HP Pavilion x360 13 a200nw Caps Lock blinking every four second

[Jakub9000]

Hi,

I have a problem with my laptop HP Pavilion x360 a200nw. Basically, suddenly the computer get black screen and the fun starts on full speed. I could not turn off the computer in any way (long pressing power button does not help at all), I connected/disconnected the power cord but without any effect - the computer was black, the fun on full speed.

I have opened the case and disconnected the battery. Then obviously fan switch off.

Then if I pressed the power button the fun again switch-on full-speed, the screen is black and no other signs of live, no beeps, no blinking. 

But, when I disconnected the battery again, connected power cord and press the power button the fan switch on slow speed and I saw on the keyboard that the caps lock is blinking, around one blink every four seconds. After one minute the fan again switch to full speed - no other signs of life. I have connected external screen but nothing.

What could happen? Can it be that the mother board is dead or cpu? I haven't done any BIOS upgrade, the Windows 10 was not upgrading at the moment when the computer went black.

Is there a way to fix it?

I've already followed the instruction on that page and it seems that either CPU or Graphic card is broken (if I correctly read the table with the codes).
