Intrepid: resume after suspend inconsistent behaviour on Thinkpad

[Andreas Jonsson]

I can suspend my Lenovo Thinkpad T61, either using Suspend from the the Power Manager Applet or the Fn+F4 key. However, only in the former case does the laptop resume properly. When I use Fn+F4 the resume initiates, the drive starts running and the screen comes on for about half a second, and then it falls back into suspended mode. Now, if a try to resume it a again, it works. How can I make resume work flawlessly with the Fn+F4 button?

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information.

Please include the information requested at https://wiki.ubuntu.com/DebuggingHardwareDetection as separate attachments.

I have assigned this to the linux kernel team as it seems to be improper response to the hardware keypress.

Thanks for your supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

I'm facing the same problem on a Lenovo X61 tablet.

Same problem on a T40p. Suspend by closing/opening the lid works just fine but Fn-F4 exhibits this weird "bounce" behavior.

I am experiencing the same issues on a Thinkpad x31. Please let me know if I can provide any more information.

This thread might be useful to anyone looking into the issue... http://bbs.archlinux.org/viewtopic.php?id=58129 It seems they've solved it. Has anyone else tried this? I'm not sure if this is what's wrong in Ubuntu, and I'm not sure how to fix it if it is.

I've had the same issue and can upload information files if someone thinks they'll be helpful. I don't have Ubuntu running on my laptop right now, but will help out if needed.
