Brightness adjustament problem

When i start up my iBook it shows on screen the brightness level and when i move the iBook it goes out and when i adjust the brightness using the F1 and F2 the brightness selfadjust to the maximum level every time after i adjust.
I´m thinking that some button is stucked on...
I don´t know if could be this.
Please help me!!!!!!!!!!

And one more thing that i forgot...
when the brightness level displays on screen i can´t do nothing more cause if i click on Finder, for example, the cursor roll out for every option and do not stops until i click on desktop or out of finder.
I´m thinking remove the keyboard and look for something wrong.
Before i´m looking for a better choice,
i don´t no but this seems like a hardware problem and no software problem do you agree?????

Brightness-adjust problem

Brightness adjustment on keyboard not working for Thunderbolt Display in Bootcamp (Win 7 64-bit).
I'm using a 27" Thunderbolt Display hooked-up to my Macbook Pro 17" unibody early 2011 in 'clamshell mode', i.e. with MacBook Pro fully closed in a Twelve South BookArc Desktop Stand; therefore using Thunderbolt Display ONLY.
When using this setup in OS X Lion 10.7.2, then there is no problem whatsoever and the external Apple Bluetooth keybaoard is able to adjust the Thunderbolt's display brightness without a hitch.
However, when using the exact same setup but booting into Bootcamp (Win 7 64-bit), then the problem starts and the Apple Bluetooth keyboard is unable to change the Thunderbolt Display's brightness. After re-installing the current-to-date Apple Windows Support software (and drivers) three times, I eventually got the little screen brightness symbol/icon and level-amount dashes to finally appear and reflect how much brightness is being applied, however the screen does NOT actually change brightnes.
It appears that the display drivers within OS X are correctly telling the Thunderbolt Display to change its brightness when being adjusted within OS X Lion with the MacBook Pro 'closed' in clamshell mode; but the display drivers are faulty within Bootcamp and are not actually telling the Thunderbolt Display to change its brightness when being adjusted within Bootcamp... i.e. it's not telling the Thunderbolt Display that its OK to alter brightness because MacBook Pro is 'closed' in clamshell mode and therefore not using its own screen (not switching controll as it does in OS X).
I know you can make the more long-winded adjustment method by running Bootcamp Control Panel and making adjustment via the brightness slider, however this is far from practical as it cannot be done on the fly and therefore cannot be done from say within a game as your playing.

Hi, Try the following suggestions in the order listed below. 1. Hold down the Windows key and press R. Into the Run box type devmgmt.msc and hit enter. Expand Monitors, right click the 'Generic PnP Monitor' and select Uninstall - click Ok in the following prompt. When done, restart the notebook. Let Windows fully load for a few minutes and then check if the brightness can now be adjusted. 2. If it still doesn't work, try using Recovery Manager to reinstall your original Intel HD Graphics driver - the procedure for using recovery manager to reinstall specific Software or Drivers is detailed in the document on the link below. Reinstall Specific Drivers Using Recovery Manager - Windows 8.
After the reinstallation has completed, restart the notebook.

ENVY 15 - 3040NR Brightness Adjust Problem After upgrade to Windows 8

I agree removing windows 8 is not a viable solution. Also, the Windows 8 drivers have been released and they still don't fix the problem.

Hi, I also have a HP Envy 15-3040nr and cannot for the life of me get the brightness to adjust at all. I'm using the most recent drivers from dec 10, 2012 still nothing. It's bad enough you lock us out of advanced bios settings as far as clock and bus speeds go, but then you make us have to go through your website to get drivers that's already out of date on debut. No one pays $1200 for a laptop with dedicated graphics and expects to be unable to reduce brightness. Over the course of the time I have had this laptop and has released well over 10 updates yet your engineers have only produced 3 hp certified driver and 2 were based of the same build. What are you guys doing wrong that Asus, Lenovo, even dell can get this kind of thing right. We need real solutions for the amount of money involved not half-assed responses like " uninstall windows 8 and go back to windows 7 " . There has to be a engineer that actually cares enough to fix this !

HP Envy q002la Brightness adjust problem

Hi, recently I bought an HP Envy 15 q002la, Windows 8.1 (64bits). Everything worked well, but suddenly the brightness functions stopped working. So brightness got stuck (at the brightest point). What can I do to fix the problem?. I checked driver updates, but all the drivers are updated. I used the buttons and Windows control, but none worked, brightness still stuck.

Windows 8 Pro Upgrade Problems (Switchable Graphics, Screen Brightness Adjustment, etc.)

Hi guys! I hope you can help me with this.
My laptop is a Lenovo U400 bought last April. I upgraded it yesterday to Windows 8 Pro.
The Upgrade Assistant detected incompatibilities on the following softwares (I'll be mentioning only those I had problems with after the update.)
-AMD Catalyst Install Manager
-Catalyst Control Center
-Lenovo Energy Management
-Cypress Trackpad
After the update, the following problems occurred
-Windows kept prompting me about the incompatibility of Catalyst Control Center and Lenovo Energy Management
-When I check the Device Manager -->Display Adapters, My AMD Radeon HD 6470M was changed to HD 7400M and has an exclamation point on it indicating a problem. When check Properties it says, "Windows has stopped this device because it has reported problems. (Code 43)"
-I can't manage switchable graphics because the AMD Radeon driver has been stopped by the OS and Catalyst Control Center doesn't work. It says, "Catalyst Control Center cannot be started. There are currently no settings that can be configured using Catalyst Control Center."
-My touchpad works but does not support multitouch functions.
-Screen brightness adjustment stopped working both on hotkeys and Power Options.
I tried the following actions to fix the problems:
-Downloaded the new softwares from Lenovo Support but the Catalyst Control Center and Cypress Trackpad still doesn't work. I also tried installing driver software from the AMD site but it still didn't work. [FAILED]
-I tried to use the Cypress Trackpad software for U300s/e and it fixed the problem with the touchpad [FIXED]
-Installed the Energy Management software for Windows 8 but when I click the 'Optimized Battery Health' button, it keeps reverting back to 'Maximum Battery Life'. [PARTIALLY FIXED]
-Resorted to 3rd party software to fix the Switchable Graphics (Catalyst 12.11 Beta from leshcatlabs.net) and it fixed the switchable graphics problem as well as the Catalyst Control Center problem. This is temporary until a working solution or update is available. [TEMPORARILY FIXED]
-All actions trying to fix the Screen brightness adjustment didn't work. [FAILED]
Please do help me on this. Thanks in advance!!!

Yes I own U400 too and I'm using it now. To many forums been read, can't remember which one. Basically, u have to clean AMD and Intel drivers that come along with Win 8. Why? Because the Win8 driver database will lead the device ID "DEV_6760" (if you looking at display adapter device properties) to HD 7400 series instead of HD 6470M, again why? At the bigining only the HD 7400 series already "certified" by Microsoft, while the 6470M out of somewhere. Current CCC (or else) + 6470 drivers, contain also driver for 7400 series in same packages (at least until now, hopefully near future they will release an update). So you can gues where the windows will lead to? Yes 7400 series (certified one). This will explain also why the Energy Management didn't work to= "missing identifier" or we can say "hardware not match".
You have to find a "fix" driver which contain only HD 6470M and install it manually trhu "Have Disk" option, after you claan all AMD and Intel driver. If you success, then install the CCC from Lenovo Support and from ATI ( I use 12.11 Beta8 Net4 CCC - this is a must), but remember to unchek the AMD Display driver when you install both CCC, and leave the rest checked including Intel Component. Then you can download install anything you want =).
Leschat's driver did't work on my and "harm" the system. Believe it or not, I found the AMD 6470M standalone driver on HP website. They call it "SoftPack", which actually contain CCC software.
It's quite tricky thing, that's why not everyone willing to try. But I think it's worth to try, as the risk is not too deep, just backup anything befor you do it. Cheer

I am trying to use the brightness adjustment on a grayscale photoshop CS6 file. The preview shows the adjustment working and changes the brightness, but when you click to apply the change, it does not apply the adjustment. I have run into this problem before, although rarely, with some other files over the years and with earlier versions of CS. I would like to know how to overcome this problem?

Brightness auto adjusting problem with Toshiba 39l22U.

I own a Toshiba 39 inch LED 60hz 1080p hdtv (Model 39l22u), and I've had nothing but problems for months. I bought it back in January of this year for 400$ at BB and I initially had no problem with it, I thought that once I figured out the best picture I'd be satisfied, so I never bothered to return it. My problem isn't the picture detail, it's actually really nice on Bluray movies. My problem is something else. The brightness sort of adjusts when you move your camera angle around in video games. Unfortunately not many own this tv and the ones that have it and reviewed it said it's fantastic and has no problems, not a single mention of this.
The overall brightness of the TV adjusts to what you're looking at in game. For example, looking down at a road on Grand Theft Auto V the road gets brighter and the sky gets darker, then when I look up the road gets a bit darker while the sky gets brighter. While driving in a car at fast speeds can be an eyesore because the camera is moving and the brightness is adjusting a lot. It's like the TV is auto adjusting the brightness for some reason.
I also had another problem, but I was able to solve it. Dark areas would dim when the camera's in motion then go back to normal when you stop moving the camera angle in games. This was solved by turning the brightness up and it disappeared. So naturally I thought that maybe by turning up or down on things like the backlight, contrast, gamma etc that maybe this would go away, but it's still there.
This TV doesn't have many extra settings when it comes to Picture. Aside from the basics you have Dynamic Contrast and Dynamic Lighting, nether of which cause this problem as it still happens when I turn both of these off. There's no energy saving feature aside from powering down when not in use for a period of time. I'm stumped here, ether my TV is faulty or there's some sort of auto brightness adjust built into the TV that you can't change. I've also tried every different setting in my Xbox 360's display settings, but it's still the same problem.
Unfortunately I can't find out much about this TV, only a few reviews in which people say the TV is great. Which makes me think my TV is faulty.
Is my TV faulty? Or Is there something that could be causing this? Any ideas on what the problem could be?

I'm unfamiliar with that problem. If you can't solve your issue and no one in the community can help, contact support to speak with a tech support agent at (800) 631-3811.

Brightness adjustment in Windows 8 does not work properly on rMBP

Finally Apple has released 10.8.3 and the new bootcamp officially supports Windows 8. I have used it for several days but only one little thing. I don't know if this happens to other users.
The brightness adjustment just has three levels. Dark, level 1 brightness and level 2 brightness. The screen cannot be brighter after these levels. Also there is no Apple brightness level figure showing, instead the windows 8 brighness level figure shows, and the screen goes dark when the brightness level bar goes only half way down.
Here is the example. If I hit the brightness minus button again, the screen goes dark.

Oh I know what the problem is. I tried to uninstall the light sensor driver and everything works fine! In Windows 7 I used to disable the light sensor feature so there was no such problem. I tried to find such setting option in Windows 8 but nothing found so I just uninstall the driver.

Brightness Adjustment in Windows XP

I'm running bootcamp with windows XP NTFS partition on the macbook pro core duo with ati x1600.
Whenever I adjust the brightness the first click down from the max brightness "jumps" down to half as bright, and then the rest of the clicks, with the brightness adjust buttons, gradually get darker. When I boot OS X, the brightness adjustment is gradual the whole way.
I checked to see if maybe it was just because I wasn't running Leopard, but my mom is running tiger as well, and her brightness adjustment in Windows XP is gradual, the way its supposed to be. She also has the core 2 duo macboook pro with the nvidia 8600gt and not the original core duo like me.
What could be causing this problem? Are the ATI drivers not the most compatible with bootcamp or something? I'm using their drivers on the amd.com page specifically made for bootcamp->core duo.
Any help would be appreciated.
Caleb

I believe that this is an existing issue. I am also using a Macbook Pro with ATI x1600 video card. The brightness adjustment is 50% at first click and then gradual. I too have all the recent updates as far as the drivers are concerned.
To confirm your statement on Nvidia video card.... macbook pro's equipped with this card do not have the brightness adjustment issue that we are reporting.

Nokia 6300 brightness adjustment

I bought a 6300 2 days ago but till now, i cant find the menu to adjust the brightness of the screen.
The other problem is I bought it from O2 - UK (pay and go), but when I put an orange sim card in, the phone requires a restriction code. But when I put put an O2 sim in, it works very well.
Can anybody help me the find the code to use all kind of sim card please?

For the brightness adjustment, it is not doable for current firmware. I don't know whether it will be available on future version or not too.. hope so.. (may be it could help to extend the battery life a little bit longer )

Automatic brightness adjustment not working properly

Hi, i bought a macbook air 2013 in july. about 2 weeks ago i discovered the automatic brightness adjustment and checked it was working correctly. about a week ago i realized it wasnt. i turn the lights off (or cover the sensor next to the camera) and the keyboard light dims instead of increasing its intensity. and the exact opposite happens when the lights are on.
i have already restarted the system managment controller as it is explained here: http://support.apple.com/kb/HT3964 but the problem persists.
and of course i have checked the adjust keybord brightness box in the keyboard settings.
i dont now what else to do. any help would be very much appreciated.

A new Mac is in warranty for 1 year from the date of purchase.

Best.

No Brightness Adjustment, F1 & F2 No Longer Work

I'm puzzled because my PB 17" 1.67ghz display preference pane and F1 and F2 keys will no longer work to adjust the LCD screen brightness. When I purchased the laptop used, Leopard was installed and the brightness adjustment worked. To save hard disk space and run classic, I wiped the hard drive and installed Tiger (10.4) and then ran updates (10.4.11). When I boot in Leopard, the keys work, in Tiger they don't. I don't have the original restore CDs. Is there any thing that I can do to get the pb to recognize the LCD and offer brightness adjustment? Thanks.

I have a dual-boot black MacBook where F1-F2 adjusts brightness just fine in 10.5, but if I boot 10.4 pressing F1 or F2 (or fn-F1 or fn-F2) all do absolutely nothing.
Details below. I did the keyboard-firmware update in 10.5 by the way. Details below.
Does anyone have a work-around for adjusting screen brightness, even a commad-line method?
Details and steps taken: newly-arrived black macbook April 2008 with 10.5 factory installed.
1. Booted 10.5, ran all updates, including the keyboard-firmware update, fixed perms, and verified boot disk.
2. Using 10.5 disk-util, did non-destructive resize of 10.5 partition from entire drive (120gig) down to 76gig. Created 2 new partitions: tiger (50gig), and TimeMach (22gig). After reboot leopard is running find from resized partition, and I zeroed-out the other (Erase, writing zeroes in 10.5-disk-util).
3. Booted new macbook in target mode. From another black mac-book running 10.4.11 with ALL updates, ran CCC-3.1 to copy tiger to empty tiger partition on new mb.
4. Booted new mb, holding down option, and selected tiger partition. Everything works in Tiger as far as I can tell except I can't adjust brightness.)
Go figure.

[SOLVED] Broken backlight brightness adjustment on x220 after recent-

Hi.
I'm no longer able to adjust backlight brightness with hotkeys and xbacklight.
I believe issue appeared after update to linux-3.16.
Brightness adjustment keys are detected correctly in xev.
Echoing brightness value to /sys/class/backlight/intel_backlight/brightness does adjust brightness.
But xbacklight and hotkeys won't do a thing.
I already tried some magic I don't understand: acpi_backlight=vendor and acpi_osi=linux. No luck here.
Anyone else with the same issue? Are there any fixes for this?
Thanks in advance.

I saw a brief mention in the arch wiki: https://wiki.archlinux.org/index.php/Backlight
that says the kernel parameter: video.use_native_backlight=1 is now default in 3.16,
so I added video.use_native_backlight=0 to my kernel parameters and my backlight functionality is back.
awesome thx, worked for me as well. I used the -u option of efibootmgr
efibootmgr -c -d /dev/sda -p 1 -L Gentoo3.16.3-rev1 -l "\efi\boot\kernel_3.16.3-rev1.efi" -u "video.use_native_backlight=0"
