S210 screen blacks out when AC adapter removed

New problem with my S210.
When i have it connected to AC, works as normal.
when AC adapter removed, the screen alone loses power. (computer does not turn off or go to sleep).
simply re-inserting ac adapter re-powers the screen immediately.
this issue does not allow for me to work without ac adapter.
any ideas if there is a setting that needs to be changed, or if this points to a hardware issue would be appreciated.
(no modifications done to this laptop, its running windows 8.1)
thanks

Screens black out when starting program

I don't know where to ask this since it is more related to CS4 in general. I mostly use InDesign, but the two moderators on that forum are trolls. I hope it's better here.
All screens black out for few seconds while starting or closing the following in Adobe CS4:
InDesign, Fireworks, Bridge, Device Central, Media Encoder
This does npot happen with other programs I've found or other programs in the CS4 suite.
Don’t know if this is a software issue or a graphics issue. Everything still works, but it's very annoying.
System
i7 processor
Win7 64 bit
Quadro NVS 450 graphics card
Three NEC EA190M monitors
8Gb memory

Black screens are a well known Windows 7 problem.

Second screen blacked out when full screen with dual displays

I have a MacBook Pro connected to an LCD display. I use both screens. When working from home I'd like to have my local machine showing on the LCD monitor and my work machine showing in the MBP screen. I can do this, however I can't have the work machine in full screen mode because ARD blacks out my main LCD monitor. This frankly drives me nuts as there doesn't appear to be a preference within ARD to change this.
iTunes does the same thing. If I want to watch a video full screen in one monitor it blacks out the other. C'mon Apple, Quicktime doesn't do this and has a preferences tab just for display settings!
Does someone have a suggestion, work around, or want to point me to what I might be missing to solve this issue?

I understand what you are doing, but when you are running as full-screen the second display is blacked out because your making your station only the target at that moment. You are telling ARD that you want nothing to do with your Admin station. Also because the target doesn't have a second screen, your is blank. This avoids any confusion as to what screen belongs to what machine. ARD is working as it was designed to.
iTunes does the same thing to hid extra screens that are not part of the presentation so they don't detract from the show.
With your Observe or Control in Windowed mode, make the window of you client to fill the display as much as possible. This is the best you can do. Besides, when you are Controlling a client in Full-Screen, you can't move files and such with drag-n-drop. So if you want to work on both at the same time, you need to stay in windowed mode.

S200 screen blacks out when lid opened; lid closed it turns on!

This is badder than bad for a problem. When I open the netbook lid, the screen blanks out. This even happens at the boot stage immediately after pressing power button, so that the BIOS screen goes black when I open the lid. On closing the lid though, hey, the screen turns on. If it manages to boot the OS and I open the lid, the screen will black out. Then I close it and it turns on, but often opening it again and the netbook sleeps. A while ago, after that stage of the netbook sleeping, I could open the lid, hit Enter and get it to wake up and then I had roughly 1.5 min to do some work - perhaps longer I didn't actually time it. Now, however, it blacks out again after wake up (and its very hard to shut it down using a pencil reaching the power button!) I've opened the back off the netbook and try to find the lid switch, but I'm still not sure where it is - so that I could disable it completely. I'd prefer not to take it to the service center as warranty is over and I already had a $50 repair with Lenovo, so doing it once more is not really worth it. OS is Linux Ubuntu - and in all the Power settings I set it to do nothing when lid is closed. Any help would be appreciated!

Well, I had the idea of using a magnet to find out if the S200 uses a magnetic lid switch.
I ran it around the edges of lid and outside of keyboard and front... and suddenly, just by the Backspace key it was, the screen came back to life!
As i had the case opened I looked at what part was inside just there, and its the small usb/card-reader board. I couldn't tell if there was a lid switch component there though - but after I touched a few parts there, now the screen is always on when i start the netbook.
my other problem now though is that half of the keys don't work - no output on screen.
so that's another issue!

Screen Blacks Out When Composing Email

When I am composing emails after a minute or two the screen goes black, and the phone reverts back to the home page. The pending email disappears (not even saved as a draft) anyone have a clue how to fix this?

I'll be honest. These are WAGs. However...
Since the Reset didn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

Ver 10.0.1. Entire screen blacks out for a few seconds when scrolling.

I recently updated to Reader X 10.0.1. Now when I scroll through a large document my entire screen blacks out for a few seconds. So far it has recovered. I get an error message saying that the NVidia nView driver (ver. 135.50) has stopped responding. I am running Windows 7 Pro on an HP Laptop, feeding to a large Samsung monitor. Never happened prior to this update. Any fixes/ideas?

Black out when screen is moved

My screen blacks out at times when I move the screen tipping forward and back. There is only a few positions where it will stay on. It's a 2008 black macbook running 10.7.5 and 10.6.8 Everything else is fine. Hardware test shows no problems. Any idea what kind of a repair this would be.
Thanks for any repley
Paul

The symptom is classic of a broken inverter cable. The cable routes through the left hinge to the screen and wears out from opening and closing the screen. It's a difficult repair but following the guide at iFixIt if you have the courage and patience you can do it yourself https://www.ifixit.com/Guide/MacBook+Core+2+Duo+Inverter+Cable+Replacement/4772

Random laptop screen Black out / Turn off .

Hi,
first of all my laptop is : HP Pavilion dv6-6160se Entertainment Notebook
to the problem now
A few days ago my laptops screen started out of a sudden shutting down/turning black( no lights at all ). This was happening while using the laptop at random. The screen had no lights, and if i use a flashlight on it there is nothing. like its turned off completelly.
Before this happens. Ths behavior varies. Sometimes it flickers from my desktop to a black screen then back on and some times not. Most of the times screen changed to a radom color (green mostly) then becomes black/shuts down.
NOTE: The laptop keeps runing, i can hear the videos playing so it probably isnt a gpu chip or gpu issue , music and games.
I searched the web for all kind of reasons that this could happen and tried some of the fixes .
Here are everything i tried and all or the details i could accumulate in past coupe of days:
1. If the screen flickers , blacks out and then turns back on i get a message that gpu drivers have stopped working and recovered ( on both amd and intel ).
2. If the screen blacks out, on rare ocasions if you close the laptop lid and let the laptop go to sleep , when waking up screen works again ( noticable due to screen moving)
3. I tried installing 4 different drivers all with clear install. ( didn't work)
4. I tried to to recover system with restore point. ( didn't work)
5. I tried to lower the screen brightness. ( didn't work)
6. tried this trick:
Turn off laptop
Remove battery
Hold the power buttong for 30-45 seconds
Plug-in the charger ( dont put the battery in )
Turn on laptop and see if it works.
Very Noticable details:
7. Since on of the rare fixes requires to move the lid i tried shaking the screen a bit or pushing it slightly to different directions. This actually does the trick and turns the screen back on ( i am right now typing this after using this "trick"
So, with this one as a hint there are a couple of stuff i have in mind but i am not sure and need help since i am not a technician.
a) There is a loose LCD cable and when i type a little vibration moves it and ends up in a black screen.
b) I read that if you use a flashlight and you cant see your desktop it means its a bad inverter.
c) Can the inverter have a lose cabe instead of the lcd ?
That's all the feedback i could give you that i can recall now.
Currecntly the screen looks ok ( maybe its the certain angle it has after i moved it so i would aprecciate a fast reply before it goes black again
EDIT: Tried to play a game for a few mins and i got the black screen again. Closed the lid so the laptop goes in sleep mode then opened it and it worked. Just for the records.
EDIT#2: Just tried to play a game again. got the blackscreen, shaked the screen a bit and it worked but for the 1st time i get the message " Application has been blocked from accessing graphics hardware" , Can it be that its the GPU after all or maybe drivers?
EDIT#3: Tried to play a game again and it seem to trigger the issue . ( i am currently running the laptop with only the intel drivers installed)
thanks in advance
Sincerely,
Ntas
P.S. Please feel free to ask me any question if you need more information, i am not a laptop expert but i know more than the average person

Hi @Ntas
I have read through your post and it seems there are a couple of possibilities, and I noted that you have already tried several of the things I would normally suggest.
I will however post some of those links anyway for you to review, it is always possible there may be something in one of them that may have been missed or may inspire an idea of the cause. Since you mentioned that sometimes just moving the screen will cause the problem or make it disappear, that does seem like either a loose connection or maybe something like pressure on a part of the display causing the issue. Of course that last part may just mean the display is on its last legs, but hopefully not.
First I will give you a link to the service manual, to help you check the connections. Just be careful to read the sections on precautions, to protect yourself and to prevent any other damage.This manual is also useful in that it lists all the compatible parts, so if the display is defective you could use this guide to help order a compatible replacement if you choose to do so.

E6-00, Screen blacks out as soon as a call is rece...

I'm posting this on behalf of a friend who has asked me to take a look at their E6-00 which has a problem that when a call is received the screen blacks out instantly and therefore she can't see the caller display.
I've read elsewhere that it is an issue with the proximity sensor on the front of the device but nowhere states if there is a definitive fix for the problem.
This did not happen prior to the phone being upgraded to Anna. I have since upgraded it again to Belle in the hope that this will remedy the issue but it's still happening.
Can anyone advise if their are any OTA updates or downloads that will sort this out or is it just a "live with it" firmware flaw?

Try do the soft reset (Restore Factory Settings in the Settings). If it still doesn't work well, try to do the hard reset. Before doing this, please create a backup as the hard reset will remove all your files.
If the hard reset does not even help, you may have to take the phone to the nearest Nokia Care.
Let me know if it works.
If I have helped you in any way, give me a kudos!

Since installing yosemite my computer/screen blacks out, but still running

Since installing yosemite last week, my computer/screen blacks out, but still running. I have since rebooted everything, started from scratch and utilizing my external drive transferred all files/apps back. Did not help, in fact it is getting worse. Computer screen blacks out every 5 min or so and have to power up again. Also, continue to get Java message updates even after all have been updated over and over again. Any suggestions? Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

14" iBook screen blacks out

This is the third time it's done it today and the 5th time ever. My AppleCare ran out the middle of March, so I guess they are right on in determining when it's time to get a new computer.
When it blacks out, it just goes immediately, no flickering, no warning whatsoever. I can still see the desktop underneath the black and I can still move the cursor. I don't know anything what the insides are like, but the apple light on the top of the case goes out when the screen blacks out.
When I closed the top and opened it again, it brought the screen back up right away. But this last time, it took a few closing and openings to get it to come back up, making me think it's going to get worse.
Last week was the first time it ever went black. I initially thought it was falling in to sleep mode and held down the power key to get it to reboot. I'm pretty sure sleep has nothing to do with it, but I set my display to not go to sleep at all today to find out. It's blacked out twice since.
I don't use a screen saver, it's happened on battery and power adapter. Other people have mentioned the fan not running, I can't remember ever hearing my fan run or else it's just so quiet I can't tell the difference between it and the hard drive.
My iBook is a late 2004 model 14" 1.33 and, I just upgraded to Tiger (coincidence?) There have been no other problems to speak of other than the keyboard losing letters, battery needing to be replaced and the usual airport glitches. It hasn't been dropped or spilled on. Any suggestions on how to fix this and what I might be looking at when/if taking apart the screen?

It sounds like you might have a bad inverter cable, especially since it is affected by the position of the display. I think this is just a mechanical failure of the cable caused by many openings and closings of the display.
You might check out the troubleshooting section of the ifixit site and read about the inverter cable and see if it sounds like what is happening to you. I gather it is a real job to replace it. Ifixit and Powerbookmedic would be two good resources:
http://www.ifixit.com/
http://www.powerbookmedic.com/
Since the job is considered very difficult, I'm not sure there are any instructions on how to do this on these sites. But there is another manual that might be helpful:
http://node123.cit.geneseo.edu/~stratton/ServiceManuals/
This is just the index. You will have to find the one for your iBook. Powerbookmedic also has a good manual.
It may also be possible to repair the cable, but I don't know. Spudnuty is the real expert here, and hopefully he will see this and be able to offer you more specific advice.
Good luck!
