Y battery has an x symbol and says no batteries available

Question

hi there  i have been having a lot of truble recently with my 2011 macbook pro 13 inch. I was wondering if there was anyway to solve it. I happen to have the x sumbol on my battery when i turn on my computer. I also have another question if my computer has things to connected to it via bluetooth, if i end up resetting the computer would the connecion be lost or would it still function.

Your Mac doesn't think that there's a battery installed. You could open it up and see if the cable connection has come loose. If it is connected, then the battery is simply dead and you'll need to have it replaced.
Good luck,
