Linux (RH9) Evo800c Notebook and port replicator issue...

Andrew Bruce — Fri, 09 May 2003 11:48:42 GMT

Hi,

I have Redhat 9.0 (2.4.20-9) installed on an Evo 800c notebook. It works fine with the exception of two problems:

1. Most important - docking into the port replicator is broken - the mouse, keyboard, and monitor connected to the port replicator won't work - any fix for this?

2. The battery is not detected by the APMD. If I unplug AC power, APMD thinks I have -1% battery power remaining!!!

Hi

I have installed Mandrake 9.1 on an EvoN800c and the port replicatior works fine! I think this does not depend on the software wich is installed. If it does not work, its mainly a hardware fault!

The only problem i have is the ACPI/APM. None of this work correctly...

Power management on newer notebooks requires ACPI. The kernel shipped with RH 9.0 is not configured for ACPI. To get working ACPI, you need to build a kernel (after patching with an appropriate patch obtained from the ACPI project on SourceForge).

Thanks for the replies (points still to come):

I know the port replicator problem is not hardware - it works fine under win2k (my laptop is dual boot (though I don't think that has any bearing on the problem)).

Under Mandrake, did your port replicator get recognised as additional hardware (device)? Or is the functionaility entirely transparant?

WRT ACPI - I already built a kernel including ACPI, but that didn't helo either. I had a look for an ACPI deamon but didn't manage to find anything resembling a working solution.

Can anyone recommend an ACPI deamon, and is there any other software I should be looking at?

Thanks again...

There are a couple of important aspects of ACPI to be aware of:

1) Most users find the ACPI support built into 2.4 kernels unsatisfactory. It is important to use the ACPI project patches.

2) ACPI is mediated through the bios. As a result, different ACPI features are available on different hardware, depending on what the manufacturer implemented. Also this means that the names of /proc/acpi subdirectories and files vary from one computer to another. So in many scripts or programs written for ACPI, it is necessary to adjust the ACPI file/directory names in order to get things to work.

3) Things like software suspend (which is actually code separate from ACPI) often don't work very well on particular hardware.

I use acpid as a daemon and gkrellm with an acpi plugin for monitoring battery and temperature. You can find more details on my ze4100 site:
