Vaio Power Management Utility on Windows XP and Vaio VGN-FZ11M

[insmac]

Hi there,

I've been using VGN-FZ11M for a couple of months and I want to downgrade OS to Windows XP Pro. Two questions remain:

1) Is there a version of Vaio Power Management Utility compatible with XP and FZ-11M?
2) The same problem with function keys.

Is there someone who uses XP on that model?

Any help appreciated,

Regards,
