Windows 10 screen brightness - VPCS11C5E

[tallvaio]

Hi, can anyone help with the screen bightness on windows 10?

I have an older model windows 7 vaio. Model number VPCS11C5E. Upgraded windows 10 a while ago and was fine. After initial upgrade i fixed brightness, but windows update has since updated and the i cant control the brighthness any more with f5 / f6.

I guess its something to do with graphics driver or light sensor driver.

Can anyone help?

Thanks
