My brightness function keys are not working. Other function keys like music player, mute etc are working fine in my windows 7 os. My Model no is 15-r006TU. I have installed all display drivers and checked action key settings in my BIOS settings. Nothing works.
View 3 RepliesI'm having the same trouble with my brand new 8460p : the brightness of the display can not be adjusted with the function keys (fn+F-keys) while in Windows. In other threads the problem has been solved by installing newest chipset drivers (which was not provided by HP), but in these threads the computer has been an earlier model. 8460p has the new QM67 express chipset and currently I'm running the latest drivers (according to intel's detection web site) for it.
I'm running a fresh install of Windows 7 Enterprise 64bit with all the latest drivers.
Suddenly I can't change my screen brightness with f2 and f3, and neither in control panel. Is there a new driver I need to install ? My product number is > G6S71UA#ABA

The Brightness funtion Key is not working. But other function keys are working Properly...
I have had my laptop for a couple of weeks. I am no longer able to change the brightness with f2/f3 as well as from battery settings.
Model:HP ENVY 15t-u000 x360 CTO Convertible PC
I am using a HP ProBook 450 G2 with Windows 7 Enterprise (64-bit).
None of the Fn + Function keys work (i.e. for battery, brightness , sound).
Is there any actual driver for this?
I purchased HP Pavilion 15-n209TX Laptop this year and the functions keys were working properly. But, later on from 10th of May 2014, they are not working! I checked whether there was a software due to which it was happening, but, I didn't install any kind of software which can harm the functioning of the keys. I am really struggling with very low brightness. The latest thing I did was - windows update - which installed the following softwares
Microsoft Silverlight
Also, I installed HP Quick fix.
Whenever I press F2 or F3, it just shows the slidebar (it doesn't go up and down though) and when I click on the top of the slidebar, nothing happens again. I also tried to go to the brightness option in the Windows Mobility Centre and tried to adjust the brightness - but nothing is happening.
I recently formatted my laptop to windows 7 ultimate and since then can not get my function keys to work. I've reinstalled drivers that I thought might work and nothing.
When I could no longer adjust my brightness is when I noticed that my function keys were not working. Is there any other way to adjust the brightness on my laptop besides the function keys? If so I have not figured it out.
I m having an HP pavilion G62016-TX with Windows7 ultimate with 64 bit version,Purchased on Nov'2012.
Recently my PC crashed and when it was reinstalled with all drivers from HP FTP i am having below problems.
When i am adjusting my brightness , it is getting adjusted but the adjusting bar usually shown in the screen is missing.
When i am adjusting my sound , it is getting adjusted but the adjusting bar usually shown in the screen is missing.
Since my laptop (dv6 pavilion 7090el) had to be formatted to another copy of windows 7 (64bit), i can't manage to make hotkeys for brightness(f2-f3)/volume(f9-f10).
I tried to install/uninstall/install HP quick launch software (with all the system restarting combos possible) and the software doesn't really seem to be installed, since it only appears in the Control panel but not anywhere else.
The BIOS "action key" option in System configuration is already "enabled" ....
The brightness control keys (f2 & f3) on my pavilion dm4 stopped working all of a sudden. I'm operating windows 7 64bit. I've tried reverting to previous system restore points. I've also installed the BIOS, Intel chipset, and graphics drivers. All the other function keys are working properly, just can't change the brightness. Right now it's stuck on the brightest setting. I'm getting terrible eye strain from the screen.

I have a 3-yr old Thinkpad T500 laptop w/ XP. My on-screen volume and brightness displays have recently disappeared. Spoke with customer support and was advised to download all the machine updates....did that, but still not working.
View 9 Replies View RelatedI've got 2 separate but really annoying issues with my W540 20BH:
- display brightness keys not working: when waking up from Hibernation mode, sometimer (really, randomly!) the display brightness keys (Fn+F5/F6) don't work.... either if the display brightness is stuck on max, min or an intermediate level...Is there a way to shut down and restart the process which commands the Fn keys?
- audio channel commutation gets stuck. Normal behaviour of the audio configuration is:
1) speaker volume disabled, mic disabled
2) when plugging in a 4-pin headset, headset's volume is on, headset's mic is switched on; speaker volume is still disables.
3) when unplugging the headset, speakers' volume is still 0
After each boot, the audio channel is at 0, but doesn't commute to the headset when plugged in! I have to open Configuration Panel, realtek properties. With this window open, unplug and re-plug the headset. Now, the volume has its normal behaviour.
Any better way to configure audio channels and evenments, which is able to bypass realtek's manager?
I can't adjust screen brightness using either function key or in control panel. Using the function key the little panel of brightness volume shows up on the screen but does nothing. And in control panel, through either the bottom brightness scroll or the power option won't change anything. Only time when the brightness will change is I unplug the power, but in the power settings it won't let me change/adjust the brightness.
And what is the battery function key for? I press it and it does nothing. XPS L521x
I have XPS 15 (L501x) laptop. I cant adjust the brightness of my screen through the function keys(quick set) or from Control panel (Control PanelAll Control Panel ItemsPower Options)I have already tried
Reinstalling quick set
Restoring
Reinstall Drivers from my Drivers CD
Chipset : Intel HM57
Video drivers : Intel HD graphics
I also tried to install bios drives, but the system would allow me, saying, its already the latest
I have installed the latest driers and since then I am unable to change the screen brightness using function keys. I have installed multiple driver updates hence it is difficult to find out which driver is causing the issue.
View 3 Replies View RelatedI open this post to report a brightness problem on Lenovo Z500 Ideapad. Yesterday I've upgraded to OS Windows 8.1 and when I adjusted the screen brightness it goes off, and brightness adjust function doesn't works. I've solved my problem reinstalling the Intel video drivers, downloaded from Lenovo Driver Support.
It seems that Windows 8.1 upgrade disables video drivers.
I cannot adjust the brightness of my display using the Fn keys or the Control Panel... I have already had to replace my battery once... I need to be able to adjust the brightness in order save my battery life!

The brightness on my display is somewhat dim. How do you increase the brightness?
View 3 Replies View RelatedI've recently bought an HP Probook430 and installed Windows 7 Ultimate 32bit and I don't seem to be able to change the display brightness, using the fn button+f9/f10 (although volume settings are changed in the same method smoothly).
Although the brightness settings don't seem to change, this bar does appear when pressing fn+f9/f10. What should I do in order to make the display brightness settings changable?
I recently had to reinstall windows on my XPS 15 (l521x) and i now have the F-keys working with their assaigned function (Brightness, play/pause, volume, etc) however, the graphic overlays no longer appear.
For example - Fn + Brightness^ - will increase brightness but with no graphic showing what the current brightness level is.
Any way to get this useful feature back?
My 3.3 year old HDX 16T-1000 CTO Premium Notebook PC's display no longer functions. Upon cold boot, the display nearly always comes on but flickers at about 1/2 brightness. If I twist the display, sometimes I can get it to come on at full brightness. Upon letting go though, the display goes black. The only way I can get it to turn back on is to put the notebook to sleep and then wake it up. The display comes back on for about 2 seconds (mostly at 1/2 brightness) and then goes black again.
I do get a normal display when I connect to an HDTV via the HDMI output. HP's techs had me download and reinstall the chipset, NIVIDIA video driver and BIOS software. This made no difference whatsoever.
Since I can get the display to turn on intermittently, could the problem be just a worn video cable or something more serious?
recently i have bought Hp-r006tu laptop.In which Dos is present only . i want to install windows 8 but its saying ACPI_BIOS error. I have downloaded the drivers jst now. i want to update through pendrive . can it be possible?
