      Hello, few days ago I downloaded Windows 8.1 full version from my DreamSpark Account and I installed it on my notebook. Windows automatically downloaded all required drivers including Intel HD 4000 Graphics Driver:

      But I have a big problem: I can't change display brightness on charms -> settings / control panel and power managament. This is a const and I can't change this.. my question is why and what can I do this? I tried re-install Windows and install other driver but I got the message that installed a newer version of the driver:

      Who has a same problem?

      Another problem is not moving the computer into sleep mode after a certain time, for example after 10 minutes. My screen goes blank but nothing else. My friend has the same problem. Who can talk me how can I fix this?

      My notebook model is: Dell XPS 15 l521x
