Cinema display turns off
I have a cinema display attached to a 2008 iMac using a power adapter. It used to work fine, but now the cinema display randomly turns off and the only way yo get it on again is to unplug it and plug it back in. What is the problem?
I have a 20" Cinema Display connected to an early 2008 MacPro. After years of service the monitor suddenly started going black, quite randomly. It would even happen part way through playing an edit from FCP. Strangely audio would be maintained though picture was lost. If I switched monitor power off and on again I would usually restore video image. Sometimes I had to do this power cycling repeatedly.
Looking through other posts it seemed a failure of the internal power unit was the most likely cause of the problem. But replacement seemed risky and not guaranteed. I considered buying a new monitor (probably a Dell UltraSharp since the Apple monitors are now so expensive).
Then I tried something else. In System Preferences and then Energy Saver I set the Computer Sleep slider to 25 minutes (I had always previously kept it on 15 minutes). Bingo! Problem solved.
Maybe this won't work for everyone but it certainly saved me some cash outlay. For now.

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.

W520 - now changes to "projector only" whenever display turns off in power save mode
I have my W520 in a dock with an external monitor. The display is configured to Extend - the external monitor is primary, and the desktop extends onto the W520 screen. I don't have a screen saver. I turn off the display after 30 minutes of inactivity. Until recently both the laptop and monitor screens would turn off after 30 minutes, and then both resume when I moved the mouse or pressed a key.
Recently, the system has started changing to "Projector Only" when the display turns off. After resuming from power save mode, only the external monitor activates, and the W520 screen is disabled. I have to use Fn-F6 to switch back to "Extend" to re-activate the laptop screen.
I have rebooted and re-saved the power plan.
Why has this happened, and how do I fix it?Hi, timg11
I have a few questions so that I may gain a better grasp of this issue:
1) What is your machine type and model? You can find this information on the bottom of your machine. It should be in format XXXX-XXX.
2) What is your operating system?
3) Does this issue occur is the computer is not in the docking station? (Please try if you haven't already).
Thanks in advance,
Adam

White Stripes/Display Turning Off
Last night I noticed a bunch of white stripes flicker for about a quarter of a second on my display. This happened multiple times. I shut it down with no problems.
Today I had no problems until everything froze. I could move the mouse, but it would not change from a text cursor. I manually shut it down.
I turned it back on, after a few minutes I had the same issue.
I turned it off manually, unplugged the power for about a minute, plugged it back in and turned it on. After a few minutes the white stripes flickered. I decided to back up everything. After about 10 minutes, during the backup process, the screen went black. I could feel that the computer was still on, but the display was black. I manually turned it off.
I have now been on for about 30 minutes with no problems. The computer was very hot when the display went black. Is it possible that this is an overheating problem?
Any suggestions?The iBook has a seperate display dimming (display turns off) and sleep mode timers. Go into the system preferences>energy saver to set these preferences. When your display turns off you should be able to reawaken it by pressing a key on the keyboard. Turning it off is not the best solution. If the problem happens while you are still using it or it doesn't awaken when you hit a key then you may need to post here again.

L305D-S5935 Unresponsive After Display Turns Off
I have a L305D-S5935 running Windows Vista and it becomes unresponsive after the display turns off as set to do so in the power settings. I cannot push any key or button or move around on the mouse pad to get it to turn back on. This is very frustrating and the only way to get it to come back on is to to a hard restart.
Turn off your laptop, unplug all wires, remove the battery, and hold the power button for thirty seconds. Afterwards, reattach the battery and connections.
Then reinstall TVAP.

My ipod stills pauses when the display turns off, even though, my headphones are correctly attached (or flushed)
Does this happen still when you use another set of headphones? Have you check to make sure the headphone jack is clean and clear of debris? If so, the jack may be faulty or damaged meaning you'll need to take or send your iPod in for service/repair.

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.

Macbook pro 15" and 17" display turns off whilst working then.......
I have 2 macbook pros. One 17" and the other 15" both are the non unibody ones. The 15" had this problem a while ago but my 17" never did it until today and then it did about 5 mins ago.
Whilst I am working (never seems to happen when I am not using it) the display turns off whilst working. The power light remains constant (ie:- not fading in and out when asleep). But here is the strangest thing. The mac repetitively makes the same noise as if it was ejecting a disk. Has anybody else had this? Know a cure? I recently upgraded to snow leopard but don't think this is a software issue.I got the same problem with mine, 15". I bought it refurbished from apple store. I had this problem when i bought it then nothing happened for 4 months. But now my MBP has started doing it again. And i don't think it's a software issue. My display switch on after few sec, or 1-2 mins it's depends, and it's pretty random. i'm a bit of worry

Hello everyone,
I don't understand why my Mac display turns of automatically when another electronic device is brought near it. The system is still running but the display just goes black and Mac logs the user out. The other day I got off the phone while working and I put the phone on the left side of the Mac just above the speakers and display went black. I pressed the keys but in vain. I removed the phone and put it back in the dock. The display comes back to life with me logged out.
The happened many times after it and before the incident but the thing I observed it, the display turns off when an electronic device is brought near it. The weird thing, it turned off when I put the Mag Safe pin on the speaker noticing that the power is full. Is it due to some kind of interference of the Mag Safe's(other devices) magnetic field with Mac's power ciruits? I also noticed that this happens only when the device in context is on or plugged in. I just want to make sure that thats the reason or my Mac has some problem!!You should call Apple service number they will surely help you. You should find it in your computer's documentation. Good luck!

Macbook display turns off when booting Snow Leopard DVD
I have mid-2009 Macbook Pro and I hate Mountain Lion. I want to do a clean install of Leopard using the DVD (grey) that came with my computer. I loaned it to a friend recently and he had no issues. But everytime i try to boot from the SL DVD (hold C at startup) it behaves normally, until about the time it would go into the DVD startup screen. At that point the display turns off (not the whole computer, just the display) as if it has gone to sleep. And I can't get it to turn on again. I've also tried booting and holding Option and choosing the DVD as the boot drive. No dice.
Awhile back I created a Lion install DVD. I can boot to it just fine. But i don't want Lion either. Any ideas why this is happening? Thanks!Press control shift eject, then any key to toggle the display from sleep/wake.

T42 Display turns off after moving
Hello everybody!
I´ve got a problem with my Thinkpad T42 (2373fwg), XP prof. with the latest updates running. After installing the latest drivers for display (ati) and for "ThinkVantage Active Protection System " the display turns off immediately after moving the Thinkpad. I can turn the display on again only by reboot. The error appears even in a second after reboot, so it doesn´t concern to windows. The system doesn´t crash, it´s only the display. The problem might concern to the shock sensor, but I don´t know how to solve it.
Does anyone of you has an idea?
Thank you and kind regards
Bill
Message Edited by billyflinn on 01-26-2009 09:29 AMI have a similar problem: T42 (2373-5wg) Screen blanks. At first screen blanking was rare and seemed to happen when moving the pc, but now the screen blanks within 1-3 minutes after turning on the laptop, even if the computer is left untouched after being turned on.
It is not OS related as the blanking appears even when in BIOS setup or booted on a liveOS CD.
I can't tell for sure if the system crashes or not as the display goes blank (doh!), however, I have seen no reports of registered crashes in the visible part of the boot process.
The screen blanking appears quicker (or even instantly) if the computer is warm (e.g. turned off just before being turned on).
Blanking appears simultaneously on the LCD and on any attached external monitor, so I believe this rules out a defective LCD, backlight or inverter board.
I'm thinking it's a failing graphics adapter or system board, or maybe a loose connection that causes a component to overheat and fail. But I don't know which or how to fix it.
It IS out of warranty, of course. Any ideas?
Thanks in advance,
Niels
EDIT: It seems this could be yet another case of badly soldered BGA chips that seems to be troubling the T4x series:

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!
