bar running from empty to full.
However, just before the full mark is reached, the screen goes black and the MBA does a hardware reset.

MacBook won't "wake up" from sleep mode since downloading Mavericks.

I have a 2008 MacBook and since downloading Mavericks, I've had a lot of issues when the computer is in "sleep mode." There are many times where it won't wake up and just remains a black screen. I'm forced to shut it down and turn it back on. When I do this, I have to login and it reloads everything I had had opened when it was put into sleep mode. Help! Thanks.

I have the same issue with my Macbook Pro 2.4
Have you by any chance installed a new RAM?. I've just added new 8 GB RAMs & I noticed the issue afterwards, but I'm still not sure if it's the cause.

MacBook won't wake up from sleep and Bluetooth Settings (Possible fix)

Hi,
I rest my SMC as per the instructions. I've done this a few times before and it my system sleeps one time correctly then glitches as previously noted. However, this time I did not use any Bluetooth device but I was connected to the internet via my wireless router. The computer has successfully entered 'sleep' and woke up several times without a glitch (white light flashing in front during sleep).
I the tried various Bluetooth settings starting with switching ALL the choices listed under the Bluetooth Advanced tab to off. I then switched on my Bluetooth mouse, used it for a while then I switched off the mouse (Microsoft Notebook Mouse 5000) and waited for the laptop to give the 'lost connection' notice. Once the notice disappeared I close the lid and the system entered sleep again (white light flashing in front) and woke without a hitch.
Next I restored the default Bluetooth Advanced tab settings including the ‘Allow Bluetooth device to wake system’, reconnected the Bluetooth mouse and used it for a while before closing the lid and placing the computer in sleep mode. I left the mouse on. Something very interesting happened…….the system properly entered sleep mode with the front white light flashing, I then intentionally moved the Bluetooth mouse and the system tried to wake with the lid closed. I saw the Apple logo light up briefly then shut off AND I also heard the Superdrive mechanism respond. The white light in the front of the system stopped flashing and just stayed on. The system would not wake. I had to hold the power button down till the white sleep indicator light shut off the boot the system back up. It is important to note that I DID NOT reset the SMC.
Once the system rebooted I made one change to the Bluetooth Advanced tab settings, Specifically, I switched off the ‘Allow Bluetooth device to wake system’. I used reconnected my Bluetooth mouse by turning it on. Used it for a while then closed the lid. The system entered sleep again (white light flashing in front) and woke without a hitch. The sleep mode works equally well now if I close the lid or select sleep from the menu.
I realize this may not help everyone but it has aleviated this problem, at least for the present on my system. I hope this helps some folks as well as the Apple techs.

Hi,
Just an update, it has now been one week since I modified my Bluetooth setting as per my post above. The computer is still going to sleep and waking without problems.

MacBook won't wake up from sleep

When I fold my MBP, and later flip up the screen it won't wake up.
I have to force close it, and then press the powerbotton to start up.
I have reset the PRAM and SMC settings and nothing seems to work.
Does anyone have an answer how to make my MBP wake up every time it has gone to sleep?

Many have reported this problem.
For some the issue was resolved by resetting PRAM and SMC.
Others have taken the MBP to the Apple store.
Apple helped them.
Best.

MacBook screen goes gray and won't wake up from sleep - 10.6.2

We have a MacBook Alum running 10.6.2 with 4gb ram.
We recently upgraded to 10.6.2 from Leopard and this issue started to happen.
It seems that as the MacBook goes to sleep or goes to the screensaver mode, the screen goes gray and won't wake up from sleep or screensaver mode without a hard reboot.
Is Apple aware of this issue? It did not happen with the previous version of Leopard. This issue arrived when we upgraded to Snow Leopard. Other than the sleep issue, SL is rock solid. Kudos to Apple for producing a great OS!

Hi GrooveDaddy,
Have you contacted AppleCare via telephone to make them aware of this issue? It definitely doesn't sound like normal behavior. What sort of troubleshooting have you done so far on the issue? What sort of settings do you have on your screen saver? Password protected? Custom iPhoto slideshow?
What if you manually sleep the machine by closing the lid or engaging it via software (via the Apple menu) does the screen have the issue in both scenarios?

It won't wake up from sleep after I open it. If I close it and then open it, it doesn't wake up for at least 5 minutes.

just upgrade my macbook air to yosemite. now when i physically close the computer and open it back up, it won't wake up from sleep mode. I tried pressing the power button, but it wouldnt turn on. Then once it somehow turned on by itself, I tried a PRAM and SMC reset. Then I tried closing and opening the computer again and I still had the same problem. nothing has worked. when i do get the computer on, i randomly goes into sleep mode again. I've check the settings for display and it says after 45 minutes of nothing it will sleep.

Step 1
Take all the applicable steps in this support article. That's the starting point for any further efforts to solve the problem. Please read the whole article carefully (some of it is hidden by disclosure triangles) and don't skip any of the steps, including the ones under the heading "Additional troubleshooting." If you don't understand any of the steps, ask for guidance.
Step 2
If you're running OS X 10.8.5 or earlier, from the menu bar select
           ▹ System Preferences... ▹ Accessibility
If the checkbox at the bottom marked
          Enable access for assistive devices
is checked, uncheck it and test.
If you're running OS X 10.9 or later, select
           ▹ System Preferences... ▹ Security & Privacy ▹ Privacy ▹ Accessibility
If any applications are listed on the right and have a checked box next to them, uncheck all the boxes and test. You may first have to click the padlock icon in the lower left corner of the window and authenticate as an administrator to unlock the settings.
Step 3
In the Energy Saver pane of System Preferences, uncheck the box marked
          Put hard disks to sleep when possible
Step 4
This and the next step must be taken as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that heading, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You may see one or more reports with a name that begins with "Sleep Wake Failure" followed by a date. Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
Step 5
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ Diagnostic and Usage Messages
In the search box in the window's toolbar, enter "powerd" (without the quotes.)
You may see one or more lines like this:
com.apple.message.signature: Platform Failure
If you do see that, and you did everything in the preceeding steps, then you're dealing with an internal hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

My mac won't wake up from sleep, what can i do

My mac won't wake up from sleep, what can i do

Can you say more about thermal cut-off? My mac has beene having problems waking from sleep and I have noticed that I hear the fan running ever so slightly in the background. When I depress the power button for a second the fan shuts off.
Just open the side an dlook to see which fan it is. The lower fands are easy to see as well as the video card fan.
When you push the power button and that fan goes off is the machine now fully off? No power light? No fans spinning? Now drives spinning?
I don't recall what I did when my machine shut off with the one exhaust fan running. I think the obvious thing I would have tried would have been to push power button for 10 seconds to shut it down fully. That or actually pull the plug.
When this happens the only way to use my Mac is to restart via the power button.
Then I guess that answers the first question. It must have turned off since pushing the power button again was the normal reboot.
I can't find any helpful info on thermal cut-off so I was wondering if you could explain what it is, what causes it, and more importantly what I can do to fix it?
That was my term for it. What else could it be? Without its fan video card would get extremely hot and throw off all that heat. Whats the point of having temperature sensors in so many places other than to use that info to protect the machine against damage due to overheating? So my assumption was card gets hot, sensor (probably the pci slot 1 temperature sensor) senses it, kills the machine. It's also seems logical to me that the circuit(s) handling temperature overloads would want to keep a exhaust fan running to dump the heat out of the machine to further protect any damage from the heat.

G5 won't wake up from sleep & fans go to high speed ???

G5 won't wake up from sleep & fans will go to high speed within a few minutes of it going to sleep. Whether I put it to sleep or it goes to sleep on it's own per my preferences in energy saver. I have to manually shut it down by holding the power button in. I ran the system hardware dvd and results were good. I have repaired permissions, reset the PRAM.
Any ideas?

"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, test sleep in Safe Mode, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Won't wake up from sleep mode

I have only had my iMac for a couple weeks and four times now it won't wake up from sleep mode. I have to use the on/off button for a response.

Since you have a new machine, I would call Apple immediately and have them deal with the problem.
