Hi everyone, I hope you can help me.
I need to know if I can change the palmrest of my laptop (t470 20HE), with a new one with fingerprint. My laptop condition is "in warranty" so, how i can do it? What is your advise?

My advice is not to do it. When you take a T470 apart, you remove the bottom cover and start taking out parts. (motherboard, storage, LCD, etc.) The last piece you get to is the palmrest. You might think about an external reader or maybe selling your machine and buying one with the fingerprint.

Thank you for your answer, but maybe there was a misunderstanding. I thinking about tell Lenovo assistance to do that for me, if is possible.
I read other threads and the only differences are palmrest with an hole for the fingerprint and fingerprint reader.
I was just wondering if anyone have done an upgrade when the device was still under warranty through Lenovo to not lose it.

This is a simple task and should take no longer than 15 minutes.
The palmrest assembly is classed as a CRU (customer replaceable unit) and is easily removed / replaced.
Remove the screws from the underside of the Thinkpad case in the area of the palm rest.
Note: You do not have to remove the base cover.
If your palmrest is a one piece integrated unit that includes the keyboard surround bezel then you will need to remove additional screws from the undersides.
Once the screws are removed the palmrest will unclip from the chassis, take care not to damage the ribbon cable. Remove the ribbon cable from the plug on the system board.
Plug in the cable (there is only one) from the new Palmrest/Fingerprint Reader (FpR) unit and clip the palmrest in place and refit the securing screws.
Full instructions and pictures are in the T470 User Service Manual, you can download it for free from the Lenovo website. Your warranty will not be invalidated if you are installing a genuine Lenovo new part / assembly.
You will need to download the appropriate FpR driver for you OS from the Lenovo website and install it to enable the FpR.

The last post is NOT CORRECT. That is the way that models T430 and earlier worked. The system board and the LCD are held in place by being screwed to the keyboard bezel (palmrest). There is no separate structure frame as there was in older models. Here is the list of parts that must be removed first (the service manual).

The above suggested procedure bears no resemblance to that in the T470 HMM:
It's as richk described up-thread.

Thank you all for the answers.
I will not touch nothing, but my request is still unsolved. It is possible to call Lenovo assistance to claim this upgrade against payment of a fee?

Yes. You can call, but I would expect you would be charged for the required service. I have all the needed tools and I'm experienced. It would take me a full hour to do it and I would expect it would take as long for a tech to do it.
