What firmware version do you have, BTW?  I just stumbled across this new
driver/firmware package from Lenovo (seems they now only publish updates
for new Thinkpad models - don't know how to interpret that):
http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x250/downloads/DS101007

Looking at the contents it seems that there are now different firmwares
for different US operators (so much for the "worldwide" support...).

So I guess that you need that 'VZ' firmware for B13 support now, then?
Hey, there's your motivation to go dig up the Linux firmware tools from
Intel :-)


The firmwares are easily extracted from the Lenovo package by simply
installing it under wine:
