Hi, Randy, folks...
In many situations like this one I recomend keeping batteries in place and BRIEFLY shorten their poles. I read soem sutff about it and I think there is some reason on it.
As voltage suppliers, batteries have low internal resistance, so if you touch one pole and you have electrostatic charges, both poles will be equaly charged because batteries are an easy, low-resistance way to connect them. In other hands, if you touch one pole a tenth of a second before connecting to the other and there is electrostatic charges in your finger (or whatever instrument you have used to connect them), chances are that if ESD occurs the calculator will remain in the same "resting" state.
The user's manual for all Voyagers suggests the same: keep batteries in place and briefly shorten their terminals. As they are in place, both batteries and calculator terminals are the same, right Paul? Also, after this discharging procedure, try [ON] and [yx] keys in the same time. Sometimes this procedure "wakens them up".
Just my US$0.01.
