After booting fresh windows 8.1 my touchpad/sticks works for a half minute, then both are unresponsive.
My usb mouse always works.
I replaced my keyboard bit the problem remains.
What part should i replace?

If the system used to work properly before Windows 8 was loaded, then I think that points to a software/driver issue. If, on the other hand, you did not use the T440 before Win8.1, then I would try another operating system, be it Windows (7 or XP) or Linux or even a DOS program that uses a mouse. If they work there, that would tend to eliminate the hardware.

The problem is the hardware.
I wanted to have an idea what I should replace first. I already replaced the keyboard, but that was not the issue. The stick still does not work after a few seconds, and the touchpad also does not work after a few seconds of usage.

To be absolutely sure, boot from a Linux Live CD (such as from
http://www.linuxmint.com/) and check if they work there.
If yes, blame W8.
