Hello all!I have DSL 2.4 installed on my Compaq Armada E500. It runs wonderfull!
But I've been trying to enable the battery state with acpi or apm.
As I found in the DSL forums DSL version 2.4 do not support acpi. Is that right?
I wonder if is there any way to check the battery, cpu temperature with apm or acpi without updating to a DSL newer version. Somebody got apm or acpi working on those DSL 2.X? I would appreciate a lot any piece of advice.
Thanks in advance,
Matías

It depends whether your laptop BIOS supports APM or the newer ACPI - I was using ACPI with DSL 2.x and a Dell Latitude D400.If I recall correctly (I made several posts on the subject), I had to use ACPI=force APM=off as boot cheat codes. Once booted, you will need to "modprobe" the ACPI ac, battery, button, fan, processor and thermal modules which are already in DSL 2.x
Once you have done the above, you can read the battery state using the dockapp wmacpi_1.99r7.dsl or you can manually do it by using the command:
cat /proc/acpi/battery/BAT0/state

Thanks for your help! 
Hs7v, I had read your threads before and I followed your recommendations. Unfortunatly It didn't work for me.
As I read on Armada e500 user manual she supports acpi.
I tried changing my grub's menu.lst with apm=off acmpi=force
But after that, when I try doing sudo modprobe battery (and the rest) dsl seems not to find the module.
I wonder if the kernel may need some patch... But as I'm new to linux, may be the easiest thing to do is changing to a newer dsl version. I have DSL install on my hd.
What do you think about it? Do you know why is not possible to load the acpi (battery, fan, processor, etc) modules? I tried it why dsl 3.1 live cd and that seems to work.
Regards,
Matías

DSL-2.4 (kernel 2.4.26) doesn't support ACPI. Please try DSL-2.1b (kernel 2.4.31). It works on my Laptop.
