Ubook pro n4100 battery issue

my ubook pro N4100 was working fine, battery was lasting well enough and all was well. Yesterday i unplugged it and was going to move where i was using it and it died as soon as i unplugged it. Now it seems as though there is no battery present, or functioning. Is there anything i can do to fix this? I’m frustrated because its not that old of a device and now i have to keep it plugged in or it dies all together.

You can check if battery is present in the device manager. If yes- probably battery is dead.
If no- you can check connection on motherboard, but probably after this you will lose warranty.
