Introduction
The power and volume buttons are responsible for turning your tablet on or changing the volume of your tablet. If the tablet doesn't respond to pressing any of those buttons, it is likely that the buttons are jammed or worn out from use. In order to resolve such issues, you'll have to replace the strip that holds the power and volume buttons. This guide shows you how to replace that strip.
