bug#22759: Sleep function will not work again

[Noe]

I sleep my computer for faster access when unexpected things pop up on 
my schedule. I use Linux Mint 17.3 Rosa MATE 64-bit for every day use 
like web browsing and heavy gaming and when I sleep the compute it does 
what its suppose to do. It was working well in the beginning when I 
installed but then stopped working after a while of updates and stuff. 
Function and Sleep button do not operate on the system for some reason 
but do work cause I also use Windows 7. Could this be a bug or can I 
resolve this by myself?

Thanks, please get back.
