MacBook Pro 13 Battery Isn't Detected-Help!!!

[Sherina]

I don't know what's going on. But I turned on my laptop today and it was running off the battery when I noticed that the battery meter on the menu bar didn't display my battery information and when I hovered over it said it was still calculating the battery. So I restarted the computer and it then had an "x" on the battery saying it wasn't installed. I don't know what to do because I'm using the MacBook with an internal battery and I'm not sure if I can unplug the battery and put it back in or what.

Try resetting the SMC
