The backlight that illuminates the keys on the computer's keyboard is off by default. To turn it on, press and hold the Fn key, and then tap the Z key. Press this same  Fn + Z hotkey combination to turn it off again.

You can change the settings for the keyboard backlight in Toshiba Hardware Setup: Click the Windows Start button, then click All Programs, Toshiba, Utilities, and HWSetup.

In the HWSetup app, click the Illumination tab. The Illumination properties page will appear, as shown below.

The available options are:

  • Auto - The keyboard backlight will turn on when a key is pressed. It will stay on as you type, until you stop typing for the number of seconds specified in the Backlight Lighting Time field, which you can increase or decrease to suit your preference.

  • On - The keyboard backlight stays on -- until you press Fn + Z to turn it off.

  • Off - The keyboard backlight stays off -- until you press Fn + Z to turn it on.


You must restart the computer for changes to these setting to take effect.
