Almost a year on from its release and the Dell XPS 15 9570 is still suffering from countless issues

This week may have brought some relief to XPS 15 9570 owners with Dell fixing its seemingly never-ending DPC-related latency issues. However, there are still several issues outstanding that Dell either is still yet to fix or refuses to do so.

These are the main issues that we have either noticed ourselves when testing various BIOS updates on multiple XPS 15 9570 machines, or problems that others have reported online:

Some machines are suffering from NVIDIA GPU related fan issues. These appeared post the release of BIOS 1.7, which fixed the NVIDIA GPU issues that had been affecting some machines since BIOS 1.3.1. Dell has informed us that this is apparently normal behaviour, although it did not exist pre BIOS 1.7.

Moreover, Dell removed S3 sleep as of BIOS 1.3.0, as we have previously reported. Frank Azor has stated that the company is "working on a solution". He has since gone silent on the matter though.

Thirdly, there have been multiple reports of BIOS 1.6 introducing a bug on 4K models that oversaturates colours. We understand that this is still an ongoing issue.

Finally, Dell reduced the rate at which the NVIDIA GPU in the XPS 15 9570 thermal throttles from 78 °C to 74 °C, as pointed out on multiple forums online. The original temperature limit is far short of the maximum operating temperature of the GeForce GTX 1050 or 1050 Ti, and effectively means that either GPU cannot reach its full performance.

The next XPS 15 is now on the horizon, and we hope that Dell is not going to abandon its current popular 15.6-inch laptop. However, it still has numerous issues that have either been introduced post its launch. Please let us know in the comments if you have experienced any other issues or have found workarounds to the ones that we have listed above.
