suspend - Ubuntu 16.10 won't wake up after suspending - Ask Ubuntu
i updated 16.10, after suspending computer, can't seem manage wake again, screen black , nothing happens after quick press power button or other button matter. thing seems work hard reboot. read somewhere suspending , hibernating might hardware problem, able suspend before 16.10, seems me problem lies in latest update.
(never tried hibernating before update, doesn't work, might hardware issue instead , i'm not concerned atm.)
another similar question earlier version problem asked pm-suspend.log, sudo lspci -vnn | grep -a12 vga" , "cat /proc/cmdline"
, i'm going attach these here well.

this discovered on 2 computers, 1 ubuntu 14.04 , 16.04. if there drive installed not enabled in cmos settings or if there drive or device missing unit , enabled in cmos ubuntu not recover suspend. have no idea why happens both computers not recover. 1 had sata drive installed , not enabled in cmos while other had optical device enabled not installed. fixing cmos settings in both instances fixed problem.
