60 ° Celsius? 😮 Where do you live?Happened to me too. Rested on my lap on with blanket in between. Casually browsing the internet. Far from anything that would tax the processor. After about an hour, when I lifted it up, realized condensation had settled on the bottom. Temperature inside my home was in the high 60’s at the time. Haven’t been able to replicate the issue on a hard surface.
