HP EliteBook 8460p Display :: Brightness Cannot Be Adjusted With Function Keys
Oct 31, 2011
I'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.

I recently received a new laptop at work (a few of us have) and we are all having the same issue with this laptop. The function keys F8 and F9, which are labeled to control screen brightness, are not working. I have searched many forums and I cannot find a fix.
Product Name: HP EliteBook Folio 1040 G1
Product Number: 2CE4140876#ABA
Windows Operating System: Windows 7 Enterprise, 64-bit
The screens are so dim it's hard to see the content on them.

We have several 8460p with the same issue. They work fine until you try to connect an external monitor/TV/projector and then the trouble begins.
When using Fn+F4 to establish a dual screen output the external monitor and the built in screen switches between the two as if the PC can not determine the screen to use. On rare occasions it works but it is not reliable. I´ve first encountered this on a fair and when I tried it before the session it worked well. During the session it just started this behaviour. I took it out and replaced the graphic drivers, the BIOS and made sure the resolution was not the issue. It worked well and I returned it to the lecturing room and it started again.
I started to believe the projector was the bad part here so I did not try to use the PC again on that fair but no other computer showed any sign of trouble.
Since then, this was early this spring, I´ve seen and experienced the same problem with several computers of the same type and with different monitor and they all behave the same way.
I have spent some time now and searched the web but nothing I´ve found does explain anything around this and so far no driver update and no other update (including a full installation) has solved this.
The computer are the HP Elitebook 8460p with AMD-graphics.
There are not any other indication of that something is wrong in logs or anything.

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.

HP Elitebook 8460p will not recognise the DVD player. If I go to control panel under Device Manager, the under DVD/CD-ROM Drives it shows hp DVD A DS8A5LH and has an exclamation mark on the little icon.
If I right click and under General it shows the message "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"
I have tried unistalling and then re-installing via "Scanning for hardware changes" all to no avail. It still gives the same error. I have tried to update drivers and states that driver is up to date.

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?

HP Elitebook 8460p - is there any other way to enable the wireless on an HP laptop? I've checked the settings, bios and also made sure the wireless card installed in the laptop works. Drivers are installed correctly. When troubleshooting, it comes up with "turn on the wireless". Nothing happens when pressing the button. It stays amber.

I'm unable to find the Storage Controller Driver, link to download [URL] ....

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.

My HP elite book 8460p will not get online , but the WiFi connection shows up fine. I am aware that I am missing three drivers in the "other" devices section.. I believe those might be the reason but I'm not sure and because I can't connect the PC to internet I have to download them manually from another laptop to a flash drive but I can't find any direct downloads without getting driver set up or driver restore.. The drivers missing are, base system device, universal serial bus (usb) &, unknown device.

I recently downgraded my G710 from Windows 8 (which it came with), to Windows 7. The only issue I've noticed is that it does not display anything on screen when you use the function keys, such as the volume up or down, or bright ness up or down. The keys work, but it would be nice to see on screen that my volume is set at 2% vs say 100% when I'm turning it up or down.

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'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 much prefer to use the function keys AS FUNCTION KEYS. I don't want the default to be fast forward or rewind or stop or sound options. I want f2 to be f2 (edit excel cell) and so on. Currently I press fn EVERY time. It's annoying.
Is there a way of changing the defualt key to be what was originally intended? HP has made finding this information impossible so far.

All of them seem to work with the exception of previous track, play/pause, and next track. Is this due to me using winamp instead of wmp? I have the latest quickset software and all latest drivers from dell website.
