Converting a W4 into a touchscreen?

I have a W4 that I keep shattering the screen on. As there is some cross-compatibility between the T series & W series, this time, I ended up with a pristine T2 screen thats compatible and works fine. Any idea if I can get the touchscreen part of it to work, though?

I actually have a T5 as well that I guess I could take apart and see how its done. But these notebooks really are a pain to dissemble without a manual, so I'm trying to avoid it.

Alternatively, anybody have the repair manuals for these guys?

 

You may use one usb port on the machine.

ohlip

 

It did occur to me that the wires from the touchscreen might work when tapped into USB as they both use 4 cables. But how do I know which wire is which so I don't blow out the touchscreen card?

And while I'm at it, maybe I can wedge a little USB port into the computer so I can still have 2 USB ports going out?

Has anyone ever done this kind of conversion?

 

Yes they have

 

Anybody do a writeup on it, by any chance? I've never found one on google in the past (this is my 3rd screen for the W4 - i think i've been treating it like a real toughbook. Funny, because my T5 goes on site constantly and is perfectly fine).

 

It was on a cf-28 or cf-29 , not on this model
Buried somewhere in the threads

 

hmmm, still can't figure out which wires should be soldered to which parts of the USB port. All 4 wires are white and I can't trace where each one comes from on the little board attached to the touchscreen.

 

Anybody have a lead on this or know where I can go to find out which wires (from the touchscreen) go into which parts of the USB port? My laptop is still in pieces and I'd like to figure out if I should drop this project and put it back together, or if I get a W series touchscreen laptop.

thanks!

 

Solved -

Pins on the chip:

35 ---> D-
36 ---> D+
15 ---> 5v
18 ---> 0v (ground)

Simply solder the pins (or wires) into a USB port and force install a touchscreen driver (and software) from a T2 or T4.
