Talk:How to make ACPI work
Contents
X41 Woes
I have tried the referred patch (Suspend to RAM) with the latest stable kernel (2.6.12.2): Reboot after wakeup.
T22 Woes
Has anyone managed to get this working with a T22? The BIOS is upgraded, but it _never_ wakes up from sleep. Neither lid nor pwr button are noticed by the system.
--Are you in suspend2ram? This works fine for me. I think you have to enable it in BIOS.
Sound-after-suspend not working with Mandriva 2006
With Mandriva 2006, suspend/resume works with ACPI, but sound quits working. This happens with the T20 and T22. The recommended Mandriva trick of setting "RESTORE_SOUND=yes" in the "suspend" script doesn't solve this. Other suggestions? - MarkStosberg mark@summersault.com
Solutions
I had 2 different issues: - with my X21 I had to unload the alsa modules before suspend. - with my x23 I have to change the mixer settings to get it working again.
(I hope it will help)
CIFS
Hi all,
I have found out that if I use cifs to mount Samba shares, I get lots of problems with suspend/hibernate (the cifsd breaks the shutdown process). Maybe it would be good to warn about this.

Auto-wake on lid open - how to STOP?
Anybody have any idea how to stop the machine (a T43p) from automatically waking up on lid open? My /etc/acpi/events only has a lm_lid file which is commented out - it should do nothing, and there is no plain 'lid' event. Is lm_lid an event only activated when in laptop-mode?
That's a good question, but I have the opposite problem: my T43 (2687) won't wakeup from S3 (suspend-to-RAM) when I open the lid, which is exactly what yours do, and what I wanted mine to.

Yes, I have the same problem - this 'feature' is exhibited in both O/S's on my T43p... I tried everything I could think of to stop it (changing/deleting the acpi event handlers, etc). There does not seem to be any BIOS option to "wake up on lid open."
It has irritated me less over time; I find myself now using suspend if I don't want the feature, and sleep mode only if I anticipate that I will open it up and use. After all, suspend is pretty quick with 1 GB ram.

Just a note...the term "suspend" refers to both, suspending to RAM and suspending to disk, the counterpart to the "sleep" term is "hibernate". We should try to stay clear about this everywhere to avoid confusion.

There is a /proc/acpi/wakeup file here. (t42p). Currently shows: Device Sleep state Status
LID 3 * enabled SLPB 3 * enabled PCI0 3 disabled UART 3 disabled PCI1 4 disabled USB0 3 disabled USB1 3 disabled AC9M 4 disabled
Echoing the 4 letter code toggles that device as a wakeup device.. ie: root# echo " LID" > /proc/acpi/wakeup root# cat /proc/acpi/wakeup Device Sleep state Status
LID 3 *disabled
Does that work for any of you guys? Nirik 23:15, 29 Mar 2006 (MST)
