OS X Lion 10.7 Sleep Issue

Installed Lion this morning and the only issue that I have found thus far is sleep.

I use an external display as well as the laptop display. When I close my MacBook lid and wait several minutes, I do not get the sleep mode winking LED and my second display does not go into standby, probably because the Mac has not entered sleep mode.

When I raise the lid, my laptop display appears to have been in standby and the Mac looks to be doing a device discovery. After the discovery, the Mac display is normal but all the apps from my second display are now on the Mac display.

Anybody have a clue as to the cause or is Lion just broke?

Cheers

MacBook Pro, Mac OS X (10.7)

Much thanks to ADub128 for this post earlier in this thread. The instructions below worked for me.

Called the tech support line and this is what ultimately worked for me. Caveat emptor:

1) Trash this folder

Macintosh HD > Library > Preferences > SystemConfiguration

2) Re-boot

3) Now sleeps and wakes OK (so far!)

4) Empty trash

Does this also work for the "two monitor" issue? Or just for other issues mentioned by people in this thread?

Thanks!

I clenched my teeth and deleted the Macintosh HD > Library > Preferences > SystemConfiguration folder.

The system reconfigured itself though I had to redux my network stuff.

I have a two display system and when I closed the MacBook Pro lid, BAM, what was on laptop display moved over to second monitor.

Conclusion: Deleting the folder on a two display system does not reslove sleep issue.

Thank you for this idea.

My iMac 27'' i5 (2009) doesn't go to sleep, too.

I try deleting this folder this evening .... I really hope it'll work... :-/

I've been following this thread for 3 weeks now and I finally figured out how to resolve the issue:

Find a gun.
Shoot yourself in the arm.
The agonizing pain and threat of bleeding to death will make you forget that your computer doesn't go to sleep automatically.
Go to a hospital.

Sleep never occurs

This sounds like a perfectly logical feature to me. You connect a large screen to use it. By closing the lid on the Macbook you could indicate you would want to shove it under the big screen, under a pile of papers or whatever. It would make perfectly good sense to make the situation you describe the default.

A whole other question is whether the OS would let you configure the system to do what you want.

My $0.02...

Gerard,

In your posting, if you would change the word 'feature' to 'option', I would agree with you.

However, since you would no longer have access to the keyboard, an external one would be required if needed to key in anything.

Apple needs to make this an option like (I really hate to say this) Windows does, 'Upon lid closure do this...'

English not being my native tongue, forgive me if I said anything wrong. It sounds like I meant what you are saying. And indeed, I am using a bluetooth keyboard when the MBP is on my desk.

Gerard,

Your english was fine and you said nothing wrong.

I merely wanted to point out that the capability you mentioned as a feature, probably was in your case but not all of us would prefer that as a feature. To allow fexibility in what happens when the laptop lid is closed, your feature should be an option so the rest of us can get back what Lion took away.

Cheers

Ah, I see. We're on the same page. That's exactly what I meant with: "A whole other question is whether the OS would let you configure the system to do what you want."

You want an OS builder NOT to take away things from previous release, anyway, not without the possibility to restore them (like the gestures etc).

WMR, I've got the same issue as you. As long as Mail is running my iMac won't go to sleep automatically. I can Apple->Sleep and it works fine. Shutdown Mail and auto-sleep works like a champ, even with Safari and Widgets running. For me, and apparently you too, it's something with Mail.

This night my iMac did not go to sleep - allthough it did last evening ... and I did not change anything.

Two possible reasons (I guess):

- Mail is active

- iPhone is connected

This is shown in Konsole - any ideas, what it means? -->

I have done what I used to do in my old Windows times and solved all the problems at once: I did a clean install of Lion and everything is back to normal. My Mac sleeps with Mail running, my Time Machine takes a very short time for backups...

I tried everything mentioned in the discussion forums and everything Apple Support suggested but nothing helped. I hate to say it, but the only thing that helped was to format the HD and to do a clean install of Lion. Very time consuming for me and it reminded me of my old Windows times.

Is there any piece of documentation from Apple which confirms that it is a feature that an MBP with secondary screen does not sleep when the lid is closed?

Aug 27, 2011 2:13 PM in response to eezacque

The computer remaining awake with a closed lid when a second monitor is attached has been a function of OS X for quite some time now, but here is the KB on it http://support.apple.com/kb/ht3131
