The key(?): I've only encountered this problem on one previous X131e, which I chose to send to the repair depot in Memphis, TN. I'm using the same HMD 1.83 that I've used for 20+ other X131e's of the same specifications and same motherboard FRU #. Simple enough except that for whatever reason, the replacement motherboards they sent me won't remove write protection from the EEPROM. The problem: I have four X131e ThinkPads that all have/need new system boards, which of course means updating the MTM/Serial# after the installation. With that being said, you would think that Lenovo themselves would be able to help out, but no. Hello, first off, I'm a Lenovo Authorized Service Technician.
