Computer won’t turn on. Pattern seems to be 4 sets of 3 blinking white lights on caps lock

HP Recommended
Microsoft Windows 8.1 (32-bit)

I have an HP Model 15 - f018dx that won’t turn on. I have made note of the pattern of the blinking lights but don’t know what to do next. Pattern seems to be a 4 sets  of 3 blinking white lights on the Caps Lock key 

I removed the battery and lights are still blinking when AC powered. 

What next?


Many thanks
