MacBook Pro does not sleep when display is closed??? (occasional problem)

Sometimes when I close my MBP display and put it in its case I find after coming back to it that it has not gone to sleep and the fans are running full speed. This has only happened twice (but still twice in two weeks is pretty bad), and it wasnt away for long but I can imagine this being VERY BAD for the computer.
Has anyone else had this problem???

This is worrisome.
I have the same problem. Several times I've closed the lid, put it in my case, and head home. When I get the computer out it can be piping hot. I'm worried that this may damage the machine, or even start a fire.
This is a new MBP. I've made no changes to power management settings. Since this happens frequently, I've tried closing the lid, unplugging everything and waiting a minute before moving it and putting it in my bad, but I still get the problem. (I even stare it at really hard, willing it to be asleep -- to no avail.) Of course, I shouldn't have to go through The 17 Steps of Putting a MacBook Pro to Sleep. I should simply be able to close the lid, unplug, throw it in its bag and go. Or maybe I'll unplug first, etc. It should be able to handle any normal scenario.
I may have to return this computer.

MacBook Pro does not sleep when lid closed

Hi there. I recently upgraded my MacBook Pro from Snow Leopard to Mountain Lion. Before the upgrade my mac would sleep automatically when the lid closed. However, ever since I've upgraded, when I close the lid, my mac doesn't go to sleep. However, if my mac isn't plugged in (running off the built in battery) it goes to sleep. I looked through system preferences and I can't seem to find any settings relating to this, does anyone have any suggestion on what's happening and how I can fix it? Many thanks in advanced.

Test after each of the following steps that you haven’t already tried: Step 1 Apple menu > System Preferences > Print & Scan > Open Print QueueCheck all printers for unfinished jobs. Deal with any you find. Step 2 Apple menu > System Preferences > Energy Saver > Power Adapter > Wake for network access: uncheck. You may need to unlock the preference pane by clicking the lock icon in the lower left corner and entering your administrator password. Step 3 Apple menu > System Preferences > Energy Saver > Schedule > Start up or wake: uncheck. Step 4 Apple menu > System Preferences > Sharing: uncheck all boxes. Step 5 Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable. Step 6 Launch the Activity Monitor application. Select All Processes from the menu in the toolbar of the Activity Monitor window, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately. Step 7 Reset the SMC. Step 8 Boot in safe mode and log in. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you clickLog in.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal. Don’t launch any applicationsat first. If sleep still doesn’t work properly, back up all data and reinstall the OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested. If sleep now works as expected, go on to the next step. Step 9 Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way. Step 10 If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment. If you still have the sleep issue after booting out of safe mode, post again.

My MacBook Pro does not sleep when it should

MacBook Pro is set to sleep at 11:00pm. Often it does not; occasionally it does. It is also set to sleep after a certain period of time, like 30 minutes. It never does.
10.6.8.
Any thoughts?

Then they need to fix it again on their dime. call them up, let them know and have them schedule a genius bar appointment for you.

MacBook Pro will not sleep when charging and display is closed.

Hi,
My Mac will not sleep when it is charging. When I close my display, it will not sleep.
When I unplug the power cable, it sleeps...
I've tried to reset the SMC, and I think i did, the charger went from green to red etc different colours..
Does anybody know what this might be?
thanks

AIGHT GUYS!
This is how to fix it, and i guarantee u its 90% the cause.!
first of all, if you are a lion user (most likely all of you with this problem) go to system preferences, and then to sharing. turn all sharing OFF. especially printers....
open a terminal, and type in :
pmset -g assertions
This will show u if somehting is preventing ur mac from sleeping. on the left colomn, it should say "PreventSystemSleep" and on the right colomn a number. mine was one, which is probably the same for you guys.
Go to system preferences > Print & Scan > Open Print Queue. Make sure all the printing queues are empty and nothing is in there. You do not need to pause any or anything like that just make sure nothing is in the queue.
Close your macbook lid and look at ur light it should be sleeping. HOPE THIS WORKS FOR U
took me long enough to find out.
dont hesitate to ask me any questions

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.

MacBook Pro does not boot when 'cold', Windows 7 on the other hand boots without any problem

Hey everyone,
I have a strange problem with my MacBook Pro mid 2009 13" running OSX Mavericks. For more than a year I have trouble booting my laptop. A 'cold' start (a fresh boot) usually ends with the prohibition sign on a grey back ground (starting in verbose mode results in the error message that the main drive could not be found). So far so strange.
I have Windnows 7 installed as a bootcamp partition. If I start the laptop with Windows booting is no problem and Windows runs smoothly (what a terrible world we live in). If I let the laptop run for let say 10 minutes and restart the laptop Mac OS starts without any problems. (It doesn't work if I immediately restart after windows booted; also reinstalling Mac OS as a clean install from an external medium did not change the problem; disk utility always finds something to repair but neither discpermission repair nor disk repair got rid of the problem).
As an additional comment a WD 500GB Scorbio Blue replaced the original hard drive about a years ago. I had no problems with the hard drive initally and I can't really believe that there is a problem with the hardware, I mean, why does Windows start and Mac OS doesn't?
Thanks for your time and help!
Marco

This isn't a direct answer to your issue but have you considered installing Wine so you can run the occasional windows app directly in OSX? It's a much more elegant solution IMHO. This avoids restarting all the time with Bootcamp and avoids crashing all the time (and the security risks) with Windows running.

Wifi on Macbook Pro does not work when Windows laptop connected

Does anyone know why this is the case or how to fix it? My wifi works great until my wife turns her windows laptop on and logs on the to the wifi. At that point, mine does not work until she shuts her computer down. Any ideas?

you both probably have the same IP address....
set your laptop to DHCP or type in another IP address...

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!

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!

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.

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!

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.

MacBook Pro does not go to sleep when power cord is connected

Hi Experts,
I have recently discovered that my MacBook Pro (2009) with OSX Lion does not go to sleep when the power cord is connected. It does not matter if I close the lid or select sleep from the Apple menu. All that happens is that the screen is powered off, the SIL is solid and I can hear the HDD/fan. I have not changed any of my power settings recently and it has not been a problem previously. If I disconnect the power cord the MB goes to sleep as supposed to (the SIL led starts flashing).
Doing some research I have found other users with somewhat the same issues when VMWare Fusion is installed. I have done some further testing and it seems that if I disable the virtual machine's Network Adapter and quit VMWare Fusion the MB goes into sleeping mode when the lid is closed even with the power cord connected. Enabling the Network Adapter again prevents the MB to go into sleeping mode when the power cord is connected. This even applies when the VMWare application is shutted down.
My guess is that the Network Adapter somehow prevents the MB to go into sleeping mode. The workaround is of course toggling the Network Adapter on and off but the virtual machine has to be running in order to do so. Not being that familiar with network settings on a Mac is there any other way to get around the problem?
Thanks in advance :-)

To anyone,
I have turned internet sharing off but the Ethernet box remains checked. If I uncheck the Ethernet box, the Internet Sharing bubble turns red, however when I close System Preferences and re-open, the box is automatically checked although Internet Sharing is off. Because of this my Macbook Pro will not sleep properly.
All other sharing items are turned off. Only Internet Sharing continues to automatically show Ethernet as active from a Wi-Fi connection.
Any advice?

Why does my macbook pro "goes to sleep" when charging?

Why does my macbook pro "goes to sleep" when charging? It is working fine without charging but once I attach the charger to my laptop, it just blacks out or goes to sleep mode and I can't wake it up unless I unpluck the charger.
I read from threads that it is a logic board problem....How do I solve this problem?

Try an SMC reset. Follow the method for "a battery you should not remove yourself."

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.

I am a windows user that has converted to Mac and loving it but when I updated to Lion my wireless internet dongle would not work anymore and the Macbook Pro does not recognise the device at all so I am unable to reinstall it again. Any ideas
