How to fix error 2200: Machine Type Invalid and Serial Number are invalid. Device out of warranty.
Edit: This is now fixed! Thank you very much u/Bone08154711 !
So this is annoying. Newly decommissioned laptop, and reset the bios to install a Linux install, and after the reset and reboot, suddenly I had no serial # and model # (Thinkpad E14 Gen 4 - 21ED0049US).
Now, I know what it's serial number was, and I can get its model number from Lenovo. The problem I have is paying Lenovo to set this back into the BIOS (when this should never have been a problem in the first place).
Does anyone know how to fix this without needing to open a paid support ticket ?
