Re: Is it possible to replace the button-less touchpad of a T440s with the 3-button touchpad of a T4

Succes!!

 

Popped right into the T440s, and worked right away with the current driver. The thinkpad special tab in mouse properties even shows a touchpad with buttons and special options for that now.

 

This is so sweet. My T440s went from an annoying machine just waiting for an upgrade to a T450S or X1 carbon, to an almost perfect machine..

 

For the procedure itself, a lot of the stuff specified in the HMM as needed to be removed, was really needed. Only things i had to disassemble was HDD, Batteries, Fan assembly, wires for the speakers and fingerprint reader. Then the systemboard could be loosend and angled up so the touchpads could be exchanged. I took off the keboard, but now i can't really see why that was needed.

 

Next up, the X240

 

Final result:

I would love to do the conversion but, unfortunately, I am 'mechanically challenged'! It could be a very costly exercise on my part. Smiley Sad

Regarding the comments on the disassembly, the instructions in the manual are for removing the keyboard bezel, not exposing the touchpad from below so it could be swapped while the bezel and keyboard were still in place. You couldn't take out the keyboard bezel without removing the keyboard. A lot of interest in the touchpad swap comes from owners of the 15.6" machines - T540/W540. That process should be MUCH easier. You remove the battery, the door on the bottom and the keyboard. The keyboard bezel can then be removed. I always caution about replacing parts that are not considered customer-replaceable on machines that are under warranty

Yes i got it from the EBay link above.

 

A small update re. the driver. My T440S had version 18.0.7.57 of the synaptics driver. A quick system update installed a never version .100 that did not work with the buttons. I also tried an even newer X1 driver. That did also no work. So back to the working version... no big problem!

18.0.7.57 with this synaptics driver everything works? Two finger scroll? Middle track point scroll? Everything?

Nice work Smiley Happy  Do the new buttons sit low enough that they won't scuff the screen when closed?
