Asus laptop battery gaming problem

[Andrei_31]

When i star a game (Fifa 16, Mafia 2), my laptop screen luminosity goes crazy and if i minimize the game and go to desktop it says battery mode and after 1 sec: plugged in and after another 1 sec: battery mode and so on. It's really annoying because the screen luminosity goes from 100% to 10% and back to 100% in a couple of seconds. I have to mentionate that this happens only when the laptop battery is charging. I'm using Windows 10.
Does anyone know how to solve this problem?

If this only happens when you are charging the battery and using the laptop, I would think you have a two fold problem.

One, you are not getting enough power to the device to do all things at once. This can happen when a cord is damaged (even if you don't see the damage) and it is not getting enough power to the device, and when the battery is being a problem as well.

And two, your backlight may be going.

my battery works fine, the laptop is new, bought 1 month ago.

If you just bought it, and it is already giving you such problems, you should contact the manufacturer. I should be under warranty and then can repair and/or replace it.
