Stuck at Apple logo screen and not booting
I recently replaced logic board, battery connector, and DC-in board. I was excited to hear the chime and see the Apple logo. Well, it doesn't get too far after that. I tried SMC, NVRM, PRAM reset, even fsck -fy. Nothing worked. Interestingly, the DVD drive makes its usual noise at power on but does nothing when I try to insert any disc (won't pull the disk in as it should). When I power on without the hard disk, it comes to flashing folder icon with question mark. Do I need a new HD and/or optical drive?
Esta é uma boa pergunta?
