Same problem Precision 5530 2-in-1 with 1.4.8 bios. In my case touchpad is always working, keyboard will sometime came after 15-20 seconds. Closing and opening lid will fix problem. Also if you enter password with on screen keyboard (touchscreen) and get to gnome keyboard is working again. Ubuntu 18.04 kernel 4.18, 4.19, 4.20 and 5
