UPDATE2> I have managed to extract windows licence key from old bios chip. Is there a way to insert licence key back to BIOS?...

UPDATE> I was able to find laptop serial number as well as motherboard serial number (there is a sticker on motherboard with long number and 3QR codes) through lenovo utility disk 2.02

I however still dont have my WINDOWS licence back ... any ideas?...

Hi,
had T490 with faulty bios chip. Bought chip out of ebay and soldered on. Laptop starts and works however serial numbers of laptop and motherboard do not match.
I have updated laptop model number.

1) I did not find the way to update laptop serial number - I have this one.
2) I dont know where to get my motherboard serial number and how to update it. Is it somewhere physically on the mainboard? How do I update it?

Hope to find someone to help me with this as I am hitting dead end at the moment.

Many thanks

Miro

Would you be able to advise what do I need to do to disable faulty onboard memory on T490?...
