Description of problem: This is for the 2014 version of the Thinkpad X1 Carbon Touch, the one with the adaptive keystrip. When sleeping or hibernating for any reason (lid closed, command line, gnome menu, timeout), laptop appears to go to sleep, but cannot be woken up. Screen goes black, fans stop, power light starts slow blinking as typical for sleep. Opening the lid, hitting keys or mouse, or pushing the power button do not wake the computer. The power light continues to slow blink. The only thing that breaks the laptop out of this state is holding the power button until hard poweroff. After booting again the laptop is fine. Sleeping from windows works, so this isn't faulty hardware. One thing that is strange is that the adaptive keystrip never powers off during sleep. When sleeping from windows the keystrip goes blank. Nothing in dmesg or journalctl seems to show anything going wrong, here is the log from when it goes to sleep to the next boot: May 04 12:35:30 localhost.localdomain systemd-logind[677]: Power key pressed.

Sleep via command line, menu or lid close 2. Attempt to wake with power button Actual results: Nothing happens. Expected results: Laptop should wake up. Additional info:
I've found that updating to the latest BIOS (1.14 in my case, but I think the problem was fixed in 1.13) seems to have fixed the problem, and I have no problems suspending or unsuspending any more. (Also note that if you try to download the bootable ISO image from Lenovo's website, there's a typo in the filename and you'll get a "File not found" error. Look at the file name for the .exe version, and change the ".exe" to be ".iso" and that should work for you.)
The BIOS update fixed it completely. Thanks! I guess this is not a bug then
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
