I have a Beelink Mini S 8GB RAM and 500GB HD (MINISV1-A-8256SDOW64PRO-A). Unfortunately it’s no longer under warranty but I’d really appreciate some guidance on the problem it’s been having: Everything is working perfectly (with Windows10 or Linux) except when I try to reboot or switch it on before it has completely cooled down, which usually takes about 5 minutes. If I try, it lights up the blue power LED, turns the cooling fan but doesn’t show any video. If I don’t switch it off, it stays in this state permanently. And when it’s like this, if I try to switch it off using the power button, it switches off the blue LED, stops the fan and seconds later switches on the LED again and turns the fan, but it’s still on the black screen. If I insist on switching it off using the button, it repeats the behaviour: it restarts and remains on the black screen. Then I have to remove the power supply and wait for it to cool down. Then it restarts normally. What I’ve already done: Changed the thermal paste on the processor Cleaned the RAM contacts Removed the glue residue left by the backup battery that was stuck to the motherboard Checked the voltage of the backup battery (OK) Thoroughly sanitised the motherboard with isopropyl alcohol Checked and reset the BIOS configuration ((JTKT001 ×64 - 04/12/2022) via the CMOS reset button (10sec. without energy). Changed the monitor I’ve tried booting with ethernet, without connecting peripherals (keyboard, mouse) What I’m thinking of doing: ?Reinstall the BIOS ?Reflow the processor ?Check the capacitors (this will be a bit difficult as the board will have cooled down by the time I remove it). But I’d be very grateful if anyone could give me some advice.

If your PC is overheating, please check if the fan spins. You can also turn off the turbo boost. Adjust power settings: Adjust the power settings on your PC to optimize performance and reduce heat generation. Lowering the maximum processor state or using power-saving modes can help.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.

Fortunately, it is not overheating. I have been monitoring the CPU’s operating temperature and it is around 60 degrees Celsius. The FAN is working properly. I am using Windows 11 as my operating system, which apparently does not stress the CPU. So it should not be an overheating problem. But as strange as it may seem, after turning off the system, the video does not load while the temperature goes down (that’s what I believe) because I have to wait about 5 to 10 minutes. Then it starts up normally and is able to work for hours and hours without any problems. I can’t understand what is happening. Could there be an overheating sensor in the CPU that is not working properly?

LaBenedetti ①Please test the RAM with Memtest software to see if the RAM works fine. ②Please 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.

The RAM is working properly. I used memtest and the result is that it is OK. BIOS was already configured with Fast Boot.

As everything suggests that the problem is related to the temperature of the cpu or gpu, I decided to experiment. I improvised by fitting an extra fan blowing air into the unit and sealing the other inlets to force the air through the cpu/gpu vent. As a result, I managed to bring the working temperature, which I’m monitoring via the Core Temp application, down from 60 to around 43 degrees Celsius. But even so, the only change was to shorten the amount of time it takes for it to restart giving video. No restart was possible. It continues to behave in the same way: the fan turns on, the blue LED lights up but the video doesn’t come up. Then you just have to unplug it. But now, with the temperature lower, it’s almost immediately giving video and switching on normally via the button. I only need a few seconds when the unit is unplugged.

But the problem persists.
I would appreciate any further suggestions.

Please go to device manager to uninstall the graphic driver and then restart the PC.
Check for software conflicts: Uninstall any recently installed software that might be interfering with the system’s startup or video functionality.

LaBenedetti

I did this and there was no change.
I don’t believe it’s a software or driver issue.
I also installed some Linux distros to see if it changed the behavior.
I installed Lubuntu, Linux Mint, MX Linux and the behavior is the same.
Everything points to a hardware (or BIOS?) issue, especially because when the CPU cools down, the boot is normal.
My suspicions continue to be BGA solder on the CPU/GPU, capacitors (or some other component) with values altered by the temperature or some temperature sensor (on the CPU?) providing incorrect readings at boot. I’ve been monitoring it during operation and the readings are normal.
Is there anyone who’s an expert in hardware who can give their opinion?

Hi La Benedetti
I have the same problem and beelink team hasn’t helped me yet!

LaBenedetti

Hi Ago
I’m surprised. I thought I was the only owner of a Beelink with such a peculiar defect. So as this is a recurring situation, it would be quite plausible for Beelink to pay special attention to us in order to try to solve our problem and, perhaps, improve the hardware of their new products. I’d even suggest sending my unit in (with a replacement, of course) to be checked out by the factory if that’s the case.
Could someone from Beelink support comment on this?

Although the defect is characterized as a hidden defect, which here in Brazil is covered by the Consumer Protection Code and does not establish a warranty deadline, support simply informed me that my unit is no longer covered by the 1-year warranty established from the date of purchase. I do not know if this is Beelink’s final position. It was definitely not what I expected.

See the response I received:

"Hello Luis,
Good morning.We sincerely want to help you and sorry for the inconvenience.
As you could see the policy on our official website,beelink provides a one-year (12-month) limited warranty for consumer electronics products.
Thanks for your understanding and have a good day！"

LaBenedetti Hi there, we are sorry for the inconvenience, but as you also mentioned in the first post, the warranty of your PC is expired. So if you send it back for repair, you need to cover the shipping cost and possible repair cost.

LaBenedetti

Hello Support 1. Thank you for your reply.
Sorry if I wasn’t clear but in my first post I mentioned that the 12 month warranty had expired. But I had to reconsider it as a ‘hidden deffect’ as I realised there were other customers with the same problem.
As for sending it back for repair, as long as the shipping and possible repair costs are compatible, it could be.
How could we get an estimate beforehand? Where would this assessment, estimate and possible repair take place? Is there an authorised workshop here in Brazil?

support1

LaBenedetti Hi there, sorry ,there is no authorized workshop in Brazil at the moment. About the repair fee, we are unable to decide it yet, we need to check the PC first.

kimdt Hi there,

Here are the possible solutions :
① Power - saving mode: Check if the monitor has any power - saving or sleep modes enabled that might be causing it to not display on the first boot. Disable such modes or set them to a longer timeout period.

② Please turn off the PC , unplug the power supply and other USB devices, then put the pin in the CMOS pinhole and press it for about 10 seconds , restart the PC after ten minutes.
Here is the tutorial https://url.bee-link.cn/5FdW

③ Please update the chipset driver , https://url.bee-link.cn/PAGj

I am currently using the s12 pro model and I have the same problem. The monitor screen does not display on the first boot, and when I press the button to turn it off and then turn it on again, it works normally. I have to turn it on twice every time I use it. It seems to be a compatibility issue between the monitor and the main unit, and it seems that the bios needs to be updated to solve the problem. Even after updating to the latest bios version 106, the problem was not solved at all.

kimdt

I’m currently using the msi mp243x monitor. I have several other PCs at home, and when I connect them to the monitor and test them, there are no problems at all. The problem only occurs on the s12 pro. I’ve already installed the latest version of the chipset driver and reset the coms several times. But the problem still persists. I think there’s a compatibility issue between the monitor and the s12.

kimdt Hi there, did you try other monitors ?

kimdt

I brought an old monitor that I used before and tested it. When I used that monitor, the symptoms related to the s12 booting problem disappeared. After conducting several tests, I confirmed that when the s12 was connected to a monitor with a compatibility issue, the monitor did not simply not display the screen, but the main unit stopped booting. When connected to a monitor that had no issues, when I pressed the power button on the s12 that had completed booting, the device went into standby mode. However, when there was a compatibility issue with the monitor, the device did not boot. When I pressed the power button a second time, the device did not wake up from standby mode, but booted from the beginning. It seems that the s12 clearly has a compatibility issue related to booting with a specific monitor, and this issue seems to need to be resolved through a BIOS update.

kimdt Hi there, sorry, there is no newer BIOS for this PC at the moment. How about you try antoher HDMI cable ?

kimdt

I tested it with 4 different HDMI cables at home, but the symptom did not improve at all. About 30 percent boot at once, and the remaining 70 percent do not boot at once and have to boot twice. This is quite annoying. There are users in Korea who have similar symptoms with various products using n100 cpu. They say that if they turn off the monitor completely, turn on the main unit, and then turn on the monitor again, the booting goes normally. It definitely seems that some products using n100 cpu have compatibility issues with specific monitors.

kimdt Hi there,could you please send us a picture of 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.

kimdt

I have already emailed beelink about this issue and they replied that my device has the latest version of bios (s12 pro n100 ADLNV106).

support1

kimdt Ok, I see. If we have newer BIOS, we will let you know.
