MacBook Pro doesn't wake up from sleep mode

My MacBook Pro (late 2011) with OS Mavericks doesn't wake up from sleep mode anymore. Battery is fully charged and the cable is plugged in. I can still hear the ventilator running, but that's all. I never had any problems, but since about 2 weeks this problem occurs. It usually then woke up after 10-15min, but now nothing happened since 4 hours.
Is there anyone who could possible help me? Unfortunately there is no Apple Store in my area where I could go to.

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 MacBook Pro sometimes doesn't wake up from sleep mode

Dear users, my MacBook Pro (model 5,1 - 15" Late 2008) is behaving oddly since I upgraded to OSX Lion. Sometimes, after going into sleep mode, it doesn't wake up. When I hit a key (space or enter), I see the login screen, but it's not possible to type my keyword. The only thing active is "the spinning beach ball of death", so I have to manually shut down my Mac and start over. This problem (and also other problems) did not happen in Snow Leopard. The only thing that changed in my Mac is the OS; other programs remain the same. I already tried reseting PRAM and SMC, and fixing disk errors. Thanks for your attention.

try running a hardware test and see if you get an error code: http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh35727.html

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.

MBP doesn't wake up from sleeping mode

Since one week I am working on my new MBP. Everything works great and fast, without noise or exceptional heat.
However, there is this one problem: when it has been in sleeping mode for a long time, it doesn't seem te wake up any more. I have to force a restart then.
I can't be more specific on "for a long time". I know there's never a problem waking my MBP up after a few minutes, but there's always a problem when it's been sleeping for (wild guess) half an hour or more.
I experience this problem after putting it in sleeping mode manually and when it has gone in sleeping mode itself.
Does this sound familiar? Any suggestions?
MBP 1.83 Mac OS X (10.4.5)

Thanks for your reply.
I haven't calibrated my battery. Could you tell me how to do this? I have been using the Mac for a few months only and don't know very much about it.
edit:
I found it already. (Should have looked first and not have asked right away.) I have to fully charge the battery and then use it until it is empty and goes to sleep. After that I have to charge it again. That's it, right? I'll try.

Short flickering when the notebook wakes up from sleep mode MacBook Pro Late 2013

Hello everyone!
I have a question concerning the display of my new MacBook Pro with retina display (late 2013).
Sometimes when opening the lid when the notebook wakes up from sleep mode, the display is flickering for like two seconds. Then everything is normal again.
This specially occurs when the lid has been closed for a longer time. It makes no difference if the power adapter is plugged in or not.
Have you experienced a similar flickering with your MacBook Pro?
Thank you in advance!

Hello!
I have the same problem with my late 2012 MacBook Pro Retina. The constant flickering after being awoken from sleep was a minor annoyance for me so I contacted Apple Support.
I shall explain what I have done thus far, and I recommend you follow the same steps as I did to tick off possible causes:
Firstly, I reset my PRAM (http://support.apple.com/kb/ph14222) and SMC (ttp://support.apple.com/kb/ht3964).
The issue still remained so I checked if the flickering occurred in a new user (if it does not then it points to your account having a setting which is causing the flickering - possibly third party). For me the flickering continued so I tested it in Safe Boot (which worked fine!).
I then ran (just to be certain) the Apple Hardware Test (http://support.apple.com/kb/ht1509). All seemed to be OK. So I reinstalled OS X and still the issue remained.
It was then I had an Apple Support person 'screen share' with me and we went through certain folders. My GPU folder had an unusual amount of files so we trashed them and began a restart however this led to a bigger problem; my notebook wouldn't boot (not even in Safe Boot!), so be very weary at this stage, I'm not sure if this was a rare case or we deleted something we shouldn't have. I then had to go into recovery mode to get back to square one.
Back to the initial problem I reinstalled a 'clean' OS X version from recovery mode; this was to determine whether if the data is corrupted on my account or if it's something else; most likely hardware by now even if there was nothing that came up in the hardware test (it won't account for everything). I checked from both a backup of my data and then from a fresh user after reinstalling OS X and still the flickering continued.
It was then a Senior Apple Support person set up an appointment to have my MacBook looked at and possibly repaired (it could be a minor wire causing the problem).
That is the point I am at now, so for my case it seems like a minor hardware problem. If your case is as similar as mine I recommend making an appointment with them to run more sophisticated hardware tests that your own MacBook would not run.
I will comment again when my issue is completely resolved for those who come across this Discussion in the future.
Hope this helps!

My password works fine when I turn the computer on, but when I try to wake it from sleep mode the computer doesn't recognize my password -- the same one I used successfully when I turned the computer on.

My password works fine when I turn the computer on, but when I try to wake it from sleep mode the computer doesn't recognize my password -- the same one I used successfully when I turned the computer on.

Okay, I seem to have solved the problem I posted about earlier. I noticed that the language preference in the upper right hand corner of the screen (between the date and time and the Spotlight icon) had somehow gotten switched from American English to French. When I switched it back to American English, my password worked when waking the computer from sleep mode. I have no idea why changing the language preference would affect the way the password works but that seems to have been the case. I'll post again if I experience more problems.

Gen 4 iPad will wake up from "sleep mode" on its own and stay on till fully discharged, getting fairly hot in the process

Gen 4 iPad will wake up from "sleep mode" on its own and stay on till fully discharged, getting fairly hot in the process

I think I have the same problem. The whole sequence is:
* Put MacBook Pro to sleep by closing lid.
* After some period of time that varies, I notice sleep LED is no longer pulsing.
* The case is VERY hot.
* When I open the lid, the display stays black.
* No sequence of keys or closing/opening lid wakes display.
* Only way to recover is to power cycle.
* Problem is VERY intermittant -- I do not know how to reproduce it at will. AppleCare service had it for a whole week and couldn't reproduce it, whereas for me it occurs once every 1 or 2 days.
Actions:
* AppleCare service replaced the main logic board in early June, but it didn't help.
* I did a clean erase and install, but it didn't help.
* AppleCare service had the unit for a full week in July and couldn't reproduce the problem, so they returned it and it still had the problem.
I have a Logitech Bluetooth mouse, don't know model other than M-RBB93. I'll UNset "Allow Bluetooth to wake..." and will also turn off the bluetooth mouse before closing lid. I'll post my results.
Meanwhile, please let me know if anyone determines a solution!

Pavillion 15 n000sp doesn't wake up from sleep in Windows 10

Since updating from Windows 8.1 to 10, my notebook has lost the ability to wake up from sleep mode.
When I leave it idle but open, the scren goes off but any touch on the keyboard or mouse wakes it up.
If I close the notebook, it goes into a deep sleep mode and unable to wake up. The usb powers off (optical mouse stops working) and pressing the keyboard, touchpad or power button does nothing. If I disconnect and reconnect the usb cable, I regain power to the mouse, but don't gain any functionality. Only way to recover from this is a hard reset by long power button press. I have already followed the instructions at http://support.hp.com/us-en/document/c03383935#AbT0 (basically assuring that peripherals have the ability to wake up the device - not only the keyboard, as stated in the article, but also mouse and touchpad - and checking for updates both through the windows update as the HP support Assistant and going through all devices in the device manager). I have updated both graphical card drivers (Intel HD and NVidia Gforce) and the update assistant doesn't detect any more updates. Still, the issue persists. Any help?

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

After update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.

hello,
after update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.
the used ports appear to be "killed"; the unused USB ports seem to work, but the Mac works in slow-motion.
The only "solution" is to restart my Mac.
- SMC-reset, PRAM-reset or repairing user rights had no positive effect; what is the solution - a bug-fix-update???

I have a mac mini (A1283) with OS 10.7.4. Upon upgrading to 10.7.5 it did not start up again. Instead, the light was on and the hard drive did not start up. The light on the connected USB mouse was not lit.
My solution:
Cold start with Command-v pressed.
This should start Verbose mode (see http://support.apple.com/kb/HT1492 ).
What happened on my mac mini was that the grey startup screen with the Apple logo appeared for a long while before the login screen came.
Maybe Cmd-v set open firmware params and fixed some corruption.
Anyway: my mac mini works again.

My imac freezes , need to restart everytime i wake it from sleep mode. just started happening 2 weeks ago.

For about 2 weeks whenever I return to my imac and tap the mouse to wake it from sleep mode my screen is frozen. I have tried to wait for it to unfreeze but it doesnt wake. I cannot get any results from using the mouse or the keyboard. I always have to hard reset the computer to be able to use computer again. My mac is a year old. Anyone have any thoughts as to why tis is happening? Thanks

If you have more than one user account, these instructions must be carried out as an 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.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

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.

X1C won't wake up from sleep mode using keyboard

Hi...so finally got my X1C today. One thing I am noticing is that the machine won't wake up from sleep mode when I press any key on the keyboard -- it only wake up by pressing the power key. This is a bit unexpected to me. Is it by design, and is there any way to change this?
Thanks for your help.
Solved!
Go to Solution.

Does it awaken from stand-by if you press the Fn key? That's been the ThinkPad standard for as long as I can remember.
