From time to time, the owners of MacBook Pro and MacBook Air complain about a problem related to the fact that a cross appears in the battery icon in the top macOS menu, and when you call the battery menu, the system reports the absence of it.

All this is usually accompanied by a loud roar of the fan and the slowdown of the laptop. Previously, it was assumed that to solve this problem it is necessary to deliver the car to a service center.
