Ok, i just updated my kernel to 2.6.13 and now i am getting this message in my laptop battery / power control settings:

"Your computer seems to have a partial ACPI installation. ACPI was probably enabled, but some of the sub-options were not - you need at least 'AC adaptor' and 'control method battery' then rebuild your kernel"

It sounds simple enough... but i dont know how to do it at all. I have been browsing all afternoon and nobody seems to have an answer. A simple walkthrough would be awesome, or at least a step in the right direction. I would not even mind going back to using APM.

I am using Slackware 10.2 on and ibm T30 with kernel 2.6.13

I never tried it on a T30, because I have no T30, but I was successful on many notebooks with the method to build an initial ramdisk with ACPI kernel modules and load it with the kernel before the boot process begins.

Here you find how I did it:

The first part of this post is important, the second part is for cpu frequence scaling.

Fluxx.

yeah, i have seen that you have to recompile the kernel with ACPI built in... but how is that done?

To recompile the kernel is the one way, but I prefer to create an initrd.gz with ACPI kernel-modules. This way I meant when I spoke of the first part of the post ...

Just create an initrd.gz and do the steps I did. I think this may give you success ...

Fluxx.
