I have a Surface Book 1. The volume control button, up and down, appear stuck in the down position to where you can press neither. After disassembly, I noticed the power button had a plastic T insert in the physical motherboard control. The volume up and down connections did not have the T insert So the physical user button can not be held in place. It appears this T insert acts as a spacer of sorts to not only activate the volume control when a user presses the button, but also hold the external buttons in place so the user can press them.

Can these T inserts be replaced for the volume control?
