[ACPI] question about ACPI & Smart Batteries

[Cintia B. M. <ci...@so...>]

Hello,

I am trying to understand the information flow between a Smart Battery and =
the values
I can see at /proc/acpi/battery/BAT0/state. I lookedt at ACPI standard, and=
 it says
that if the battery supports "smart battery", it is responsible by providin=
g the battery
related values (please correct me if I am wrong). Than I took a look at "Sm=
art Battery"
data standard and it specifies the parameters. It also says that this param=
eters should
be polled by the SMBus Host.

What I really want to know is how often /proc/acpi/battery/BAT0/state is up=
dated when
a battery is discharging/charging.=20

I do not have acpid installed, and I running Debian kernel 2.6.6, with acpi=
 version
20040326.=20
=20
Thanks!
