I have a 2.4 GHz SR MBP. Purchased when the SR first came out - June 2007. Was working fine last night. This evening I opened the lid and it didn't wake up. I forced a shutdown holding power button. Now, whenever I turn it on the power light come on, the fans whir, the superdrive powers up, and that's it. Screen stays black, no hard drive activity. Tried resetting SMC. Tried starting from OSX disc. Tried safe boot. Reseated memory and tried the original Apple memory that I upgraded from. Nothing. I can't get my disc out either now. I have an appointment at Apple tomorrow. Is this all typical for a logic board failure?
