    Do any of the other FN keys work in XP? I have an SZ680 with XP and every function keys operates the same as it did in Vista. You can also try manually adjusting the brightness settings. Under Control Panel-->Power Options, you should have a sony power management tab. There you can set the default brightness levels for battery and ac power.
