@jsf11 yes to the drawing of any amps no to holding a charge. You motherboard gets the battery state of charge through the “gas gauge” and the power management then determines the charge/don't charge. I would start with a new battery and measure the voltage on the battery connector with the charger connected. You should get something around 4-4.2V
There is a possibility that this is caused by an issue with the charging board as well as the flex that connects it to the mainboard. Check those carefully.
Remember that your battery may charge and even hold a charge but may break down under a load.
