Alpha 864 power adapter connection cannot be powered on, unable to boot.

I just arrived at the alpha 864, my usb-c logic power adapter and plugged it into the socket. My alpha didn't turn on. Then I waited a few minutes for a loud current from the power adapter. Then the blue light turned on and the red light turned on. After a few seconds, the blue light went out. Hold down the boot button for three seconds and I couldn't turn on. Can't power? What should I do? help me
