Yes, I'm certainly sure you have a smart battery. No smart battery driver support in Linux currently.
*** Bug 3368 has been marked as a duplicate of this bug. ***
Somebody (on acpi-devel@lists.sourceforge.net maillist) is working on a smart battery driver, please wait.
Acer TravelMate 2300LCi seems to have the same problem. DSDT shows no battery device. But if there were a smart battery, shouldn't we see a SBST in the RSDT?

SmartBattery driver from Rich Townsend : http://shayol.bartol.udel.edu/~rhdt/download/acpi_sbs-20050119.tar.gz is able to find smart battery on TravelMate 2303LCi. It requires two functions to be exported from the ec driver (acpi_ec_read and acpi_ec_write). ac_adapter is still missing thow.
Created attachment 8137 [details] SBS drivers These SBS drivers are based of Ducrot Bruno and Rich Townsend drivers, Config: Drivers depend on I2C (Drivers Devices -?? I2C support = Y) These drivers work fine on Acer 2300. I am interested in their behavior on your system. Also: all data in ??/proc/acpi/battery and /proc /acpi/ac_adapter ?? files are updated each minute. I would like to hear your opinion and comments. All ideas and suggestions are wellcome.
