Which of these would be the most likely cause of this issue?

B) The new power adapter has damaged the battery

C) The new power supply requires an OS-specific driver to regulate battery charging

D) The laptop’s charging system is incompatible with the model of power adapter

E) The power adapter is a new solar model that only works when the sun is at high noon
