I have an IBM Thinkpad R52 1858 - CTO. I would really like to have a fingerprint reader on this computer. Is there a spot on the motherboard to plug one in from another IBM. Like if I were to change the palm rest to one with the fingerprint reader would there be a place to plug it in?

Thanks
Brandon

Open up your thinpad to see if it has a Fingerprint reader UltraNav pad connector on board, if so then you can add one otherwise not however you can buy an external Fingerprint reader to accommodate your need.

So it just uses the same plug as the ultra nav? As in the touchpad or the trackpoint?

Trackpoint (a red stick on the keyboard and three click buttons below the keyboard) is part of your keyboard.

UltraNav pad cable is part of your plamrest and touchpad.

Carefully watch the following video:

Alright it plugs in with the touchpad, so on the new bezel is there just an extra ribbon that runs over to the plug? Also is the T42 the only Thinkpad with the fingerprint reader on it? Will that bezel fit on the r52 with out any problems or will something need to be modified?
Thanks

OK I found one really cheap but.... I can see where it plugs into the place where the ultranav plugs in but then where do you plug it into? Does it plug into. like here

Hardware Maintenance Manual (August 2005) - ThinkPad R50e, R51e, R52

Page 96.

You would need to change the palmrest bezel as the fingerprint reader requires a hollow space on the palm to be swiped on.

The picture you posted shows a UltraNav pad cable on one end, Biometric chip in the middle and the reader on which you would swipe your fingers on at the other. I am not sure if thinkpad T42 and R52 use the same bezel or not.

Newer versions of fingerprint reader for current thinkpads have biometric chip attached to the physical fingerprint which you're seeing in the middle in the picture you posted.
