Solved! Lenovo Yoga C940 crash after connecting Razer Core eGpu

[Lil_Kaniwi]

Everytime I connect my Razer Core (Gtx 1070 8gb) to my Lenovo after a few seconds the computer crashes, without BSOD. I cannot reboot until I hard shut down by holding the power button --> wait a few seconds --> press power button. Usually it works second try.

Anyone know what could be wrong? I have updated drivers, and windows, reinstalled Nvidea software with no luck.

BIOS of the laptop is up to date?

Eventually the power supply of the eGPU case is not that good anymore
