ACPI ng: Kernel rebuilt

2.6.21-ARCH kernel
Dell Latitude C400 laptop
Control Center-->Power Control-->Laptop Battery-->Power Control

Your computer seems to have a partial ACPI installation. ACPI was probably enabled, but some of the sub-options were not - you need to enable at least 'AC Adaptor' and 'Control Method Battery' and then rebuild your kernel.

To rebuild the kernel, do I have to start from the ISO and install again from the start?

Is there any other way?

What do I select to have ACPI working?

have you added ac and battery modules in MODULES section rc.conf? if you haven't, then add them and look look at this page: http://wiki.archlinux.org/index.php/ACPI_modules

Does anyone see what is wrong?

Where might  I try other modules?

Re: ACPI ng: Kernel rebuilt

Having multiple "MODULES=" could be problematic.

Try "MODULES=(3c59x mii ac battery button fan)"

Instead of restarting, just execute:

sudo moprobe {mii ac battery button fan}

logout and login back...

Re: ACPI ng: Kernel rebuilt

I changed the rc.conf and battery monitor is working and icon is on task bar.

# modprobe mii worked but:
# modprobe {mii ac battery button fan}
FATAL: Module {mii not found.

# /etc/rc.conf:
Removed these lines MODULES=fan, button, ac, battery

In their place I put in /etc/rc.conf:
MODULES=(3c59x mii ac battery button fan)

Cold booted.

modprobe {mii ac battery button fan} still fails.

But, the battery monitor is working because it's in /etc/rc/conf.

Thanks for your interest and help.

Re: ACPI ng: Kernel rebuilt

got the same problem.

-rw-r--r-- 1 root root 19148 2007-05-06 18:39 video.ko

and rc.conf looks like this for the modules

# Scan hardware and load required modules at bootup
MOD_AUTOLOAD="yes"
# Module Blacklist - modules in this list will never be loaded by udev
MOD_BLACKLIST=()
#
# Modules to load at boot-up (in this order)
#   - prefix a module with a ! to blacklist it
#
MODULES=(e100 eepro100 mii airo ibm_acpi battery ac fan button nvram)
# Scan for LVM volume groups at startup, required if you use LVM
USELVM="no"

i did try the above instructions, and the ones for the modules, it did work with the old kernel though.
cheers,
