What causes a Macbook to ignore the charger? I have verified that my charger is working, and when the failures occur I have verified that all cables are securely connected. It just seems as if the machine just arbitrarily decides not to charge.

You may have Optimized Battery Charging set to ON on your MacBook Pro.
Optimized Battery Charging: This feature helps to reduce the wear on your battery and improve its lifespan by learning your daily charging routine. It delays charging the battery past 80% when it predicts that you’ll be plugged in for an extended period of time, and aims to charge the battery before you unplug. You can change this option in Battery preferences.
