My Beelink SER5 5560U went dead one month right after the warranty ended. At first it would sometimes not start up, giving me fan spin but then silence and a black screen with no BIOS, but then if I pressed the power button long until it shut down and I started it again then it worked. I saw some other people report this. Since it only happened sometimes, I figured it was some BIOS glitch and I ignored it. But then, the last time it still came up, the system time reset to 1970. It booted to my desktop normally otherwise, but the system time made me suspicious and I made sure to backup some data just in case. Then I shut down, and attempted to boot again, expecting the worst. And yes, now it no longer boots, ever. I tried the obvious, like trying only one of the two RAM sticks and alternating the slots, and resetting the CMOS battery. Nothing, always a black screen. The only difference is that sometimes the fan spin will only go for around 5 seconds then it’ll turn off, power light staying on but no sound, and sometimes the fans will just continue spinning at high speed until I force the entire device off. It seems like either the power supply or the mainboard died in some way. Is this common? I saw somebody else post something similar. This is quite disappointing, it feels like planned obscolescence for sure. I haven’t had a computing device die on me like this for a long time.

…so it seems like the CMOS battery exploded and killed the board: Isn’t this something that usually happens to computers after 20 years rather than 2?? 💩 Seems like you sold this with a defective battery or something…?

hujet98hr9hjhw Hello there, Sorry for the trouble. Could you please send us a picture of SN code(two lines) at the bottom of machine ? We sincerely apologize for the unpleasant marks on the motherboard of the machine, which have caused you an uncomfortable experience. If your machine is still within the warranty period, may I ask if you would like to send it back to China for repair? We can reimburse you for the shipping cost of returning the machine. Have a nice day~

Beelink CS-June Thank you for your response. The CMOS battery exploded, if you didn’t see it, which seems to potentially be a manufacturing defect. Those aren’t just marks, it seems to be some acid or liquid that damage the board. My apologies for potential misunderstandings. Or I’m curious, do you disagree that the CMOS battery exploding after around two years is unusual?

hujet98hr9hjhw Hello there, The CMOS battery failure you reported is somewhat abnormal. Therefore, we would like you to return the machine for repair or replace it with a new one within the warranty period. Our technicians can inspect the machines and identify the causes of the faults, thus preventing similar issues from occurring in the machines in the future. Please believe that we truly want to help you. Have a nice day~

Thank you for your response. This happened right after the warranty ended, as detailed in my initial post. However, I’m not sure if warranty limits apply for manufacturing defects (if this is one). At the very least, this kind of CMOS failure seems disappointing.

hujet98hr9hjhw Hello there, Could you please send us a picture of SN code(two lines) at the bottom of machine ? If your machine is still within the warranty period, we can apply for repair services for it. Once again, we sincerely apologize for the inconvenience caused by the machine malfunction. Have a nice day~

Thank you for getting back to me. As I already specified above, this happened right after the warranty ended, after 25 months. The warranty typically lasts 24 months.

hujet98hr9hjhw Hello there, Perhaps we can apply to the supervisor for a slight extension of the warranty period for your machine. Please provide a picture of the serial number of your machine. Have a nice day~

Beelink CS-June I’m excited to hear that it might be possible. I sent the details to the bee-link.com support e-mail, along with a link to this forum posting. I would be glad if there could be a warranty extension. I realize that if you deny me I can’t do much about it, but I am hopeful.

I took out the SSD and did more testing. Using a different computer and an NVMe USB enclosure, the SSD seems quite alive:

But in the new Bee-Link PC, it won’t show up anymore. I don’t think there’s a problem with the fit, since I now removed it and placed it back inside but nothing changed, the SSD still won’t show up. (It did before for about 24 hours before all of this happened, I’m not sure what changed now.)

Hello there,

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

The issue you reported regarding the BIOS battery is not likely to be a leak of glue.

May I ask if the machine can boot up if the SSD that comes with it is replaced with an NVME card slot?

Have a nice day~

Thank you so much for your response! As I discovered, putting the internal SSD simply into an external USB enclosure, everything works fine again. Whatever happened made the internal NVMe slot suddenly no longer like the internal SSD, and everything else seems to be fine. (I even tested a high load scenario, the device is definitely running stable and no noticeable issues so far.) You wouldn’t happen to know what would possibly cause the internal SSD to no longer like the internal NVMe slot?

In summary, it seems like this went from potentially scary to just a minor issue, so I’m extremely relieved 😌☺

Hello there,

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.

It might be a problem caused by the failure of the internal NVEM card slot.

Have a nice day~
