ACPI, Mandrake and Compaq Presario 2100

I need some help....

I've loaded Mandrake 9.1 power pack edition on my compaq 2140us laptop. It works...Works Great except for Power management. I can't get ACPI to work. ACPI is turned off by default for MAndrake. I took that line out of the boot arguments and the Computer hangs at "PCI: Using configuration type 1" which leads me to think that possibly it's a bios problem with the laptop except I've seen other posts throughout the internet of people using Suse and Red Hat and getting it to work (or mostly getting it to work....acpi is still sketchy...It would just be nice to be able to monitor battery power while I'm out and about; I've tried to enable apm but the bios apparently doesn't support this). If anyone has any ideas or thoughts I would appreciate it. This laptop has a bios update listed. So if it's that I guess I'm going to have to reload windows to update it...unless someone has a better idea. Sorry for the convoluted question.

I've tried http://linux-on-laptops but nothing. Several models like this have linux with full acpi support. I just can't figure out why mine doesn't.

Randy:

ACPI requires a kernel rebuild. Even then, you may find some things that require tweaking or possibly don't work at all. You can get a pretty good idea what's required by looking at my site:

Even though my site is targetted at the HP ze41xx, you will find a lot of similarity to your hardware.

Good luck.

O.K - It's been a month and I have an answer. I dug into the kernel on mandrake 9.1; tried the updates, etc, etc and I still couldn't get it to work. I bought suse personal edition 8.2 and acpi works fine.
Apparently acpi is either broken in mandrake 9.1 or it just doesn't work on the compaq 2140 - let me rephrase that - Everything works fine except for acpi - so if you laptop never runs off battery mandrake 9.1 works fine (except when the fan cranks up).
My only problem with suse at the time is Im having to use the generic vesa driver for the display. but I can deal with that one. My only last headbanger is wireles I live next to a park with wireles access and I can't get the netgear card up and working.

but anywho - Thanks for the help.

Hi,

I had the same problem with my presario 1400.
I simply added to following in lilo.conf

acpi=on (by default it was acpi=off)

That did it & I did not change anything in the bios.

Thanks,
JP

Acpi support in stock kernels is bad in the 2.4 series. If you need acpi download the kernel sources, patch with the acpi.sf.net package that matches your sources and recompile the kernel after you've configured ACPI support.

Yes, you will not be able to use kernel upgrades from Mandrake anymore since you will be running your custom kernel.

Or you can just wait for 2.6 to be released and hope that Manadrake will package it for use with your distribution.

Anyways, check out acip.sf.net for the details.

Good luck,
Cristi
