My phone won't turn on or charge, Stopped working

It was like 60% then it just went pitch black, wont charge, wont turn on, nothing!

I tried watching some yt videos and saw some videos that instructed me to charge the phone for 30 min, try force turning it on, holding both volume up and power button at the same time, volume down and power button at the same time, volume up and power button and plug in charger at the same time. I tried all those with no success. I had my phone for 4 years and i think it might of happened to me last year, how i fixed it was through those video steps but its not working anymore.

if it may help, I lost the original charger and am using a chromebook charger, it has the same port and it charged super fast. I left that overnight a few times and I think that might of caused it. but regardless, anything else i can try?
