Only some PCs have the ability to charge a USB device when the PC is off. It's not something you can change if that wasn't build into the system. I suspect the 380 was manufactured before this became a handy capability.
You could put the PC to sleep rather than turning it off, and set Windows not to turn USB ports off which should allow charging. But sleep uses more power than "off"..
