Pavilion zt1290, power problems
I've been running SuSE linux (currently version 9.0, kernel 2.4.21-215-default) on my zt1290 for almost 2 years now without many problems. However, for the last 3 months or so I've had a bad problem which prevents me from removing or connecting the AC adaptor. If I remove the AC adaptor, the laptop locks-up hard. Nothing recovers it, only power-cycle. I also cannot find anything in the logs about what happens just at the AC disconnect. The only message I have that might at all be related comes during booting:
May 28 13:12:23 wunjo kernel: ACPI-0165: *** Warning: The ACPI AML in your computer contains errors, please nag the manufacturer to correct it.
May 28 13:12:23 wunjo kernel: ACPI-0168: *** Warning: Allowing relaxed access to fields; turn on CONFIG_ACPI_DEBUG for details.
If I use acpi=off as a kernel boot parameter I don't have this (lock-up) problem, but then other things don't work properly because I need the ACPI PCI routing. Sorry, I don't know what other details to give since I'm pretty ignorant when it comes to ACPI. If I missed anything just ask me. Any help is greatly appreciated.

Re: Pavilion zt1290, power problems
Thanks for the input. I am using the lateest BIOS that I'm able to find (ID.M1.05 released 9/23/2002), so it looks like I'll have to get in touch with customer support.
Cheers,
Richard

Re: Pavilion zt1290, power problems
Thanks for you suggestion. I tried "nolapic" (though I thought this was only introduced in 2.6 kernels) and I also tried just plain "noapic". Unfortunately, neither one helped. I did contact customer support and after exchanging a few e-mails I was told my message had been forwarded to the appropriate department. I'm hope that doesn't mean I will never hear back from them. I'm still open for suggestions. :)
Cheers,
Richard

Re: Pavilion zt1290, power problems
Unfortunately it didn't solve my problem. However, I did findout that if I turn off both acpi and apm (kernel parameters acpi=off and apm=off) I do not have the above described problem with connecting/disconnecting the AC power. So that says it is definitely a software problem and not something wrong with my hardware (as I was beginning to fear). I guess I'll live with it like this for now. Of course I'm still open to suggestions on how to debug the real problem.
Cheers
