I have received brand new Dell Latitude E7470 with preinstalled Windows. I have reinstalled the system with Ubuntu 16.04.2 from flash, formatting the entire hard drive along the way.
I have experienced the same problem. When suspended on power and waked up on power it worked. When I unplugged the power cable while suspended it rebooted. When suspended on battery it always rebooted. I have enabled hibernate as described above. Hibernated several times by different means (lid, menu button, shell command) in different states (powered, on battery, plugged and unplugged cable while hibernated) and suspend works now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1661741 Title: [Dell Inc.
