Function keys - F2 and F3 not working.

[Kushashwa]

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. 

Please help me out with this issue.

Hello and welcome to the HP Forums.

I would first make sure that the Intel Grpahics driver is a version that is HP supported.

Intel Graphics Driver:

If the issue still percists then attempt to reinstall the HP Wireless Button driver as it assists in controlling the function keys on the notebook.

Let us know how how this works for you.

Thanks,

Have you tried to check the power options in the Control Panel?

You will find a screen brightness slider at the Bottom of the page for Power Options.

In Windows 8 you can find Windows Power options by pressing Windows+Q buttons together to bring up the search bar and type Power in there.
