MacBook Pro not showing login, just white screen, cable loose?
I cleaned the fan in my macbook this morning. When I turned my macbook back on everything was working fine, it loaded ok, except that I can't see anything on the screen.
I know it has loaded because the screen starts to go to sleep or dims after couple of minutes. What I see is a grey/white screen depending on the brightness. I'm sure behind the grey screen is my login screen.
When I was cleaning the fan, I unplugged the three connectors (the hard drive, and the two next to that). I also had a look at the data display connector which I think may have caused my problem. But I did plug them all back in, the mac can't be that sensitive can it?
Is this a good question?
