t480 BIOS update

[vinvinsu]

Hi, I have a thinkpad t480, the BIOS won't update via Windows update or manually. Fwupd doesn't work either. Here is a dump of my bios. Could it be updated to version 1.44 please?

The serial is PF0VNLX0.

Double check the serial number, distinguish between zero and letter O.

The serial number is correct.. Copied directly from System Settings in KDE plasma.

Correct. How do you define it correctly ? I searched for this serial number on the Lenovo website and it led nowhere.

I checked in the BIOS as well, and it is the same Serial, with the zeroes being zeroes with lines slashed through them signifying so. I don't know why the serial number lookup doesn't work. But I'm sure that it's the right serial.
