My Beelink GTR7 7840hs, USB4 not working (rear USB4) Cannot use eGPU (TH3P4G3), cant use USB C Monitor Already newest BIOS (V38), All Driver updated Please help

Hello there, Please send us a picture of the SN on the bottom of the PC. Please press delete key as soon as you turn on the PC, so that you can go to BIOS. Please send us a picture of the Main page. We will check if you need to update the BIOS.

Here it is : Cant use USB C Monitor and eGPU

Hi there, your BIOS is the latest one. Please go to AMD website and download the auto-detect program.It will update some chipsets and video drivers automatically. It will identify and install appropriate drivers for their AMD hardware. The program works by scanning the user’s system to detect the installed AMD hardware components, such as graphics cards or processors. It then compares the detected hardware information with a database of AMD drivers and software versions.

Already done Update all drivers include AMD Auto Detect Chipset Update USB 4 Driver Rear USB C cannot use external display or egpu

So, whats the solution? USB4 at rear port not working No configuration in BIOS to Enable or Disable USB 4. I saw another BIOS from another brand (Same chipset) have configuration in BIOS for USB 4, but there’s nothing in beelink Bios

Hi there， how about you send the item back for checking and repair ? Please send email to support-pc@bee-link.com for the return address

I already sent an email. So there is no workaround for this problem remotely? I was serach about this problem, and I notice, many GTR7 owner have this problem too, their USB4 doesnt work. Its work before, but then its become not working. Is that software or Bios related?

Hi there, it doesn’t necessarily have something to do with the software or BIOS.

Update : After communicate via email with beelink, still no real solutions for this. They ask me to send the unit and pay for all the shipping and repairs myself, which was too expensive for me since I was overseas. So another dead end,, Its really weird, because I have several mini pc older than beelink GTR7, and all USB4 works fine, but this unit USB4 does not work well, and the support service does not have a real solution for this problem, even though many GTR7 owners experience the same thing. I am not buying this brand again.

This app, didnt make different,, still no detect egpu or usb c monitor.
*Thunderbolt is for Intel, not AMD.

The problem is not windows setting or windows driver. Its in 100% beelink BIOS.

① Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. On Save&Exit page, please click Restore defaults, press enter to confirm, then press F4 to save.
② Please try another operating system. What OS are you using now ?

I am also experiencing the same issue with the USB port on the back of my GTR-3550 not working properly.
Has this issue been resolved since then?

I met the same issue. I’ve identified a significant limitation with the USB4 port on my GTR7.
The USB4 port appears to have
insufficient or non-functional power
delivery capabilities, resulting in
connection failures when devices are plugged in directly.
Currently when direct connections to the USB4 port with (USB storage, phones, eGPUs, etc. ) fail to be recognized by the system.
But the USB storage work perfectly
when connected through a powered
USB Hub (I have not tried this on the dock)
I think the port is capable of data transfer but error property power delivery function. This can issue of bios

Gemvn Hello there,

Please uncheck the save energy in the device manager—universal serial bus controller–USB hub—properties–power management—uncheck “Allow the computer to turn off the device to save power”

Gemvn

I have tried to turn off this feature on all USB hub in the universal serial bus controller section, but it has no effect.

The USB4 port cannot recognize any devices even before entering Windows.
In addition to I have also tried connecting to the Dock through the Thunderbolt 3 port but was unsuccessful.

Another note is that both of 2 USB4 ports are always automatically checked after resetting the computer, although the remaining port is not.

Gemvn Did you reinstall the system before ?

That’s correct, I have reinstalled the Windows 11 operating system including chipset/graphic drivers for GTR7 Pro from the official website.
Everything works fine except for the connection on the USB4 port as described.

support1 Hello, I have reinstalled the operating system as instructed. Although option “Allow the computer to turn off this device to save power” can now be unchecked, but nothing has changed.
The two USB4 ports (rear) still do not recognize USB storage devices if I plug them in directly. Devices such as Thunderbolt docks are also not recognized.
I still don’t understand why USB storage devices are only recognized when plugged through a powered hub. Is there any setting in the BIOS related to this issue?

Gemvn Hi there, ①please fully reset the BIOS by unplugging the PC, removing the CMOS battery for 5 minutes, then reinserting it. ② If the problem persits, the problem might be that the USB4 PORT is defective. You can send the item back for checking and repair.
