I did a fresh install of Ubuntu Gnome 16.04.
When booting up it shows the logo and it goes into suspend.
How do I find the issue and fix it?
I think I had almost the same issue after upgrading fom 14.04 on an older SAMSUNG laptop. Even booting from an install media (CD) did not work: The laptop went into suspend or hybernate mode every 10sec.
After booting from an 14.04 install media I could change HandleSuspendKey and HandleLidSwitch to ignore in /etc/systemd/logind.conf. This solved my problem. See: https://bbs.archlinux.org/viewtopic.php?id=178047
