Alexander Diaz4 said:"What if this, what if that..."—by the time you make up your mind, your warranty will be gone. You said yourself you've still got a month left; that month's gonna fly by, and then what?
You say it's not your job to troubleshoot, yet here you are, diving headfirst into diagnosing and guessing what's wrong instead of just heading straight to the service center or wherever you bought it to talk to the professionals whose actual job it is. You came to a forum to vent instead of dealing with it.
Look, if you actually needed this laptop for work—if your livelihood depended on it—you'd know exactly what to do right now. You wouldn't even be posting this here. You'd just file the claim, grit your teeth, deal with not gaming for a month, and move on.
And as for it being "practically new" after 11 months... well, we could go back and forth on that all day.
Well, of course I started troubleshooting... within reason and based on my own limited skill set. I'm not some lazy guy who's going to sprint to the repair shop the second a machine acts up without checking if there's something I can fix myself first...
The reality is that the issues kicked in once I started gaming through an external monitor with the laptop lid closed. That's when those random shutdowns during gaming sessions began. After doing some digging and thinking it through, I realized the setup was blocking the GPU from cooling properly through the keyboard area. I rearranged my gear so the laptop stays open while I'm gaming, and it seemed like the problem was solved.
I also installed a utility to monitor GPU temps and fan speeds because I had my doubts about whether they were even spinning correctly.
Then I reinstalled all the drivers.
Then I ran the built-in self-diagnostic tools...
etc.
Anyway, after all that work, it looks like the issue is still lingering, even if it's slightly less frequent now.
