Same for me with a Lenovo W510 in dock, two external monitors and Ubuntu GNOME 16.04 LTS.
After waking up my notebook two or three times I am finally able to login via GDM and use my system as normal, but as soon as I switch to one of the ttys my laptop suspends again.
Btw: I don't know if this is relevant, but for the sake of completeness I want to mention that hwinfo --monitors gives no output at all!
