I bought a brand new Ser5 Max 6800U 24gb RAM 1gbps LAN. I have been running Ubuntu LTS, just downloading files and transferring to an external hardrive. When I have several downloads going, and the CPU gets stressed, the PC randomly shuts off and reboots. No logs in ubuntu signaling anything going wrong. The PC feels warm but not overly hot - could still be thermal issues i guess? I’m looking to update my BIOS, can you confirm if this is the right file https://dr.bee-link.cn/?dir=uploads%2FSER%2FSER5-MAX-6800U%2FBIOS%2FSER5-MAX-6800U-Original-Version--ASER5009-for-1G-ethernet-24GB-RAM Any other ideas? If it keeps shutting down, I am going to return it or RMA. I’ve only owned it for a week.

I saw a Reddit post where the user said his power supply wasn’t providing enough power, and buying a 5a power supply fixed his issues.

orin719 Hello there, Don’t worry, the PC has one-year warranty. Please send us a picture of SN on the bottom of the PC and a picture of the purchase record. Here are some potential solutions： ①Please take out the RAM ,please clean the contacts of the RAM with a rubber. Here is the tutorial https://mega.nz/file/XqZX0TIR#_DtO2oa4aRP4bWtvxgKLj4QGhBpQ959cg5U3Yw4u1Cc or https://url.bee-link.cn/AzzB ②Please take out one RAM and leave the other one in it to test if the RAM is defective or not. You can also use Memtest software to test the RAM. ③Please 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. The BIOS of SER5 MAX 6800 has two versions. We need to confirm the original BIOS version of your machine first to better assist you. ④Please change another power supply. ⑤Overheating. 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. ⑥Update graphics driver: Please uninstall the graphic driver in the device manager and install the new one. Here is the driver file: https://url.bee-link.cn/UX3B Have a nice day!

@orin719 same issue, did the driver update help resolve this?

tanman81 Hello there, Could you please send us a picture of SN code at the bottom of machine ? Then we will send you the corresponding solutions. Have a nice day~

Hello, I bought nine units: AZW (Beelink) SER mini PC BIOS SER50004 (2025-09-24) Ryzen 7 6800U Ubuntu 25.10 Kernel 6.17.0-8 They all have the same issue, unexpected reboot… I returned two of them and got two new ones and got the exact same issue. This is more than just a random unit having issues, 11 units is not random anymore, it means a design issue.

goldyfruit Sorry for inconvenience to you. We recommend you revert to the original BIOS or replace the power supply. The original BIOS will be sent via private message. If you do not have a replacement power supply, you can contact support-pc@bee-link.com to obtain one.

Beelink CS-Rose I doubt that changing the power supply will solve this issue as it would means that the 11 PSU are bad which I assumed your QA would have flagged before packing (I hope) . So BIOS version SER5001 should solve this issue? If that is the case, do you plan to release a BIOS update with a fix as I assume that SER5004 had fixes/improvements in it (which I am gonna loose with SER5001 ) ? Thanks for the BIOS file.

goldyfruit We suggest you use a 19V 6.32A/5.26A power supply to check if the problem persists. Some users have resolved the unexpected restart issue by rolling back to the original BIOS or replacing the power supply. Rolling back the BIOS will not cause other problems. SER5004 is a code update version.

I too have a Ryzen 7 6800U mini pc that started randomly shutting down. Twice today and it wasn’t under any heavy load; just regular usage. BIOS SER50004 (2025-09-24) I’ve read there are problems with the power supply not being sufficient enough for the PC. Is this why Beeklink is suggesting “We suggest you use a 19V 6.32A/5.26A power supply to check if the problem persists.”? Why should I have to pay for a power supply if the one that came with the box isn’t good enough to keep the computer powered on? Beelink should ship me, without any costs, a power supply that’ll make this problem go away.

ajmxco Hello there, Sorry for the trouble. We suggest that you contact our after-sales email - support-pc@bee-link.com to apply for a 19V 6.32A power supply. Have a nice day~

ajmxco This worked great for me as a temporary solution. Once I received my new PSU, I was able to revert the settings back with no issues. Thank you for the recommendation!

Beelink CS-Rose

Calixoo We’re so glad to hear your PC is working properly again. Have a lovely day!

ajmxco

Received the new power supply they shipped me on their dime. It’s 19v 5.26A which is more power than the one that came in the box.

Good that Beelink is solving the problem with sending customers correct power supplies. It’s also a bummer this entire problem is happening for customers.

Just wanting to provide an update on this thread, this issue is still present in machines as of February 2026 on the new 7735HS units. Under any kind of load they are powering off.
