Solved! Is this a battery problem or a computer/driver problem?

I bought a new GDP Pocket mini PC 6 months ago; this is a great WIN10 laptop for traveling (7'' screen; ultra small; with full keyboard) -- BUT NOW IT DIED!

Specifically, all of the sudden the battery no longer holds a charge for longer than 4 minutes (used to be 5 hours under worst circumstances). I ran the powercfg battery report and it seems the battery suddenly is measured to hold only a tiny charge (after 9:08 AM on 2018-04-09). Is this a battery problem or a driver problem? What else to try? Note that the battery cannot be replaced (cannot even find it on the internet).

My powercfg report looks like this:

Solution
Not a driver problem, more likely a battery failure or problem with the circuit board that delivers power to the battery (but I'm leaning towards the former, based on your description of the problem).

Thanks; I also think (hope) it's the battery -- just found one for sale at a place in Florida. Now just need to figure out how to replace the battery. there seem to be a number of tear-down Youtube videos available. Don't have much to lose at this point.

Thanks!
