Computer not going to sleep when lid closed

My wife's new MacBook Air has a couple of problems we can't figure out. First sometimes the computer is not going to sleep when lid is closed and when we lift the lid everything is frozen.
Second, the user Library folder is not seeable in her user account. I know it's there because on the side bar there's a short cut to Preferences folder which we can open.
Strange behavior.
Thanks,
Ron

Ron,
The user library folder (~/Library/) is hidden by default in Lion. I assume Apple doesn't want people mucking around with the sensitive files in there. So this is normal behavior.
As for the freezing issue, I would suggest you reset your power management and perform a safe boot to clear out caches. You should also see if the issue persists after disconnecting USB perhipherals.
Here's how:
Power Management:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Safe Boot:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

How can i get my macbook pro too stay on and not sleep when lid is closed?

how can i get my macbook pro too stay on and not sleep when lid is closed?

If the machine is asleep, lid closed, and you plug in to an external monitor and an external USB keyboard, the machine will wake, anbd reconfigure the screen resolution for the external monitor, Once it has made this configuration change, you can open the lid and it will continue to address only the external monitor. At least that's how my early MacBook Pro unibody 13" works. It seems to run a bit cooler this way. It gets quite toasty with the lid closed while doing anything demanding and you are more likely to hear the fan come on. I have not seen any temps that would cause alarm, but I do get a high speed (6000 rpm), noisy fan sometimes with the lid closed, .
If you operate in the open-lid, external monitor only mode, if you deactivate the monitor for any reason, when it reactivates it will be running both screens, with all the navigation hassles this entails, so I generally set it not to deactivate the screen when in this mode.
Thus I agree with those who say that some of the cooling air is drawn in around the keyboard, the difference in cooling performance is observable. If you activate istat pro, get the computer hot running in clamshell mode, and open the lid, you can watch the CPU temp drop by a few degrees C within a couple minutes. It isn't a huge difference, but enough the lower the fan speeds.

Macbook Pro running 10.6.7 won't sleep when lid is closed

My 2.2GHz 2007 15"Macbook Pro no longer goes to sleep when closing the lid. The laptop continually tries to wake, with the apple logo lighting up, along with the sound of the slot cd/dvd drive. If I leave the lid open, the laptop appears to sleep but the laptop sometimes seems to get very warm and if not plugged in will drain the battery down to nothing. The battery was replaced in the last 4 weeks but the problem existed before the battery change.

This exact thing happened to me. Resetting the SMC solved all my problems. Here's a link to how to do it: Intel-based Macs: Resetting the System Management Controller (SMC) Hope it works!

Computer does not sleep when lid is closed

Hey everyone,
Until about 15 minutes ago I had my powerbook G4 set to sleep whenever I closed the lid. Well, now it does not want to.
I installed a screensaver and used it for a little bit, and now uninstalled it.
The problem is, ever since installing and selecting that screensaver my computer won't sleep when I close the lid.
What is the process to restore this and get it so that it sleeps when I close the lid?
Thanks in advance!

MacBook Pro won't sleep when lid is closed and battery lights won't work?

I have a 2010 MacBook Pro 15" and ever since I got it, the battery indicator lights wouldn't light up (not that big of a deal) and the computer wouldn't sleep when I closed the lid.
I've reset the NVRAM/PRAM, the SMC and verified/repaired my hard disk as needed. But the computer still won't sleep when I close the lid (regardless if the machine is plugged into a charger or not). Is there a known fix for this problem? I've been searching through the forums and troubleshooting from advice that other people have suggested, but nothing seems to be working. Any help is greatly appreciated!

Screen replaced on 17in--now PB will not sleep when lid is closed

I recently replaced my screen to a glossier LG Philips lp171w02 screen. My problems are that my pb will not go to sleep when I close the lid and the brightness keys also are not functioning. Any help would be greatly appreciated.

Is there a way to non-destructively remove this magnet from my 17" PowerBook (older one with 1440x900 display)? I don't like that my PowerBook sleeps when I close it, and I've asked Apple if there is a way to disable this functionality. Short of plugging in an external display, they told me no.
This option is built in to the Windows OS, and I've grown quite accustomed to putting my laptops to sleep manually. I'd really like to be able to have the lid closed and still let programs run, downloads continue, etc.

MacBook will not sleep when lid is closed

I just noticed in the last few weeks that whenever I close my MacBook it will not go to sleep. I've had it only a year and protect it like a baby so I'm not sure what happened (maybe a recent update is buggy).
I've done some research and it seems that there are some problems with MacBook Pros but not so much with MacBooks.
Is there anyone out there that is having the same problem or has had the same problem and has fixed it?
I've tried reseting the SMC and PRAM and repairing the permissions...any other suggestions? I don't feel like going down to the Apple Store unless my baby is in immediate danger.
Thanks

Console.app will allow you to check various logs. The root system one should be reflecting any major issues, though be aware the description may not be in plain english.
Another issue I found is that certain classes of USB storage devices can wake the mac back up immediately after it sleeps on lid shut, especially external multicard readers (sd/mmc combo etc). If there is any USB equipment, try unplugging it all first before closing the lid and see if you have a different outcome.

Latest Update does not fix Sleep when lid is closed.

I updated my Macbook Pro Retina with latest fix for Sleep + Nap. Today on my way to work, I closed the lid of the Macbook Pro, and when I got into the office, I took it out my bag and it was running extremely hot! I was surprised, as closing the lid should put it to sleep and not consume so much power. This is extremely dangerous for such an expensive laptop and should be fixed asap, this is unacceptable Apple, please fix this asap.
I run
OSX Mountain Lion 10.8 (All UPDATES are installed)
Parellels
Carbon Copy
Diablo
No other custom software.

Alum Powerbook 1ghz Does not Sleep when Lid is Closed

Hi,
I have a 1ghz Aluminum Powerbook with the lower memory slot issue. Everything is working great (besides the memory issue of course), and this one other bug: When I close the lid, the powerbook does not go to sleep. I have to manually select "Sleep" for it to go to sleep. The sleep light comes on and all, but I guess it just doesn't recognize the display lid shut.
The sleep issue is not the biggest thing, but is this a sign of a bigger issue, like logic board failure? Or is it simply a sensor that is not recognizing the powerbook lid shut?
Please let me know. I'm really enjoying my "new" powerbook after selling my titanium.
Thanks!

Hi Steve,
Hmm, the lid problem is interesting - if the Powerbook doesn't wake up from opening the lid, however, then it's most likely a sensor problem, which as you found has an easy workaround. YOu could always go to the Power Section of the System Profiler and seeing if the "wake on Clamshell open" and "Wake on Clamshell Closed" are set to Yes and No respectively. If they aren't those settings, then resetting the Power Management Unit might help, or just reset the PMU and see what happens (info here: http://docs.info.apple.com/article.html?artnum=14449)
As far as I know, (which probably isn't much!) the memory slot issue is just annoying, and probably won't do much damage to your computer. However, (and probably what you don't want to hear!) when my computer suffered the problem 2 weeks ago, I noticed that the memory door seemed to be a little bit warmer than usual and the rest of the computer in general. So I took it to the Mac Genius in the Birmingham Apple Store and they had the logic board replaced. Now, it seems to be running at a normal temperature. But looking back on it now, the temperature change may have been just subjective - ah well, your mileage may vary.

Satellite P50T - does not sleep when lid is closed

I have a new P50T with Windows 8.1. When I close the lid it does not sleep despite
my power options being set that way. I have closed the lid, unplugged and put in my bag
just to find it on an hour later and too hot to touch.
Any information would be appreciated.
Thanks

Similar to this one. Compare wth the spec.

Change that setting, "Restart" Windows (don't shut down), restore the setting, and Restart again. Sometimes clears cobwebs in the registry.

Air does not sleep when lid is closed?

My friend just bought a new 13" Air and it works great except he was confused at the fact that when he closes the lid the laptop does not go to sleep. He noticed this when he closed the laptop in a dark room and the light from the screen was leaking out. Has anyone else experienced this problem? I know on older Apple laptops sleep mode was activated when a magnet in the LCD housing hit a sensor in the upper case when you closed the lid; is this still the case? And if so anyone know where the sensor is located just so I can run a magnet over it to see what happens?

I don't see this behavior at all, but I'm wondering how does he know it's on? When closed the screen virtually seals against the bottom. If the Apple logos lit up? If so then it's obviously on. If not then it's not on.
If it's staying on, it's likely a software problem. Either there is an app or something installed than isn't sleeping or an OS problem. If it really isn't sleeping and no questionable apps have been installed, backing up and reinstalling the OS would likely fix it.

No Fan Sensor Found No Battery Found Doesnt Sleep when lid is closed?

I have a late 2006 model MacBook Pro and this past week the battery doesn't show up on the menu bar, so I cannot see if it's charged or not (except the LED's at the bottom which indicate it's full) but more importantly, according to iStat, there were no fan sensors found, and the fans sound like they are running full speed with no slowdown from start to sleep. And I now have to manually put it to sleep and I didn't change my preferences to do so. Before I spend what would most likely be more than what the thing is worth, I wanted to know if there's anything I can do before I take it to Apple?
I'll take whatever you can offer as I rely on this computer for school, home, and work!
Thank you so much in advance!

Hi b, and welcome to Apple Discussions.
Try an SMC Reset. Also take a look in System Profiler to see what it says about the batt condition. If neither of these help, boot from the install disc with the Apple Hardware Test on it (hold down the d key) and see if it finds any bad sensors.
