Thunderbolt Display Turns Off/MBP Goes to Sleep in Clamshell when MagSafe unplugged

My battery is fine, but I can't use my 2011 15" 2.2ghz MBP + Thunderbolt Display in clam shell mode without being plugged into power from MagSafe. Disconnect the cable, Thunderbolt quits and MBP goes to sleep.
This drains battery by being constantly plugged in.
I updated my the TB firmware today when prompted. Problem existed before and after.
Let me know what's up, very annoying.

The internal battery could handle the extra power needed when using the external display, but OS X (or maybe the firmware) doesn't allow clamshell mode without external power.

If it did, the extra discharging and charging would mean replacing the battery sooner.

Thunderbolt Display turns off randomly

I have a new Mac Mini 2011 i7 Quad CPU version. I have a Thunderbolt 27 inch display. I have found that the display randomly turns off and won't turn on when I use the keyboard or mouse. This occurs when I am doing stuff on the machine, it is not a display sleep issue. The first couple of times I had to use Remote Desktop to reboot the Mac Mini to fix the issue. The last time it happened I removed the Thunderbolt plug from the Mac Mini and reinstalled it and this fixed the issue. I have the latest software updates on the Mac Mini and the Thunderbolt Firmware update on the Display.
I am running Lion 10.7.1

Well, i've just patched firmware update for Thunderbolt display from Apple customer support site. I'm sure you've done this already because it's dated 19, Sep. Well, I'll try to find the pattern anyway if the same thing happens again.
And, for your information, those happened while i was using 'Remote Desktop Connection' from MS-Office, which i set as expanded 'full screen', targeted Thun-di, (I've mentioned i'm using dual display, Dell 2311H and Thun-di above reply).
Plus, I found some interesting bug for the 'full screen feature' of RDC of MS-Office, which is sometimes got confusing which 'desktop' it should use. when i added one more desktop from 'Mission Control', ran RDC in full screen mode from 'desktop 2', it should just remained on 'desktop 2' when i switched to my original 'desktop 1'. But, when i did switch to 'desktop 1', RDC just switched to 'desktop 1' and remained in 'full screen mode'. I feel strange, 'cause the feature worked fine yesterday, but not today, and the 'Thun-di''s gone randomly.
Too many clues and multiple bugs appeared at the same time, made me confused, RDC of MS-Office, Lion, and Thun-di(oh, just added patch from Apple, TT)...
Wait for solution with fingers get crossed, haha...

Is there any way to log off automatically from a WIFI connection every time the device is turned off or goes into sleep mode.

I have a bunch of Apple devices in my house (kids) and don't like the idea of all these devices (iPads, iPod touches, iPhones) always being connected to my home WIFI. Ideally, I would prefer the devices connect automatically when they are in use by a human and log off the network when they (the devices) go to sleep mode or are turned off.

This is not an answer, more of a question. I know that when a pad goes to sleep, it drops the connection. We all remember the thousands of posts from folks who had trouble re establishing the connection after waking up in the early days. What is different now is the use of push, and notifications. If you have these enabled, doesn't that mean that the wifi needs to stay active?
I notice that I have notifications on the screen that came in while asleep, and I can only believe that the wifi saw them. This is different from the old behavior or re grabbing the wifi.
So, to Pam, on one the devices you are concerned about, turn off notifications, fetch and push, put it to sleep, and see if it drops off the network. I am kind of curious.
By the way, having the wifi active has not shown me any battery usage. The router certainly does not care. Security is at the router end, so if somebody wants to hijack my signal, it does not matter if the pad is active or not. So I guess I am not clear either on what your issue might be.

Thunderbolt Display turns off / flicker / very warm

My Thunderbolt Display 27 is connected to my MacBook Pro Late 2013. After a while it turns off, starting to flicker. Disconnecting from MacBook and reconnecting the Display works for a while again. Same problem I have with my older MacBook Pro. So I am sure its not a problem of my latest MacBook Pro.
I have tried to turn of power saving, automatically brightness adjustment, doesn't work.
The left backside of the Thunderbolt is really very warm. Maybe its a fan problem ? The Display is only two years old and I was expecting to use it at least for 6 years.
Current firmware for thunderbolt display is installed.
Is there any solution for that ?

Did you purchsase Apple Care for the TB Display?

Imac makes fan noise when it turns off or goes to sleep

Hello,
I bought a new iMac from bestbuy during the last week of april 2013.
Recently when I turn the iMac off or put it to sleep, it begins to make a loud fan noise at the back above the place where the power goes into the iMac. However, the moment I turn on the computer the sound goes away.
I left the iMac on for a few hours thinking the noise will go away on its own but it didnt. Now I always have to turn off the iMac and take the power out of the wall in order for it to not make noise.
Does anyone know what I can do to solve my problem? I have tried the SMC reset and the Pram reset however it does not seem to do the trick for me.

I would recommend resetting the SMC at least 3x back to back, sometimes it does not work the first time. If you don't know how please navigate to https://discussions.apple.com/docs/DOC-3603 for detailed instructions. If that does not help, you have 90 days of free AppleCare telephone coverage or if you already bought AppleCare (VERY STONGLY RECOMMENDED) this will extend your 1 year warranty to 3 years and includes 3 years of phone support. If you are in the USA you can buy it from B&H Photo for as little as $122 vs. at BBY or Apple for $169.

Turning off or going to sleep?

how do i know if my ipod is just sleeping or if its off..i turn it off how they say and put it on hold...then it turns on with one touch when i take hold off..i think its just sleeping...am i doing something wrong?

No, your iPod is behaving as it should.
http://docs.info.apple.com/article.html?artnum=60945

Whenever my iPod is turned off or goes into sleep mode, it hard boots everytime I turn it back on. This seems to have started only when I upgraded to OS6.

My iPod hard boots everytime I turn it on. I get the Apple logo and 5 minutes later it starts up. This seems to have started when I upgraded to OS6.

Try:
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store.

Cannot turn off MBP monitor/display

I have a 15inch MBP running Boot Camp and XP. I am trying to use the "turn off monitor" setting in power options from the contol panel. However when the time is up it does not turn off the monitor...
Also when the "turn off monitor" feature is suppose to trigger, it disables my screensaver.
I don't want my computer to sleep, I just want to turn the monitor off. Right now I just dim the screen until it fades a little but I can still see my desktop screen so I know it is on.
Can anyone tell me how I can turn off the monitor?

Support are now quoting Apple's engineers as saying it is now "expected behaviour" under Lion for the MBP's internal display to reactivate upon opening the lid, even if you want to use only your external display. A new version of the clamshell mode-related knowledgebase article (replacing HT3131) is due shortly confirming this.
This is despite:
- the obvious temperature-related benefits that were achievable (under Snow Leopard) by opening your MBP lid whilst continuing to output solely to, say, a 27" cinema display
- the waste of energy and inefficient use of graphics processing power in needlessly running two active screens (ie if running your MBP in clamshell mode would otherwise make it too hot and/or noisy)
- the negative longer-term impact on the battery and other components from running the MBP any hotter than it needs to be.
If you would like to have the previous behaviour restored, please lobby Apple to change how Lion handles clamshell mode. Options available to them include changing Lion's expected behaviour or adding a user-selectable option within System Preferences.

Windows 8.1 Screen Locking at Display Turn Off (instead of only at Sleep)

Hi All,
I am having this issue with clients running Windows 8.1 Enterprise, which we are planning to deploy later on this summer.
We currently have a GPO setup for managing the power settings on our staff computers:
This GPO sets computers to sleep after 1 hour, but turn off the monitor after 5 minutes of inactivity
On our Windows 7 systems, the policy applies correctly and if our staff uses their computer before 60 minutes of inactvity (before they go to sleep),
the screens will just turn back on without prompting for login.
I have noticed however on our Windows 8.1 test computers, in the same OU, which receive this policy, that after 5 minutes when the screen goes off, if a staff member attempts to use their computer they will be prompted for a password even though the
unit was not in sleep mode.
Further more, I've noticed that on the Windows 8.1 Systems, I am able to override the "Require a Password on Wakeup" setting using the metro interface, as pictured below (the setting does change in power options as seen below), and does stay in
the No setting even if I run gupdate and reboot.
Any idea how to keep the Require Password for waking up, but not just for computer with the screen powered down?
(I should also not screen savers are not being used)

Hi,
You can tried also set the item Sleep: After 60 min to see what's going on.
On my laptop, once I configure this, the display turns off without lock the computer.

I just added two external firewire drives and they keep going to sleep. I did not have this problem when USB. I have turned off "put disks to sleep" in power preference.

I just added two external firewire drives and they keep going to sleep. I did not have this problem when using USB external drives. I have turned off "put disks to sleep" in power preference.

It is not clear if these are the same drives, just connected
differently, or different drives?
One thing that may be happening is that the drives firmware
itself is putting it to sleep when inactive. Many drives on
the market have ths feature and it is turned on by default
and require a drive utility from the manufacturer to disable it.

My iPad doesn't seem to charge when plugged in to my MacBook Pro if the MBP goes to sleep. My iPhone continues to charge even if the MBP is closed. Is that normal?

My iPad (3rd Gen) seems to stop charging if it is plugged into my MBP if either the iPad is closed or if the MBP goes to sleep. My iPhone charges whether the MBP is awake or asleep or even if the MBP is closed. There is a screen display that shows the iPhone is charging. The iPad only has the tiny icon at the top of the screen that show it is charging. However, the battery's % charged does not increase if the lid is closed when I am charging the iPad if the lid is closed on the iPad or if the iPad off after pressing the on off button. Is this normal?

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html

External display turns off when macbook isn't charging...

I have my old 2007 white Macbook hooked up to an external display. Recently I have been wanting to calibrate the battery while using it on the external display, but every time I remove the charger from the Macbook the external display will stay on for a couple of seconds then turn off, it will only come back on when I click the mouse or press something on the keyboard, but then it will go back to sleep. Note: when my Macbook is connected to the external display I keep the screen closed.

When you are looking at the displays in the System Prefs, all you have to do is click and drag the tiny rectangular bar from the main screen to the external monitor screen (this designates the primary monitor).
Once you've done that, all you have to do is close the lid. Your screen will flash a couple times, but the external monitor will then remain on and working, and you dont need to keep your lid open.
FYI, I would turn down the brightness of your MBP down all the way (for both the screen and keyboard). I have found that this reduces any heat build up that it may have from running with a closed lid.
Hope this helps!

IMac display turns off automatically.

Hi everyone!
I have a problem with my iMac. The display automatically turns off while using the computer and I can't continue using it without forcing it going to sleep. The display turns off when the screen brightness is NOT at maximum level. If I reduce the brightness, the screen turns off. If the display it's at the maximum level, no problem, works perfect. No matter if the computer is just turned on from a cold start or if it's running since hours with high temperatures. In System Preferences there's only one option selected in the Enegy Saver section (Allow power button to sleep the computer).
Any ideas? It's really annoying working with this problem (especially at night with the brightness at maximum).
Hope somebody can help me!
(Sorry for my english).

Display Turns Off After Opening Computer

I have a very annoying problem of my display turning off and not turning on until I restart my Macbook Pro by holding down the power button.
For example, I will close my computer (power cord not plugged in) and it will go to sleep. If for some reason the computer turns on while it is still closed (this happens when I pick it up/move it around sometimes) and I then open the computer, the display will be on momentarily and then turn off leaving me with a black screen. The only way to turn the display on again is to restart my computer.
Another example: I might close the computer with the power cord in. I will then unplug the computer (still closed) and walk somewhere, then open the computer. The display will be on for a few seconds and then turn off, leaving me again to restart my computer.
The third example is the worst. Sometimes with the power cord still in, sometimes with no power cord, the display will just be blank when I open the computer.
With all of the above occurrences, I know the computer is running because I can see the caps lock key light change when I press it.
Does this make any sense? Please help me, I will be going to college on Tuesday and I would really like to have it so I don't have to restart my computer every time before class.
My display was not always this way, it has just been like this for a few months.

Im surfing this kinda of problemes. Its insteresting your computer turn on the screen after restart, but there no much good news for us in here: http://discussions.apple.com/thread.jspa?threadID=1478474&tstart=0

Yoga display turns off after 1 minute

I'm having an annoying problem with my new Yoga related to the display and have not seen any other posts with a similar complaint so perhaps this is a simple fix that I'm just not able to sort out on my own. My display turns off after 1 minute of inactivity. The only means for changing behavior like this that I am aware of is through the Control Panel Power Options. My settings for "turn off the display" are 10 minutes on battery and Never while plugged in (note screen shot attached). Regardless of my settings, the screen turns off after 1 minute. I've changed the settings to multiple configurations and restarted with no change in behavior. Perhaps there's some other settings area, maybe something specific to Lenovo that I'm not aware of (since this is my first Lenovo laptop). Anyone with similar problems or insight?

This may be a Windows 8 issue. I finally fixed this problem by identifying the screen saver as the issue (and I wasn't using a screen saver). Type "lock the computer" into the search box after clicking the search charm, which brings up the screen saver dialog box. Mine was set to 1 minute, though I'd never set it myself. If you can't change it, choose a screen saver and you should be able to do so (and can then switch back to no screen saver). BUT, here's the problem. Other things you install (or settings within things you install) can apparently change and override whatever you type in for the delay time. Try applying your new time and exiting from the dialog box, then open it back up again. I was finding that it kept going back to 1 minute. To reset things so that you can get control again, type "user accounts" into the search box and when the dialog box comes up, choose "Reset Security Policies". Then you can go back to the screen saver dialog and successfully change the delay time.
