Looking into possible hardware mods for the W530

#1 Post by ljuvtliv » Fri Mar 09, 2018 5:07 am

I've been looking at the Kendo-4 WS illustration from "2012 Mar. ' 09" and have noticed a few things,

Firstly the CN100 appears to expose the pins on the spi hidden under the magnesium frame.
Soldering the appropriate flex connector may enable us to streamline the flashing for development.

Secondly QM77 provides 8 pcie Lanes of which four are in use,
I'm guessing one of those is eaten up by the Gbit lan controller and it's half speed nonsense.
One goes to the sdcard reader which can be moved to a USB bus with the appropriate controller.

What I would like to look into is the feasibility of building a slice to sit inbetween the QM77 and the system board,
Passing the used pins 1:1 while drawing out the 4 pcie lanes.

System board < Slice < QM77
pcie/thunderbolt <

Next to the USB port on the back there might be space to mount a usb-c connector,
The thunderbolt controller goes onto the daughter "slice" card.

It's only pcie 2.0 but four lanes with tb3 on top of everything else would be impressive and lengthen the lifespan of the system.

The design I have doesn't seem to be the final version of the board,
Do we have access to the final revision?

Do we have the "Intel Platform design guide"
In the Kendo-4 WS from Wistron they reference it with a "Please see Doc No 29635"
W530, T530, T530, T530, X230.
Can't have too many 30's.

Full name is: Chief River Mobile CRB Platform Design Guide 29635 / IBL
where CRB = Customer Reference Board

No idea about the rest.

IBL = Intel Board Layout? Just a wild guess.
Thinkpad4by3's Law of the Universe.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

Hello everyone
soo for the CN100 the connector is:
BM20B-SRDS-G-TF
SHDR-20V-S-B
and the pins:
SSH-003GA-P0.2
For the Schematics and Datasheets:

The only complain i have with this laptop is the lack of thunderbolt... and TN screen...

I have seen that the schematics/drive link requires permission to access. @edmalho I have sent a private message to you including my mail, I would be glad to have the aftermentioned documens if you guys still keep.

So did the QM77 slice/extra pcie idea work? Because I have seen a similiar idea on retropcmania via this video and would it be possible to combine the unused 4 lanes with expresscard to get a much higher egpu throughput?

Also one last thing, since the same model comes with k1000, k1100 and k2000 m gpu's on different mobos, would it be possible to directly reball a k2000m to a k1000/1100m gpu'd mobo or are there any alterations required?
