Lenovo X200 can not suspend

[Mike Klein]

Binary package hint: acpi-support

The Lenovo X200 does not seem to support suspend-to-ram. How can I help you fix that?

I'm running the latest x64 Intrepid.

I can confirm on Samsung X30. After downgrading the "Suspend" option becomes available again.

Oops, wrong bug. I wanted to confirm bug #267141.

I can confirm this on my lenovo X200 too. The suspend option does not appear at all. neither does the suspend key work. sudo pm-suspend does nothing, and produces no logs in /var/log/pm-suspend. Hibernate works.

I'll be glad to provide any debugging info that you might need.

oh, and to add: I too am on x64 intrepid.

this might be an hal issue, I really don't know. My hal says power_management.can_suspend = False. I tried setting it to True manually, and gnome-power-manager seems to recognize that I can suspend, but nothing really happens when I try to suspend. "sudo pm-suspend" still doesn't work, and still doesn't generate any useful logs.

more info:

# cat /sys/power/state
mem disk
# echo mem > /sys/power/state

and the system goes into suspend state. Of course, it became unstable on restoring. Maybe (again, I'm not an expert) this means that ACPI is not at fault, and hal is at fault?

I would also like to point out that "pm-is-supported --suspend" returns non-zero, (I noticed some hal code running this command, which seemed like the only like hal code that could make this value false), so maybe this is a pm-utils issue?
