W520 BIOS version missing and incorrect BIOS version displayed and other inconsistencies

When you go to the following link:

 

http://support.lenovo.com/us/en/downloads/ds018884

 

and scroll about 3/4 of the way down the webpage, it says that there is a v1.41 version of the BIOS (as shown below), and it also says that v1.41 is the current version of the BIOS, however there is no link to download v1.41 of the BIOS or the accompanying readme.txt file like there is say for v1.40 of the BIOS - see below:

 

Package | UEFI BIOS              | ECP                             |    Release

1.41        | 1.41 (8BET61WW) | 1.36 (8AHT42WW)    | Current Release

 

1.40        | 1.40 (8BET60WW) | 1.36 (8AHT42WW)    | 8buj19us.exe

                                                  | 8buj19us.txt

 

Also at the very top of the same webpage, it says that v1.42 is the current version of the BIOS NOT v1.41.  If you look at the Readme.txt file, it indicates that there was indeed a v1.41 of the BIOS released, however version 1.41 of the BIOS is not posted any where on the webpage.

 

Based on the other file name conventions, it appears that the file names for the v1.41 of the BIOS would be '8buj20us.exe' and '8buj20us.txt'

 

If you download the the alleged v1.42 of the BIOS at the top of the webpage and run the setup program, it says that it will install v1.41 of the BIOS!

 

Also if you go to the following link for W520 driver and BIOS downloads:

 

http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-w-series-laptops/thinkpad-w52...

 

and you select BIOS/UEFI from the pull down menu, and download the fourth link down (i.e., v1.42 of the Windows version of the BIOS update) and run the .exe file it ALSO says v1.41 when you run the executable! - see attached screen capture.

 

Lenovo can you please straighten all of these different problems out?  It is important that these BIOS update downloads and accompanying readme and version information are correct and accurate!
