Charging privileges revoked

May 25, 2011



Your laptop has worked without an issue for a year, but you’ve recently had to replace your power adapter and power cord. Now you notice that the laptop powers on properly, but the battery will not charge while the laptop is powered on. When the laptop is powered off, the battery charges normally. Which of these would be the most likely cause of this issue?

A) The new power adapter does not have enough wattage to power the laptop and charge the battery at the same time

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


The answer: A) The new power adapter does not have enough wattage to power the laptop and charge the battery at the same time

Since the battery charges normally when the load of the laptop doesn’t exist, the most likely cause is the under-powered laptop power source.
