I press the power button, and I get a black screen and some HDD noise. The keyboard never lights up, I never hear the boot up chime. Eventually it is just a fan running and the sleep light on. Things I have tried. Reset PRAM Reset the SMC Safe Mode Boot Tried different RAM. Any ideas? It does have the NVidia 8600M graphics card. Any chance it could still be under that recall thing they had going on awhile back?
