Hi!

In Lenovo ThinkPad T440, any modified bios can be flash using hardware SPI programmer only, exactly the same as described in the first post of this thread.

So, for creating backup (dump) of bios you need to use hardware SPI programmer only. Just read carefully the first post on the first page.

I've have just successfully read the bios from my T440s and wanted to share info:

 

I purchased this from ebay:

 

https://www.ebay.co.uk/itm/273673803002?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=C1P_QAXrTEO&sssrc=2047675&ssuid=_WX6HXDFQ32&widget_ver=artemis&media=COPY

 

I used this software:

 

https://forum.laboneinside.com/viewtopic.php?f=35&t=76

 

The main problem I had was getting a connection with the clip, after a few attempts I realised the clip was not quite on the chip properly. One it was connected the 'Detect' function worked fine in the software:

 

 

The chip in the Lenovo 440s is a Winbond W25Q64FV as in the picture. I hope this info is helpful to someone.
