In my particular case, my ac adapter is good and I have 20.2vdc at JDCIN1 (motherboard connector for dc input). However, I do not show that 20.2 volts at JBAT1 (motherboard connector to battery). Anyone have experience with troubleshooting between these two points?

Thank you for the response @jayeff . It turned out to be a connection issue and once the battery had a good connection, it did start to charge again. Again, thank you for the response and it is nice to have this forum where we can go for advice! I guess I did not realize that their battery management was sophisticated enough to completely stop all charge current in a situation like that.
