No boot, charge makes sound, but no display
I have an A1708, macbook pro 2017 non touchbar. It currently doesn't have an SSD in it. I wondered why I can't boot it? I plug it in and it makes the charge sound, but nothing on display, not the charge sign at all. The screen has been tested elsewhere and works fine. I wondered if it needs the SSD in it to actually boot? It also illuminates on the caps lock key but not illuminates keyboard.
Is this a good question?
