Well, I have a Asus S400CA and mine suddenly starts with this problem last night (dont know what just happened).
I have ubuntu 15.10 installed alongside windows 10 and the problem happens in both systems (energy system icon blinking and blinking...), when i plug the ac adapter the icon of battery starts blinking and saying ''battery plugged in not charging''. i've tried pushing and held the power button for more than 1 minute then released it (my finger hurted tho) then plugged the ac adapter after more than 1 minute but didnt powered up the laptop. Well... when the ac adapter is plugged with energy in the laptop but letting the laptop turned off, the orange led in the case lights up and charges the battery until 100% (when the laptop is powered off only), but when i power on the laptop.. the orange led starts blinking again, sometimes the light disappears or quickly lights up when i spin on the adapter wire then lights off again. I have my laptop since 2014 and the warranty is out now.
