After so much waiting, I finally got my replacement 2740 with an SSD and been loving it, only to find that the fingerprint reader is problematic. I have had a lot of HP machines with FP readers and really know how to swipe them to enroll and use them, but it's been taking 50-75 swipes to get a fingerprint enrolled, and then of course it almost never works to log on, because it's so fussy. I'm afraid this is a hardware problem - either a bad sensor or the sensor is misaligned with the opening on the side, meaning sending back for a replacement (there is still time in my 30 days on the new one) seems the only solution. Anyone know of a software solution to mis-calibration of the FP reader? I so don't want to send this one back! Thanks.
