I have an Acer V5-171 manufactured in January 2013.
The problem is that though my power cable is plugged as per usual without any damage to socket, cable or adapter; power keps getting disconnected.
It seems more like a software issure rather than a hardware one, and it hasn't occured until in the past 1-2 months (I just have to unplug and replug the cord for the laptop to continue charging/running on power from the socket)
Saw someone in the archives with a V3 having a similar problem, but no solution to the problem.
It's potentially quite damaging if the system decides to starts running on battery when one is away, and thus shutting off (with the potential for loss of power).
Help greatly appreciated
