F1 & F2 Keys + Brightness controls not working

I just came home with my Brand new Macbook Pro 17" i7 and as soon as I try to control the brightness with either F1/F2 or the slider in Preferences nothing happens???? Do i have to take the computer back to the store again??

Lasse
If the F1 and F2 keys are not working you should take it back, perhaps it's a hardware issue. I know it is a pain to take it back, but that's what I would do. I would also try the MBP in the store before leaving.

Brightness Control not working after Windows 8 install...

Hi All,
I have a late year 2010 MBA core2duo with 4GB of ram, and I was running Windows 7 for a long time and recently bought a Windows 8 upgrade key. I heard the boot camp drivers were updated so I decided to load it up. I installed the new boot camp drivers on the Windows 7 side before the upgrade (had to use the command line to do the driver upgrade).
Windows 8 is all installed and the only issue I have is the brightness control doesnt work at all. I disabled the adaptive brightness as a lot of threads have been saying. Anybody have any ideas what I need to do to fix this?? It seems to be stuck on BRIGHT.

I have been having the issue of no brighness control when running windows through bootcamp for about 6 months now and have not found any applicable solution online.
While messing around trying to figure it out yet again I noticed that my monitor driver was signed by team viewer...
Sure enough clicking the roll driver back button resolved the issue by rolling the driver back to the Microsoft driver...
So long story short:
Right click "My Computer" click properties
Click device manager (lop left of window)
Expand Monitors section
Double Click monitor
Click driver tab
If the driver here is not signed by Microsot or Apple click the roll back button. My driver version is 6.1.7600.16385 (Driver date 6/21/2006)
Rolling this back instantly resolved my issue. I will now propagate this post to all the threads I saw regarding this issue.
I am running windows 7 x64 Ulti on a 15" rMBP.

Thanks

Hi there , Thank you for visiting the HP Support Forums and Welcome! This is a great site to get answers and ask questions.

Brightness control not working in Windows 8 x64 after sleep with Boot Camp 5.0.2

Hi,
I am using Boot Camp 5.0.2 with Windows 8 x64.
Wheen the computer has been in sleep mode, and wakes up again, the brightness control won't work as expected.
Usually the screen is to dark (darker than before, what it should be), and after some time pops up brighter as it should be.
Has onyone else seen this issue?
I mean, it seems that for brightness we use the internal control GUI of Windows 8, and not the Apple one that is used in Windows 7 and in Windows 8 for the sound control.
Macbook Pro 13" Retina, early 2013 (brand new) with 8GB RAM and 512GB SSD and 3.0GHz i7.

Brightness control not working after sleep

Sometimes, after I close the lid for some time and then open the lid again (putting the computer to sleep?) the screen is very dim and the brightness controls don't work. Solution seems to be rebooting the computer. Apparently this problem has been around for a long time:
2009 https://discussions.apple.com/thread/1147601?start=0&tstart=0
2007 https://discussions.apple.com/thread/1119174?start=0&tstart=0
I'm on a (nearly) brand new five-thousand dollar MacBook Pro with the latest OS (Lion?) with all the software and firmware updates, and the laptop has been rebuilt twice by the genius bar at the Apple store due to a faulty solid state disk drive and a subsequent disk corruption issue. And, let me just throw in for any Apple engineers who might be listening, that if I close the lid (sleep?) when my laptop is fully charged, it will be dead, or nearly dead by the next day. I've got an $800 two year old Asus that I closed the lid on and came back to weeks later and it still had nearly a full charge (I opened it up and went right on working for a couple of hours). Very disappointing for a $5,000 computer! But I digress...
I'm sure the battery situation is hopeless, but is there any hope for a resolution to the brightness control?
And let me just say that I very much appreciate all the hard work and helpfullness of the good folks at the Apple store and on this forum. It's not your fault this $5,000 machine has such aggrivating shortcomings. It's like buying a Ferarri (yes, I admit...it's a Ferarri) with a door that won't open and windshield wipers that don't work. And you know what's worse is those TV commercials where the Mac's are smugly portrayed as such superior machines...OK, sorry...I'll stop.
Off to reboot so I can see the screen...any help would be appreciated.

Software Brightness Controls Not Working (Dell D630)

I've just encountered a problem with my software brightness controls on a fresh install of Archlinux (using KDE as the desktop environment). I can adjust my display's brightness to my heart's content using the brightness keys on my keyboard, but none of the stuff in KDE power management works. In addition, I've also tried the xbacklight program without success. It doesn't give me any errors, it just fails to adjust the backlight at all. Any ideas why this is happening and what I might be able to do to fix it?
Thanks!

Moving to Laptop issues...
There are quite a few threads about backlight issues with the 3.13.x. kernels.

Macbook Pro Brightness Controls Not Working

Ok, this is really weird. I have a Macbook Pro and after installing the new aluminum keyboard with the Keyboard 1.2 update my brightness controls in OSX no longer work. The weird part is if I go into Windows via Boot Camp my brightness controls (F1,F2) work fine. In Display Properties in OSX there is no brightness slider.
Can anyone help? Thank you.

"I just tried this. Go into System Preferences -> Display. Turn off Automatically adjust brightness as ambient light changes. Now move the Brightness slider right and left, left and right. Turn on Automatically adjust brightness as ambient light changes. When I changed it from far left to right then left again it was ok."
Hey, thanks for the tip Neil. I was trying to figure out why my computer would dim and then get brighter. It would keep changing after every little thing i'd do. Honestly, it was freakin annoying.

L430 Brightness controls not working FN-(F8/F9)

Hi folks,
I have a problem that can't resolve and hopefully you experts could assist on this issues.
My new L430 has an fn key option (fn-f8/f9) to adjust the screen brightness and it doesn't work as intended. I tried reloading the hotkey features integration and it doesn't help as well.
Anyone could have an idea on what's go wrong? Please kindly advise.

(fn+F2 and fn+F3) for brightness are not working

(fn+F2 and fn+F3) for brightness are not working, while the other function working properly... help me plz
DJanoon

What is the product number?
Did anything change before this started happening?
Power the system on and press F10 about once a second to get into BIOS. Once you are in BIOS, go to the configuration tab (typically next to last tab) and set Action Keys to enabled. Save the changes, exit, and the system should reboot automatically. Test the brightness keys wihtout pressing the Fn key. I suspect they will not work in this state, but I want to rule out the possibilities while awaiting the product number.

It was working before two days. I didn't install or update any display driver and driver from toshiba download site is installed from the day first. display-20130111074851.zip

Hi Chand
This is user-to-user forum and we can try to help you with useful tips.
You cannot expect that someone collect and send you drivers. How to send you, for instance, display driver with 100 MB capacity.
You must download it alone. I presume you have machine designed for Middle East so visit please Toshiba support page on http://www.toshibamea.com/ choose your destination and check for support. As far as I know Toshiba offers drivers for supported operating systems.
Instructions about Win8.1 upgrade you can read on http://www.toshiba.eu/innovation/generic/windows8_1-message/
By the way: have you upgraded Win8 that you got to Win8.1? Im not 100% sure but I presume you got machine with Win8 64bit version, right?
Have you created recovery media before you have installed Win8.1 version? If not please do this. Recovery media creation is very important.

Appended Key figure is not working in Delta reverse record

Dear All,
I have enhanced 2LIS_11_VASCL datasource, to pull value from condition record, called Surchage.
I have set reversal indicator for this field in my datasource. I have written code in CMOD to get this value from KONV table of that sales order.
Now when value is changed, delta record for this, automatically creates reversal record, but it shows new value of surcharge as negative, because that code is pulling value which currently exists in table.
For example for order 350089 , if surchage is $ 100 . User changes it to $200
Then I get following record.
Reversal Record - $200 (This should be instead -$100 , i.e. previous value)
New Record - $100.
Because of this my new value is not getting updated in table.
I can't use overwrite mode in ODS because some other technical reason.
How can I solve this problem?
appended Key figure is not working in Delta reverse record

LIS have before-after delta. So ODS should be in Overwrite mode. If that is not possible.. try sorting the records in Start Routine such way that the - 100 $ is above the - 200 $ records in Data Package.
but this is risky as it will affect other key figures for which things maybe fine. I guess you need take Data Package records in an internal table. And then sort this internal table. then you can read the internal table in update routine of this key figure.
OR (If you are on BI 7.0) you introduce an InfoSource in between DS and DSO with Overwrite mode for this Key Figure.

Resetting may help. Hold the on/off and home buttons together for about 10 seconds till the Apple logo appears.
You only want to do this if your iPhone won't turn on or off and is completely frozen. Instead, try Resetting all settings in Settings > General > Reset > Reset all Settings
I completely disagree. Reset All Settings (your suggestion) would reset the OP's preferences and settings. By contrast, resetting the iPhone (as I suggest) changes no preferences, settings, or any other data. It simply starts the iPhone over, with no data loss.
