I went to a store to test out their display units. 4 out of 7 of the units I tested all made the click sound.
I thought about returning mine, but after testing the units they had in the store, the likely hood that I’d get a unit with the same issue would be pretty high. I could end up getting a unit that works perfectly at first, then begins to click weeks later just like mine did. I guess I’ll just keep what I have.
The best way to test is to close the TypeCover keyboard, and lay the Surface Pro down with the kickstand facing up towards you. Take your left hand and place it on the left side of the kickstand, and your right hand on the right side of the kickstand. Extend the kickstand all the way out to 150 degrees. As you slowly close the kickstand, it will make a clicking sound around 140 degrees. You will most likely notice it coming from the left hinge. If yours does not make that sound, then you should probably feel lucky. Mine didn’t make that sound until recently. I assume the more you use it, it will begin to make that noise.
