Black screen after changing out HDD
After changing the hard drive, I plugged it in for the first time to check that everything was working. I unplugged then plugged in again and glued the screen and since black screen with the same symptoms and led 4 off. I don't understand how this could have happened knowing that I had disconnected the power. An idea ?.
