MBP suddenly wakes from sleep

Since a couple of weeks (not directly related to a software-update as far as I know) my MBP suddenly wakes up from from sleep. Sometimes it is every 30 seconds, sometimes it occurs only once or twice a night.
I've done a lot of tests and it doesn't seem to be related to specific software running at that moment. Most of the time only Safari, Mail and Messenger are the only active apps. There are never USB-devices connected wen the MBP is asleep, although during 'working hours' there are a mouse and keyboard connected. There are disconnected long before going to sleep.
Almost always the wake reasons (mentioned in the console.log) are:
MacBook-Pro kernel[0]: Wake reason = EHC1 EHC2
but today I saw:
MacBook-Pro kernel[0]: Wake reason = UHC3
I tried resetting the SMC, NVRAM and PRAM but that also didn't help.
Does anybody have a clue what these wake up reasons mean and how I can fix this problem. I see that a lot of people have these problems but so far I cannot find a solution.

Hello, I had the same problem. Today I tried "going to sleep" again and it worked.
The only relevant thing I did today was installing the "iousbfamily327.4.0log.dmg" file downloaded from developer.apple.com (search for "IOUSBFamily.kext 3.2.7")
I initially installed the file "IOUSBFamily.kext 3.1.5" for Leopard 10.5.5 a few days ago. I also had problems when inserting a USB mass storage device (I got a "blue screen").
Now, after I installed the USB debug kit for 10.5.6, my MacBook Pro goes to sleep again. Please write if this solution worked for you!

Mbp randomly wakes from sleep

For some reason, my mbp SR 2.2ghz stock model randomly wakes from sleep for no reason roughly 20 minutes after I put it to sleep. I am about 10 feet from the computer and do not touch it. Auto wake from bluetooth is off. I reset the video ram, ran onyx, and tried everything i could think of. Nothing is plugged in. No programs are running. How do I fix this?

Follow the instruction listed in this thread…
http://discussions.apple.com/thread.jspa?threadID=1077308
… and return the results. There might well be an issue within Mac OS X and or the hardware which needs identifying and this will help Apple identify/comfirm their suspicions.
By the way, if you use a password to wake your MBP from sleep you will need to disable it so your MBP won't go back to sleep.

MBP - Occasional Wake from Sleep Issues

Hey everyone:
I've got a late-2011 MBP running OS X 10.10.3. Occasionally when I close the lid, it will go into a "deep" sleep mode. In a normal sleep situation, the front light will flash every few seconds when it's sleeping and when I open the lid, it'll pop back up either to the desktop or the password prompt depending on how long it's been down.
When it's in the deeper sleep (which has been going only for the last few days), I'll open the lid, the screen will stay completely black, and the front light will STOP flashing, like it's totally dead.
Press the trackpad buttons and/or keyboard. No respose.
Press the power button for a second and the sounds of activity will start. The screen will come up with a blurry version of the desktop background, a password prompt, and an orange checkmark next to my user name. Enter password, some progress happens, and it'll then go to a gray screen and a "normal" password prompt.
Enter password there, then a progress bar starts across the bottom of the screen, and it will eventually go to the desktop and function normally. This whole process takes about 3 minutes from the point that I press the power button.
As an experiment, I decided to close the lid and put it to sleep over and over to try to replicate the problem. It took four tries.
What's happening? I've done some research and read a few articles, but I haven't yet found anything that helps.
Thanks!

Alright, so I found another chat thread that seemed to point out that some people had some wake-up issues after replacing their RAM with new memory from Crucial. On my MacBook, I replaced my factory memory (2X 2GB, Samsung) with some non-branded memory from a private sale, about 14 months ago.
Since some folks seemed to think this was RAM related, I decided to do some swapping. Here's what I found, and again, the problem was when the lid was closed on battery power, it would either go into a deep sleep or hibernation or full reboot to get it to wake up.
2 Factory Sticks - No problem
Replacement stick #1, Factory stick #2 - No problem
Replacement stick #2 alone - problem....
So there it is. The machine operated perfectly normally with both replacement sticks in it. They registered and were shown as 16GB total memory in the system screens. However, this sleep problem was still present.
So now, I've tossed "Replacement Stick #2" and have installed "Replacement Stick #1" and "Factory Stick #1", which totals 10GB and all seems to be well.
Thanks for reading......

New MBP instantly wakes from sleep...any thoughts?

I just purchased a new MBP 15" 2.4Ghz.
Regularly though somewhat intermittently the machine will instantly wake after entering sleep mode.
At first I had an external monitor hooked up, and it seemed to wake as soon as the monitor entered its sleep mode. Without the monitor hooked up it would still wake, but more intermittently. Finally, I tried sleeping the machine without the power adapter, and the wake rate seemed to go down a little more.
I have all the OSX updates and the current firmware.
I've tried a full reboot and resetting the SMC.
Any thoughts?

After looking around the forums a little bit I found a couple topics that talk about a bad lid sensor. I turned off the wake on lid open, bluetooth and LAN options, but still no luck.
The next morning I couldn't reproduce the issue right away. After the laptop warmed up the problem came back.
I took the laptop to the local apple store. Again after the laptop warmed up the computer wouldn't stay slept. The store exchanged the laptop.
Not sure exactly what was wrong, but all that was needed was for the laptop to heat up.

MBP wakes from sleep as soon as ac adapter is plugged in

My MBP recently wakes from sleep after this series of events:
1. Use MBP on battery power
2. Close lid
3. Sleeps (light pulses so apparently sleeping)
4. Plug in AC adapter (while the lid is still closed)
5. Wakes at that moment the adapter is plugged in (while the lid is still closed)
6. Sometimes the MBP recognizes the lid is indeed closed and then goes to sleep itself; other times, the MBP goes to sleep, then immediately wakes, then goes to sleep, then wakes, etc., repeatedly (this happens all while the lid is closed as if it's demented), until I open the lid, wake the system and then close the lid again. Then it will finally sleep.
"Wake on AC change" is set to No (see below). I was wondering if anyone knew how to set it to Yes. Maybe I just need to switch the setting back and forth once.
I can recreate the problem, so I can just take it to the Apple Store and let them figure it out (Applecare is still in effect), but I was just wanted to give it a shot here first.

You don't have the same problem, you have the 'I damaged my Mac by spilling water on it' problem.
it will probably fail.
Take it to an Apple Store.

Automatically wake from sleep when lid closed?

I would like my MBP to wake from sleep when the lid is closed (no external monitor attached) in the middle of the night to initiate a backup to another computer. Is it possible to get the computer to wake up with closed and nothing attached? Do I need a third-party app to do this?
Thanks
Brian

But, that won't wake the computer up if the lid is closed and nothing else is hooked up to it. I want to wake it up in the middle of the night when the lid is closed and it is hooked up to a power supply.

MBP w/R glitchy wake from sleep.

When my late 2013 Retina MBP wakes from sleep I have this horrible glitchy screen flash up before asking me to enter my password as normal, it doesn't cause any problems, it just shouldn't happen. It doesnt' appear however if I close the lid, and open it back up within roughly 5 minutes, it must be left. I am running the latest general release of mavericks. Is anyone else experiencing this? If so any ideas as to the cause?

Try a SMC reset. It controls sleep/wake events among other things.

My iMac has suddenly become very slow to wake from "sleep." Why? How can I fix this?

My iMac has suddenly become very slow to wake from "sleep." How do I fix this and what is causing the problem? Even the mouse wakes very slowly.

Try these basic troubleshooting steps.
1. Quit all app scompletely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
2. Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
3. Go to Settings>Safari>Clear History, Cookies and Data. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

No wake from sleep mode MBP later 2011

On my MBP late 2011 build, with OSX Lion Preinstalled. I upgraded to Mountain lion recently, and all went smooth until I closed the lid to put it too sleep. When I returned, opened the lid, it would not wake from sleep. I have to force shutdown and then boot up. This happpens regardless of on or off hte AC adapter. I have already lost some data from this problem. From the online forums I have seen others with this issues, but have found no resolution. Please HELP!

Well after calling Apple support, they determined it was some sort of software issue., so then i took it to the university tech depot and the tech did all the things i tried (SMC reset, reupdate, etc) and a few other resets (not exaclty sure what he did), but nothing seemed to work.
However, this morning, miraculously, it started working (sleep mode that is). I an not sure still what exactly is going on, but its working for now.

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.

boot rom 4.28f1

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. The restart is very important.
 Good Luck! DALE

MBP Wake from Sleep - VRAM corruption

Just moved from G4 -> MBP. When the computer goes to sleep, ~20% of the time when I wake from sleep (opening the screen), I get a flurry of ASCII like characters that move across the screen forever, only cleared by a hard reboot (maybe a soft reboot if I could see the underlying graphics window, but I cannot).
Any thoughts... my guess is a bad graphics card, anyone else have this problem or have an idea?

I had a similar issue. Wake from sleep sometimes the computer would reload but the screen would simply not turn on...
Just had my MLB replaced for the whine issue and that issue appears to be gone as well...with the MLB, you get a new CPU and GPU as well.

MBP Wakes From Sleep With Lid Shut

My MacBook Pro (only about 1 1/2 months old) wakes from sleep while the lid is shut. I close the lid to put the computer in sleep mode and wait until it has fully entered sleep mode (the white light pulsates). If I then pick the computer up and rotate it some, more often than not it sounds as if the hard drive kicks back on and the apple logo on the top of the screen briefly illuminates. Sometimes I have even noticed that the screen will illuminate; however, the most consistent things I've noticed are the hard drive and logo. This is all while the lid is still closed.
I spent around 1 1/2 hours on the phone with Apple support yesterday with no result. I thought I would see if anyone has an explanation or idea here before I send the computer off to Apple.

Hi again,
your statements that the workaround does not "work around"
on your machines confuses me a bit. It looks like the changes
in the com.apple.PowerManagement file don't produce the desired
effect.
First question: Did you restart your computers after having
applied the changes ? If not, try this first.
Can it depend on the model of MBP (I have the new Santa Rosa) ?
If I save the file as an ASCII file it looks like this:
ActivePowerProfiles = {"AC Power" = -1; "Battery Power" = -1; };
"Custom Profile" = {
"AC Power" = {
"Automatic Restart On Power Loss" = 0;
"Disk Sleep Timer" = 0;
"Display Sleep Timer" = 0;
"Display Sleep Uses Dim" = 0;
"Hibernate File" = "/var/vm/sleepimage";
"Hibernate Mode" = 3;
"Mobile Motion Module" = 1;
"System Sleep Timer" = 0;
"Wake On AC Change" = 0;
"Wake On Clamshell Open" = 0;
"Wake On LAN" = 0;
"Battery Power" = {
"Disk Sleep Timer" = 10;
"Display Sleep Timer" = 5;
"Display Sleep Uses Dim" = 1;
"Hibernate File" = "/var/vm/sleepimage";

(German only, sorry)
And - I checked it just a minute ago - i works ! My MBP
goes to sleep when lid is shut and does NOT wake, when I
open the lid. After pressing a key, it comes to life again.
Regards,
Robert
P.S. Please have a look at the files in the
Library/Preferences/System Configuration Folder.
Is there only one file for Energy preferences or
did your system create another one, when you tried
to change settings via System Preferences ? I saw
this one time a few weeks ago, but I don't know
the exact conditions under which that happened.

Wakes from sleep momentarily upon plugging MBP in.

Whenever I plug my computer in it always wakes from sleep for a few seconds (with the lid down.) My boot drive is an Expresscard SSD, but I don't know if that is the cause of this problem. Does anybody know what the problem could be?

It's normal. You do not have a problem.

Since upgrading to OSX Mavericks, my mbp retina will lose wi-fi every time it wakes from sleep.

When waking from sleep, my default home connection is lost, and it usually cannot re-connect until I turn off and back on wi-fi.

Hi. I'm experiencing the same problem, but it's on a 2007 iMac.
When it wakes from sleep, it does not connect to the preferred network. The preferred network is visible, yet when we select it, it asks for the password again -- which I know it is entered correctly -- but the password is refused. A full reboot is required for it to work properly.
It's an iMac, mid 2007, connecting to a Time Machine, using WPA/WPA2 security. All other devices (eg, iPad, iPhone and an other iMac) do not have this issue.
Workaround: I don't let that iMac go to sleep.
Speculation: It's as if when it wakes from sleep it thinks it a different type of security setting
I have not yet found a proper/permanent solution.
Note: I do have TrendMicro Internet security installed, but it is also on the the other iMac and I have tried it with it off and the problem still occurs, thus I doubt it has much to do with it.
Puzzled,
Mike.
