I received a 'new' manufacturer refurbished laptop from Microsoft a few days ago. Yesterday I ran into an issue with the laptop entering hibernate mode in the middle of my playing games without warning. An error message of some sort came up at least once when this happened, but the computer hibernated too fast for me to read the message.
Given that it's new with almost no software on the computer to cause conflicts, and was refurbished, I'm strongly inclined to believe the issue is due to hardware. However, before I demand a replacement I was hoping to narrow down to the exact hardware issue so I can better express what is wrong.
I tried checking my event logs and none of the error messages I saw after a shutdown appear to be relevant. There is a generic error message about an 'exception' (no details) From Heroes Of the Storm, the game I was playing at the time of the shutdowns; but it doesn't provide anything useful and I'm assuming it was caused by the hibernation happening mid game, rather then the cause of the computer hibernating.
My current presumption is that the computer is overheating. This is because I played hours yesterday without issue of a different game, Paladins. Also I was able to play a decent amount of Heroes Of The Storm before the first hibernation occurred, but afterwards if I turned the computer back on It would hibernate within one game (less then 20 minutes). This suggests to me the hibernation isn't completely random, the idea of overheating leading to it would explain why it only happened after serious playing of one game (assuming HoTS is producing more heat then Paladins). The spontaneous hibernation issues persisted across a reboot.
What can I look for to provide definitive proof of this issue, such that I can provide evidence that the provided laptop is defective and demand a replacement? Is there a specific event I should be looking for in the event logs I may have missed? Surely a shutdown due to overheating would be recorded somehow? Is there a different hardware issue I should investigate as the cause of the random hibernation events?
edit: While downloading some software to monitor system temp tonight the computer went into hibernate mode. I hadn't done anything resource intensive prior to this, which suggests that overheating isn't the issue.
Also I forgot to add it to my original message, but the built in hardware scan found nothing.
