Dell is reportedly working to bring back S3 sleep to the XPS 15 9570

[Redaktion]

A glimmer of hope, perhaps? It now seems that Dell is backtracking on its refusal to reintroduce S3 sleep mode, which it removed from the XPS 15 9570 with a BIOS update nearly a year ago. Its removal caused an outcry from some owners who complained of excessively high battery drain caused by the mode's removal.

Don't suppose this will come to the 9380 as well?

um, when is the dang 9580 going to be released. It is already mid April and NOTHING????

Seems to be an issue with some other Dell models too. I have an m15 that shows similar sleep behavior to the 9570, spinning up fans while supposedly asleep for example (lid closed, light pulsing), but I don't know how to check to see if it has S3 sleep.

My XPS 15 9570 was constantly waking up in my backpack without me realizing it, and it would be burning hot to the touch. This happened multiple times before I finally disabled sleep and forced it to hibernate every time I close it when unplugged. This is so annoying and inconvenient but I really dont see any other options at this point. Also when I'm rendering videos I literally have to put my laptop in the refrigerator for the GPU to reach top clocking speeds. Also sometimes the sound card decides to act up and start making every sound crackle. I fix this by switching it into Windows Spatial Sound and then switching it back and it works fine but it's still one more stupid thing that's wrong with this laptop. I simultaneously love and hate this thing with a burning passion. It's so beautiful and powerful but always seems like there's annoying issues popping up.

i have exactly the same problems with my 9570.

More likely their lawyers or such are. Problem is, Microsoft demands S3 removed from computers to be certified for MS/CS (CPU sleep time is obviously to valuable to them to let users make CPUs sleep without draining the battery). I guess Dell is merely happy to comply, because they were never able to debug S3 properly, and they certainly hate the idea of having to support two sleep options.

I recently purchased a laptop and due to the S3 sleep state i am experiencing very bad impression about Dell Xps 15 9570. I can't hold my work and hibernating is sometime works but most of the cases it shutdown my laptop. This is critical issue and need to be solved as soon as possible. if i know this issue happens in Dell xps 15 9570 then i will go for the another laptop. This is really a critical issue.
