I actually switch back to my x230 and don't have the hardware for testing, but we should really bisect this issue so the current xenial kernel can be fixed.
Anyone who wants to help can test those kernels https://wiki.ubuntu.com/Kernel/MainlineBuilds especially the late 4.4 and the early 4.5 i guess the fix came in between. Just install and reboot :)
