Touchpad won't work.

Use a small torx or if none available, a small screwdriver to gently remove the two screws on the back of the unit. Gently pry the sides away from the back. Open the unit carefully. Remove the two screws securing the system board to the back of the Zire. Gently open( like a book) the boards and screens. Once I did that I turned the Zire on using the switch that is only a small bump on the sytem board. After a gentle tap pr two the touchpad bagan working again. Carefully reassemble the unit and hope it lasts another while. Just in case, do a Hotsync so that your data is saved should this "adjustment" fail to solve your problem.
