I updated my bios version directly when I got it last July. I have the GZ301ZE. I see the last bios version is from May, so I already have that one.
I uninstalled the ASUS System Control Interface v3 from Device Manager > System Devices. Then I reinstalled it with from: https://www.asus.com/support/FAQ/1047338/#V3
It gave me a notice that NOT all functionality was compatible with my hardware, but gave me no indication of what was not compatible precisely.
Yes, I am plugging the cord into the upper USB-C port next to the led, so not the one near the bottom with the other docking-related ports next to it. I will record a video of the behavior when I am home again tomorrow. For now: I attached a screenshot of the message of what occurs when I just plugged in the Thunderbolt cable, and the device is not recognized. When it is recognized after one or multiple restarts everything works fine, and the devices connected to the Thunderbolt turn on correctly. The last time it did work, I had the Thunderbolt port plugged in before I started the computer. I am not sure if this works consistently. I will try again multiple times tomorrow.
Thank you for looking into this!
Hi @AmberE ,
Regarding ASUS System Control Interface v3, you can download the version for GZ301ZE from here.
Additionally, I'd like to confirm if you are using the power adapter that came with the device?
This message is intended to inform you that for optimal performance, it's recommended to use the original power adapter to ensure a complete laptop performance experience. The provided information is for your reference.
Sorry for my late reply, I was working at another location so couldn't test further. Which driver contains the System control interface on the link you sent? I see a lot of drivers, but am not sure which one would contain it. I reinstalled the Serial IO bus one now in the hope that was it.
My docking station does not allow for your power supply via that port, but even if I attach your power supply to the second port, the Thunderbolt device is still not recognized (which is my main concern, I know about performance limits without the original power supply).
In the meantime I also noticed that sometimes if I continue working or just leave my pc alone while it does not work, suddenly the Thunderbolt device is detected and everything works. This sometimes takes 5 minutes after startup or plugging it in, sometimes an hour or more, sometimes it does not seem to happen at all. Once it works, it works until I unplug it or turn the system of. Even if I touch nothing after shutdown (pc, cable and thunderbolt device), and start it back up, I'm back to the same problem of just having to get lucky for it to work at some point.
I think maybe this laptop is just not checking enough in the drivers whether there is a Thunderbolt device attached? I never had these problems with my previous laptop. There it always detected it instantly after I plugged it in (same cable and Thunderbolt setup).
