I had the same issue when I would play a game or exert my laptop too much. This was until I opened up my laptop and cleaned out all the dust and fluff that was affecting my fans movement. I don't know if it relates to everyone's issues, but it certainly worked for me.
I made up a case in my support area.
I got the advice to deinstall my "Intel thermal framework (hat A09 installed)" and to install "Intel thermal framework A04".
After that I made a burn in test with Furmark wich crashed my device before... and it seems to work.
CPU and GPU up to 100% (nearly) and seems to be stable.
Will test it with a game later on.
Seems to be fixed by downgrading to Intel Thermal Framework A04
Ran some burn in tests and a game with high CPU/GPU usage and it works....
I've been having this exact problem - random laptop shutdowns - and I think I have found the solution for my xps 15 9560. I thought it was related to the new battery I installed, but it is not. I found out with my laptop that it is directly related to the Intel Graphics 530 driver.
1. 2 weeks ago, my laptop just kept randomly shutting down - like the power was just cut completely.
2. I updated the bios, but didn't seem to do anything. Still shutting down.
3. I upgraded the "intel thermal management framework driver" - a solution I found on Dell support threads, but didn't seem to do anything. Still randomly shutting down.
4. Finally, I installed an old 2016 Intel Graphics 530 driver instead of the currently installed 2017 driver.
Suddenly, no shutdowns at all. For a week straight now, I have not had one shutdown and my xps 15 has been running like a dream - long battery life!
Here is why I know the graphics driver is the culprit. This morning, I went to Windows Update and saw on the list that it was going to update my Intel Graphics 530 driver. I kept Windows Update open and watched it download and then install - and I restarted to let it finish all the updates it was doing.
As soon as I restarted, my random shutdowns began again! Every 2 minutes or so, my xps started to randomly shut down. After the 3rd shutdown, I quickly restarted and went directly to 'device manager' as fast as I could to roll back the Intel Graphics 530 driver.
As soon as I rolled the driver back to the 2016 driver, my xps is once again, not shutting down and working like a dream.
I hope this might help anyone else having problems with this issue. Now I just have to see if I can get Windows update to stop automatically updating that driver!
Just repeat for new peoples who still have problems with it!
I found solution for me, just install the oldest version of Intel Dynamic Platform and Thermal Framework from here, and all problems has gone.
