X220 Tablet Antenna and mSATA SSD...

Hey guys! Just wondering if someone might have some insights into my issues:

 

I have a Type 4294-CTO X220T

 

1) I dissassembled the Keyboard and Palm-rest assembly to take a look at the mSATA / mPCI-E area today. I have a 3x3 Centrino card, but only 2 of the 3 connectors are connected. There are 4 antenna wires black, grey, red, blue. Only the Black/Grey ones are connected. Can I just connect one of the other two in order to get 3x3? I DID order a 3x3 screen!

 

2) Since I have 4 antennas does that mean I have a WWAN configuration, therefore I cannot use a mSATA SSD?

 

Here is my system configuration:

You might want to have a read of this thread.  As far as your antennas go, what colors are the ones that aren't being used?

Hey, thanks for the response! The other two are Red and Blue as I stated. The tips are wrapped and they are not connected to anything.

Page 76 says what colors go where.

Hmm... well that helps but I think this means that my antenna setup is 2x2 instead of 3x3 because I do not have a white cable. This is kind of disappointing because I did order the 3x3.

 

Can I just use one of the WWAN red/blue antennas for the 3rd WLAN connector?

It's not going to hurt anything to try it.

Re: X220 Tablet Antenna and mSATA SSD...

I have the same issue with my x220. so far support has not been helpful. I even had one tech ask me why it matters. aside from not getting what i paid for the 3rd anntena allow for higher wireless speed. his response was "oh"

yeah thanks lenovo support. anyway they could not find a part number for the MIMO antenna, but I'm still looking. its got to exist somewhere, right?. If i can get the part number and its not to expense I'll just order it and install it.
