What should I do if the brightness of the screen changes?

The brightness of your screen when adjusted with the Brightness button and 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.

1Click Start and then Control Panel.

2Click Performance and Maintenance.

3Click Power Options.

4On the Power Schemes tab, select the desired power scheme from the Power schemes list.

5On the VAIO Power Management tab, select No change under Plugged in and Running on batteries for LCD Brightness.

6Click OK.

The preference for the brightness adjusted with the Brightness button or the Fn+F5/F6 keys is saved and your screen brightness remains unchanged regardless of operating conditions.

What should I do if the external display (or TV) does not display anything?

If you change the log-on user with the Fast User Switching function after your computer started, you will not be able to select a display by pressing the Fn+F7 keys.
