RE: XPS 15 9550 touchpad issue that Dell apparently can't fix
I have the exact same problem. It was working before, now I can't press the click section of the mouse pad and its not sitting flush. It's protruding about 3mil from the surface. This has to be a known mechanical issue. Mine occurred while the laptop was closed. I wonder if the LiPo is expanding when one leaves it charging. This may cause the Z height stack to go out of compliance. I've been working and designing these types of consumer products for 17 years.
