I have old Dell Inspiron 9300 laptop. It had windows xp sp3 and I upgraded it to windows 8 Pro. After upgrading I noticed the brightness icon on the settings had unavailable written on it. I am unable to change the brightness setting. When I point the mouse on top of the brightness icon, it reads Windows cannot adjust the brightness on this display. Also the functions keys on the keyboard for brightness don't work. Is the problem with my Quickset Driver ?
I would really appreciate if somebody can help me with this issue. Other than this issue the laptop is working fine. The audio is working.
It seems to be an issue with the Quickset application. This system has not been tested with Windows 8. The drivers will not be available for this system. You can refer to the link for a compatible system tested by Dell with Windows 8 http://dell.to/RnDAFu
You may try to install the Quickset in Compatibility mode. It might work.
Please reply in case you have further questions.
