The USB 3 ports stopped working on this 2-in-1 and I sent it in for repair. They replaced the hard drive and reloaded Windows 10 and sent it back. After "completing" the install of Windows 10, the USB 3 ports still do not work. They do not recognized any flash drive nor a mouse receiver. The USB 2 port functions fine. (The flash drives do get very hot when plugged in even for a short time.)
I guess the diagnostic software that is relied on that says the USB ports are OK isn't testing everything.
