Troubleshooting
What should I do if the LCD brightness of my computer screen changes?
The LCD brightness setting, adjusted with VAIO Touch Launcher, 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, follow these steps:
✍
To do the following procedure, you must have administrator rights on your 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 LCD brightness adjusted with VAIO Touch Launcher is saved and the brightness of your computer
screen remains unchanged regardless of operating conditions.
Why can't I use my touch panel?
❑ The power switch may be in the HOLD position. Slide up the power switch (in the direction of f on the switch) to release
the switch.
❑ The touch panel may be disabled.
Use VAIO Central to enable the touch panel. See Setting Up Your Computer with VAIO Central (page 117) and find
out more in its help file.
