Oops, I meant the Fn key. Let's try this again. As a capacitive sensor, when the environment changes, the capacitive touchpad will need recalibration. The B2 and before touchpads do not auto-calibrate. 1) if you have your finger on the touchpad during power-on, you can cause problems. 2) the calibration may shift when you go to/from battery power, or after resuming from suspend (not yet deployed).
To force a recalibration of the touchpad, you perform what we call the "four finger salute". To recalibrate, press all four keys at the corners of the keyboard at the same time, pressing the "fn" key last, while keeping your fingers off the touchpad. BTest-3 and beyond will automatically recalibrate. We received samples of the BTest-3 touchpads late last week, and have installed several, and are happy so far with their behavior. Remember: please leave the (slightly off color) plastic sheet on the touchpad; it does make the touchpads work much better.
