My Thinkpad a21e is refusing to boot, displaying the above errors instead.
I have seen some mention of a Hardware Maintenance Disk to restore the serial number, but I can neither find such a disk for this machine (2628-CXU), nor can I get into the BIOS.
I have also seen some mention of being able to have the EEPROM reprogrammed, which is alleged to be the source of the error.
Finally, I have seen an 'abandon hope' message indicating that the mainboard is faulty and need to be replaced.
Anyone with real knowledge about this out there ?
