Re-calibrating Prime's Battery?

[rprosperi]

Yes, the 41 and 71B use the same power adapter. In US, the model is 82059A/B/D or 82040A, the UK flavors are 82067A/B. Unlike most of the previous adapters, this same adapter is used for many HP machines and accessories: 41, 71B, 75C/D, 19C, 97/91/92, IL Printer, IL Tape Drive, IL Interfaces, TopCat battery charger and others.

For the 41, I do the same thing, keeping a spare (actually 3 spare) 41 battery holders, loaded with N cells, ready to swap into a 41 when needed. When changing batteries on a 41CL, I've never lost data, however the first couple times I thought the CL configuration had been lost, and was not sure why. In actuality, all config info had been retained but the MMU had simply been disabled by the battery swap, so a simple MMUEN command restores everything immediately.
