Mac OS 10.7.3 Sleep problem

I have a sleep problem with my 2011 Mac Book Pro since I upgraded to OS 10.7.3.

Although it is officialy sleeping, the disk keeps turning and the waking time is too fast just as if it was not really sleeping but just drowsing.

And then the machine wakes up, it looks normal for a few seconds and then turns to a black screen and freezes. The only way to solve the problem is a hard reset. I also notice that my machine has sleep problems.

My machine never had a problem before

Any idea ?

Mac Book Pro, Mac OS X (10.5.8)

Hi there,

I was having the same problem with my MacBook Pro and seem to have resolved it. I must admit I was cursing Lion up and down because of it too.

I found another support thread and there were two things recommended:

Perform a PRAM and NVRAM reset. Instructions can be found here ( http://support.apple.com/kb/ht1379 )
I tried this and while I'm sure it did something it did not work for me.
Perform an SMC reset. Instructions can be found here ( http://support.apple.com/kb/ht3964 )
- This did work in my situation.
- If you look through those instructions and get lost the actual "How To" is at the bottom. Since you have a MacBook Pro you cannot remove your battery so you will want the second set of instructions that reads >> s:"Resetting the SMC on portables with a battery you should not remove on your own

This seems to have resolved my issue for now. I seem to have these shenanigans happen more often once I do some kind of firmware upgrade. However I have been having sleep issues since I upgraded to 10.7.

Hope this helps... Please reply if it does/does not so others know if this was the solution ... or Apple can maybe have a better look.

PS: If this goes beyond what you're comfortable doing there's always the Genius folks at a store ( if you live around one 🙂 )

Hi,

Same problem with Lion 10.7.4 on a recent MBP. The solution provided by "glock22ownr" worked perfectly. I hate to think how the Mac display would have reacted to his 22-caliber Glock had the solution NOT worked. ;-)

In predictable computer-environment thinking, though, I now ask myself WHY the problem came up in the first place, or if there might be some inherent fault in our MBPs which made them "forget" how to do something that they were doing perfectly well before... Lion 10.7.4 has been running on this machine for a while, why would this sleep problem creep up now?..
