Macbook Pro waking up when put to sleep

I have an iMac (2.66 GHz, 4 GB RAM) and I have the identical problem. When I would tell it to sleep, it would wake up several times during the night. I have always had "Wake for network access" turned off in the System Preferences. The only things I have connected are an external hard drive for back ups and a printer. Both of these are powered off when they are not actually in use.

The problem has shown itself with various pointing devices, so I don't believe that is the reason. I have seen it with an Apple Mouse, a DH Products Trackball, a third-party mouse, and now an Apple Magic Trackpad. Prior to the trackpad, Bluetooth had never been turned on, so I doubt that is related, either.

About a month or two ago, I installed SafeSleepOnce. At first, this seemed to help, but it is doing it with that, too. Until today, when I installed OSX 10.6.8, it had done this with 10.5.8, 10.6, and every upgrade since. I have little hope that 10.6.8 will be any different.

Because the internals of the iMac are very close to the laptops, I suspect this is an unresolved hardware problem. It's hard to understand why Apple has not done anything about this in the several years it has been happening.

Well, it might be an incompatibility (HW-SW) issue with the updates that have introduced the AppStore. In fact, until the 10.6.5 - in my case - I have not encountered any problems ever! Of course, it is not a problem easily solved.

... with Lion resolved? Has anyone tried it?

I won't be updating to Lion for a while. I can get it for free through my school, but the school usually waits a few months to make sure there are no big bugs in the OS and to make sure it is compatitible with the school's other software before distributing it.

Also, my friend with the Macbook pros purchased around the same time as I bought mine is in China until end of August so I haven't been able to talk to her yet.

Do you have news? I have not solved yet!

i'm also seeing this. wake reason EHC2. have apple aluminum keyboard, with kensington optical mouse connected to it. MBP will consistently immediately wake up from first Sleep attempt (apple menu or cmd+opt+eject), then always succeed on the second. after rebooting last night, sleep was successful on first attempt. will keep monitoring when normal state goes bad again.

I discovered that if I connect, with USB, an Apple keyboard, it always goes to sleep even with the 10.6.8; at this point I think it's a defect in the integrated keyboard of the MB Pro or in the Logic Board. I'll take it in for service.

I had the same problem with my MBP waking from sleep and getting very hot overnight. My wake reason = EHC1 (USB port may have caused Mac to wake from sleep). I tried all of the stuff mentioned in the other posts and nothing worked (e.g.-SMC reset, making sure nothing connected to USB ports, turned off all wake from sleep options, etc). One person had mentioned that Candleair may be the problem. I deleted the Candelair driver and that fixed my problem. There may be a host of reasons that this occurs, but this was the issue with mine. Good luck!

Seemingly, on the chance I use macs sleep keyboard command while this macs setting in energy saver pref. is set to "Higher Performance", this mac seems to sleep after an initial sleep command

Possibly disregard my prior comment, seemingly ocasionally this method doesn't work.

A method i found which does work is i created an app using applescript editor which i put on my dock which is a sleep button. this works every instance i use it.

tell application "Finder" to sleep

save as application

i put this application on my dock

This problem danced around my nerves for quite an extended duration of time, so i just caved in and let it purr with screen saver set to display nothing, abstaining from sleeping the computer.

To extend the keyboard cable underneath my behemoth desk, i plugged the end of it to a power boosting USB cable and into the computer just before going on a vacation.

Vacation comes and i unplug the computer from the power at the computer end only, and reverse course at Vacation's completion. Some hunch tells me i surged the RAM modules..just pure speculation here, given that i used the power extending USB cable in the car for our trip, and could have, could have reconnected it when our trip was over in an way not coordinate with a perfect conception of physics..

Be it as it may, the computer now started going to sleep on its own from wake parleying away from my own not so brilliant previous solution.

No Bluetooth in use on this iMac. Ethernet cable used for outside connections. No other USB peripherals, Firewire 800 backup hard drive in place and not used/unplugged since problem appeared. Network Settings in System Preferences has all other looming choices for outside connections disabled from the list on the left that once included Bluetooth, Firewire, Wifi,…. etc. Running OS X 10.8.5 Supplemental Release.

This time around i had limited patience and jumped into the fire of Terminal commands. The Terminal application is in Desktop -> (Double-Click on HD Icon) -> Applications (From Menu on Left) -> Utilities

The only thing that i recommend is to put a Mac, any Mac built after 2005 into Hibernate mode if you don't mind the extended wooziness of a wake up, post-Hibernate and if you can assure yourself that you will resist the temptation to catch a whim, a moment of tangential brilliance or what have you, of something you want to then look up on your favorite search engine only upon hibernating the computer. I know it happens to almost, almost all of us. :-)

Power button hibernates, power button wakes up from hibernate.

The terminal command is as follows:

sudo pmset -a hibernatemode 1

Be sure to enter it in Verbatim, or your Mac just might be very disagreeable afterwards.

I have had no automatic Self-Wake Ups or automatic Self-Hibernate issues since.

Note: I have let the computer go without hibernating occasionally and let it drift off into Screen Saver, and the problem reoccurs, but when it sleeps in this incarnation, it does just that, sleep, not hibernate, until you initiate hibernate on your own, as stated above.

Good Luck!

Update:

Taking the long way home with this issue as i outlined above, ended up clearing the path for the future which was back to the computer's base level operations. At least for sleeping from wake, if you don't mind the power consumption associated with that. A mild trade-off, for many coming here.

I swapped out the power boosting USB extender with a standard Apple one i scrounged up. That's number one.

Then, i afforded a period of 40 hours straight with the computer in hibernate, first having restarted after implementing the Apple USB extension.

That's it.

Steady Purr of the Fan ensued.

I have an inkling that all of you who have the opposite issue, waking from sleep, might just be able to rejoice as well if you follow all the little tinkerings i got lucky with here and in my above post. Who knows, Give it a try!

To put the computer back into sleep mode, please follow the below Terminal command line, appropriate for your given machine:

(Standard Sleep; For Desktop Macs) =

sudo pmset -a hibernatemode 0

(Safe Sleep; Default for-Laptop Macs, Manufactured After 2005) =

sudo pmset -a hibernatemode 3

Once again, type these in Verbatim. Then follow that up by pressing the Return button.

Enter in the master administrator password for the computer. Allow Terminal to do its thing.

Type in 'exit' as the final step. Press enter. Terminal will now say you are logged out. Quit Terminal.

Done.

Good Luck!
