You need to use the Toshiba "Power Saver" console. Go to Control Panel -> TOSHIBA power saver. Click the Icon and use the console to adjust the brightness for the various power schemes. If you don't see the TOSHIBA power saver icon, go to Go to Control Panel ->Power Options and open that console. Select "TOSHIBA Power Saver" option in the "Power schemes" dialog box.
