acpicmp dump

here is the dump from acpidmp, its 80mb

Comment 3 Shaohua 2004-11-14 16:56:24 UTC

Yes, I'm certainly sure you have a smart battery. No smart battery driver 
support in Linux currently.

Somebody (on acpi-devel@lists.sourceforge.net maillist) is working on a smart 
battery driver, please wait.

Comment 6 Vladimir Lebedev 2005-02-03 03:48:04 UTC

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.

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.
