If I did a fresh install of windows 10 and got rid of the Dell bloatware, does the Dell dynamic power policy still work?

"The aim of the article is to show the principle and theory behind Dell's power policy and not a critique to its current application deficiencies. "

I'm sorry but it does indeed read like a Dell ad. It is well known that in real life, after a few minutes of high combined CPU+GPU load, Intel DPTF kicks in abruptly and heavily reduces the clocks, often lower than required, rather than smoothly reaching an operating point at the edge of thermal limits.

The borderline thermal design is also very sensitive to production faults. Out of the factory, a considerable percentage of XPS 15 obviously experience direct thermal throttling of the CPU and/or GPU under high load. This can be fixed relatively easily by repasting, however it is rather unfortunate to see laptops in this price range being shipped to users failing to perform the essential quality control steps.

Finally, the modding community at Notebookreview forum has shown that quite reasonable performance under full combined CPU+GPU load is possible without Intel DPTF kicking in within the same physical dimensions after certain modifications of the cooling system which allow heat to be more efficiently removed from the VRM area.

Thanks for exposing the truth

What is this, some paid advert??

You should report then how with all this fantastic temperature management that the Dell xps 15 (9550) has issues with temperature causing swollen batteries, pushing  the track pad so far out of the chassis that it becomes useless.

And it's a problem Dell recognises because they've been fixing laptops outside of warranty!

No. This is not a paid advert. We mention clearly up front if the article is sponsored. I totally understand that Dell had had some reps with respect to throttling in XPS laptops as well as issues with temperature. The aim of the article is to show the principle and theory behind Dell's power policy and not a critique to its current application deficiencies. May be that can be a subject of a future analysis. Thanks for reading, though.

Sorry, I was too harsh with what I wrote.

I appreciate you writing up the article on the swollen batteries as I really do want there to be more coverage about issues affecting large numbers of people.

Thanks for the hard work!

Yes. Its good that Dell has finally started to acknowledge issues with their batteries. OEMs should never take such things lightly in the larger interest of user safety and customer trust.

you do realize that this is something dell just implemented, right?

I don't give a s*** how they manage the thermal and power policies, fix the coil whine hell first!

Using a combination of hardware and software, Dell designs its XPS lineup of notebooks to dynamically adjust power inputs to the various components to ensure that the system operates within specified temperature limits. We explain how Dell implements its Dynamic Power Policy to maximize performance within design constraints.
