Once the battery is safely removed, plug the charging cord into the charging port on the side and plug the other end into the wall.

DO NOT turn the computer on or touch any of the internal components during this step.

If the light is on after plugging it in, you have just confirmed that something is wrong with the battery, which means you're on the right track!

If the light on the side blinks upon plugging it in, the battery is not the problem. If that is the case, put your laptop back together and consult an expert.

Unplug the charging cable.
