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.
1
Click Start and then Control Panel.
2
Click Performance and Maintenance.
3
Click Power Options.
4
On the Power Schemes tab, select the desired power scheme from the Power schemes list.
5
On the VAIO Power Management tab, select No change under Plugged in and Running on batteries for LCD Brightness.
6
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.
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.
