Hi! I bought a 13" MacBook Pro that had beer spilled on the keyboard. It seems to work pretty well after being cleaned up, however I've noticed that the backlit keyboard light is almost always on, except when the overhead lighting is really, really bright. Is this normal? When I shine a flashlight into the sensor (by the iSight camera) it turns off, so I know it's working. It doesn't seem there is a "sensitivity" setting in System Preferences. I don't have much experience with unibody machines, so I'm not sure if it's normal for it to be on most of the time, or if I may be looking at a slight side-effect of the liquid damage. Thanks!
