    My X220 recently had the system board replaced at a local Lenovo Authorized Service Provider. They were only supposed to replace the fan but the speaker connector broke when they were removing the board. Windows now isn't able to read the machine type. System Update doesn't work because of this. CPU-Z and hwinfo64 show the machine type as qqqqCTO as if it were blank in the BIOS. Machine type is there correctly in the BIOS correctly, but they left the system board serial number blank. Could that be causing this?

    In case someone else runs into this problem: I fixed the issue by running the BIOS update utility and using the option to change model number. There's a note in it that says to delete what's there and leave it blank to restore it to the factory setting. This did the trick.
