Windows Shutting down

[timbeh]

Hello, Fellows!
I am new member to help the project. It is very important and I have asked my friends to help also to share their computers.

But, I installed Folding software , and after 15 minutes, more or less, my laptop shuts down. I have no idea if is overheating or something else.
My power settings are to NEVER shutdown screen or laptop, and i always use like that and never shut down. I saw this happening after run the client at my machine.
In this way, i cam not able to help 100%, only after start login session again.. run... shutdown.. start again... and so on...
Kindly ask your help on that.
I am using a DELL laptop E7250 with windows 10.
Thanks!

It is likely overheating. "Ultraportable" laptops are not usually built for continuous full-load processing.

You can check your temps with HWMonitor from CPUid. If they are getting high (>90°C, since TjMax is 105°C), you can try to restrict either the CPU clock (in BIOS or Power settings) or the number of cores F@H uses (in F@HClient). However, it is possible the machine will not Fold successfully...

Have you got something like Intel Power Gadget, CoreTemp or HWMonitor installed, where you can observe the CPU and GPU temperatures?
F@H loads the processor with AVX 256 instructions, which causes a lot of heat. the average bench or stress test program wouldn't put such a heavy load on it in terms of heat and power consumption, even though the CPU load might show as 100%.
Therefore, maybe install HWMonitor or one of the other programs and check what temperature your CPU (and GPU if you fold on that, too) get to. Play around with the settings for your CPU slot in FAH Control and maybe reduce the number of threads (called cores in FAH) and see whether it works better.
A lot of laptops aren't designed to take a full AVX work load at 100% over several hours (or days). The cooling system just won't cope unless you got a good gaming or workstation laptop with beefy cooling system.

I think that you overheat the CPU,
I tried F@H at my gamer laptop first, thinking it's strong enough. Although it is good hardware and cooling is not bad either, CPU and GPU temperatures wentr crazy high, near 100C even if I was using a cooling pad with fans underneath and the laptop was dusted off with compressed air.

Cooling of laptops is not designed to run the CPU / GPU at 100% load for hours without pause. So, a high end laptop is designed to handle moderate load (gaming) or high loads that last for some minutes (like compressing a file or editing picture/video) and after that it can cool down.

Workaround is to reduce the number of cores that F@H uses, to something like half of the cores, than it shoud stay at safe temperature.

Just the simple lifting of the computer off the surface below it can help. I have my laptop sitting on four caps from water bottles, although you can purchase a tray with a fan in it that also lifts it up slightly. A lot of the heat is dissipated out the back.

Before you do, though, do try to blow the dust out of the grills where the fan blows the heat out the side. (The fan is working, right?)

It depends on the model of laptop. I had a Sager NP9150 laptop (i7-3840QM with GTX 670MX) and was able to fold on CPU (7 CPUs) and GPU 24/7 for years. I ensured there was enough clearance between the table and the laptop using 2 bottle caps. I didn't need to use any cooling pads and temperatures were in the high 70s. I would regularly clean the ventilation and after ~3 years, pulled everything apart, re-applied thermal grease and then it was good for another 2 years before I donated it.

I'm wondering whether high temperatures approaching 100 degrees C aren't acceptable for Intel mobile CPUs of the recent 5 years or so.
I have observed on my Macbook Air that it allows the CPU go to about 97 C quite happily, doesn't matter whether I run 2 or all four threads. At 2 threads and about 77% load on the CPU the fan is just running a lot slower than when 4 threads are busy at 100% load. Temperatures stay the same, fluctuating between 96 - 99 degrees.
The Lenovo laptop, which is a brick compared to the Macbook Air, behaves similar, it just seems to aim for < 80 C.
Somebody else mentioned in a different thread here, that his much more recent Dell laptop with a 6 core (or more?) Intel CPU runs at nearly 100 C, doesn't matter whether he allows all logical threads / cores or only 2 or 4 threads. I would guess that high temps seem acceptable and the priority is low noise emission.
If the cooling system is able to keep temps at just under 100 C with partial as well as full AVX load, I'd say it's adequate and the focus is more on noise levels than low temperatures.

It depends a bit on the CPU and the kit it is in - but yes current CPUs have a much higher TJmax than older generations … Whilst FAH runs CPUs hard, modern kit should manage heat appropriately (home/diy/overclocked is different) but the way it tends to do this (in simple terms) is by spinning fans up to max to get max cooling and then throttling back the CPU speed until a balance is reached.

Now the problem with this is that people quite rightly don't like the noise (and also tend to get concerned by their kit feeling warm/hot - and there are ways to address this by altering the default behaviour of the system and by adjusting the way fah uses the kit (less cores, etc) … Curiously the fact that FAH runs the CPUs hard but at a consistent temperature will mean that from the CPU perspective there is less thermal stress than in a scenario (possibly gaming) where the temperatures are ramping up and down continuously.

My 4core Xeon Dell Precision 5510 laptop runs 8 threads and maintains a nice stable 93C with little/no throttling - and actually is quiet too as it was designed to be worked hard - So I am very lucky.

Imho it is worth a bit of time researching ones kit to find out what the max temps for the CPU are and understanding how the kit cools … I used to have an Alienware MX11r2 (iirc) which was a tiny laptop with a big at that time graphics card … It only had one heat pipe so the CPU preheated the cooling for the GPU (it could have been the other way round) - I do remember pushing temps well past 100C and then discretion took over from valour and I stopped the stress tests - it may have been the only way they could cram it all in but it was pretty useless at getting rid of heat.

Additionally there is a difference between each core temp and cpu temp. The overall CPU should maybe stay below 80°C while individual core can reach 95°C before throtteling.

You can also limit CPU power usage if you like e.g. in Windows power options set CPU max speed to 99% will disable CPU boost clock and lower temp.

Isn't it funny, we spend hundreds of euros on PC hardware, and then this...
PS: Mine is sitting on two flat LED flashlights that I got for free from an ad campaign.

Bottle caps, simple and cheap, and easily replaced when my cat takes one for a play toy.
