ASUS VivoBook Max randomly shuts down

[rumista]

Hi
My laptop (ASUS VivoBookMax X541N) sometimes randomly shuts down when i log in (or before logging in...or when i alredy logged in..)(It's not overheated when it does that).
But when i put it on charger, everything is fine.
It's not does that every time, but still annoying.
Can i do something to fix it?

I'm very helpless. This is my first laptop. I hope somebody have a solution.

If it only happens when you are on battery, I would say your battery isn't putting out the correct amount of power at all times and probably needs replacing.
