Sleep Issue - New MacBook Pro

Yeah, just did this, so far so good... we'll see though, this was never ALWAYS an issue for me, only about 40% of the time I tried to sleep it would it wake. If the only down point to this is that you cannot swap batteries while the machine's sleeping then there really is no downside for me.

I tried both sleep modes, it didn't make a difference. I also created a new user with pristine settings, archived and reinstalled the system software with all available updates, and I still get the "reboot on wake" issue. I have tried pretty well everything mentioned in this thread aside from completely wiping the hard drive and installing a fresh OS, all to no avail.

On the plus side, at least the issue is reproducible for me -- put the computer to sleep for at least 30 minutes, then open it up to hear the reboot chime. "Works" most of the time.

Looks like the MBP 2008 is a lemon.

I have the same sleep issue. Found my MBP burning inside my laptop bag.

*This seems to happen when I unplug any USB device "after" closing the lid.*

Just thought I'd add in that I've tried every SINGLE fix on this page, and my unibody MBP still decides to turn itself on whilst in my neoprene sleeve. I open my bag to find it hot and fans whirring. 50% of battery life has drained because of the fans, then it's unresponsive and screen is black.

This is certainly an issue which apple need to address. It shouldn't have happened once, but has now happened a number of times for me, under different circumstances. I'm complaining to apple, again.

We should be able to rely on this pro machine. I find myself itching for my old reliable macbook time and time again.

Did you try the hibernate mode change that Pelirojo Loco recommended a few replies up? So far it has done the job for me.. I will post if the symptoms continue.

Changing the hibernate mode variable is ONLY trying to solve the issue of periodically waking during sleep. NOT any other problem (i.e. not waking from sleep, etc.)

I stand corrected. I really put my system to the test this morning and the waking periodically while sleeping persists.

So setting hibernatemode = 0 did not work for me. 😟

Please Apple address this!

This is my fourth MacBook Pro because the first three all had the sleep issue. When I took the third one back, the genius at the Apple store swapped the hard drive from it to the newest one I have now per my request. Not but an hour after I had it, the Mac woke up from sleep. I was tempted to take it back again to get a fifth one but decided to reformat and reinstall the OS once again.

Since doing this, the Mac has not woke up once. I have been very slow to install everything back like I did the first time I did a reformat and reinstall. I've basically been taking baby steps with software/hardware installs to see if I can figure out exactly what is causing the Mac to exhibit this sleep issue.

At this point, the only thing I have not done compared to the last three MacBook Pro's is plug in my USB mouse and connect my Bluetooth keyboard. Both of these devices would obviously be dealing with the USB bus which would explain the Wake reason OHC2.

I guess at this point the next step would be to plug in my USB mouse and see if the sleep issue occurs. If not, the bluetooth keyboard is next. If everything seems fine, well then, I am completely stumped.

I have this problem too! Super annoying.

I've had my Macbook Pro set to the Hibernation mode 0 for a day or so now, and have put the machine to sleep a lot. So far so good. It sleeps and wakes faster and it doesn't wake back up. I'm still waiting for it to wake up though, since this doesn't seem to work for everyone else... :/

Hi,

thought I would reply to this because it's important apple realise how many people have been affected. I have been having the exact same issue. What I have noticed is that if I leave my macbook sleeping in my room overnight it is fine, but if I carry it while it's sleeping it will wake itself up. I am thinking that maybe movement is what is waking the lappy up?

I think I've solved this problem on my computer by turning off "Allow Bluetooth to wake this computer" in the advanced settings of the Bluetooth control panel.

I found that I would sometimes put my computer to sleep (and then into my bag), and then accidently move my bluetooth mouse on my desk. This would "wake" the computer, even with the lid closed! The monitor would not turn on, but it appears as though everything else did.

Problem seems to be solved, but we'll see.

I had the same problem and just did a software update and everything was normal again. i have no idea what was causing the problem.

Ok this appears to be fixed for me.

I called Applecare and was directed to take my battery out, unplug the power cord, and press the power button for 10 seconds.

This appears to have fixed the problem.

(Note, I never used USB devices or any cards, etc)

I had already installed Apple's most recent software update and am still having the problem with my 2-week old Pro's refusal to stay asleep. I've tested the sleep problem under a number of circumstances including the many good guesses presented so far in this post. I discovered the easiest way to determine if a potential solution is working is to simply select the "sleep" function under the Apple menu. There's no need to close the screen... just wait about 15 seconds and Mac will wake right back up all bright-eyed from its brief nap and ready to get back to work.

Avex7:
The fix only worked temporarily for me. About four days after the suggested reset, the issue resurfaced. Performing a second reset has worked for about two days now, but who knows whether it will last...
