p150hm sudden shut down

Hey guys. Just had an odd experience. I was playing Diablo 3 and all of the sudden my computer completely shut down almost instantly. What could this be?

 

Over heating.

 

^That's what I'd guess.

Are you playing on a soft surface or otherwise blocking the vents in some way?

 

Is it possible that I damaged something?

 

Very unlikely since the only thing you were doing was playing a game. Unscrew the back panel and inspect the cpu fans/gpu fans/heatsinks for dust, loose screws, faulty fans, and check your temps next time you're able to boot up.

You can also reapply thermal paste if temps are high.

 

download temperature monitors from my signature below and post the results on here.
as mentioned it sounds like its shutting down to protect the hardware.

 

This has never happened to me.
BUT....I have taken precautions. Bear in mind the following:
1.) Its summer...its hot.
2.) Diablo 3 does stress the GPU to the max (I guess the game is badly optimized and it sucks out all resources available).
3.) Playing for hours and hours in a room, near the walls, builds up heat behind the machine.

I monitor my GPU temps ever since I first got my laptop. Im using a gadget named GPU Observer 3.7, its free, download it! It shows the temps in the GPU, its clock rate, its fan speed and voltage.
Recently, it began getting hot in my room. 27'C degrees is pretty damn hot. As a result, my GPU temps rose from 80'C under load to the whopping 93'C.

Here is what I did:
1.) Changed places. Moved my laptop + my audio to the 1-st floor in my house, in a cool place next to the living room. Its 22'C here and never gets hotter. My room was on 2-nd floor and is situated to the south-east, so it gets hot as hell there.
2.) Cleaned laptop once again, just to be sure.
3.) Lifted back of the laptop once again with my 2 rubber standers that I made especially for that purpose. I have ~4cm distance between the table and the vent openings underneath the laptop.

Now my machine cools perfectly, 82'C is the maximum temp I have seen since moving to the 1-st floor. Usually it stays 78'C.
Remember, always make sure to be extra careful in the summer. Never place the laptop in a hot room, where you plan to game on it.
For internet browsing, you can do it in hotter places. But when under full load, a mere 5'C temp higher in the room results in 10+ degrees higher in your GPU.
Thats all, lecture is over. Hope there is still somoene alive in there.

 

I have CPUID Monitor running whenever I play any game but from switching in and out every 30 minutes or so the max temp I saw on the GPU was like 85.

 

The GPU is setting itself to Safe mode and results in a shutdown (according to Dell Support)! I had the same issue on my actual laptop (4670 HD Radeon).

 

I'd bet anything it's overheating like these guys said. In addition to monitoring and blowing out the fans, you can limit your fps to 60 so the GPU doesn't work at its max when it hits that ceiling. I have a 485M so I use nvidia's frame rate target but I'm pretty sure D3 has a built-in fps limiter as well.
