Hi,

I've been trying to disable the automatic adjustment of the screen brightness but I have not managed to disable it.

I have tried the following:

1. Disabling vai the Vaio Control Center - Image Quality - Display Brightness - Turn off auto adjustment

2. Disable the windows service Sensor Monitoring Service

3. Tried to use the Power options advanced settings to disable, but there isn't the option for removing auto-adjust. I have set the power scheme to never dim the display.

After all of the above, I am still experiencing automatic adjustment of the screen's brightness. It is most evident when switching between the Metro UI start screen and various apps, but also happens when in desktop mode. 

Is anyone else experiencing this problem?

Thanks

tom
