There are no XP utilities for my model, I've tried to install utilities for other modeln on my notebook, but it is not efficient. Brightness change still not working. What can I try else to do them work?

Hi knik777,

have you tried using this Windows XP Downgrade link ..

[knik777]

yes. tried. this link goes to ftp://ftp.vaio-link.com where there are NO UTILITIES for my model, there are only drivers. So as said above i thied to install utilities from other models. and it is no result.
today i thied to install utilites from sony-asia-site. But there is only CR13 and CR23 models. And NO CR22 model! these downloaded utilites bring no effect too. Only slidebar comes to screen when try to push Fn+F5(F6) buttons. And there is no REAL brightness changing!
