Charging ports and connectors hardware issues

Check the battery health report and compare the original capacity of the battery (design capacity) and the current (full charge capacity).

A big drop is an indication that it is time to replace one. In case your computer only works when connected to electricity, your battery is drained. In case it will not even start, the charger or charging port can be defective.
