I have some questions about the use of Razer Core X Chroma (hereafter referred to as Core) that I need advice on.

Environments:

Matebook X pro 2019 with 40GB/s bandwidth Thnderbolt 3, Windows 10, eGPU of GTX 2060s in Core

Processor Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz 1.80 GHz
Band RAM 16.0 GB (15.8 GB available)
System type 64-bit OS, x64-based processor

Version Windows 10 Professional
Version number 21H1
Installation date 2019/12/14
OS internal version 19043.1023
Experience Windows Feature Experience Pack 120.2212.3740.0

Issue 1.

Laptop loses connection with the Core after reboot and must be reconnected by manually re-plugging the thunderbolt cable while the laptop is powered on.

Here is the scenario in detail:

Currently the computer is connected to Core via Thunderbolt 3. Core is connected to a power cable, an external monitor, a mouse and a keyboard. Everything works fine. However, if you reboot Win10, the system will lose connection with the Core like it wasn't connected. The monitor is not lit and all external devices are not recognized. The following steps must be strictly followed to reconnect before the system can work properly again.
a. Unplug the computer's Thunderbolt cable
b. Turn off the Core power
c. Wait for more than 30s
d. Turn on the Core power
e. Keep the laptop in normal power on state and connect the Thunderbolt cable. Voila, everything is back to normal. 

The operation is very tedious. I have tried the method provided in this official link https://mysupport.razer.com/app/answers/detail/a_id/1924/~/razer-core-usb-ports-are-not-working
It still doesn't work. Must follow my steps above. Every time the system is updated and rebooted, you need to unplug it all and start over.

Issue 2.

In order to avoid frame drops caused by eGPU, the igpu that comes with the cpu is disabled through the device manager. But then the backlight of the laptop screen is always on, even though the display is completely black screen. It is weird and not power-efficient. How can I fix it?

 

Any advice is appreciated. Thanks.

Not sure if its related, but here are my BIOS settings:

@westxu,

 

Issue 1.

Does this problem happen when you restart or when you shut down, or both?

The first thing I would do is disable Windows Fast Startup.

Secondly, have a fiddle with your Thunderbolt BIOS settings. The way systems communicate with Thunderbolt devices varies greatly depending on how manufacturers have designed them. You could also look through your BIOS for USB settings, such as USB Sleep State and Power settings. 

 

Issue 2.

You can try disabling and then re-enabling the iGPU, which should illeviate your stuttering and turn off your backlight. This works for me with my current setup. Let me know how it goes!

@boltoway, Wow didn't expect such a quick response. It took me weeks to try to contact Razer through their official support website, and still got no response.

Thanks a lot.

 

Issue 1:

This problem happens both when I restart and when I shutdown and power on again. As far as I can remember during over a years of using this setup, I never booted with everything work without having to reconnect. What bothers me most is when windows auto update and restart itself, then I'm forced to do all these procedure once more. Windows Fast Startup doesn't take effect during windows update right? Does this mean it's not Windows Fast Startup that causes this problem?

And the BIOS stuff. I post some screenshots of all my BIOS settings above. Could you take a look at them for me please? In case you didn't see it, here is the link .

 

 

Issue 2:

Yay, it works! Re-enabling the iGPU turns the backlight off! But you're sure that this won't bring the stuttering back right?

 

Appreciate it.

@westxu, I suppose that is why this forum exists! I am glad to help.

 

Issue 1:

I can't really diagnose a possible BIOS fix without being able to do trail and error with your specific BIOS. I recommened just changing relevant settings (Thunderbolt, USB and Security) one at a time to see if you can find the fix. 

I would disable fast startup anyway, as it is a useless, troublesome feature that doesn't really have an impact on high performance SSD based systems anyway.

One thing you could attempt to do on your system is as follows:
1. Turn off your computer through Windows and wait until your system has shut down completely.
2. Turn off your Razer Core X Chroma at either the PSU switch or power-point.
3. Wait a couple of minutes to ensure any residual power has been drained.
4. Turn on your laptop and wait until it boots into Windows and then turn on your eGPU. If this does not work, try turning on your eGPU first and then turning on your laptop.

I use an Aorus Gaming Box which has a notorious issue where if you turn your laptop off and leave the eGPU on, when you turn your system back on it will only provide power but not have USB or GPU functionality. To mitigate this, the eGPU has to be turned off at the socket to drain its power. I specifically set up my system to take advantage of this otherwise annoying problem by enabling "wake on AC power" in BIOS. This means that when I turn on my eGPU, it automatically powers on my laptop. If your BIOS has this feature, you could possibly try it as a work around for your issue. 

 

Issue 2: 

No, the stuttering should not be present, at least until you next restart or reboot your system. You may have to do it upon every system startup, but it should fix both your backlight and stuttering issue.

@boltoway,

 

So I tried your process:

It works, but still doesn't survive a reboot. Nonetheless it inspired me to simplify my reconnect process. I don't have to unplug and re-plug my egpu after every reboot now. All I need is turn the egpu switch off - wait about 30 secs - and turn it on again. 

It's not perfect, but better anyway. I'll keep an eye on other possible solutions. 

Thanks again.

@westxu, No problem. While it isn't ideal, I am glad I could help.

@boltoway, I got it worked.

 

I bought a smart socket which I can control programmatically. And I plug my core into it. 

Then I create a task in windows's task schedular. Everytime my computer boots, it turn off the socket, wait 30 secs, and turn it on. It's just like an automatic version of me re-plugging it. 

 

It works like a charm.

 

I feel like a genius now.

@westxu, That is a great solution! So good to hear. I would love to see you detail it all in a build!

What smart socket did you use? I have been looking at using some to automate some of my system but haven't looked into it too much.

@boltoway, I just grab a radom smart plug I found. It's a Chinese brand named tuya. And they have a nice open api that I can call from python.
