    Recently, I cannot change the brightness setting using the FN keys. I cannot increase the brightness using the keys and I can only decrease the brightness by one using the keys. Through the windows mobility center, I can change the brightness. Is there any fixes that I can do to restore this function again?

    Have you reinstalled quickset?

    Have you restarted? I had a problem once where it wouldn't work randomly and a restart fixed it; hasn't happened again recently.

    Hi, I didn't find how to pm you, so I want to ask you here. I have an XPS mostly just like your's, and so I have a problem after I upgraded my laptop to Win 8, so the problem is that i can't install couple drivers like the CardReader one, or Synaptics, can you tell me what the problem is?

    newest intel drivers for the cpu gpu, roll back your drivers and you will be fine.
