Hello!
After a repair, my lenovo ideapad 330-15arr shows this in the lenovo vantage:
SN: INVALID, PN: INVALID, BIOS: 7WCN38WW
I noticed that these values have been erased or the repair shop replaced something on the board and never wrote these values back (maybe replaced the bios chip or smth else. They did not explain much)
Is there a way to write what is missing?
I guess these are BIOS/UEFI values that I need to edit?
I tried with H2OSDE but it enters read only mode.
can anyone provide please steps on how to do it?
