Invalid Motherboard Service Tag

I bought some months ago a Dell motherboard from AliExpress. The model is LA-B843P para Dell Inspiron 5458 5558 5758 specifically for Dell Inspiron 5558. Once I was trying to update the drivers and the service tag was required, in this case, the Service Tag shown is 5156151.  But I had no success, the service tag seems to be invalid.

Did I purchase an illegal product? If not, can I register it?

Hi, did you go to this website: https://www.dell.com/support/home/en-us? ? There's a part called "Identify your product or search support" with a link entitled "How to find your product identifier". Click on it, and follow the instructions to identify your product.

There's also an option to let the website detect it automatically for you (right bellow the last link with the instructions).

Do you have SupportAssist installed? You can find more information about your notebook there. I think there's even an option to update drivers directly.

Here's the support page for your notebook: https://www.dell.com/support/home/en-us/product-support/product/inspiron-15-5558-laptop/overview
You can try to download drivers from that page. There's also the manual that you can read about your device.

Have you tried updating the drivers with the Windows option?

Hi Lorenzo!

I couldn't update the drivers directly because it requires my service tag. Just for additional information, my service tag is shown below after running the command in Ubuntu to get more information about motherboard system.

Serial number / Service tag: 5156151.

I'm using Linux because, for some reason, probably related to an invalid motherboard serial number, Windows is impossible to run.

Dell support for Linux machines is very limited and for this reason, I was just able to update my BIOS system after finding the file for my laptop model. There were no problems during BIOS update process, but the same was not enough to solve the problem related to the serial number/service tag.
