I can confirm the problem it also happens on my T440S. The system will
appear to go to sleep mode (i.e. the LEDs will start indicating sleep
mode). However, it appears to not suspend completely and the system
produces a lot of heat while it is in this state which is rather
dangerous if you put it in your sleeve and leave it there the system
will overheat quickly.
I have updated to the mainline 3.14 kernel and the problem persists.
