Check to see how long you have your Auto Backlight Dimmer Timeout set for. You probably have the default setting for 30 seconds. Look under Menu, Options, Screen/Keyboard, Backlight Timeout. You will also see Automatically Dim Backlight. It will use more battery power to keep your backlight on for longer, but it is all a trade off!!! Hope this helps!!!
