Tengo un MacBook modelo 2008 de aluminio (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 indicación de la contraseña se muestra muy débilmente en la pantalla. Muy brevemente En el caso de los ordenadores, durante una fracción de segundo, la pantalla parece encenderse antes de oscurecerse (constantemente).
He intentado cerrar y volver a abrir la tapa varias veces y cambiar el brillo, pero no ha habido suerte. La única manera que conozco de salir de esto es mantener el botón de encendido y hacer un reinicio duro.
Esto comenzó a suceder después de hacer una reinstalación limpia de OS X 10.8. Me actualicé hace muy poco desde 10.5, donde nunca me encontré con este problema.
A continuación pego el fragmento de tiempo correspondiente de mi system.log (lo que implicaba varias iteraciones de cierre y reapertura de la tapa) - no noté nada útil aquí.
