Yoga Laptop (ThinkPad) - Machine Type 20C0, Model S15F00
My USB ports and touch screeen are not working and there is a yellow exlamation on the USB Root Hub emblem under device manager. I attempted updating driver but says it's unable to find device update information. USB ports still provide power but do not communicate. Screen will work with stylus/pen but will not respond to touch. I am interning in Switzerland and unfortunately do not have access to warranty providers here, so any help would be greatly appreciated.
