This is too funny. I decided to do some housekeeping on my Thinkpad T42 Laptop and checked the installed driver and firmware versions against the latest updates available from the
Thinkpad web pages.
Currently, my Laptop's BIOS version is 3.12 (latest version available: 3.19), the Embedded Controller is at version 3.03 (latest version available: 3.04).
The BIOS README tells me:
- This BIOS version will only work with Embedded Controller Program
Version 3.04 (or higher). Please obtain the additional package,
Embedded Controller Program Version 3.04 (or higher),
and update Embedded Controller Program in the system with it.
- If you need to update Embedded Controller Program as well as the BIOS,
update the BIOS first.
OK, so I guess I need to update the Embedded Controller Firmware first. However, the README for the Controller Update tells me:
- This version of Embedded Controller Program will only work with BIOS
Version 3.13 (or higher). Please obtain the additional package, BIOS
Version 3.13 (or higher), and update the BIOS in the system with it.
- If you need to update the BIOS as well as the Embedded Controller
Program, update Embedded Controller Program first.
I think it's time to make use of my extended service contract and call their hotline. Or do I really have to update the BIOS from 3.12 to 3.13 first, then update the embedded controller to 3.04 before I can apply the latest BIOS update to 3.19? This is insane.
