Okey, I own this Device and I encountered this issue after BIOS Updates. the power cuts form the ports nor USB or Type-c Port will work. Fix: the first method was downloading an older BIOS version and update it to that. it has worked. but... after few weeks the problem appeared again. The Second method was to unplug the laptop from the power or any other cables. power off the computer then hold the Power button for more than 30-60 seconds. then press the power button one time and congrats the ports are usually working again. Hope this works for you..
