andrev Hello Andrev, The lastest BIOS version of your machine is the V505. If your machine already has this version, you don’t need to update it. Have a nice day!

Bom dia Comprei um SER PRO e apos algumas atualizações houve conflito do dispositivo de Bluetooth , preciso do Drive correto, pois o do Windows 11 so da conflito e não funciona

wich is the file name with the lastest bios to download?

Hi Team, I have an SER9 32GB of RAM. Serial Number is YHX374LG8020 SER9-L-321TBVK0W64PRO-DP/XA My current version is: STX.3XX.SER9.V103 Can you please link to the correct bios to flash? There are so many different versions in the SER9 Bios folder.

I have a Beelink SER5. Here are the numbers from the case in case the photo is not available to you. 9Y.UP3190834B10; SN:Y58003CG30853; SER5 MAX-E-321TBEJ0W64PRO-DP/XA. The current BIOS shows version 5800H602 from 6/15/2023 13:49:16. On the files page, 5800H605_LK_20240906_2024-09-14_9-26-52.zip is available. Is this the latest BIOS for my machine and can I flash that file directly or do I need to incremently flash the previous 603 and 604 BIOS files first in order? Thanks.

Hi, I tried the BIOS you provided, but it does not solve the problem :(

I didn’t get the exact same steps as in the guide you provided, but I guess the bios has been correctly updated, even though the “Core version” has not changed, still 5.19 (only build date is newer) :

Is it dead or is there something else I can try ?

Thanks.

Hello there,

You can try to clear CMOS :Please turn off the PC , unplug the power supply and HDMI cable , and press the CMOS pinhole for about 10 seconds. Ten minutes later, plug the power supply and HDMI cable, turn on the PC again.

Please wait about one or two minute, if you can go to the system.
Please repeatedly press delete key as soon as your restart the PC, go to BIOS. Go to Boot option, enable fast boot, press F4 to save.
Here is the tutorial ：https://mega.nz/file/XypwTISY#DVT0BsjOgiPkZ-drQaj88JH9Z7f7qpKGP2E3nMHW8ms

I suggest you try let stand the BIOS battery 1 to 2 hours to install back to try again, this is the tutorial: https://mega.nz/file/fz5HHaZQ#8HXWZaZD4SoqnkIuhsBeapSo6Kt4kzXNIyiTS1ORY8w

Then please try the tutorial we sent before.

Have a nice day~

I’ve having this exact same issue! Same model, same BIOS, same symptoms. I believe I’ve narrowed it down to windows attempting to perform secure boot certificate updates. I’m working through steps to try to manually rotate the certs but the first steps are always to update the BIOS. That said, like you, I’m also on the latest BIOS version (at least according to the Beelink rep that replied to you).

If I have success, I will follow-up here but I would like to avoid returning my computer for repairs…

Good news — I got it working! Here are the steps that fixed it:

Prerequisites (in BIOS)

Enter BIOS (press Delete on startup)
Set Secure Boot to Standard/Windows UEFI mode (not Custom)
Use Restore Factory Keys to reset to default Microsoft certificates (you may need to first set the mode to custom, restore factory keys, then back to standard)
Save and boot into Windows
Verify Secure Boot is active by running Confirm-SecureBootUEFI in an elevated PowerShell (right click on powershell -> run as admin) — it should return True

Apply the certificate update (elevated PowerShell)

Reset the trigger key, then re-set it:

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\SecureBoot" -Name "AvailableUpdates" -Value 0
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\SecureBoot" -Name "AvailableUpdates" -Value 0x40

Then fully shut down (don’t just restart), wait ₁₀ seconds, power back on, and once at the desktop, restart once more from within Windows.

Verify it worked

[System.Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI db).bytes) -match 'Windows UEFI CA 2023'

If this returns True, you’re done!

Notes:

The full shutdown (not restart) is important — it forces a proper UEFI handoff that a normal restart skips
The key trick was resetting the registry value to 0 first before setting it to 0×40; skipping that reset is likely why earlier attempts failed for me
No custom keys or advanced BIOS configuration needed

ccampanale

Unfortunately I found out soon after that the command to confirm the applied certs was a false positive. The PC froze up sometime later.

Here’s the event in Eventviewer:

Updated Secure Boot certificates are available on this device but have not yet been applied to the firmware. Review the published guidance to complete the update and maintain full protection. This device signature information is included here.

For more information, please see https://go.microsoft.com/fwlink/?linkid=2301018.

And I’m trying the following command (in elevated powershell) to prevent Windows from trying to apply that update for now. Hopefully this will help prevent the freezes.

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\SecureBoot" -Name "AvailableUpdates" -Value 0

I’ll report back but, for Beelink support, are there BIOS version updates in the works to support these certificate updates which appear to currently be unsupported and causing issues for some?

Hello there,

Could you please send us a picture of SN code(two lines) at the bottom of machine ?

Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. Please send us a picture of the Main page, we will check if you need to update the BIOS.

Have a nice day~

Hello there,

Sorry for the trouble.

Please try to flash the original BIOS file to solve the problem.

I have sent you the BIOS file, please check your PM.

Based on the SN serial number you provided, it is possible that the malfunction of your machine is caused by insufficient power supply.

If the problem still persists even after resetting the BIOS, we recommend that you contact our customer service email support-pc@bee-link.com. We can apply for a new power supply with greater power to solve the issue for you.

Have a nice day~

Hello,

I am experiencing repeated unexpected restarts on my new Beelink SER5 Max (Ryzen 7 7735HS).

The system was recently set up with a clean installation of Windows 11 Pro. There is no additional hardware connected (only the internal 1TB NVMe drive). It is being used as a media server.

The system is logging the following in Event Viewer:

Event ID 41 (Kernel-Power)
Event ID 6008 (Unexpected Shutdown)

There are no bugcheck codes and no dump files generated. The BIOS setting “Restore on AC Power Loss” is enabled, which is why the system automatically powers back on.

Troubleshooting steps already performed:

Moved power connection from a shared power strip to a dedicated wall outlet
Confirmed BIOS is current (Version dated 9/25/2025, Core 5.24)
Disabled Global C-State Control in BIOS
No external drives or USB devices connected

The issue still occurs intermittently.

Could you please advise:

Whether there is a newer BIOS or firmware available
If there are known power adapter stability issues with this model
Whether this behavior suggests a defective power adapter or motherboard

Serial Number: B77355BF507989. 24576MB DDR5 memory BIOS version 5.24 Project Version SER50 0.04 ×64

Thank you for your assistance.

ccampanale

Beelink CS-June I’m not sure how but the secure boot certificate update eventually applied. But the freezes continued. I was eventually able to stop the freezes by changing the power scheme to “high performance” and disabling fast-boot.

FYI @alexspurbeck

The BIOS sent seems to have resolved the issue. The machine has not restarted in 3 days. Thank you!

Hello there,

We are sorry that the solution we provided doesn’t solve the problem.

We suggest you take your machine to your local repair shop.

Or you can consider sending the machine back to China for repair, but since your machine is no longer within the warranty period, you need to pay the corresponding maintenance costs and freight, is that acceptable to you?

Have a nice day~

Yann

Beelink CS-June
No, it’s not worth it.
I’ll try some fix myself, otherwise it’ll end up in the trash.
Thanks for your help anyway!
Best.

Good Morning, I have a Beelink Ser9 PRO HX 370
Serial Number BHX375CG00120
My Current BIOS version is 12/17/2025 SER9T407
I am getting some Hangs / Screen Freezes / Restarts. The hangs and freezes require a hard reset.
What is the latest bios version for my system and where may i download it.
Thanks
Lee

Beelink CS-Rose

Lross78550 Your current BIOS version is the latest and you don’t need to update.

Here are some potential solutions:

1.Please change another power supply.

2.Overheating. If your PC is overheating, please check if the fan spins. You can also turn off the turbo boost. Go to control panel —power option—change to High performance— change plan setting—advanced setting —processor power management— change both 100% to 99% , click save.

3.Update graphics driver: Please uninstall the graphic driver in the device manager and install the new one. Here is the driver source :https://url.bee-link.cn/JDaT tutorial：https://buildin.ai/share/005e2ade-fda8-4c92-89b1-3819a1fee1dc
