Red Hat shipped kernels dont include acpi. The -1% for the battery
percentage does look like the laptop may not support much APM if any

ACPI and APM are exclusive but a BIOS can contain both. Its up to the OS
not to try and run both together.

Sean,

ACPI isn't ready for widespread consumption yet.

If you want to help us, check out
http://phobos.fachschaften.tu-muenchen.de/acpi/ and send a proper bug report
to the acpi mailing list.

Regards -- Andy
ACPI maintainer

1. Redhat 9 APM/ACPI problem

I may be imagining this, but I think I remember my ThinkPad T20's power
button doing something clean and graceful under Redhat 8. I'm running
release 9 now, and it no longer does anything (unless I hold it down which
does a hard power off).

That's my main problem. If anybody knows how to fix it using Redhat's
default APM setup and stuff that would be great.

If not, then I need some help with ACPI. I compiled ACPI into my kernel
(the Redhat source, 2.4.20-9) and booted up with apm=off and I end up with
the following errors:

Ps_execute: method failed - \_SB_.PCI0.DOCK._REG (c1ac75a8)
Ps_execute: method failed - \_SB_.PCI0.DOCK._REG (c1ac75a8)
ACPI: Subsystem enable failed

I don't really know what these mean, but I think they're the only messages
signalling something's wrong. Can post the whole dmesg/.config if that
would help.

I'd love to get this sorted if at all possible. Standby works with APM,
and it's really just an aesthetic thing to have the power button working,
but it would be nice all the same. I know ACPI is buggy and incomplete,
it's just I'm sure I had the button working in RH8. Any ideas?

2. Booting on a raid/lvm combination?

3. setting the resume alarm (wakeup from power off) with linux (ATX, APM/ACPI)

4. NexGen, Cyrix MotherBoards

5. APM, ACPI, and Wake on LAN - the bane of my existance

6. redundant ethernet connection

7. APM, ACPI, SMP, and P4's

8. Linux on Compaq Concerto! Anyone?

9. APM, ACPI, and Wake on LAN - the bane of my existance

10. ACPI IRQ routing (was [ACPI] ACPI source release updated (200 11205))

11. Linux ACPI/APM support?

12. APM vs. ACPI status detection
