Hi Sergeant Thank you for your offer. I trust your experience, even though my sources were official Lenovo manuals. Perhaps the second part of their 'solution': get the machine serviced' is the way to follow, if we get annoyed by use of the Esc-button. I am not competent to work at that level anyway.

Hi Hamid I found you question, looking for a solution to the same problem. Now I'm back to tell what I found: A German language forum had a discussion some years back on th problem, see: http://thinkpad-forum.de/threads/22528-T20-mit-Fehler-0189-Invalid-RFID-Configuration-Information-Area Several other links in a Google lookup (rfid error lenovo) refer to User Manuals, for example for T540, in particular to page 134: Error: 189 Invalid RFID configuration information area Solution: The EEPROM checksum is not correct (block # 4 and 5). The system board should be replaced, and the UUID needs to be reinstalled. Have the computer serviced. In the German language forum one member told that a solution was obtained when "the serial number was written to the EEPROM by use of a Hardware Maintenance Diskette" where UUID might be identical to the Serial Number (of the machine?). Let me know, if you can use this and perhaps help me along. I have no idea of where to obtain a maintenance diskette or how to use it. For the time being I make do with the Esc-button.
