Elite book unknown flashing error signal - cannot boot

HP Recommended
HP Elitebook 840 G3

Hello there, 

 

I have an elitebook 840 G3. When trying to boot all of my keys flash on and off and continue to slowly blink. The boot fails and this flashing continues indefinitely. The caps lock/num lock lights do not flash as I have seen in many other examples, but instead the entire keyboard backlight lights up. I’ve tried a number of restarts and chargin my laptop for 30 minutes but still having same issue. I should note that my battery was 75% charged when the issue happened so it isn’t due to low battery. 

let me know your thoughts. Thanks in advance!
