So my macbook charger stopped working last night. No external damage and it wasn't overheated. I used my mom's charger last night because I needed to do a paper for school. That charger worked fine and I unplugged it from my computer to return it to my mom this morning. Now neither of the chargers work. Could there be something wrong with my actual computer that is causing them not to work? I just replaced my battery and both the chargers were working fine before.
