Battery won't charge
My macbook air battery won't charge. It always says "Power Source: Power Adapter" even when it isn't plugged in. I thought the cable was broken so I bought a new cable and power adapter earlier today. I just tried plugging it in and it won't work. There's nothing stuck in the port. I tried rebooting and I'm currently trying to do a software update. I don't know what to do. I'm a student and I really need my laptop to work.
MacBook Air 13″, macOS 10.15
