I've tried every trick in the book. My black screen is impenetrable, my keyboard is toast, and the disc in my drive won't come out. When I say I've tried every trick- I mean it. I've been trying for two weeks to get this thing to turn on. I went to the Apple store, the Nvidia card test failed- meaning I have to pay 300 something dollars to get the hardware replaced. So, I need to back up my computer. Problem is, the keyboard is fried and holding down T during start up doesn't have an effect. I plugged in a USB keyboard and held down T on that with no progress (It worked on the host Mac I have plugged into my comatose Macbook). The USB ports work on my Macbook Pro, because my phone can still charge from them when powered on. 15" Macbook Pro (late 2008) connected to a 2010 Macbook Pro via Firewire. anyone else have this issue?
