MacBook is charging but won't turn on, no chime either

Hi team!

I've been having the bad habit of not turning off my macbook and I think this has finally caught up with me.

Yesterday the macbook wouldn't turn on at all. It is charging though, and the macsafe color changes when performing a smc reset.

I've tried all sorts of Smc reset, pram, not of that worked. Actually the first time I did the Smc reset, the fan went on, my phone that was plug on the USB started to charge as well, at that time I was confident I could get it to switch on, but nothing happened. Ever since all my efforts have been useless, not a chime, fan hasn't starting to run ever again.

I opened it and unplugged the battery connector and back on but nothing….
