Frage: MacBook Air reboot after fully charged
I'm using a MacBook Air from 2015 with macOS Sierra. Every time I connect the charger to my MacBook, it charges nrmally but when fully charged (and I didn't use it for some time so that the screen becomes black) and I want to start using it again, it requests my username as well as the password from the Logon screen which only appears after a restart.
Anyone knows how to solve this?
Thanks in advance.
MacBook Air, macOS Sierra (10.12.3)
