[gentoo-user] no battery state/info in minimal-x86-install-20090526.iso?

[Maxim Wexler]

Hi group,

Just booted into the latest iso on my netbook and first I wanted to
check the battery state:

#cat /proc/acpi/battery/BAT0/state.

No such file. Looked all over /proc/acpi/. Nothing in /var/log/messages.

So I do #modprobe battery but that doesn't do it.

This is an Asus product, so I do #modprobe asus_acpi and get:
FATAL: Error inserting asus_acpi
(/lib/modules/2.6.28-gentoo-r5/kernel/drivers/acpi/asus_acpi.ko): No
such device.

Is there a new way to find out how much charge is left on the battery,
the rate of charge etc?
The charge light is starting to flash so something must be checking it.

Search beneath /sys.
On my thinkpad battery interface went to 
/sys/bus/platform/devices/

That's handled in hardware.

He who laughs last probably made a back-up.

Ok, I see it /sys/bus/acpi/drivers/battery and bind, uevent and
something in pink beneath that but I can't read them "permission
denied. But I'm logged in as root

Well this is the kernle module, drivers are always the wrong choice if 
you want something out of the sysfs. 
and the something in pink ist the link to the device, iirc.

But may you should use a find over the /sys directory searching for BAT 
or acer
