Why does the LCD brightness change automatically?
The LCD brightness of your computer screen changes automatically according to ambient light intensity that is measured by
the ambient light sensor. To disable the automatic brightness settings, follow these steps:
1 Click Start, All Programs, and VAIO Control Center.
2 Click Display and Automatic Brightness Settings.
3 Click to cancel the Adjust brightness automatically check box.
4 Click OK.
Why does the LCD brightness fluctuate when I change it or place my computer back into
Normal mode from Sleep mode?
This may occur on models with the LED backlight when the LCD colors are calibrated and does not indicate a malfunction.
What should I do if the external display remains blank?
Press the Fn+F7 keys to change the display output. See Combinations and Functions with the Fn Key (page 35) for more
information.
