Slowly charging. Yes I looked for this

I've searched and searched, and no one seems to have a good answer. I already replaced the charger port. Is the new part faulty? Kinda goes against reason that the initial one failed, and so did the new one. But it charges slowly/won't charge. I'm trying the disconnect battery, reconnect, remove display cables and plug in charger method right now. I could easily see this being a software issue. However not only am I locked out of the customers device, it's all in Spanish. Wanna get this figured out, anybody?
