Hi,

I experienced similar issues in replacing the touchpad on my X240.

First: make sure you have a touchpad that is for your device apparently the
T440 and X240 do NOT have the same touchpad and connector layout!
(This was my first mistake)

Second: if you replace the touchpad, also replace the ribbon cables. They
are not made to be connected and disconnected too often.

In my case the whole thin worked after I got the correct new touchpad and a
new ribbon cable.
To get everything in place, I needed to completely disassemble the machine
though. I hope the T440 is a bit easier to do.

best,

Hendrik-Jan

P.S. I know it is no consolation but due to this I also had a mouse
connected for about 4 weeks as there was no internal pointing device
anymore.
