I’m glad your battery is charging again @magician, I didn’t catch this in time on Friday but that behavior can be normal if the battery is very deeply discharged, it will initially charge at a very low rate.
The UI doesn’t know that Librem EC ramps the charge current to maximize the life of the battery. Librem EC starts and ends at a low charge rate, with higher rates in the middle. The UI is estimating 14 hours thinking that it will be at the low initial rate the entire time.
It should take about 9 hours to charge up to 100%, though again this can vary when the battery was very deeply discharged.
That’s the correct behavior. The 4-cell battery is nominally 7.6 V, so it will charge at voltages around there. You would never want to apply 19 V directly to the battery
