BIOS Dell 15 3510 la-l246p

Can you help me? I have a 3510 on which we replaced the BIOS. We used some BIN files and it boots, but it gives a Service Tag error. It forces me to press ALT + F6, but it never saves the Service Tag — we click “Save”, but after restarting it’s still blank. Any solution?

Sure, I’m attaching it.


When I program the BIOS, I get this “manufacturer mode” message, and it warns me that the Service Tag is missing.


I go into the BIOS, fill in the Service Tag, save the changes, but after restarting the same message appears again and the Service Tag is not saved in the BIOS.


Also, if I exit manufacturer mode, Windows won’t boot anymore — it gets stuck in a loop saying that the Service Tag is missing and to press F1 to retry boot, and there is no way out of that. When that happens, I have to remove the chips and flash the BIOS again, and then the same Service Tag problem starts all over.

It is in production mode and needs to buy a $35 patch
