MacBookPro doesn't go to sleep when close screen

I just upgraded MBP 2.16GHz Intel Core Duo to leopard. Everything went fine, except, when I close the screen Leopard does not go to sleep. When I open the screen, however, it just stays on a black screen, but the keyboard lights up in the dark so I'm pretty sure it's processing - just without showing the screen. If I close it again for a few seconds THEN it goes to sleep and I can wait a few more seconds to open it up where I was before. Obviously this is a bug. Is anyone else experiencing the same problem? Solutions?

If you have issues like that (my MAcBook did not want to go to sleep while it was connected to power...)
what you can always do is power up the 'Terminal' and then punch in 'pmset -g assertions'. That's shoing you which application is holdng your mac back from sleep.

Monitor not going to sleep when close my lid to MacBook Pro

Hi. I was wondering if there was anyway that I could get my Dell E173FP monitor to sleep when I close the lid to my macbook pro. I do not have it on mirroring mode. When I close the lid to my laptop it will just switch my desktop to the monitor instead of the monitor going to sleep with my macbook. When I press the power button and click sleep or go to the apple menu and click sleep it will work though. This really irritates me and I would like It to sleep when I close the lid instead of having to do more. Please help.

Sounds like the system is going into Clamshell mode. Here's some info on that mode.
One workaround would be to disconnect line voltage as that's required for clamshell mode, there may be others.

Prevent sleep when close display?

I am using an external monitor. How do I prevent my MacBook Pro from sleeping when I close the display?
I do not use an external dock.
Is there a reputable external dock?

I agree, this needs to be a topic for all laptops from Apple.
I also need a quick, non-hardware way to accomplish this.
It seems it should be (at it's most complicated) an option accessible through Terminal or System Prefs, but it appears that it's not.
It really should be built into the OS, to auto-recognize that the OS is running on a laptop, give the option to the user (through system prefs, to have a one-click switch icon in the menu bar, to cause "No-Sleep on Lid Close", when activated.
I would call this function "Brooklyn" as in No Sleep til Brooklyn. It should also add the ability chose whether or not the screen comes on, and/or the computer wakes, upon opening the screen.
The track-pad mouse-button should also come default set to menu-click (right-click) when there is a finger on the trackpad, but this should be built into the OS, and it should be a preference setting. Otherwise, they really need to add a seperate button. Menu-clicking is just to useful.

Macbook pro doesn't go to sleep when I close screen

Okay so, I don't know exactly since when this started occurring, but whenever I close the screen of my macbook pro, it looks like it goes to sleep. but it doesn't. then when I open it back up, the fan goes up to 100% and the macbook is all warm and whatnot. Basically what I think, is that it doesn't actually go to sleep. maybe this has to do with the powernap function?
I don't really have any other problems afaik.
anyone else has this?

Macbook pro doesn't go to sleep when screen lid is shut

Hi, I've got macbook pro late 2008 model with glass trackpad. When i got it was working fine and everytime i shut the screen lid, it would goto sleep like normal macbook pro does. Recently its not going to sleep at all. I've to put it sleep to by clicking apple logo on the corner and then choosing sleep. I know its a minor thing but I want to fix it. I bought a new charger sometime ago but that doesn't seems to be doing anything to macbook pro or does it?
Thanks

I've tried SMC reset and nothing happened and PRAM reset says you shouldn't do it unless you've a problems with audio, screen and one more.
Is it safe to perform PRAM reset? I mean it wouldn't crash anything or something. Sorry kind of new here

MBP Won't sleep when the screen/lid closes...

I have had my MBP for almost a year now and my AppleCare is about to expire...
Recently when I close the screen the computer will continue to run and operate as if it was never closed and will not sleep. I took it to the Apple store and they did an SMC reset which sorta helped for about 5 hours. Now it goes to sleep but will take almost a minute at times or won't sleep at all. I was told I would have to send my computer out for a couple weeks but I can't do without a computer. Please help me fix this or help me convince Apple to give me a new computer.

Run /Utilities/Console and click 'All Messages' top left then close the lid and try and put it to sleep.
If no dice open the lid and look at the Console messages - in particular look for lines including "sleepimage" and see what it says ?
I suspect there's not enough space left on your hard drive, or it badly fragmented, and the RAM sleep image can't be created or stored properly ...

MacBook doesn't go to sleep when running out of battery

Hi. I'm having really bad luck with MacBooks lately.
First MacBook had a faulty webcam;
Second had a faulty Bluetooth;
...and now I've invested in the most expensive MacBook model available, the black one, and I'm having trouble with the battery. Here is the problem:
The battery shows a warning when it reaches 15% but... when it reaches 0% it won't go to sleep but instead just shuts down and I lose everything I'm doing.
I have an old iBook G4 that doesn't behave like that and even the previous faulty MacBooks would just go to sleep.
Is there something I need to enable?
The machine is fully updated, including the battery update. The battery was fully charged only 4 times and seems to be working perfectly. It looks like an OS issue really.
Suggestions?

I had a similar problem - my macbook was shutting down at 30% or less battery charge, when under battery power...without any low battery warning or going to sleep like it should. It was also not waking up from sleep properly.
applestore diagnosed it as a battery problem. Apple has admitted they are having issues with the macbook batteries. They replaced the battery with a brand new one, and updated me with the battery firmware update released friday on software update. Free of charge, as it is under warranty still. Plus, they have extended warranties on batteries for 2 years instead of one (even if your original warranty has run out!)
So far, so good. No more sudden shutdowns at 30% battery power or less. Battery drains, gives you the normal "low battery" alert, then goes to sleep on its own as expected without powering off. No problems waking up from sleep. Battery time also seems to be noticeably longer.
I recommend anyone with battery shutdown problem (or other battery problems) to visit applestore and get their battery replaced ASAP. Seems to have worked here.
Hope this helps!

Not putting mbp to sleep when closing screen, possible?

Dear All,
I was wondering whether it is possible to close the screen without putting the MacBook Pro to sleep but instead having applications running or listening to music etc. Is it possible to adjust the settings for that? I haven't found anything in System Preferences, yet.
I would appreciate your help,
Jerome

Ya my blue tooth mouse works well for waking it up into clamshell mode, even though that's not what I was shooting for. I just want to turn of the silly mouse...LOL
The problem is with the clamshell, unless you have an external monitor attached you can not visually see anything to restart what ever application stopped when you closed the lid.

How do I prevent computer sleep when on screen saver

Hello,
I have an early 2009 MacBook Pro (17 in.). Since installing Lion, I have a problem when my MBP stays on the screen saver for a while. (Arabesque). I have set my Energy Saver preferences so that when on power adapter, the MBP goes in Display sleep after an hour, but never goes in Computer Sleep.
However, when I leave it like that for a while, the computer still goes to sleep.
Does anybody know what I need to do to make it respect the Energy Saver preferences?
Thanks, Dan.

Yes it's important to have both. Basically, I'm using third party
software, a surveillance program to trigger Insteon and X10 portions of my
home automation. The only way to do this on a motion detection event is to
run an executable from that program, so I'm doing so by launching LV with
the vi as the argument. The problem currently is that when the motion even
occurs, the vi pops up for a split second and then runs in hidden mode.
I
did try the transparant thing, but it still grabs focus away from the current
application. Wouldn't be an issue at all if the pc were dedicated to the
security system, but it's used for other stuff too.
I do have a fallback
and that is to listen to UDP on assigned sockets from the surveillance program.
I would prefer not because it's intended to be used only with the remote
video playback client program and more importantly, if LV isn't running,
then I'm SOL. Currently, the VIs that are launched do to camera activity
also make sure through path and call references that the other parts of the
system running is LV is running or launched if not.

IBook doesn't sleep when I close it.

Well, I almost know the reason. I took my iBook to an Apple Center to have my combo replaced. Since it came back, it doesn't go to sleep when I close it. So, it's obvious for me that the guy over there didn't re-assemble my machine properly.
But before I travel to other city again to have this fixed, I want to try software solutions first. Who knows it was a coincidence.
Thanks for any help.
JP

Thanks John.
I'm really sad hearing that because as long as I understood, the guy there will have to open my iBook again to fix just that.
Sincerely, I didn't like the service from the Apple Center. I don't know which tool he used but, the guy who opened my machine dented the lower case while removing it.
The owner of the store tried to tell me that it is a difficult machine to open, but i don't think it's impossible to do it without causing damages to it.
Well, anyway. I'll think if it's worth it.
Thanks again.

PowerBook G4 not going to sleep when closed???

My 15-inch 1.67 GHz PowerBook doesn't go to sleep when closed. The Apple on the back on the display stays lit and the display doesn't go dark either. Anyone have any ideas???

Check that your sleep magnet hasn't fallen. Take something made of steel like a paperclip, and see if it sticks to the outside of the case above the Apple logo. If not, the magnet inside may have moved. When the cover is closed, the magnet is directly over and affects the trackpad area. If you have a magnet (like on your refrigerator), wave it over the trackpad and it should go to sleep.

Won't go to sleep when I close lid

I recently bought a Powerbook G4 Ti at a flea market with a broken screen that came with the replacement screen. I spent about 4 hours taking the powerbook lid apart and swapping out the screen (PAINFUL!) and after getting it all glued back together, there seems to be some problems with the lid-closed sensor. It doesn't seem to know when the lid is closed or opened because closing it doesn't put it to sleep and if I open it after sleeping and closing, it doesn't wake up. Does anyone know where the lid-closed sensor is on this model?

Hi, Beni_Rose. Sleep is activated by a tiny magnet attached to the back of the LCD panel. When the lid is closed, the magnet normally activates a magnetic switch in or under the trackpad or wrist rest, depending on the PB model. The following instructions pertain to most of the Tibooks: those with processors faster than 500MHz. If your Powerbook is the 400 or 500MHz model, post back for a different magnet location.
Using a small toy magnet or refrigerator magnet, hold it about 1.5 inches above the trackpad surface, over a point that is halfway between the center and the left edge of the trackpad and about an inch from the top edge of the trackpad. Slowly lower the magnet toward the trackpad until the Powerbook goes to sleep. If it does so, you'll know that the switch is functional, and in that case, the likelihood is that you didn't replace the magnet correctly (or at all) when you replaced your screen. Or possibly you used a screen from the 400 or 500MHz models, which have the magnet and switch in a different place. After what you've been through, I doubt that you'll consider it worthwhile to tear things apart again for the sake of getting the PB to sleep when you close it — it will be much simpler just to put it to sleep manually before closing it. The fact that it doesn't wake automatically when you open it is a blessing in disguise: it means the Powerbook can't wake up and cook itself to death inside your carrying case if the latch accidentally releases in there.

My Macbook Air wouldn't go to sleep when I close the lid. I have tried to reset the SMC, but it didn't solve the problem.

Normaly it goes to sleep, when I close the Lid, but suddently this function stopped. That means that Mac'en still is running and become warm, during transport.
(Macbook Air 13 ", medio 2011, 1,7 core i5, 4 MB ram, 256 GB, iMac 22", Timecapsule 1 TB, Airport Express, 2 Iphone 4, 1 iPhone 3s, iPad2)

Test after each of the following steps that you haven’t already tried:
Step 1
 ▹ System Preferences ▹ Print & Scan ▹ Open Print Queue...
Check all printers for unfinished jobs. Deal with any you find.
Step 2
 ▹ 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
 ▹ System Preferences ▹ Energy Saver ▹ Schedule… ▹ Start up or wake: uncheck
Step 4
Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable.
Step 5
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
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 6
Boot in safe mode and log in. The instructions provided by Apple are as follows:
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).
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 Mac OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the Mac 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 7
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 8
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.
