I installed a new keyboard and it can smc reset and the power button works. but nothing apart. no boot picker e.g. I am wondering how this can be explained if the alt key (smc reset) is working. I am aware that on the board side shift, ctrl, alt and pwr are separately wired but the board, trackpad/cable are good. The keyboard was tested working prior installing and as another keyboard now tested on the same board improvised works as well the only idea I have is that I damaged the keyboard flex cable while installing it into the case. But why hell smc reset and power are working then ? Anyone has an explanation ? best regards
