I have installed windows 7 on my Sony VAIO SR220J/B and i do not think that anything is wrong with this system except for the Fn+F5/F6 brightness controls. I am using Alps and Synaptics drivers on this system and it has an Upek fingerprint software. Fn keys are working but i guess Fn+F5/F6 has something wrong as it is not changing the brightness of my screen.
