Mac doesn't boot from internal HDD but does from USB plug?
Hello there :D
I'm stuck in a weird position here. My roommate gave me a MacBook Pro mid-2010 which had vodka/orange juice spilled on it. Not working, I tore it down, cleaned the hardware. And as I saw the fan spilling when i took everything apart, I said myself I can fix it !
I mount everything back in, turn it on : Grey screen Yeah !! I then installed everything start to use it. But it has crashed. No way to boot the system up : question mark on a folder. PRAM reset put it back on the road again. Then it crashed again.
I did all of the resets I know something about (PRAM, SMC), but nothing. And the weird thing is that it boot up normally when the very same drive is plugged externally through USB port... I'm actually using it to open this thread !
Whats wrong with the mobo ? (I did unplugged energy sources for days, just in case)
Cette question est-elle utile ?
