The voltage on pin 20 of charger chip is missing. Resistor PR308 (10Ω/5, package 1206) is probably damaged. Check it.
If PR308 is damaged, measure the resistance to ground on pin 20 of charger chip PU301.
If resistance is low the charger chip or capacitor PC314 is also damaged. If resistance is high (in kΩ range), replace resistor PR308 and remeasure the voltages from post #3.
