That sucks, I do hope it won't be anything too bad and it will be resolved quickly.
Why is it that I see this issue happen to so many developers or artists?
Fingers crossed, good wind
I don't know it was bugging me three month ago but at that time it didn't happened when it was on charging. Later after few days the issue was completely gone and now it is back freezing the system even if it is left idle. I still tried resolve it on my end by resetting PC, updating drivers but that didn't work. I was little hesitant because of my data but submitted the laptop anyway as it was the last resort.
I too hope it will be resolved quickly.
