sometimes the keyboard lights up and other times it does not? How do i turn it on?
You have to change power management settings:
1. From the Home panel, press Start (left softkey) > All Programs (left softkey) > Settings > Power Management.
2. In Adjust keypad backlight by light sensor, select whether to turn it on or off. If this is turned on, the light sensor senses the dark conditions and activates a backlight under the keypad and keyboard.
3. Press Done (left softkey).
