Re: Fingerprint Sensor - Severe and Strange Problem

Hey. Did you figure out the problem eventually??

I developed the same issue since yesterday on my month and a half old W530.

 

Would be really thankful for you to help me out..

Re: X201 Fingerprint Sensor - Severe and Strange Problem

Replaced with success!!

 

In my case the fingerprint lights on the left and right side of the reader works fine but reader could not read anything. Just slow.

 

Replaced the reader card with a used one and it worked instatntly.

 

Looks like the unit can fail. It is not well protected against dirt and moisture so be careful not cleaning the keyboard with anything wet, Or having the slightest drop of water on the reader. Any water will go directly to the reader electronics.

 

The reader device is a BGA (Ball Grid Array) and can easily collect water inbetween reader PCB (Printer Circuit Board) and the device.
