Lenovo X220 and Lenovo X230 keyboard connector candidates – part 3

cucumber eyesI got an schematic in English/Chinese and it says the connector on the motherboard is a JAE-CONN40A-1-U1GP

but I have not found any other reference to it and it seems it cannot be bought alone (without a motherboard on ebay or similar)

If this schematic turns out to be true a lot of info can be obtained from it.

The internal name for the Lenovo x230 seems to be Dasher-2 and Winstron developed the schematics. They somehow got leaked.  I still wish I had a connector to map the keyboard table/keys without breaking it but I’ll manage somehow. With all the info available many things seem possible now.

Well, the internal name of the Lenovo x220 is Dasher-1 and the schematic is here:

It seems the x230 uses an 8051 and a x220 uses an H8S/2113 (page61) so it won’t be super easy to extract keyboard code tables from their embedded controller update blobs but I continue in my quest.

I had to share this. Searching for dasher-2 I found the next paper and anyone familiarized with Víktor Pelevin will find it amusing. Please give me another cucumber: https://www.lsuagcenter.com/NR/rdonlyres/9BD67509-BDB8-4E77-9A6F-E96F0A783DC5/81387/B844StakedCucumberProduction.pdf
