Acer Travelmate X349 not starting

Hi all tech gurus

Tried switching on this laptop and the keyboard lights up and it turns off after 10 seconds. Repeated this and it just does the same thing. The battery was charged fully as I used it earlier. Also when I plug the charger in, it switches on and off on and off by itself. In both cases nothing happens on the screen. It does light up but nothing happens within the 10 seconds. The laptop is brand new, not even a month old.

Please could someone out there give me some help. Thanks in advance.
