I have an Inspiron 710m laptop, and there is a button that is able to be pushed down to the right of the power button by about 3 inches (if you are holding the laptop normally on your lap, it is to the right by 3 inches). This button causes the screen to go off when normally pushed down by the screen of the laptop when pushed to the close position. Right now, this button is stuck in the down position. My computer still works, but this function no longer works as the button is stuck in the down position. Any change anyone knows how to fix this? Help is extremely appreciated. Thanks
