    Ok, I will make some pads for 0R resistors to choose between pins. thanks for response

    I just did last check before making PCB and I see reset circuit (98 PLT_RST#) on gerald's schema is actually connected to S_DGPU_RST (pin 92). I am little bit confused which is the righ pin. Can you give me a hint please?

    Yes, I have 7pcs. But I wanted more than one so its not problem. I already have one soldered in my first not working version So I hope 7 will be enough :D. This site was first where I was able to get less than hundred pcs.

    Hi, I didnt have much time recently. I want to work on that during Xmas. I already updated my schematics and now I need to redraw a board. When I finish I plan to do some tutorial for everyone (if I will be successful ). I got my ultrabay conenctor from: https://www.verical.com/pd/te-connectivity-power-connector-2199015-1-4586152.

    @Swung Huang Looks great, is it your PCB available somewhere? Which cables are you using?

    It is not possible to use SLI for two different GPUs. You can use GT750M for native display on laptop and have it as second monitor.

    I had i5-4200M, than I upgraded to i7-4800MQ and I think more powerful gpu than GTX1070 will be bottlenecked by CPU. 8x PCIe is not a problem.

    My first version was made by some local manufacturer because I don't believe it's possible to do 0,2mm tracks via toner transfer method + you need to double sided PCB, which is not that easy at this precision.

    I am not sure how long it takes for me to get promoted, can you please send me this pdf as PM?

    Thanks very much for advice, as soon I will have these modifications done I will let you know if it works. Thanks, when I get promoted I will check your schematics

    He did not. I asked him for schematics and some advice, but he only responded on a part of my question (about trasistor switch of PSU). Ultrabay port has all signals as PCI-e 8x, in different connector, but there are some more signals (for SLI for example). Oh really? Here it is, I am not pro in PCI-E signals so it may be completely wrong . eGPU_Zakyn.pdf

    Hi, I had the same idea, but Gerald wanted to keep his plans (which I totally understand), so I found Lenovo schema and tried to design adapter by myself. I have already soldered PCB, it was not that hard it just take some time. It is not working yet, but I believe I just overlooked or misunderstood some Lenovo tags from schema. When I will make it work I will definitely release whole project for everyone.
