I have received my kit this morning and it has been soldered by a friend with his soldering station. The mentioned pin has been cut and insulated with a paint dot.

Both monitor calbes were included so 13.3 FHD and 12.5 so called 2k ones. The btoker just did not take photo of the 13.3 one.

So far the screen works perfectly and is really amazing comparing to the original one. No flickering or anything with 16GB installed.

USB 2.0 dongle works (I suppose it gets te signal from express card connector as it also works woth the USB3.0 cable not connected).

SATA not tested because I do not have anything to connect to at the moment.

USB3.0 does not work :( I connected my mobile phone to see if there is a votage - nothing happens.

The SATA cable is connected as you have shown with the red ovals, if we call it straight connection the USB cable uses inverted connection. I have checked the continuity between the connectors (to see of the tapes sat well etc) with a multimeter - looks OK.

Any suggestions ? Machine is running windows 10, bios 2.70 (x230 i7 processor).

The only idea I have is to ask my friend to reslder the upper connections of the board (he begun with these, maybe he soldered not long enough to get the touch with the pins...)

Did you forget the big "holding" solders at the top ? Top left is the 5v line.

You should have continuity between some pins on that little chip and the top left big solder.

Also, congrats on getting that new screen working.

That's exactly what I am going to do. Waiting for my friend to give me the missing third hand :)

Just found the usb socket pinouts here:

http://www.mouser.com/ds/2/445/692122030100-473682.pdf

If we look at PCB LAYOUT in the middle of the first page on this document we can see there are the 9 pcb lines going to the socket, in case of our interface we have:

9 TXP = pin 126 on docking connector
1 +5V = from the big pin on docking connector, yes it has been soldered yesterday.
8 TXN = pin 124 on docking connector
2 DATA- = pin 130 on docking connector
7 GND = taken from somewhere
3 DATA+ = pin 132 on docking connector
6 RXP = pin 120 on docking connector
4 GND = taken from somewhere
5 RXN = pin 118 on docking connector

So I will measure the continuities here.

I used the docking connector pinout from here:

http://plan9.stanleylieber.com/hardware ... matics.pdf

There are useful photos:

https://forum.51nb.com/data/attachment/ ... 2bpj1z.jpg

I will post the results in the evening.

BTW what is the purpose of the little chip near the USB 3.0 connector ?

Looking here https://forum.51nb.com/data/attachment/ ... w7lylu.png it is just in parallel with the socket.

VICTORY !

The continuity was OK - some pins can be measured some not (probably there are some protection circuits so it is not electrically 1:1 connection on all pins from dock connector to usb3.0 lines on the second board).

After resoldering just with a good amount of soldering flux one of USB3 pins on the dock connector seemed to have not enough of solder applied.

We assembled the machine and just after start I saw a blink of cmd prompt - it installed something for newly detected device.

After plugging of a mouse the we have heard a windows USB device connected sound :)

The last remaining thing to test is the msata - but it has to wait till next month, now the budget for IT is over :D

BIOS to be patched as well - but I will test the setup as is for some days.

My little experience with the dedicated windows program for brightness control, maybe will be useful for someone:

[OSD]
; Default 3000 -> time of display of brightness slider on screen, reminds the old style thinkpad slider, in miliseconds
TimeOut=2500

; 0-100 Default 100 -> as the name states, opacity of the slider
Opacity=100

; 0x000000-0xffffff -> back color of the slider, 0x000000 is white
BackColor=0x000000

; Ctrl Alt Shift -> this section is used in X220 case, no need to use on X230, default Fn+F8 / F9 buttons work to adjust the brightness
[Hotkey]
;Br_Up=Ctrl+Home
;Br_Down=Ctrl+END
;MonitorOff=Ctrl+F12

[Set]
; 0-15 Default 12 -> default brightness after windows boot
Brightness=12

; This parameter must be set to 1 to take ito account the values.below. If set to 0 they have no effect
AutoStart=1

; time in minutes on AC connected to reduce brightness to the given value from 0 to 15 and to switch off the screen
ACReduceBrTime=45
ACReduceBr=6
ACMonitorOffTime=60

; time in minutes on battery to reduce brightness to the given value from 0 to 15 and switch off the screen
BatReduceBrTime=3
BatReduceBr=0
BatMonitorOffTime=15
