HP does this, and it is not for sure that the calculator goes to sleep before running a poll vector.

I have never run into an issue with the current status (i.e. without the additional "assurance" on the secondary banks) - not on V41, i41CX, all the standard machines, and of course the CL. I too was under the impression that the Cold Start or deep sleep will do that as well, but yes I've seen that done on the 41 Advantage - maybe due to the type of chip they used for that module?

Moreover, all throughout the code there are numerous locations where I haven't been all that rigorous switching back to the main bank - like after an error condition (Data Error, NonExistent, OutOfRange). This doesn't seem to have an adverse effect, the machine is back to the main bank regardless - which should confirm the Deep Sleep assumption.
