Screen light decreased suddenly

The Screen light of my macbook pro decreased suddenly, l just moved from desk to bed, it was turned On, and plugged in with the electrical cord, don't understand why it happened! it's new and never happened this before.

There are two sets of power-saver settings, one for the power adapter and one for battery alone.
On battery alone, the screen will dim to about half brighness if you do not use it for a minute or so.
All of these settings are adjustable in
System Preferences > Energy Saver

If the image is too dark, adjust the brightness. In General Settings choose Brightness and Wallpaper and slide the slider.

My macbook pro's screen display has suddenly gone into a strange colour setting where everything appears in a kind of infrared colour palette an I can;t seem to change it back. It's the same for all icon and websites, does anyone know how to restore?

Wow! I think I had this same issue just last night.
I was cleaning my macbook pro retina on the outside. Then I opened it up and was wiping dust off the monitor and I can't pinpoint exactly when, but the colors changed suddenly. It looked super strange, it was like green halo's and it looked worse when looking at it at an angle. Of course I took no pictures!!! I was freaking out that my 2 grand laptop was busted and I somehow removed a protective film or something.
But I digress... The image looked very green and spacey, it was almost a neat effect. After about 5 minutes it started to look a little more digital though. There were straight lines of this halo effect on the edges and top. After about 10 minutes it turned into a predominate issue with the blacks on screen. I could open a web browser and it was unnoticable on a white background. After about 15 minutes, you could only barely see the green cloud effect if you looked at the monitor from an extreme angle. After about 20 minutes, it was completely back to normal, I almost feel paranoid like I see a halo or something strange. But I believe that might be all in my head now.
So yerp, lemme know what you guys figure out.

Screen light auto turn dark when I use program/web with background dark in windows 8.1

Hi there,
I used HP Pavilion dv6t-6000 CTO Quad for 3 years.
CPU: Intel core i7-2630QM
GPU: AMD Radeon 6490m
It build in windows 7 and I manual install ( fresh install ) windows 8. It's fine. But when I upgrade to windows 8.1, it have an issue and I really hate it.
When I use "Sublime Text" ( with background is black ), the screen light is become darker. And when I back to ( e.g: a website with background is white ), the screen turn back to lighter.
I tried many ways, included 4 ways here but it's NOT WORK.
NOTE: When I used Option 1 ( upper )
1. Open PC settings, and click/tap on PC and devices on the left side
2. Click/tap on Power and sleep on the left side, and turn on or off Adjust my screen brightness automatically on the right side under Brightness.
==> It's NOT SHOW button "Adjust my screen brightness automatically". It mean: I have NO built in auto brightness sensor.
I think this issue is about AMD driver or Intel Graphic driver.
Is anybody have idea???

i grasp that after updating your system from Windows 8 to 8.1 you are having an issue with the display going dim.
You have tried some steps you located on the web but there was no change.
Windows 8 an 8.1 are not supported Operating Systems for your notebook. This does not mean they will not work only that HP has not tested it and therefore does not supply updated drivers. You would need to check the manufacturer's site for any updated drivers.
Downloading or Updating Software and Drivers for HP Computers
When I checked the driver page for your notebook I did notice there is a bios update, have you done that?

As a bios update does have a potential to cause damage I suggest contacting HP support for assistance with that process.

How do i retrieve data from a powerbook whose screen lights up but displays nothing? I have a firewire and a second powerbook...

how can I retrieve data from my old powerbook? It's screen lights up, but displays only pixelated blankness. I have a second powerbook and a firewire cable....

It would probably be correct to assume that both PowerBook computers are equipped with FireWire. The article below could possibly be of interest to you. With a bit of luck, the old computer will be recognised.

Otherwise, it may become necessary to open the old PowerBook and remove the hard drive. The drive can then be connected to an appropriate external USB adapter, and read via another Mac.

Try this First... No Data will be Lost...

Release the Buttons...
If no joy... Try a Restore...
1: Connect the device to Your computer and open iTunes.

HT1386 After upgrading itune on my computer to 10.5 and after upgrading to ios 5 on my 3g iphone, and after backup on my computer, my iphone simplay cannot open up. The screen lights up but it I keep getting the message, "there is no sim in your phone. Th

I have upgraded itunes on m computer to 10.5. When I connected my iphone to the computer I was told that ios 5 is ready to be downloaded, and that I should back up my iphone before doing the download. I did. Now I want to get my iphone back on and it just can't . The screen lights up, i select language and network but it tells me that my phone cannot be activated because the activation service is temporarily unavailable. what do i do?

Try a Hard Reset.....
Press and hold the Wake / Sleep button AND the Home button at the same time, keep them both pressed until the Apple Logo appears on the screen, it can take 10 or more seconds. Ignore the swipe to turn off message.

When I press to the left of the home button, the screen lights up

When I press to the left of my home button, the screen lights up as if I were pressing the actual button. This causes Siri to pop up randomly all the time and my phone keeps accidently taking screen shots. Should I take it in?

I was a little confused when I first read this, but I think I understand what you mean now. The bottom left part of the glass on the front of the iPhone, by the home button, can cause it to act like you're pressing the home button. I do not experience this issue on my iPhone 5. This is probably a small defect in your iPhone. It isn't major, though, I'm sure if you visit the Genius Bar in your nearest Apple Store, you can get advice from the experts on what to do.

Screen lights up white but nothing shows?

when I turn on my iPod the screen lights up and when I touch the wheel I can here it clicking but the screen doesn't show up except for lit up white. The music does play but does anyone know what I need to do to get my screen fixed?

I don't know whether this will help because it's not specifically for nanos. Worth a try.

Screen Lights up while I'm on a call

Why does my screen light up when I'm talking on my Iphone4? I keep muting, hanging up, putting tne person I'm speaking with on hold....this is extremely annoying and makes me regret buying this phone! Why is this happening? What should I do?

I never think of myself as suffering from the proximity sensor issue but the truth is that on the odd occasion that I don't have my bumper on my phone I do sometimes mute the call with my cheek. This never ever happens with the bumper on the phone.

Screen light burned out

My screen light seems to have burned out. My computer is probably about 6 years old, so I was wondering if this can be fixed?

After reading a couple of the other thread (such as "17" PBook display colors are off .. bad" and "screen not working since last update") I was able to fix the problem. I think what must have occurred is the recent computer update some how reset some of my display preferences and it turned the brightness way down. All I did was go to System Preferences then Displays and adjusted the brightness.
Thanks to those that posted the other threads

No screen light Nano 3rd

No screen light Nano 3rd

1. Make sure the Hold switch is not operated (i.e. you have it set so that the Red is not showing on the switch.
2. Press and hold the Centre and Menu buttons at the same time, keep them pressed until the Apple Logo appears on the screen (this can take a while, over 10 secs, so keep them pressed).
That should reset the iPod, if it does not work, then try step 2 again with the Hold switch in the other position.

N97 screen light

Hi on my n97 whenever the screen is slided out the screen light doesnt seem to go off after 60 seconds ( what I have it set to ) however it does go out if the phone is NOT slided out. and the next morning I have no battery left.
thanks

The problem still persists with FW 22.0.110. Sometimes plugging in a headset seems to cause this particular "flavor" of freeze (one of many with the N97).
Recently however, I have discovered a new problem. The display backlight no longer turns off.
Timeout is set to 45 secs, auto-keyguard is on. Recently the light just stays on after placing or receiving a call or reading/sending texts so when I am at home or at work and just put the phone on the table and walk away the battery drains very fast with the lights on.
The usual fix (remove and reinsert battery) does work. Nevertheless this is just one more added annoyance of the N97.
Ever seen a black lemon? They turn black when they rot. My N97 is black. 'nuff said

Screen light decreased suddenly
