Screen Brightness Keeps Dimming

My new Sony SVS131290X laptop will not keep it's screen brightness lit. It keeps dimming by itself. I have tried setting the function + F6 key, going to power options and adjusting the brightness there, and also tried advanced power options. It dims after 30 seconds. Has anyone else had this problem?

Hi everyone, I just recently purchased a Sony Vaio Pro 11" and I have been struggling with this issue the past 2 days, and now I have a proposed solution! Prior to doing this I had tried two things (outlined below) and neither of them fixed the issue for me, so if you are in the same boat this might work for you too. WHAT WORKED for me was going to the graphics properties control panel:Right click on the Desktop home screen and select "Graphics Properties" > click the "Power" tab > click "On Battery" > and under "Display Power Saving Technology" click OFF That fixed all my auto-brightness adjusting woes. Hopefully this helps someone else The two steps I took that didn't quite work:1. Went to Vaio Control Center > Image Quality > turned OFF the auto brightness = still had the dimming issue2. Went to the Start screen, scrolled down to the apps section and in the search bar > typed services.msc > opened up Services > clicked "Sensor Monitoring Services" > went to the drop down menu and changed from "manual" to "disabled" and restarted my laptop = still had dimming issue

My screen light keeps flashing

My screecn keeps flashing like a strip light on the blink any ideas?

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.
- If still a problem, it's likely a 3rd party app or a hardware issue.

Screen light dim?

Just yesterday after adding new albums to my ipod, when turning on the screen (while playing music) the screen light was dim. I tried several times to turn off and on, sometimes it was fine, sometimes it was dim. And when it was dim it could last a second or a lot.
Today as it keeps happening, I removed the new albums from the ipod, and tried again with the older albums and no dim light. just perfect.
So? albums have something to do with the screen light? is a problem of the tracks? or the ipod?
Any help would be appreciated, thanks in advance

You know that there is an auto brightness function on your Touch, do you? On the front of the Touch, at the top left, just above the display is a small circle. This is the brightness detector. The setting for it is in *Settings/Brightness/Auto-brightness on or off.*

RANT: Why does screen keep dimming even when "DIM" is disabled?

ARGH this is buggin' me!
I turned off the dim under custom in energy saver. i am reading a document and it keeps dimming and it's annoying as doo doo. anything i can do?

What about the option of "Automatically adjust
brightness as ambient light changes" in
Preferences/Displays?

William - anyone with this problem I can guarantee
shut off every screen dimming option.
I have this issue. It seems to be intermittent.
What seems to improve it - Restarting, or unplugging
and re-plugging in the mag safe charger.
These have been my only solution. I have even turned
off all display changes for battery power so that
there shouldn't be any "confusing" factors for the
computer.
I wouldn't care so much about this issue if it wasn't
for the screen whine with decreased brightness.
I trust apple will fix this with software or firmware
updates.
I checked my 1.67 PB 15", it does what is being described. Software?

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.

Why does my screen keep dimming and brightening?

I'm just sitting here in front of my fire during a mid-March snow storm in Maine, and my screen keeps dimming and then brightening. It's getting quite annoying. What is going on?

OK, I figured it out - it's the auto brightness adjustment. Found the answer in the pane to the right of my comment.

T400 LCD screen is very dim, but icon lights for HDD, etc. are working

Hi - I'm wondering if anyone knows what the issue with my T-400 would be if the LCD screen is very dim. Details include:
- When I boot up, there's a faint outline of what is going on, but barely noticeable since the whole screen is very, very dim
- Video card is working okay, because I can operate the laptop when I plug in an external monitor
- The icon lights for HDD, power, battery, etc. are still working
Thanks so much for the help.

First a question: Is it a CCFL backlight or LED? If it is a CCFL, it could be just the inverter, which is a lot cheaper than the panel. If the CCFL bulb goes out, usually (but not always) there is a red tint to the screen for a while first. The LED backlights are less likely to blow and there is no inverter. (The LED backlight is DC and the inverter convers the DC to AC to drive the CCFL bulb) Do you know which kind of backlight you have? If you don't know, send me your full model and serial in a pm and I'll look it up. Don't post it in the open forum. Also, what were you doing when it went out? Were you doing anything except normal work, like taking something apart or hooking something up?

Lcd screen keeping 'dimming'

I'm sure there is an easy fix for this.
I notice if i haven't used my computer for several minutes, the screen dims, and then quickly brightens againa as soon as i touch the trackpad or any keyboard button.
I have gone into the options listed under the battery icon. I have tried to set it to best performance, it still seems to occur, i have gone into custom and and energy saver and set the sliders for putting the screen and computer to sleep for both the battery and the power adapter to 15 minutes. I have locked the settings.
It still seems to occur.
Peculularly, i often go back into this area, and the lock is UNlocked again, without me entering my password.
Is the screen supposed to dim? I find it annoying and would like to turn it off.

I can understand your frustration with this, and with some of the responses...
Check out that link in this thread, I have outlined "improvements" to the situation in the last post.
There is no official solution, and apple did not address my question during my last repair.
I will be setting up another pro care session within the next month and will try to reproduce this for them.
Supposedly this has been going on since the Powerbook Era, and is nothing new. Unfortunately I've only noticed it with the MacBook Pro, and never with my powerbook.
Keep an eye out, and eventually we will find the source of the problem.
Now here's the REAL question:
Does anyone know if there is a log (say in console) of when/why/how the screen dims, much like there is a log of system sleeps???
I think that will answer our question, and find the source of our dimming despite all the appropriate settings UNCHECKED!

Why does my screen keep dimming?

Screen on macbook keeps dimming after a few seconds, even when I put it at the brightest and I'm in the middle of using it.

If that doesn't help, perhaps this is your cause:

It doesn't do it on Explorer or while in Windows.
It is only happening since I upgraded to 4.01
It happens even on this page if I stop typing or moving the mouse.

Symantec have released an update for Norton 360 to make it compatible with Firefox 4, for details see http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20100720113635EN&ln=en_US

My screen keeps dimming automatically

My brand new Macbook Pro's screen keeps dimming the screen all the time regardless of which setting is it on. Its the first time it does that today and it's so annoying!!!! I have the following options: Put the hard disks to sleep when possible, slightly dim the display when using this power source, automatically reduce brightness before display goes to sleep and restart automatically if the computer freezes.... The only thing that is check marked is Put the hard disks to sleep when possible and automatically reduce brightness before display goes to sleep... Any advice? I googled a bunch of stuff but I don't have the options they give to help my problem such as un check the automatically adjust display or what not...
Thanks

You have to go to System Preferences > Displays (not Energy Saver where you were).
If you really don't have it, and you have an external display attached, that's the reason why. If that's the case, let me know, and I'll give you directions to do it.
