It's been only 5 months since I bought this Asus X441N. On its 3rd month, it automatically shutdown even if it is not yet 1 minute turned on. Prior to this, i usually had charged my laptop at 10%. So when this had occurred I charge it at 50% or even stay it just plugged in. The automatic shutting down state decreased for atleast 1 month, as i have observed. Yet just today, It doesn't longer turned on unless plugged in. What should I do ? Thank you
