LED screen goes out when in use

Lately, my ibook screen suddenly goes dark while in use. It seems to be random, not linked to any certain behavior.
Anyone else having this problem?

Hi, Erin.
Does adjusting the angle, opening it or closing it a bit, make a difference?
You could try resetting the PMU. The PMU (Power Management Unit) has control over the backlight, so resetting it may help.
Please let us know how things go for you.

Screen goes out when cover opened

I have a white Macbook. When I open the cover the screen goes out unless it is held at a certain angle.

It's one of four things and the liklihood in this order:
1) Inverter Cable
2) Inverter
3) Screen
4) Logic Boarad
If you're Macbooks under warranty take it to an Apple Certified Technician (Apple Store) and have them take a look at it. If not, and you can't afford to repair it, you're welcome to take a gander at repairing those parts. If you have the time, and can figure it out, try opening up the chasis reconnecting to cables to the monitor, as on some laptops they're taped on and eventually come lose.
This will likely void any active warranty.

ENTIRE screen goes grey when I use siri.

Before ios7 when I held the home button to activate siri, I was still able to view the page that I was on. So, if there was a phone number that I needed siri to dial (I realize you can click on most phone numbers and iphone will ask whether you'd like to call the number you clicked - but there are many web pages out there where his feature simply doesn't work - clicking on the phone number elicits no response from iphone), I would hold down the home button and tell siri to dial the 10 digit number that I'm looking at on the screen. With iOS7, holding down the home button to activate siri turns the entire screen grey, so I can't read the number off. I literally had to go and grab a pen and paper, wrote the number down while the screen wasn't COMPLETELY GREY, then ask siri to dial the number as I read it off the pad of paper. This is not only inconvenient, it's completely idiotic. What's the point of the grey screen???

Simplistic in design, does not always help with use.
Simple icon....or icon that doesn't say anything useful.
clean black screen.....nice to look at but not useful.
clean icons, nice to view, but not useful in determining what the icon represent.
many apps per folder, but only to allow a few to be viewed, thus making many mini folders/pages within a folder.
simple, elegant, etc....doesn't mean it makes it better or easier to use.

No Entry sign on start up screen goes dark when I use utility disk

HELP!!!!
Everything was fine no strange noises or bad behavior but when I started up my MacBook Pro I get a "No Entrance Sign" (or what-ever it's called).
I have unplugged all the peripherals (external drives, monitor, etc) but to no avail.
When I tried booting from a Utilities disk (Disk Warrior) the screen went dark and I could not see the instructions (it was there but very dark and dim).
Is there anything I can do or am I doomed?
HELP!!!!
Thanks.

Er, it looks like a "No Entrance" sign. It's OK the cats at The Genius bar understood - they call it a "No Entrance" sign too. It basically means you're screwed and need to get a new internal drive. Luckily I managed to make a rushed back-up so things are not too severe (just expensive).

Hi frank at luray,
Does this issue occur with any file that you try to send, or do you find that it's specific to one file? If it's a file-specific error, and the file is large, please try sending the file via Adobe SendNow. (You can sign in to Adobe SendNow at Sign in or create an account | Adobe SendNow using the same credentials you use to sign in to Adobe Send.)
Please let us know how it goes.
Best,

It's possible you've got a 'hot corner' set up. If you have and move the mouse to a certain corner of the screen it'll do as you describe. Have a look in System Preferences>Mission Control, bottom left of the window click on the 'Hot Corners' button and see if there is anything in there.

The screen goes out of sync, how can I fix this?

when I start the server, the screen goes out of sync, how can I fix this?. The server has no video card.

What do you mean by 'out of sync'?
Try running the 'kickstart' using Send UNIX Command or while logged in to that server (ssh etc):
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -restart -agent -menu -console
You might also want to trash /Library/Preferences/com.apple.windowserver.plist from the server..

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!

Hi Vaish,
I’d like to help you with this issue as we can try to increase the Brightness of the screen from the power options while plugged in,
And then please if still the same we can try to uninstall the Lenovo Energy management and reinstall it back:

Lenovo Energy Management for Microsoft Windows 7
Hope the information helps. Let us know.

My iphone screen goes crazy when it charges

Hey there,
Whenever I charge my iPhone my screen goes crazy when I touch it. If i'm typing whilst its charging it clicks random things and deleted what i've typed. The phone works completely fine when its not charging and I haven't had any other problems with it. I have the iPhone 5c iOS 7.1.1 (about to update after this post).
If anyone could help me that would be great!
Ps. Someone posted a video and my phone does the same
https://www.youtube.com/watch?v=QbsNCjbs-xg

I have the same exact problem and I use an Apple charger and lightning wire cord. Resetting the phone doesn't work and neither does shutting it off and turning it back on. It is infuriating to say the least, especially because this stupid phone spends more time on the charger than off. The battery is crap.

How you can find out when someone using your icloud account

how you can find out when someone using your icloud account

Someone on a different device only needs to sign with your iCloud ID and password in order to access your account, they don't need to answer any security questions if they have your credentials. If you think this happened, you should change your iCloud password as explained here: iCloud: Change your iCloud password. After you change the password, you will need to change it on your devices by going to Settings>iCloud>Account and entering the new password.
If you want to inquire further about this, contact the Apple account security team: Apple ID: Contacting Apple for help with Apple ID account security.

Iphone 3gs screen goes blank when it rings/gets a text

My iphone screen goes white when i get an incomming call. I can answer it if i slde my finger across the general area where the answer switch will be.
In order to view the screen after the iphone has locked I have to hit the home button followed by the power button 3 times.
Does anyone know if this can be fixed? If not will i be able to get a replacement. I'd be willing to pay as its out of warranty?
Thanks in advance for any help you can give me!

Remove your case and see how it works. It may be blocking the proximity sensors that turn the screen off/on during a call.

N95 screen goes black when in between open and clo...

Just noticed today that the screen goes black when sliding open or closed. Screen comes back on when slider reaches open or closed. Is this like the blank screen fault that affected so many N80s ? I'm very disgusted that I have to pay to fix my 16month old (expensive) N95 for an ongoing issue with Nokia sliders that they HAVE NOT fixed in their design. Very poor support Nokia.

Scott your grieviences are justified... but there is always a solution to a problem...even if this is a strange problem to be handled in an off the routine way, be it so... once again best of luck! not blame nokia for anything...nokia rules as always and nokia's productions have become very slow now :-( i wish they could make trendy phones like sony, sleek and stylish with new features.in some ways, nokia gets a little boring with no new features.. i dont feel any differnce between the nokia n95 8gb, n96 and n85(which i currently own)!
Scott lets hope for the best :-)
