Elitebook 840 G6
Microsoft Windows 10 (64-bit)

My laptop won’t boot up. Caps lock button is lit, blinks off once every 5 seconds. When the Caps lock button blinks off, power button blinks twice. Charge port light flashes between white and amber 10x, then off.  

I have tried the Windows +B, Windows +V, and just B buttons; none work. When I hold the power button, all lights go off after 10 seconds, but continue the same pattern as soon as the power button is released. 

From what I’ve found so far, it seems like this is indicative of a CPU failure, so I’m fearing the worst here.
