MyToshiba laptop won't turn on!! please help

Hello,
My toshiba laptop ran out of battery and it went down to 2% and told me to plug in my charger although it was already inside and was supposed to be functioning properly. Afterwards, it went down to 1% and the same message popped up saying that I was supposed to plug in my charger. I checked over and over again and it seemed to be fine so I ignored it. I tried changing my charger with my other one to see if it worked and when I pulled it out, my laptop just went black and wouldn't turn on again. When I put my other charger in, it still wouldn't turn on and the charging symbol down below my keyboard started flashing yellow. Please help!!~~ It won't turn on again
