Description of problem: Resuming from suspend-to-ram doesn't work on Thinkpad S1 Yoga. Instead of resuming, the BIOS outputs four cycles of four short beeps, which is a signal for "Replace system board". Power-cycling by long-pressing the power buttons then allows rebooting normally. Version-Release number of selected component (if applicable): $ uname -r 3.17.2-300.fc21.x86_64 How reproducible: Everytime the system is suspended. Steps to Reproduce: 1. Close lid or select Standby from GNOME's menu. 2. Wait for Suspend 3. Resume by opening the lid or pressing any key. Actual results: BIOS beep code, and the LED is continuing to flash like it's suspended. Expected results: Normal resume Additional info: This didn't happen with a F21 nightly ISO from ~mid October 2014.
I just did further test to see when it works and when it doesn't. I freshly installed from the following F21 live images: Fedora-Live-Workstation-x86_64-21-20141016.iso Fedora-Live-Workstation-x86_64-21-20141020.iso Fedora-Live-Workstation-x86_64-21-20141027.iso Fedora-Live-Workstation-x86_64-21_Alpha-1.iso Fedora-Live-Workstation-x86_64-21_Beta-4.iso None of them worked. I then freshly installed Fedora 20 and tested some kernels: 3.17.2-300.fc21 on updated F20 : doesn't work 3.17.0-1.vanilla.mainline.knurd.1.fc20.x86_64 : doesn't work 3.17.2-200.vanilla.stable.knurd.1.fc20.x86_64 : works I then tested vanilla kernels on a new F21 installation, with the following results: 3.17.1-302.fc21.x86_64 : doesn't work 3.17.2-300.fc21.x86_64 : doesn't work 3.17.0-1.vanilla.mainline.knurd.1.fc21.x86_64 : doesn't work 3.17.2-300.vanilla.stable.knurd.1.fc21.x86_64 : doesn't work I don't exactly know what to do with this information, especially since 3.17.1 and 3.17.2-300 don't seem to work, but 3.17.2-200.vanilla.stable does.
I have gotten my Lenovo 440s to suspend and resume without issues just by choosing debugging kernel from Fedora 21 Beta GRUB menu. With regular kernel I get suspend to work but resume fails. Here is a link to my bug report if it helps with additional info: https://bugzilla.redhat.com/show_bug.cgi?id=1162793
I have found the reason why Fedora 21 doesn't resume by default on my Laptop, check out my bugreport to see details. But try installing kernel-modules-extra package and see if that helps. If it does then your laptop is also missing TPM modules and this is the reason why if fails to resume.
