I installed Fedora 20 on my new ThinkPad X1 Carbon (2014). I am currently using the 3.13.8-200.fc20.x86_64 kernel. I am using GNOME 3.12 from http://copr.fedoraproject.org/coprs/rhughes/f20-gnome-3-12/ to get at least some support for HiDPI.
Suspend (triggered by closing the laptop or by "sudo pm-suspend") seems to work but resuming from it does not work. I have to power off and back on.
Hibernate (triggered with "sudo pm-hibernate") works. Resuming from hibernation works as well. As a workaround, I would be happy if the laptop would hibernate instead of suspend when I close it. How would I configure that?
I was having the same issue, after updating the bios resuming now works.
"(Fix) Fixed an issue where the computer might not resume normal operation from
sleep state on Linux."
Thank you, Andrew, for sharing that information. I just updated the BIOS and can confirm that this solves the issue.
@Sebastian; glad to help!
Reopening and assigning to me because if it works in Windows, it should work in Linux. No promises that I'll figure out what the problem is, though.
Update: The adaptive keyboard (see also https://bugzilla.redhat.com/show_bug.cgi?id=1078455) is turned off after resume rendering it completely unusable (no F keys) until the next reboot.
It does however work after waking up from hibernation.
So I have a variation on this. My new X1 Carbon (BIOS 1.16) will suspend and resume fine with F20. But the F21 almost-alpha fails. It will suspend and I get the blinking power button, but nothing happens upon pressing that button. I have to hold it down until things power off entirely and start over.
All the various pm_test modes work fine. I've installed the F20 kernel on the F21 alpha, and that fails to resume, so the kernel itself doesn't seem to be the problem, somehow.
Thoughts? Anything else I should try?
Is this on a Lenovo X1 Carbon gen2 / 20A8 i have the same problem here on F21.
F20 could suspend and resume without a problem.
I use BIOS 1.16 on the update to 1.17 did not work

*********** MASS BUG UPDATE **************
We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs.
Fedora 20 has now been rebased to 3.17.2-200.fc20. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
If you have moved on to Fedora 21, and are still experiencing this issue, please change the version to Fedora 21.
If you experience different issues, please open a new bug report for those.
This bug is being closed with INSUFFICIENT_DATA as there has not been a response in over 3 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously.
FWIW, this problem is solved in F21 by including the tpm module at boot or disabling the TPM in the BIOS. So all should be well here.
