LID button Event ACPI malfunction

LID button Event ACPI malfunction

[Benedek Frank]

Hi

When I shut down, my machine (Dell 700m) goes into suspend to ram twice. I 
have to wake it 
up, and it goes further, sleeps again, wake it up, and finally shuts down. I 
just had ACPI worked out (kernel 2.6.9), and since just recently I can go to 
suspend to RAM 
and DISK as well. Now, why a shut down triggers a suspend-to-ram?

When I look at the LID button under ACPI

/proc/acpi/button/lid/LID0/state

it says 

state: closed

It is clearly not closed, as I am looking at the screen. :)

I have an ACPI event that gets triggered when I REALLY close the lid, and that 
works.

Here is the event

/etc/acpi/event/lidbtn

event=button/lid
action=/etc/acpi/lidbtn.sh

And here is the script

/etc/acpi/lidbtn.sh

#!/bin/sh
/sbin/sleep

And finally here is /sbin/sleep, that was written by me for the machine's 
special needs (like module unloading, video_post etc.)

rmmod b44
echo "mem" > /sys/power/state
#echo 3 > /proc/acpi/sleep
modprobe i830
/root/emu/video_post
modprobe b44
/etc/init.d/networking restart

Thanks for any help

Ben

RE: LID button Event ACPI malfunction

[Li, Shaohua]

I guess the system invokes ACPI event when shut down. If the button
driver provides a .shutdown method, the issue could be fixed.
Actually in recent discussion, we agreed every ACPI driver should
provide .shutdown/.suspend/.resume method, but we must migrate to sysfs
interface for ACPI and use generic device model first.

Thanks,
Shaohua
