Laptop turns off if power cable is removed fast or if mains shuts off (as happens a lot on the train)

Hi!

My old Asus Notebook has this odd behaviour since a few weeks that it shuts off if the power cable gets ripped out of the socket, the cabel is removed fast from the plug-in port or, if the main power vanishes (like it happens a lot during train travel). The battery itself is still fine and I'm still able to watch nearly 2 movies on a single charge so, what could be the problem here?

Laptop: ASUS UXE31, bought somewhere aroud spring 2011.

Seems like you need a new motherboard or at least have someone check the power plug if that is replaceable.
