Troubleshooting
What should I do if the brightness of the screen changes?
The brightness of your screen when adjusted with the Fn+F5/F6 keys is temporary and this adjustment is overridden by the
setting on the VAIO Power Management tab when another power scheme is selected.
To save this preference for the brightness
To do the following procedure, you must have administrator rights on the computer.
1 Click Start and then Control Panel.
2 Click Performance and Maintenance.
3 Click Power Options.
4 Select the tab for power scheme settings.
5 Select the desired power scheme from the drop-down list.
6 On the VAIO Power Management tab, select No change for LCD Brightness.
7 Click OK.
The preference for the brightness adjusted with the Fn+F5/F6 keys is saved and your screen brightness remains unchanged
regardless of operating conditions.
