I have a brand new laptop, my first with nothing but USB ports (two C, one
old-style.) Ubuntu seems to run flawlessly, and it becomes part of my
desktop setup via a single USB-C cable that carries Ethernet, video, power
and whatever connected USB peripherals require. It came with a 100W power
brick that plugs into a USB-C port.

My one disappointment is that it won't charge off anything but a
laptop-caliber charger. I'd hoped that when traveling I could bring a
single smaller phone charger and that, even if it took overnight, the
laptop could be charged. Instead it doesn't recognize anything providing
less than 30W or so.

Does anybody know if that's something I can change, either by installing or
modifying software? Any suggestions where to start researching this? If
it's not already obvious, I know next to nothing about USB.

Thanks,

PS I know there are some 30W chargers not much larger than phone chargers.
But I'd rather be able to use whatever happens to be available, either an
older charger or USB battery pack, in a pinch.

PPS It's an MSI "Prestige 14" ultrabook with 32G/1T. $1K at Costco on sale.
No touchscreen, and a lower-res screen that doesn't drain the battery on
airplanes but drives a 4K monitor at home. I like!
