Power management, sound, and hotplug problems

[Doug Rohde_1]

I just purchased a zt1180 notebook and am having trouble getting Linux (Mandrake 8.2) working right.

The first problem is power management. The BIOS doesn't seem to support either APM or ACPI. /var/log/dmesg reports:
apm: BIOS not found.

Is the bios in this computer not compatible with APM? If not, is it possible to replace it with an APM-compatible bios?

I'm having the problem with sound and the fact that once you unplug the usb mouse it won't recognize it when plugged back in.

I can confirm all of your problems. I have the same laptop.

I have an ongoing discussion about this at omnibook@zurich.ai.mit.edu with many other zt series owners. You can also check out my web page for updates at www.dyll.com

Search the achive for zt1000 or my name and you will see the thread.

This is a know problem but it seems that no one in HP is involved or helping yet.

In installed Mandrake 8.2 on a Omnibook XE3L and I have the same problem with APM.

the bioses of these new laptops don't use APM, but ACPI instead. As of now ACPI doesn't work either. The bios is missing on some tables, which the kernel tries to load and thus fails. For more information look at

and the links therein

Regarding the sound, using the lastest alsa drivers 0.9.0beta 12 sound works with xmms and mplayer. But not with aplay or wavplay.
Using XFree 4.2.0 I have no problems with a usb mouse.
I think having the latest kernel and XFree really is of importance. My PCMCIA port is correctly identified in the 2.4.18 only. Previous kernels won't do.
