Having problems with your Sony VAIO® VGN-FZ190N3 PC Notebook ?

Bright Adjust! I downgraded my VGN-FZ190N from Vista to XP Pro SP3, everything seems normal except that i can not adjust the brightness of the LCD by the combination of Fn + F5/F6 (the function key Fn work normal). The graphic board is NVIDIA Geforce 8400M GT. Give me your idea about this. Thanks in advance.
