[QUOTE="silverdagger, post: 1842386, member: 403926"] Ok, so I stripped her down and re-seated every ribbon cable. I put her back together and still the same. So I tried the PRAM reset with both the built-in and then with an external k/b (Windows+Alt+P+R as non-Mac k/b)... still no use. So next I tried an SMC reset with the built-in keyboard and I saw the led colour flash on the power connector. I though this could be a good sign... but no. Still no k/b and pad. :( EDIT: OK, so I just tried a hardware diagnostic and I received this message: Error: 8000000000000003, Cannot load 'EFI/Drivers/TestSupport.efi' Status: 0x00000003 [/QUOTE]
