HP Envy x360 Dead After Arduino USB Connection

[C_O_O]

Hello HP Support,

I own a HP Envy x360 laptop purchased in the United States in 2023. It has been working perfectly until today, when I connected an Arduino Uno board via USB while working on a personal electronics project.

Shortly after connecting the Arduino (which was controlling an external fan circuit via a MOSFET), my laptop suddenly powered off and will no longer turn on. There are:

No lights or fan sounds

No screen activity

A full hard reset and unplugging of all devices did not resolve the issue

Does anyone know what the problem is and how it can be solved?

Thank you for your assistance.
