I have a Compaq Presario V2000 notebook PC running a 1.8 GHz Turion 64 processor, 512 MB ram, with an ATI Radeon XPRESS 200M (shared memory). I am running Kernel version 2.4.31 with Slackware 10.2. (Anymore information you need, let me know please.)

My issue is with ACPI.

And before anyone asks, my kernel is compiled with APM support as a module and ACPI support in the kernel.

Now, I am able to run /sbin/acpid and the like, but like with all laptops I really need to see my battery level, so the problem lies in the fact that there seems to be no /proc/acpi/battery.

I have compiled everything into the kernel and not as modules (I am making everything a module now). Also, I am pretty much a newb on ACPI and APM, so I was wondering what it is I am doing wrong? Or rather, what does one need to know/understand in order to get it working correctly? Thank you for your input!

i had this problem. i never really got a solution for this. i hope u get it. i solved my problem by switching to a different distro. but ofcourse iam not recommending it.

take alook at http://www.linuxquestions.org/linux/...sario_Notebook
It discusses kernel setting for acpi and apm that may help.

The lack of responses are an indicator on how well known this topic really is... None-the-less, I have come up with a solution.

Following this guide: http://www.linuxquestions.org/linux/...sario_Notebook

I noticed very quickly that the instructions don't mesh nicely with my platform, however all I did was this:

Processor type and features
---------------------------
Processor family: from 'i586' to 'amd64/opteron/k8'
Local APIC support on uniprocessors: from 'y' to 'n'
...
further down this guide are things regarding hotplug support -- I don't think this has anything to do with ACPI, so I didn't touch it.
...
General setup
-------------
Advanced power management BIOS support: from 'm' to 'n' #In my opinion, this was the kicker
ACPI support
------------ #These options were already done
AC adapter: from 'm' to 'y'
Battery: from 'm' to 'y'
Button: from 'm' to 'y'
Fan: from 'm' to 'y'
Processor: from 'm' to 'y'
Thermal Zone: from 'm' to 'y'
Toshiba laptop extras: from 'm' to 'n'

So I guess the lesson to be learned here is, if you want ACPI, don't have APM enabled -- at all. I don't know if changing my processor type had anything to do with whether or not ACPI works now, but I changed it regardless.

I don't, however, have processor throttling enabled, so that will be my next task. Maybe I need to enable APIC (Advanced Programmable Interface Controller)? We'll see. I also got a nice shell script from the web that shows my battery level in the console, I will post it later while in Discrete Math

Thanks yall!

Errrmmm.....I think it states that in the info for ACPI when you configure the kernel. That's why APM is deprecated
