screws spin but dont come out
the 2 screws on the back panel closest to the center front on my lenovo yoga 2 13 spin, but they don’t come out and keep the back panel locked in place. they have a tiny bit of resistance and feel like they step 12 times per revolution. could the standoffs have broken off allowing the screw to spin but preventing it from unscrewing? do i have to cut the panel open?
