Проблема при выключении MacBook⁠⁠

Несколько вопросов:
1. Проблема сохраняется если мак выключается с подключенным шнуром питания и без него (на батарее)
2. Проблема сохраняется при подключенном внешнем мониторе ( если таковой есть)
3. Если все таки есть внешний монитор и экран мака закрыт, такие же помехи на внешнем мониторе?

Железячную диагностику прогоняли?
Я подразумеваю что процессор интел:

Выключаем мак
Включаем, удерживаем клавишу D до появления полосы или выбора языка
После окончания диагностики смотрим код, если есть:

Выглядит как начало конца декодера видеосигнала на матрицу.
Либо того, что на самой матрице, либо перед выходом с мат.платы.
Диагностика системы такое не определяет, тем более, проблема плавающая.
