CW-NAS-ADLN-K N100 No power

  Based on the video you provided, it seems the power supply might be incompatible or unsupported. Please try replacing it with a power supply of a different model. If you have a multimeter, after connecting the power supply, please measure the USB pins on the motherboard to check if they are receiving power. I recall that these pins should normally have power even when the system is shut down.

  If the above steps fail to resolve your issue, please try using tweezers or a metal wire to short-circuit pins 8 and 9 on the power supply connector to attempt starting the power supply, and confirm whether the power supply can start up normally. If you are not experienced with this procedure, you can search for relevant guides on Zhihu or Baidu Baike using the keyword: "How to start a computer power supply independently to make it work."
