MacBook Pro power cord light is always orange, always 99% charged.
As of today, the power cord light is always orange, and the battery is always at 99% charged. The cord has been plugged in all day, as it always is. The light was always green before today, and the battery was almost always 100% charged. What does it indicate and how can I fix it? Thanks.
MacBook Pro 13″, macOS 10.15
