I previously used 14.04 and i used to suspend when ever i am done and need to resume my task later . That shuts my machine down(except the LED indicator) which didn't consume power and no heating so i could put my lappy in bag causing no heating problem and whenever i turned it on it resumed to my previous state….(All was OK till then.)
But now in 16.04 it is not shutting down after suspend or hibernate only screen is getting shut but backlights are still on and this state consume battery and i can not put my lappy in bag cause it gets overheated.
And i cant even turn it on to make a proper shut down(In this case i need to do a force shut-down /long press power buton)
How can i have the same functionality like i had in 14.04
Hibernating without heating(power consumption).

check if you have installed your proprietory graphics drivers (dash -> software and updates -> additional drivers). if it still doesnt work, check https://wiki.debian.org/Suspend link and troubleshoot to find the problem (kernel testing facility). hope it helps.
