Tengo un modelo de aluminio para MacBook a finales de 2008 (5,1). De vez en cuando, después de volver a abrir la tapa de mi MacBook, la pantalla no se ilumina. Con esfuerzo puedo ver que la solicitud de contraseña en realidad se muestra muy débilmente en la pantalla. Muy brevemente , durante una fracción de segundo, la pantalla parece parpadear antes de apagarse (de manera consistente).
Intenté cerrar y volver a abrir la tapa varias veces y cambiar el brillo, pero no tuve suerte. La única forma que conozco de salir de esto es mantener presionado el botón de encendido y hacer un reinicio completo.
Esto comenzó a suceder después de hacer una reinstalación limpia de OS X 10.8. Actualicé recientemente desde la versión 10.5, donde nunca encontré este problema.
Estoy pegando debajo del intervalo de tiempo relevante de mi system.log (que involucró varias iteraciones de cierre / reapertura de la tapa): no noté nada útil aquí.
