This is what I had to do because the same thing happened to me. Go to your D: drive and select drivers. Scroll down and select VGA. Install the drivers again. It says the drivers are older than the ones installed but I installed anyway. It immediately fixed the problem. I tried recreating the problem by hitting the brightness key and now the up and down brightness key works. Let me know if this helps.

This does work. Here is the path: D:\drivers\VGA\Intel\x64\22.214.171.12417
Then just run Setup.exe.
It will give you the same information on reverting to an older driver. Just hit ok, the screen should correct itself as the driver is refreshed, and then restart to complete.

I am having this same problem. I have just had my p500 reformatted from Windows 8 to Windows 7 and both of my brightness keys dim my screen. I went to my drivers folder and saw no VGA folder. I tried the site above and downloaded the driver from that site and still no success. This is my first time posting on these forums so sorry if I have made any mistaking when making this post.

I have all of the windows 7 problems with the P500. I installed 7 x64 professional and I cannot install any drivers. I still have no LAN, WLAN, chipset drivers working. Any suggestions? I have tried many things, reinstalling windows, re-downloading drivers and reinstalling - nothing. I am pretty dissapointed.
