Hello everyone, my macbook pro goes to sleep with 40% battery left. When I try to turn it back on, it tells me to charge it. This has been happening for sometime. I know that the condition of the battery is "Service Battery". I think this might be an issue related to that. I tried SMC reset but it still happens. I'll put my coconut battery info, maybe that will help. I have a battery that I purchased a while ago; should I try to replace the battery if that's the only way to solve this problem? Thanks.
