Hi everyone, Until now I did not deal much with bios and modifications to it. But I have baught a used T430 from ebay and I get the 2200 error with wrong Serial number/Model Number. I tried to change it to the right one with the Maintenance Tool from Lenovo but it still shows the error 2200! Here my short question to you: Is it possible to avoid the bios check of the Serial/Modelnumber of the Laptop? And can I somehow read out the actual Serial with Software? Thanks for your answer and time!
