ACER ASPIRE 3 battery had died - now not charging and no power

ACER ASPIRE 3 A315-21 model

I was using my laptop and the battery symbol appeared to notify me that my battery was running low. Then it completely switched off. I plugged the charger in but no LED lights appeared and there is no power to the laptop.

I have tried a different charger but have the same issue.

I have removed the battery and replaced but again there is nothing. I have no equipment to test the battery - it is only 18 months old so surely it should be ok?

Does anyone have any other ideas? I have alot of work on there which i need :(

Thanks in advance
