The screen turns off suddenly full black

Hi,
Have a problem with my screen she turns off suddenly full black for nothing.
John

The question is "when does the screen go black"?
Is it black when you are looking at it, or when it's up to your face? If the latter is the case, thats the way it was designed. The proximity sensor turns the screen off so your cheek does not terminate or make other changes during a call. The sensor is located directly above the screen. Make sure the case, if you are using one, does not block it.

The phone turns off suddenly

even when it is still loading, the phone turns off and I can only restart it by plugging it into an outlet to recharge

Have you tried a reset by pressing and holding the sleep/wake button and the home button for 20 seconds (maybe longer) until the Apple logo appears, ignore the red slider. Then turn back on. You won't lose any data doing the reset.

On iOS 6 you can't setting the screen turn off time?

TS3700 why does my music stop playing when i press the sleep/wake buttom? it says the screen turns off but the music should be playing

why does my music stop playing when i press the sleep wake button? it says that the screen should turn off bu the music should still keep playing

This is usually a sign that your headphones are not plugged all the way in. Make sure the white part of the headset is flush with the body of the Nano and no silver from the plug can still be seen.
If you are 100% positive that the earbuds are all the way in, double check to make sure the headphone jack is clean and clear of debris and/or damage.

Is it normal for Macbook to cancel downloads once the screen turns off?

Anything I try to download will download perfecly fine as long as the screen is on. But if something is downloading and I leave my computer for a while, it completely stops downloading as soon as the screen goes into sleep mode. This makes it impossible for me to download anything over night. I tried to re-install Lion last night, but I woke up this morning only to find that it had stopped not long after I had started it. My Macbook was connected to the power cord during this entire process, so I know that isn't the problem. Is this how every Macbook is, or is this not normal?

Click on the Apple in the menu bar, then System Preferences, Hardware, Energy Saver, Power Adapter, and set Computer sleep to Never. Also uncheck the 'Put the hard disk(s) to sleep when possible' and see if that solves your problem. [Go Hoosiers!]
I used to have a dial-up internet provider that would time-out after 30 minutes of no keystrokes, regardless of other download activity.

HT1363 i have an 8GB ipod touch, it's pretty old now. I've recently tried to reset the whole device as it is being given to someone else and it only comes up with the apple logo and then the screen turns off again. none of the above is helping?

I've recently tried reseting the whole Ipod and it came up with an on-screen message saying ''are you sure you want to reset the device? it will take up to an hour and no music or pictures will be restored'' so i clicked ''Yes, Rest'' (or what ever it said). I am now sitting here 24 hours later with an ipod that won't turn on.
i have tried holding the 'power' button down along with the 'home' button for 30 seconds etc.. and nothing is working; it won't show up on Itunes niether the computer. why won't it turn on?

S890 screen turns off while playing games

I bought this phone a week ago.Everything about this phone is awesom except one thing. The screen turns off while playing games automatically,which is really annoying. Is there any fix for this??

Graphics card springs to mind;
also, in your game settings, in either options or video settings (or similar). Are the settings correct for your card. I know on a low end PC, "full hardware acceleration" can cause crashing.
I'd still think, it's more a graphics related problem. If you have a big flat screen mintor (e.g 24,27 or even 30") then that, in it's own right needs a good card. Add the game to it and you may have problems. I do take it you have compared the specs with what's required on the box (of the game) and "about this mac/"more info"). All the best.

Can't type in text when turn phone landscape and screen turns off

When I turn my iphone 6 (regular not plus) sideways to type in text most of the time it won't let me type anything and sometimes the screen turns off. If I reset back to portrait a few times sometimes it will start working and sometimes I have to reboot for it to correct. Anyone alse having this issue?

I am having the same issue. It won;t let me text in landscape - but if I turn back to portrait start typing and turn back to landscape it will allow me to continue. And I am also getting the black screen occasionally as u mentioned

[SOLVED] Screen turns off on boot at "Loading ACPI Modules"

So, I have been using arch for some time and am really liking it so far. It has replaced Windows on my desktop and am planning to install it on my laptop when I get a chance. I showed my parents some audio apps that run under Linux, and they suddenly wanted arch too! I decided to install arch on their desktop, so after migrating Windows to a larger hard drive, I installed arch onto the remaining space... Everything seemed fine until I tried to boot into the new system. Once it reaches "Loading ACPI Modules" the screen turns off and refuses to turn back on. I have tried everything I could think of (booting into the LiveCD again and running pacman -Syu on the new install, swapping the monitor to a different video port, reinstalling arch) and some solutions I found on the forums (adding acpi=off, noapic, nolapic_sound to the boot line.) The latter made the boot skip ACPI, but the the screen blanks on "Waiting for udev events to be processed"! I'm thinking it might be something to do with the video card (an old Radeon X1300 AGP) but I don't know what to do to fix it... The system doesn't lock up, as even after it blanks I can log in and push Ctrl-G to make a terminal beep! I've tried everything I can think of... If this doesn't work I'll probably try another distro on that machine. The system is:
Intel D845WN Motherboard
1GB PC133 RAM
2.2Ghz Celeron Processor
Radeon X1300 AGP card
Sound Blaster Audigy PCI card
USB 2.0 PCI Card
PCI NIC
Thanks in advance for any advice!
EDIT: Actually, I think it does lock up, as I don't have to hold down the power button to turn it off after the screen blanks.
EDIT AGAIN: Thanks, adding "radeon.setmode=0" worked like a charm! I knew that card was a bit wacky, but I didn't think it would stop the system from booting...

ok, seems it's the automatic kernel mode setting (KMS) that causes this see:
http://wiki.archlinux.org/index.php/ATI … _.28KMS.29
to get the system to boot, go into the grub menu, edit the boot option (i.e. press 'e') then edit the line that looks like
kernel /vmlinuz26 root=...
and add
radeon.modeset=0
at the end of it. Then your system should start fine. Now add this to the corresponding line in /boot/grub/menu.lst

Yoga 2 13 Tablet Screen turns off when in Tablet Mode

I just bought my Yoga 2 13, when I flip it to Tablet mode, the screen turns off. Apparently it goes to sleep. When I open it it turns on again. Do I need to do any adjustments? or is this a defect?

Try updating your drivers first: http://mobilesupport.lenovo.com/us/en/products/laptops-and-netbooks/yoga-series/yoga-2-13-notebook-l...
If that does not help, try a factory reset:
1. Turn off your Yoga 2 13
2. Press the tiny button next to the power button on the right
3. Follow instructions to perform a factory reset
If none of the above attempts have helped you, it is probably a hardware issue.

Early 2011 Macbook Pro screen turns off/on

I was listening to music and doing some homework when the screen turned off and then turned back on. The computer wasn't hot at all when it happened. The music also stopped when it happened. After a few seconds it turned back on and everything went back to normal, I had sound and everything. I'm not exactly sure what happened, battery was at 87% so I'm sure it wasn't that. This is the first instance of it happening. If anyone has any advice or knows anything I could do to ensure it doesn't continue or get worse it'd be very much appreciated.

I thought it might have been an update that triggered it, but I guess not. It could be your hardware, but I would try to dianose software reasons first.... such as something else you were running that triggered a resolution change. Whats involved in "doing your homework"?

MacBook Pro (June 2010) freezing with screen turned off (not sleep)

Hi.
This issue has happened to me two times now. I recently bought a Macbook Pro 13 inch and the problem has happened when I let the computer sitting there without moving anything with its lid opened, after like 20 minutes when i'm going to use it again it has the screen turned off, the fan on and the indicator light half way on constantly but anything would respond, to use it again I have to hold down the power botton until it turns off.
It was not sleeping because I have the sleep timer set to never, what I do have on is the sleep display timer to 15 minutes.
Any ideas?
Thanks

Please help!
Now I got this then of turning it back again and a 3 min loading of the OS.
What could it mean, I don't know how to read this please

Screen turns off immediately when setting systemIdleMode to NORMAL after having been in KEEP_AWAKE

I've found a little issue in Android...
In my application I download some files the first time it's run. Since it takes a couple of minutes without user input, the screen turns off automatically. I've found some tablets not only turn off the screen but also interrupt the download altogether when going to sleep, so to avoid this I'm using this to prevent the screen from turning off (is there any other workaround to prevent downloads being interrupted by sleep?):
NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.KEEP_AWAKE;
Of course, I've also added the WAKE_LOCK and DISABLE_KEYWARD permissions to my app descriptor, so the above code works. The problem is that I don't want the app to stay awake all the time, so after the download finishes, I'm setting the screen back to normal with:
NativeApplication.nativeApplication.systemIdleMode = SystemIdleMode.NORMAL;
But after executing that, the screen goes off immediately, instead of waiting for a minute or so before dimming the screen. It's as if the dimming was triggered already during the download process, but didn't actually happen because of the KEEP_AWAKE setting, and then when switching to NORMAL, the screen dimming takes place immediately so it turns off.
Is this an intended behaviour or should I file a bug?
How can I manage to set the systemIdleMode to NORMAL but still have the screen on waiting a bit before going to sleep? Turning off the screen as soon as the download is finished is confusing for the user, who might think the app has frozen when it's really just in sleep mode (and the user has to unlock the screen before going back to the app).
This happens in just about any version of AIR 3.x (and probably below).
Also, it happens in iOS as well, but it's less dramatic because the screen just dims a little (app is still visible) when setting systemIdleMode to NORMAL, instead of turning off completely and locking the screen, which is the behaviour in Android.

What do you mean? That it doesn't happen in iOS 6.0 anymore? What do you mean with "me app lock"? Please, elaborate

IMac Intel Core 2 Duo Screen Turning Off

Hello! I have a 17" iMac Intel Core 2 Duo 2ghz Model # 5,1 and the problem is after turning the machine on, and getting logged in, the screen turns off while the backlight is still on forcing me too shut it down via holding the power button down. I cant plug in an external display because that causes the screen to turn off. Im thinking its the logic board (more specifically the video card) that needs to be replaced. Does anybody know what I can do to fix this? Besides buying a new logic board? Maybe its because its running Snow Leopard and cant handle the OSX?

A good chance, but...
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
