Problem: Razer Core X is not charging my laptop

Hi everone, I hope I can find some help in this forum for my problems with my egpu. In December I bought the Racer Core X alongside with the Lenovo Yoga 730. I get more graphics power, no problems with detecting the gpu etc, in that aspect, everyting works fine. But there is one thing that is making my head ache a lot. It's the fact that the laptop is not being charged while using the egpu. Nor through the case itself, nor through the standard powercable from Lenovo. I tried my luck on the Razer Core support, which was very friendly and did his best to help me, but couldn't tell me more than they would contact me if they solved it (so far nothing).
Any help is appreciated.

-Matt

@mattb so if you plug the original charger and the eGPU at the same time you are unable to charge right? and as soon you disconnect the eGPU the yoga starts to charge with the original charger connected? that would be very weird, I think you would have to contact Lenovo instead of Razer, seems more like a laptop problem, do you have another TB3 device that charges laptops? I know it could be very stupid to ask, but have you tried only connecting the eGPU without the lenovo charger, if not maybe that is the reason that it doesn't know how to negotiate which source of power to use.

Hi, thanks for your answer. So there are several different approaches I tried:
razer core only--> charges sometimes, but would stop after a couple of minutes. I couldn't figure out a scheme. It's randomly charging or not
razer core and power cord--> same result
disconnecting razer core while power cord is in --> begins charging
I don't have any other tb3 equipment unfortunately.

It could be the thunderbolt 3 cable, do you have another one? Try ordering an active 2mt 40gbps 100w cable. If it doesn't work you can return it.

What I did was plug the included Lenovo charger into the second port (even though they said that only the first from the left side could be used for charging) before plugging the egpu, this I could charge my laptop from the brick and use the egpu at the same time. If you want to connect some other devices to that USB-c port, just get a dongle with passtthrough USB c power
