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.

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.

IBook will not sleep when lid closed

Hi,
I recently had my Hard Drive replaced, the old one died. It was all covered by AppleCare and the repairs done at a Apple Authorised Outlet. After installing everything again I just found out that my iBook will not sleep when the lid is closed. The screen is still on and bright. Any ideas why? Is this dangerous? Any quick fixes?
Cheers,
Jack

Jack,
Welcome to Apple Discussions.
You need to give the Apple Authorized Repair center a call back and let them know what's going on. I've seen this before here on the forums, and it was attributed to a sleep magnet not being put back in. It's most likely this. Apparently, putting this magnet back in can be easily overlooked.

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!

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.

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.

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.

I opened a PDFs file that was attached to an email message and now it will not close when I press "Done" as it usually does. Does anyone have a solution to suggest? Thanks.

Macbook Pro 13" will not sleep when I shut the lid

Hello Community,
This is my first time using the forum. I have a macbook pro 13" 2009 model. Recently I had my MBP connected to an external monitor. I shut the lid while it was connected to the monitor and forgot to turn off my bluetooth mouse. Later that night the mouse was bumped, waking my macbook and setting it to clamshell mode. I put it to sleep again, opened the lid and woke it, but the LCD on the laptop did not turn on. I reset the PRAM and the NVRAM with no luck. I disconnected the monitor, rested the P/NVRAM and it would boot with the laptop screen and once everything was loaded my screen went black and then went to sleep on its own. I tried powering on and off using the P/NVRAM key commands...and nothing. So I opened the bottom case and physically disconnect the battery, reconnected the battery, put the bottom plate back on and powered it up. The screen began working again, now I have a new problem, the MBP WILL NOT sleep when I shut the lid anymore. I even reinstalled the OS and still no luck? If anyone has anything helpful that I could try to get this feature working again it would be much appreciated. If there is some terminal command I could try or some other troubleshooting method. I even put a magnet by the right side of the keyboard to try to trigger the sleep switch.
Any advice would be appreciated.

I resolved my issue in a very unlikely way. In my earlier post I mentioned that I wiped my hard drive and was starting from scratch. Well I reinstalled windows 7 through bootcamp and it fixed my sleep issue. That's right folks...Windows fixed my mac. I think that it was an EFI issue. I think this because windows 7 uses EFI and during installation it must have reset the sleep values to normal. I feel when you reinstall Mac OSX the EFI partition on the drive should get wiped and reinstalled as well. I also feel that apple should have an option within System Prefs for the user to select what the way is that the computer responds when the lid is shut instead of the ritual of trickery and problems that the clamshell mode can cause.
Hope this helps someone.

My iMac will not sleep when not in use.

The screen will go dark, but the disk will not sleep when not being used. I have restored defaults and set energy settings to do so and still no luck. Any thoughts? Was this part of a current update? It just started to not sleep a few weeks ago.

Thanks for your help regarding my computers sleep disorder. I wanted you to know that after many hours of searching, I found that I had downloaded a program called Growl with my Belkin router when I installed it. I removed this Growl program and finally my computer will sleep on it's own. I wanted to give you this info just in case you come across this problem again.
Thanks again!

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

X120e does not sleep when lid closed

I found another similar post, however it was resolved by the individual reinstalling the operating system.
My issue is more complicated. I have made sure everything is up to date, all the settings that tell the system to sleep when the lid is closed are turned on. I have even turned those settings off off, just so I could turn them back on to make sure there wasn't something quirky about it.
I have tried restoring the system to factory settings using the recovery partition, as well as discs burned from the program that came with the computer. I have tried clean install from Windows 7, 8, and 8.1 discs.
The unit still does not sleep. I don't ever remembering it being able to. I once closed the display thinking it would sleep (power was plugged in). Woke up the next day, went to work for 8 hours, came back and felt that the system was really hot. Opened the lid and the screen was exactly as I had left it the day before.
When I first got the system in 2012, the screen did not work, so I actually had to send it to Atlanta, GA for repairs. It came back quickly, and it still did not work, so I actually sent it back to Atlanta, GA's repair center a second time in the same week. It came back working and I left it alone. I never tested the sleep/wake because I always just turned the system off when I was done with it, but now I am back in school and this little computer comes in handy, but I don't want to turn off the system manually going from class to class when I need to pack it away in my bag.
Could there be a hardware issue? Something inside not connected? This laptop works perfectly EXCEPT for the fact that it will not sleep when the lid is closed. It is out of warranty but had I known this was an issue while it was still under warranty, I would have inquired. This unit is in pretty fantastic shape, looks brand new too. No damage, never been dropped, and only ever handled by me (never loaned out).
How can I fix this?

Thanks for the reply, gat0gelat0.
Yes, those settings were the first things I checked. I also tried changing it to "Do nothing", then changing back to the sleeping option. It still does nothing when I close the lid.
I would like the functionality of it going to sleep when I close the lid for the convenience, like when class ends, I have to rush to my next class, I just want to close the lid, put it in my bag and run to the next class. Keyboard shortcuts like Fn-F4 work, but this laptop should have the functionality I am describing, and I want to figure out why it isn't working and how to fix it.
I suspect there is an issue with whatever is used hardware wise to sleep the machine. Either it's not being triggered, or it's not there, or it's broken. I've tried running a magnet around the bezel of the LCD screen as well as around the palm rest bezel and there is no activity as I've read that many laptops trigger sleep by interaction by a magnet. Still nothing.

MacBook Pro will not sleep with lid open, but now solved, very odd.

I bought a 2.4 GHz MBP about a week ago, as soon as I got it home I reinstalled the OS and zero-out the drive. Everything appears to work perfect until I noticed that the MBP will not sleep with the lid open.
But...
Close the lid, it sleeps.
Select sleep from menu, it sleeps.
Let the battery drain down with lid open, laptop sleeps.
Whent thru painful troubleshooting process, reseting things, permissions, what is installed, running programs...blah blah blah, nothing no difference.
So, backup the drive using superduper to external firewire and reinstall all over again, just like i did when i first got home, except I did not let it connect to the internet. I went thru and setup everything then connected and performed each update, one at a time looking for what might hinder the sleep process.
And the result is a big fat zero.
Same install process as i did the first time, and same updates as the first time. But now the laptop sleeps perfectly.
Gotta love computers, so very consistant
Just my .02 input on this wacky issue.

Try trashing these 3 .plist preferences and reboot. Reset your Energy Saver preferences.
HD > Library > Preferences > SystemConfiguration > com.apple.AutoWake.plist & com.apple.PowerManagement.plist
User > Library > Preferences > com.apple.systemuiserver.plist
Also, look at your system logs in your Console application and see what is causing the "wake event." It could be hardware-related. Do you have any external devices attached, such as a mouse or hub? I've seen Bluetooth problems with wireless BT mice.
