Computer stuck at 0%?

I’m not going to lie, this is my last hope for this computer. It’s been stuck at 0% for the past two days. Originally I thought I’d just not plugged it in until the last minute, but after the second day of it plugged in and not charging. I’ve gone through a few sites trying to figure it out and all of them are saying I might have to replace my battery, so this is my last hope.

Any suggestions on how to fix it without having to replace the entire battery?
