Madasafish, you're running a hybrid, that might be why it freaked out. the operating system may include parts from another device which controlled the backlight. It may have tried to call up something that doesn't exist and got stuck. It might have claimed you passed because there were no error messages to the system from the item that didn't exist in the first place.
This may be one of those utilities that can be used for most of the device, but not some parts when using a hybrid. battery pull was a good call
Have you ever wondered why things intended to make our lives simpler keep getting more complicated to use?
