| yep, sony vaio has function keys, but you can also set the display brightness via the power management (battery management).
You'll probalby find that the screensaver operates at different times when on battery or mains as well.
Try right clicking the desktop to change the display settings in the same area as you can change the screensaver. Somtetimes has Power management as part of the advanced setup.
To see if power management is in the startup,run "msconfig" from the Start>Run shell. |
