The code to allow ACPI to add batteries has yet to be written (or committed, at least). If the system is booted with 2two batteries, both will be seen. Even it one is removed and then returned, it will be seen. But if a system is booted with a single battery, ACPI will not ever see the second battery. Please note that the second battery WILL be seen by the hardware and both charged and used. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
