Brightness Adjustment on New Sony VAIO / Win8

I just got a new SONY Vaio laptop with Windows 8 preinstalIed.

Adjusting the brightness has no effect on the actual screen brightness.

While the buttons and menus are working and it shows the brightness settings changing, the actual brightess doesn't change.

I reinstalled the driver and then the brightness did change accordingly, but after the computer sleeps or restarts I am experiencing the same problem.

This is a SONY VAIO Model SVF1421DCXW  

What's going on???

Hi nivkagan.  I understand that your function keys (FN) are working when you said that the buttons are working.    Do you have the correct video driver installed from our esupport website?

I experience exactly the same on the new Sony VAIO Pro. Fn+F5 and FN+F6 work after each reboot. Then after some cycles of sleep and resume, they no longer actually change the brightness despite that the on-screen brightness bar moves. I've reloaded the right video driver and made sure all settings of "auto brightness" are turned OFF. No help.

RichO, it is not the driver, but something in the BIOS or Windows system that stops working after a sleep of the laptop. I found a short sleep does not affect but putting the laptop in the sleep mode over a night will render the brightness adjustment useless.

Hi all,

 

Sorry for the delay. As for the brightness issue, please bear with us as Sony Eng is working on resolving this issue as we speak. Once they have a resolution, it will be posted at esupport.sony.com. So please check regularly.
