Thanks Anton9121 !!!
It worked perfect for Vaio VPCCW1

Anton, thanks for the solution.
However on reboot it doesn't remember the brightness level what I set earlier and on first brightness '-' operation it goes to 0 from maximum. How can I overcome this?

Thanks.

Hi Anton,

Few years down the lone now, ran through all of the steps on a VPCCW16FG Vaio but didn't help adjust screen brightness. Keys are fn+F5+F6. Bar moves but no action.

Any new update on this would be kindly appreciated.
Regards
