Maybe you will be able to help me. I decided to install Windows XP and I got everything working (almost):
There are two issues though:
- I can't adjust brightness from Windows XP using Fn + F4/F5. I can use any other Fn combinations: F2, F3... but not F4/F5.
- Possibly related... I still have one Unknown Device in the Device Manager. It is a ACPI\PNP0C32\1... I do not have any idea what driver it requires... I tried looking for a driver on any other similar Dell laptops, but nothing works... :-(
Help me anyone!
I am kinda lost...
And if I hear "upgrade" advice, I will tell you that I need XP for a few applications that are too specialized and do not work well at all on Vista/7...
