T430: The problem with shutdown

I have a couple of issues with turning off my lappie.
Don't know yet if this is Cinnamon related, but I can't turn it off thru the regular channel, that is clicking on Quit and them selecting Shutdown.
The lappie simply reboots itself, so in order to actually shut it down I have to click on the "Options gears" and then choose then choose shutdown.

The other problem deals with Suspend, today I had problems suspending it, the lappie simply jumped back to life, just like that. Had to turn it off for good, of course, after it rebooted itself...
