Bios errors on T41 - 0187 EAIA and 0191 system security

[Glaurung-quena]

I bought a T41 with broken hinges, figuring I could replace the hinges from my parts stash. That was annoying but I managed it. Then I realized it was not clearing two bios errors even after replacing the very dead cmos battery and resetting the time.

As best I can tell, there is no BIOS password set, but I still get these errors on every restart -

0187 EAIA Data access error
0191 System Security - Invalid remote change requested.

It looks like the motherboard was replaced at one point - the serial number fields are blank (both for system unit and for system board) and the UUID field is all X's.

I tried using the reset serial number utility, it spat back an error that the thing I was trying to change is locked.

Can the motherboard be saved, or do I break this laptop up for parts?

Your system may need to complete serialization process. Try to find and boot Hardware Maintenance Diskette (DuckDuckGo the file i7tm38us.exe) and complete all missing information in BIOS with it. After those are flashed, system should boot normally. Try to skip the errors with Esc key.

I could not get it to boot the maintenance diskette. Based on search results for those errors, I decided the BIOS was toast. Fortunately I lucked on an inexpensive replacement motherboard on Ebay.
