Lenovo X220 and Lenovo X230 keyboard connector candidates part2

I still don’t know which connector do they use. I made a list of the connectors they could have used but didn’t use.
A guy took those photos (he connected it to the T60 but by USB not using the connector)

AA01A is no longer on sale and it is similar but it not that one:
(this one has metalic borders and a strange ending)

The old thinkpad T60 used the JAE AA01B-P040VA1

IL-312 connector looks similar but the borders are different.

The WR connector looks very similar but I got samples and saw they’re not the same.

Ok the WB3 is very different so it is not this one.

So maybe it is not made by JAE (or, the worst case, it is but it is a private connector)

Molex makes this and it is very similar but it is not the same.
Molex slimstack connector: http://www.mouser.com/pdfdocs/Molex_SlimStack.PDF

They’re not Panasonic AXK5F-6F connectors.

They’re not Morethanall connectors (and some look very similar)

UPDATE: I’ll try the molex ones. Update2: I still haven’t tried the molex ones but I made another post here
