Thinkpads Forum

I have an x60s. I am using a finger print power on password. Most of the time, it works great. Sometimes, it doesn't recognize that I'm swiping my finger. I try pushing harder, but sometimes I have to do it more than 10 times before it even knows that im swiping my finger, then it says that it was a bad print. If I turn off the machine, and try agian, it seems to work fine. Anyone else have this problem?

YES!!!!! I've wondered why that happens. I usually give up after a few swipes and just use the password. The idea of the fingerprint reader seemed like a cool thing but it's gotten annoying at times. I don't mind if it responds that I didn't swipe right, but it's frustrating to have no response at all to the swipe. I haven't called Lenovo to ask about the issue - I guess it hasn't bothered me enought yet, and my X60s is so new, there's a lot Im still learning (this is my first Thinkpad). If you have any information, I'd love to hear it.

In some situations, it does that.

My hypothesis is that, since it works off of fringe capacitance, it gets calibrated to the settings you enrolled your fingerprint in to begin with. For example, say you are under 60hz Fluorescent lights...then it will have imprinted and save the fringe capacitance of you fingers with a 60Hz interference (ever hooked yourself up to an oscilloscope whilst standing under 60Hz lights? ). When I enrolled myself, it was under fluorescents, and that is when the FPR would work best. It can happen whenever there isRF or NIEMR interference.

I don't think so. The problem happens in the same room, same conditions. If i turn off the laptop and try again, it works.

This is a common problem related to the fingerprint hardware (sensor) and software interoperations, sometimes the inter-/cooperation of the sensor and the controlling software isn't this fast in sync.

You can see this with nearly all fingerprint sensors and their supporting software, no matter if an UPEK or AuthenTec etc. sensor is used in a device.

I found that if I moisten my finger and they swipe it thru, it works everytime (my skip is pretty dry normally).

Just something I found..

I found that one finger works slightly better than the others, so I registered it multiple times (by saying I was registering other fingers). This seems to improve things a lot, presumably because there is a larger database of prints available for recognition.

Hopefully I won't need to put a Band-Aid on that finger any time soon...

I registered two from each hand. I then hurt both my hands and only one registered finger did not have a bandaid no it. Have not had much trouble with any of them logging me in. What I can't gt to work is for the finger print software to fill in password boxes for me in encrypted word documents or providing my password on websites. any suggestions?
