Sims 4 making laptop go to sleep

DecayingShiggy​  That is strange, and you shouldn't need to turn down the graphics at all.  But the thermal event is concerning.  Do you have any more information on which component is triggering the error?  Have you ever run a stress test on the laptop to see how it handles a maximum CPU or GPU load?  If not, and you're interested but don't know where to start, just ask.

And to be clear, the laptop is going into sleep mode but not shutting down?  As in, you can wake it back up again and you're back into the same session, with Sims 4 and everything else still open?
