If it is that new and already giving you problems, you need to contact either the place you got it from or the manufacturer and get them to give you a new one. No new device should give you any issues.
I also have the same problem. Mine is same model(X541S). This is first time I bought Asus device. Previously I used Dell and Acer lap tops and never had this problem. I even contacted service provider in my country and they couldnt fix the problem. Asus doesnt take any responsibility. I decided to sell it for half price. This brqnd is a real garbage!
i had the same case but after few days i realized that it's a battery's security.. so if you want to work with battery only without plugging any charger you need to shutdown your device and start it without plugging charger.
