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

✍

To do the following procedure, you must have administrator rights on your computer.

1Click Start and then Control Panel.

2Click Performance and Maintenance.

3Click Power Options.

4Select the tab for power scheme settings.

5Select the desired power scheme from the drop-down list.

6On the VAIO Power Management tab, select No change for LCD Brightness.

7Click 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 114) and find out more in its help file.
