What is X220 DOCK UltraBase Pinout

[wyczes]

Hi, I'm trying to reroute sata III from dock to msata connector or making second msata connector. But i can't find on the internet the pinout of dock in x220/t420 etc. :>. Does someone know the pinout or have a schematics?

You can use T420/X220 schematics, since they include docking port pinout.

Ok i found it http://plan9.stanleylieber.com/hardware ... matics.pdf
It's too bad i've already bought ultrabase for my x220 to find out pinout but it cost only7$ :>.

Can I ask how you found it? I'm looking for a schematic of x220's external slice battery...

Cudne do Pozdrowienia :>
I just did a google search. There are tons of paid schematics but managed to find a free one. I think you might be able to find a pinout on dock schematics. My second project is to make DIY slice battery. I've already made an external sata hdd on the bottom of my x220. I'm planing to use a cell phone battery as i can get them cheap. Or maybe i will put second battery on the lid
