it can be a lithium ion AND a smart battery. those are two different concepts:
- Lithium Ion refers to the chemical technology used by the battery.
- the smart battery refers to the way computers interact with the battery. I think there are two types: smart batteries and some other type which name I can't remember (maybe someone could help me here)

it probably is a smart battery, and yes, it's not at all desirable to not be able to read the charge and AC status, but one can live with it... i do.

to see if it's a smart battery or not, i think you must dissassemble your DSDT and look for something like "Name(_HID. EISAID("PNP0C090"))" or "Name(_HID,"ACPI0001")" or "Name(_HID,"ACPI0002")" [some 
more help here would be appreciated: what is the single line in the dsdt that can tell if one has a smart battery?]. if you find any of those in your dissassembled DSDT, most certainly you have a 
smart battery.

regards,
pedro venda.
