Cinema display goes off when USB cable plugged in

WhenI plug my USB/firewire cable into the computer the screen goes black.
I have used this display for years and never had any problems.
The computer is about a year old but both have worked together since they first met!
Any ideas?
I see similar questions online but no reponse from Apple??!!??

What kind of computer is it connected to? Is there anything else connectted to usb? If so try disconnecting them.
Try smc reset.

My display goes off when Battery being charged on Acer E5-511 after upgrading to Windows 10

I upgraded my window 8.1 to Window 10 on Acer E5-511 machine yesterday. I notice that when I switch on power to charge its battery, a beep sounds and display goes off. when power is again switched off the display comes back with a beep again. However, when the machine battery is allowed to charge for some time, either it goes to hibernation mode or stops working since display does not come back even after switching off the power supply. This peculiar problem did not existed when I had used this Notebook with windows 8.1 for past eight months. Can any one help me to solve this problem as i am being forced to charge the battery only when Notebook is not powered on.

Prevent Macbook/Cinema display sleep mode when switching from plugged-in/off

Hello, I've a macbook connected to a Cinema Display. On Energy Saver, all is set to never go to sleep. I'm trying to prevent my macbook going to sleep mode when I plugged off it. Do you have any solution for this?

Hi tjk,
Yes I mean when I disconnect the power supply (that comes from the Cinema Display) the macbook pro goes into sleep mode until i press a button on the keyboard, then it returns into running mode (even if in energy saver all is set to never go to sleep).
I would like that, if there is a power cut in my house, the mbp does not go into sleep mode but continue to be in execution (by means of battery) avoiding sleep mode.
Thanks
Looks like someone already cut in to try answering, but I'll answer the question you asked me anyway. You can read Apple's directions http://support.apple.com/kb/HT3131 and see that unplugging is the cause. It's not really an issue, it's just the way it works.
Contrary to the statement "There's no way around it." you may want to look into UPS (uninterrupted power supply) if it's important enough to you. I have never used one so I am not familiar with them, but by their very nature/purpose, I would think they'd do what you need.

Display goes off when close lid and open it again [Lenovo G580]

Hi everybody,
I have a problem due a new update, when I close laptop lid and open it again, there's nothing on screen (like power off laptop) and webcam's light is on! when turning on my laptop it would be on for a second, but it freeze on this state, I think the problem is with kernel but i'm not sure cause i've updated everything.
And this problem occur in both X and other tty.
I'm not sure it should belong here or I should move it Hardware/Kernel section.
Kernel: Linux GNU 3.14.0-4-ARCH
Xorg-server: 1.15.0-5
Nvidia: 334.21-4
everything is updated.

Display goes off and comes back only when Satellite A210 is restarted

Hi,
Satellite A210 displays goes off now and then and comes back only when the machine is restarted.
Usual runtime runtime 30 or 45 mins
Please advice
# Is this a hardware problem or software?
# Does some one else faced same problem do advice?
Machine is year and a half old runs windows vista basic that comes with it.
I have reinstalled the display adapter drivers also the problem remains same

Hello
Have you tested an external monitor on the notebook?
If the external monitor works fine it seems to be an internal display issue and must be replaced.
Are you running the factory settings on your notebook or have you installed your own Windows version? Before you go to an authorized service provider you should restore the factory settings to determine if its a hardware or software problem. With the factory settings all should work properly and if not in my opinion its a hardware problem.

Airport Express - Noise when USB is plugged

Hi I just bought a laserjet printer and after I plugged the USB cable into the Airport Express, I hear some noise on the speakers of my stereo which is connected to my AEX. When I remove the USB cable everything is ok but with
the USB cable plugged..there are serious noise
I tried with another USB cable but same issue...
Anyone experienced the same issue ?
Thanks
Vadim

If you power-off and unplug the laser printer from power, but still leave it connected to the AX with a USB cable, does the noise stop? If so, reconnect the laser printer to power, but leave it power-off. How about now?
Normally do you have the laser printer and/or AirPort Express Base Station (AX) plugged directly into a wall power outlet. If so, the same outlet? ... or do you use a power-strip for either?

Why does my iMac display go off when I am starting up or waking up my machine from sleep..

Why does my iMac display go off when I am starting up or waking up my machine from sleep..?
When my iMac goes to sleep I then later try to click the magic track pad or keyboard and it will usually then show the initial password entry login screen and then go off. The machine is still on but the display is black and will sometimes flash up the screen again if I press the magic track pad or keyboard but will then black out again..

Well, there are many different reasons why it does this. It might shut off due to power voltage problems, system overheats, or there is a System Problem. The reason it might be hard to boot up is because your power button might not work properly or your system hard drive is damaged.

My iphone 3g running ios 4.2.1 goes off when it is idle

i need help,
My iphone 3g running ios 4.2.1 goes off when it is idle and i have to reboot it before it starts work.
it does not go off when it plays music..... or plugged into the PC.

It's likely running slow because of iOS4, not because of apps being open. Standard troubleshooting...
Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
If still a problem restore from your backup.
If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
You'll most likely need to restore as new to get it running as good as it can. A 3G will never run as good on iOS4 as it did on iOS3.

Display goes black when in a call

I have noticed an annoying feature with my Nokia N8: The display goes black when in a call (holding the phone to my ear). When the call is finished I have a difficulty to close the call. Is this a Nokia special feature for saving battery that can be turned off or is it an error?
Solved!
Go to Solution.

Hey Is1987Is! Sorry you are having this problem.
It is normal behaviour for your screen to go black when held near your ear.
Is your screen just not coming back on once you finish your call or take it away from your ear?
Incase it is a bit more of a serious case of your phone having a black screen after hanging up a call. You can try this troubleshoot.
To make sure your proximity sensor is not over sensitive causing your phone to have a black screen, during incoming and outgoing calls aswell as alarms.
First thing is try to verify sunlight/IR oversensitivity with a typical desk lamp.
This could be done by making a phone call (or setting alarm) and putting the phone under the desk lamp when the phone is ringing (or alarm activated).
If phone is oversensitive to IR, display should go blank caused by IR radiation from desk lamp.
If this is the case you should take your phone to your Local Nokia Care Point, and they will be able to fix it for you!
I hope this helps, let me know if your phone goes black screen during an incoming calls when you test it under the lamp!

Sattelite 1800-752S - the display goes off

Hi everybody.
I have a satellite 1800-752S.
SInce a ew months ithas a wierd problem: the display goes off. If i press and quickly release the lid button it comes back on, but after that goes off again. SOmetimes ot goes off immediately, sometimes after a few minutes, or even hours. SOmetimes it keeps being on when I am running from battery, and annoys me on AC, sometimes the versus. It works quite well, after I turn it to standby or hibernate a few times, and after a restart it annoys me.I have updated its BIOS to the lates from this site, that wouldn't help. I assume it is a hardware problem, because it is the same problem under Linux, and I have tried to install different verisons of drivers and Windows (not only the one from the Recovery CD). Did anyone have the same problem before. Any help will be appreciated.
Thanks a lot
Roman

Hi,
I think you are right, it's a hardware problem. But to be sure, try to connect an external monitor. If it works without problems while the notebooks display goes off, then it must be a hardware fault.
I assume it's a problem with the FL-inverter. You have to give your mashine to a Toshiba service partner for repair.
Bye

Display going off

My display goes off after starting the pc, sometimes after 5 mins and sometimes at the BIOS setup, and even during Windows startup repair. RAM and PSU are fine as I am using them on a different motherboard and they are working fine. Also when the display goes off, sound doesn't go off immediately, I can hear background music and then there is some noise and sound also goes off, HDD led stops blinking afterwards. Sometimes, HDD goes off along with display. So is the culprit graphics card or motherboard or something else( The other motherboard which I tried, (Nvidia 630i) had onboard VGA and it worked fine)
My specifications:
Motherboard: MSI P45 Neo-F (601-7519-010) no OC
RAM: 2X2GB Corsair DDR2
HDD: WD Caviar Green WS6400AACS, 640GB
PSU: Corsair VX450, 450W
GFX Card: ATI Radeon 4850, 512MB DDR3
Operating System: Windows 7
Processor: Intel E6750, 2.66Ghz

It is highly recommended to use identical modules. Using non-identical but similar modules either works properly or it doesn't. The answer depends highly on what specific memory combination is going to be used on what system. So, basically, if you can avoid mixed configurations, avoid them. If you already have the modules there in front of you, go ahead and simply test it. There is no risk of damaging anthing (well, at least not in general).
Quote
but since pc is booting properly, motherboard should be fine right?
Probably --> which means that I personally believe that a problem with the video card is more likely to be the cause. That is why it makes a lot of sense to start testing on that front first. However, the mainboard is not necessarely out of the equation. It is not very likely, but still not totally impossible that the mainboard is the cause for your problem.

Is there any way to keep the flash from going off when you receive a text or other notification?

I have an iphone 4s. Is there any way to keep the flash from going off when you receive a text or other notification? I keep it next to my bed at night and keep thinking there is lightning when something comes thru. LOL

Go to Settings>General>Accessibility and turn LED Flas for Alerts to Off.

When FT is full screen, camera goes off when swiping to a different app

When FT is full screen, camera goes off when swipping to a different app or the desktop. This is frustrating to the other person. We were having a discussion and I said I wouls look it up and when I swipped to Safari, the camera went off. It makes the other person think the connection has been lost. Anywhere to report issues like this to Apple?

In reading other threads, I found a few that recommend a hard reset to solve the issue. I have tried it, and thus far haven't expereienced the problem again. Hopefully that's it then
