Screen Does not Lock when Lid is Closed

Occasionally when closing the lid and waking up later, the screen is not locked. The Console log shows the following error message:
loginwindow[66]: ERROR | -[LWBuiltInScreenLockAuthLion closeAuthAndReset:] | Attempted to remove an observer when not observing

Any solutions?
Having the same problem. Wondering where the Internet sh*t storm is with a security problem of this size...

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.

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.

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!

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.

MBB Does Not Sleep When Lid Shut

My macbook does not sleep when I shut the lid. This happened recently after I had my fan repaired. I also updated the OS at the same time, so I'm not sure which triggered the problem.
I would have to manually select sleep before shutting the lid; and I would have to press the space bar after I've opened the lid to wake it.
The following thread applies to a MBP. Apparently my problem might be a faulty latch.
http://discussions.apple.com/thread.jspa?messageID=5325605&tstart=0
I've reseted my PRAM, but that didn't work. My machine has been in for repairs 4 times (Fan, Logic Board, and the top case has been replaced twice due to cracks).
I'm wondering if I should send it back to the service centre to have it looked at. Apparently, if this is not a hardware problem, it won't be covered under AppleCare, and I would be charge. So just want to make sure...

I tried doing this fix using the guide on http://ifixit.com to dismantle my MacBook and find the battery/lid detector cable which indeed seemed loose at its connector just next to the headphone jack, but when I reassembled the mac still does not detect lid closing and now it doesn't even detect the battery anymore! Yikes! Looks like a trip to the apple store is required anyway.

My iphone 5s screen does not lock whilst a call is in progress

My iphone 5s has probs whilst calling the screen doesnt lock
Is this proximity sensor or a setting?

The iPhone screen shouldn't necessarily lock while you are in the phone call, it should however go to sleep while you have it up against your ear. Is that what you mean?
If this is what you mean and you think that there is an issue with the proximity sensor I would recommend playing a voicemail on your phone and instead of holding it up to your ear, putting your finger over the upper speaker. If the screen does not darken then there could very well be something wrong with it.
Make sure first however that the area is cleaned and uncovered, just to be sure.

JAX-RPC screen does not appear when generating a WS proxy

I'm using JDev 11.1.1.2. When I tried to generate a Web Service proxy, this screen does NOT appear most of the time. I only saw it appear one time. Do you know why?
It's step 2 of the wizard.
Client Style
+ JAX-RPC Web Logic Style
+ JAX-WS Style

Whenever one tries to generate web service proxies for the first time, JDeveloper allows the user to choose the client style (JAX-RPC Web Logic Style OR JAX-WS Style).
Once the option is selected, JDeveloper automatically adds the dependent jars in the classpath. When one tries to generate the proxies a second time,
JDeveloper does not provide an option to select the client type. It defaults to the one which was selected for the first time.
I was able to overcome the problem using the following approach.
1. For JAX-RPC client style:
Right Click the Model (or ViewController) project -> Project Properties -> Libraries and Classpath ->
Add Library -> select JAX-RPC Web Logic Client, JAX-RPC 11 Web Services
Remove JAX-WS Web Services library (if present)
2. For JAX-WS client style:
Right Click the Model (or ViewController) project -> Project Properties -> Libraries and Classpath ->
Add Library -> JAX-WS Web Services
Remove JAX-RPC related libraries (if present)
I am using Jdeveloper Version 11.1.1.4.0

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.

Log-In Screen Does Not Appear When Resuming From Standby/Sleep

We are running T400s with XP SP3. From time to time when the computer comes out of standby the login screen will not appear. You just get the background image and your mouse. The mouse will move across the screen. However there is no screen saying press Ctrl+Alt+Del or swipe a finger to login. Also swiping a finger, or pressing ctr+alt+del, typing in your password and hitting Enter does not work either. It seems to be a random but frequent occurence. The couple of T400s with Vista installed do not have this problem. Any ideas?

After doing some troubleshooting I narrowed it down to the FingerPrint reader software. Sure enough after uninstalling it fixed the issue but then the finger print reader is useless. I looked at the latest Version, 3.2.0.116, readme file and it states:
<3.2.0.116>
- (Fix) Fingerprint Reader is not working ater 1 minute idle.
- (Fix) Fingerprint Reader is not working after standby/resume.
I am wondering if they are still working out the bugs, nothice the "l" missing from later. Any help would be a big plus as I need to roll out about 200 or so for my employer in the next month.

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.

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.
Joel

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.
