I wiped XP off my laptop and installed Windows 7. It is beautiful!
But, I have now lost a number of adjustment settings, most importantly the ability to press Fn + Up and Down arrows to adjust brightness. It is now set at one level and does not adjust anymore. I see no other way to change brightness, not even in the BIOS.
Any ideas? I also cannot switch monitors (Fn+F8), which will become an issue when I give a presentation next week.
