UPDATE 2: when CPU MAX = 100% and GPU °C > 85 (tested with GPU-Z) my DV6 freeze.

Re: Probook 6540b shuts down while playing a game

UPDATE 3.

 

It's not a problem of gpu temp: it's a problem of CPU temp. When CPU Temp goes up to 75-80°, the pc freeze (tested with speedfan and coretemp).

 

Three possible cause:

 

1. silicone thermal cpu paste is finished;

 

2. videocard damage;

 

3. some other heat hardware problem (fan, heat sink, etc.)

It seems it has already helped few people. you can change the FAN speed there. I have tried it already. works fine.

Re: Probook 6540b shuts down while playing a game

I think I figured out what may be the cause of our grief. It's may not be a hardware issue at all, but rather a design flaw. The air intake for the graphics card is located underneath the machine, but the machine is not raised enough from the surface to let in sufficient air.

 

I was at a LAN last night, and of course crashed after five minutes. One of my tech-savvy friends suggested I tried putting it on his laptop stand, elevating it from the surface. That did the trick, I was able to play on with no trouble, and it did not get very hot. It crashed only once, after about six hours of gameplay.

 

Turns out another of my friends have had the exact same problem (with a different laptop). He bought a laptop stand, and lived happily ever after. Before I make any new investments, I shall try to make more room for the air intake by elevating the machine, somehow.

Re: Probook 6540b shuts down while playing a game

I wish it could be so simple... BUT that's not the case, my case... My crap was always on a ventilated stand but that didn't do the trick. It crashes completely random, sometimes after 5 minutes, sometimes after hours, sometimes it doesn't crash at all...

Re: Probook 6540b shuts down while playing a game

Alas, you are right, azmo. I had bought an old game called "Evil Genius" (2004), but even while having the craptop on a makeshift stand, it crashed. Well, there goes that theory.

 

The thing that continues to baffle me, is that it doesn't matter if it's a new and demanding game, or some ten year old classic, it still crashes if there's 3D graphics involved.

[ Edited ]

UPDATE 4: I changed the silicone paste on CPU and GPU some days ago, but the PC still freeze-lock-shut down. So, it isn't a problem of paste...

 

SO, since Crysis 2 now freeze at low temperature (60-70), and only in particular condition-levels-effects, I think may be a problem of 3D card damage.

 

EDIT: WHERE THE HELL IS HP?? MAY SOMEONE HELP US...THANKS!

Re: Probook 6540b shuts down while playing a game

Hi  everybody,  I had the same problem in my work's notebook, and apparently we had solved it. We just erase the "HP QUICK LAUNCH" app and restart the computer. It has been working without problems for the last 3 days. 

Hope this help.
