I've installed Ubuntu 16.04 on my Lenovo Yoga 2 13 (not pro) and almost everything is working out of the box, however I'm experiencing a single issue that unfortunately is a deal-breaker for me: sometimes the computer does not wake up from suspend.
I tried to suspend by both closing the lid or by entering pm-suspend, however the result is the same. Most of the times it suspends and resume correctly, but sometimes (maybe once a day) when I open the lid the keyboard (which has backlight) lights up and the fan starts to spin (as normal when resuming) but the screen says completely black. I tried shortcuts to drop to console mode but with no success... the only thing I can do is to force shutdown by keeping power button pressed. The issue seems to be random, I'm not able to reproduce it (for instance it does not depend on the amount of time the computer has been sleeping, but it seems to happen more frequently when on battery power).
Previously I tried with older versions such as 14.04, 15.04, 15.10 and even Fedora 22 and 23 but the issue persists, so it is not linked to a specific version. My Yoga 2 13 has i3 processor, 4GB of RAM, 256GB SSD, Intel 7260 WIFI and Intel HD 4000 graphics.
With Windows 10 this does not happen. Someone advises to turn off USB3 in BIOS but I found no such option for my model, in other cases (with other laptops) the issue was solved by Lenovo with new specific BIOS updates (I'm using the lastest 1.17).
Does anyone have any suggestion? Thank you!
