This friend, hello! Here is my answer for you: About battery charging: if it is directly charged on the computer, it is fully charged when it is shut down, but when it is used, the charging state is floating, and the indicator light is on but the charged electricity is floating, so it is not charged when playing games. In addition, according to the phenomenon you expressed, your charger also has problems, please go to the professional after-sales store to test, to prevent greater losses to you. I wish you an early solution to the problem and a happy life!
