Hey, I've got a bit of a hard case on my hands at the moment.
One of my co-workers informed me that her "MacBook Pro's screen was broken." She is getting a new one very soon anyway, as this is a MacBook 3,1 and she is frustrated with how slow it can be.
It turns on. The screen lights up. It goes to the gray boot screen, Apple logo, spinning tick wheel. But wait - what's all this garbled alternating boxes of pink lines? GPU failure? Oh wait, never mind, it's gone. Just an Apple screen now. Aaaand it's back!
And all that it'll do is sit on the spinning tick wheel with garbled display until suddenly, the spinning stops. Freezes.
I have only seen that once, and it was on a similar MBP with a fried GPU - overheated after being left on next to a window on a bright day...
But see, my co-worker's MBP WILL boot to Target Disk Mode. I can easily get all her data off. I even repaired the directory (as that is usually first thing I do).
It WILL NOT boot to an external drive, USB or FireWire. Same freezing tick wheel and garbling.
No, plugging in an external monitor does not help. It doesn't even display anything - no signal.
I am leaning towards logic board failure, but have read about issues with the HDD causing similar problems (though the display issues kinda rule that out)
I just want to know, for reference, what you think might be causing this problem.
There is a chance I may wind up with the laptop to break down for parts - wouldn't want to sell a bad component!
And...why will it boot to TDM but not a FW or USB drive?
I mean, it's convenient, saves me taking out the HDD and my adapter...
Thanks for any insight!
