Macbook wont turn on for a few days then turns on
Hello! lately my MacBook won't turn on for a few days. Then all of a sudden it turns on again and works. This has happened 2 times within the past 2ish weeks. Currently typing on the MacBook Pro that is now working. Would love to learn what is causing this. Im thinking it needs a new battery but want to know if anyone actually knows what's up with it.
Thank you!
