Layar MacBook sangat gelap setelah dilanjutkan pada OS X 10.8

2

Saya memiliki model aluminium MacBook akhir 2008 (5,1). Kadang-kadang, setelah membuka kembali tutup MacBook saya, layar tidak menyala. Dengan susah payah saya dapat melihat bahwa prompt kata sandi sebenarnya diberikan sangat samar di layar. Secara singkat , untuk sepersekian detik, layar tampaknya menyala sebelum menjadi gelap (secara konsisten).

Saya mencoba menutup dan membuka kembali tutupnya beberapa kali dan mengubah kecerahan, tetapi tidak berhasil. Satu-satunya cara saya tahu untuk keluar dari ini adalah dengan menahan tombol power dan melakukan reboot keras.

Ini mulai terjadi setelah melakukan instalasi ulang OS X 10.8 yang bersih. Saya meningkatkan baru-baru ini dari 10,5, di mana saya tidak pernah mengalami masalah ini.

Saya menempel di bawah irisan waktu yang relevan dari saya system.log(yang melibatkan beberapa iterasi penutupan / pembukaan kembali tutup) - Saya tidak melihat ada yang membantu di sini.

Apakah layar menampilkan gambar gelap (menjadi lebih mudah untuk melihat apakah Anda membawanya ke ruangan yang benar-benar gelap), atau apakah lampu latar benar-benar mati (hitam di ruangan gelap, akan lebih terlihat jika Anda menyinari cahaya yang sangat terang pada layar)? Saya ingin tahu apakah ini masalah perangkat keras.
Kevin Reid
Apakah lampu latar berkedip sama sekali saat Anda membuka & menutup layar? Sebaiknya berolahraga sedikit engsel dengan cara ini sambil menonton dengan cermat. Kabel ke display melewati engsel dan bisa menjadi aus.
Ashley
@Ashley Tidak, masalah ini tampaknya tidak disebabkan oleh engsel / konektivitas. Tapi Anda mengingatkan saya, saya lupa untuk mencatat: layar menyala sangat singkat sebelum menjadi gelap. Ini bukan karena gerakan tutup - saya membuka tutupnya, tunggu sebentar, lihat flash, dan melihat layar gelap.
Yang
@KevinReid Saya tidak yakin, saya tidak mencobanya. Saya akan membuat catatan saat ini terjadi.

Mengingat ini terjadi setelah instalasi yang bersih, tidak ada kesalahan dalam log, [EDIT: dan masalahnya terputus-putus] , sayangnya saya mencurigai masalah perangkat keras, yang kebetulan terjadi pada saat peningkatan dari 10.5.

Saya telah melihat masalah seperti ini yang disebabkan oleh kegagalan papan inverter (yang menghasilkan daya untuk tampilan lampu latar).

Saya akan merekomendasikan membuat reservasi di Genius Bar di Apple Store dan minta mereka melihatnya. Tapi ... masalah ini bisa sulit untuk didiagnosis sementara itu berselang, jadi mungkin tunggu sebentar dan lihat apakah itu semakin buruk (yang kemudian tidak begitu baik untuk Anda, tetapi lebih mudah pada teknisi).

Sementara itu: saran kecil - alih-alih menahan tombol daya ketika Anda menemukan masalah (yang tidak memberikan perangkat lunak kesempatan untuk membersihkan), cobalah ctrl- alt- cmd- eject, yang seharusnya dimatikan dengan lebih aman.

EDIT: Saya lupa satu hal penting - coba mengatur ulang SMC , karena saya percaya ini mengontrol daya ke inverter.

Tetapi mengapa hal-hal tiba-tiba akan kembali normal begitu saya melakukan reset? Terima kasih atas tip tentang reset yang lebih aman, BTW.
Yang
@Yang Beberapa spekulasi: mungkin lingkungan daya sedikit berbeda saat bangun-tidur, dibandingkan dengan boot-dari-dingin, dan inverter tidak lagi mampu mengatasinya. Secara terpisah, saya bertanya-tanya berapa kali Anda terbangun dari tidur dibandingkan dengan boot-from-cold? Dalam kasus saya, mesin saya boot dari dingin mungkin sebulan sekali, tetapi terbangun dari tidur beberapa kali sehari, jadi bahkan jika kegagalannya benar-benar acak, saya akan lebih mungkin melihatnya saat bangun dari tidur. Sayangnya, ini semua spekulasi berdasarkan intuisi bahwa ini merupakan perangkat keras, bukan masalah perangkat lunak.
Ashley
@Yang By the way, saya telah menambahkan dua hal lagi untuk jawabannya: lihat suntingan saya.
