... Macbook
I replaced a faulty superdrive, upgraded the hard drive, reset the pmu, and now the damn thing won't start up at all. No chime, no screen. It sounds dead, but I am getting power to the magsafe adapter & it does seem to be charging the battery. I made sure the orange cable was properly attached & the ram was seated properly. I'm a Mac Mini semi-expert, so this one has me stumped. I hope to hell I didn't somehow fry something on the motherboard! Anything else I can try?
