MacBook Pro won’t recognize its battery

Hi

Ive got a MacBook Pro early 2015 and I’ve never encounter any problem with it until two days ago. I was watching a movie and got a message that only had 2% battery remaining. Since I was tired I closed my laptop and let it be. The next day I put it to charge and after an hour I notice that nothing has chart and the battery wasn’t being displayed. I rubbed a diagnostic and no battery was detected. I resented the SMC about 10times and nothing changed. I turned it on and off 1000 more times and nothing has changed. Today I finally decided it to open it and unplug the battery and try and drain any power left but nothing. I can use the laptop only while plugged in. The charger has light and is working fine. Just don’t know what to do. Here is a picture of the only thing I thought it was off and I just hoped somebody could help me. Thanks
