Screen Blank - 3 Blinks slow, 2 blinks fast

[ComfyChris]

Hey guys, 

I've bumped my laptop by accident and I now can't see anything on screen. I get three slow blinks and 2 blinks fast on the caps lock key. I can hear the fans going, and the LED light on the power button is working.

I've tried plugging into an external monitor and pressing the F4 key as well as the FN+F4 function to see if I can force it to change screens and nothing is happening unless I'm not doing that correctly. 

I've also tried the classic switching it off and on again as well as leaving it run for a moment but nothing appears to be happening. Due to the above what sort of issues could this be? And what can I do to ensure I can get it back up and running?

Any help at all would be greatly appreciated! 

Thanks
