My MacBook Air is randomly turning off around 70% and won’t turn on again unless I plug it in. When it turns on the battery says 0% but after 2 minutes it jumps back up to 70% and charges as normal from there. Works fine when plugged in but randomly shuts down when unplugged saying it’s out of charge when it’s not. How do I fix this?
MacBook Air 13″, macOS 15.7
