XPS 15-9570, BIOS 1.3.0, sleep mode gone?

Received 9570 5-Apr … set up system then closed lid. Fans running never went to sleep. So searched for Dell 9570 Sleep and here I am.

Modern Sleep was never intended for a laptop, in particular a high performance laptop.

Received CRA 8-Apr and returning to Dell. Pretty limited choices out there so will have to do serious research as this lack of S3 support should be front and center to customers.

Somewhere there is a Product Manager that needs to be immediately terminated for such a ridiculous decision to implement Modern Standby on the XPS series.

Yeh, this laptop is truly half baked. Unfortunately I didn't have time to follow up on any of this but I will have more time now and am going to be chasing support for solutions to all these issues, not that I am hopeful they will deliver.

How many laptops get articles talking about resolving the issues .... you missed the audio issues :p

Hi macastroham,

Thanks for posting.  Apologies that your system is not performing as expected.

Microsoft has changed the S3 sleep mode we're used to with the Modern Standby, which has different features and works differently.  Here is information from Microsoft about Modern Standby.

Dear Robert, 

> Microsoft has changed the S3 sleep mode we're used to with the Modern Standby, which has different features and works differently.  Here is information from Microsoft about Modern Standby.

We are aware that with MS/CS Dell is just following the development at Microsoft and Intel. But here we need you to to get the message back to them, that MS/CS isn't as good as S3 in certain very important aspects, like battery drain, bag-safety. Debug tools like SleepStudy are over the top for an average user, and even if an "offender" is found there is often little user can do except for sending emails to support, often with zero effect (have you noticed the page count of this thread???). We want them to go back to the drawing board, at least allow user to force unconditional DRIPS state. And we are asking you to re-enable S3 until this is fixed, like Lenovo did. 

Just wanted to add that I too have experienced a hot laptop which I assumed had gone to sleep, but had actually not thanks to the inferior so-called, "Modern sleep." My laptop almost started a fire via papers on my desk! It's so hard to understand why Dell would take the Samsung "just ignore the exploding phones" strategy instead of just fixing it (which would be simple). If I were a shareholder, I'd be worried. This could hit the bottom line once fires start breaking out.

Ya, not holding my breath either, and still running Bios 1.2 so I don't lose S3.  Would be nice to get and updated bios AND proper sleep.

Though, tbh, it looks like the newer bioses are plagued with other issues too - so maybe I should just stay on 1.2...

Also, found a semi-solution to modern standby sucking.  I just put my XPS in to airplane mode before sleeping.  It's a pain in the **bleep**, but at least the **bleep** stays asleep.

Did anyone try the latest BIOS ?

Dont see any mention of sleep mode :(

No don't worry... It's jusr another worthless update, which could cause more problems at the end. 

That's nothing more than ridiculous Dell... But what am I talking. They don't care anyway about what we are saying here

Guys a new BIOS update is out!!!

Reduces Deferred Procedure Call (DPC)! Which might is the solution at least for the sound issues.

Update.  Gave up on trying to use S0.  Even with airplane mode and mute it was waking up in my bag, or when I was trying to sleep the fan would come on every 5 seconds.

So.

I cleaned off everything except data + work apps. 

Used disk2vhd to take an image of the disk and store on my NAS.

Used bios to force S3 (Yes, I'm still on bios 1.2 and refuse to upgrade till Dell brings S3 back)

Reinstalled Windows from scratch.  From ISO from MS.

Also took the opportunity to /also/ install a Linux partition so I can test if Linux is ready for the desktop yet.

So far, so good!  Laptop SLEEPS.  Like, actually SLEEPS.  When I close the lid, it goes to SLEEP and DOESN'T WAKE UP EVERY 5 SECONDS!  

Previously, when I'd just forced S3 without a reinstall I'd get strange issues with the display flicking to black for a second every min or two after waking from sleep.  That has not been happening after the reinstall.

Only issue so far is that the sound drivers are wonky.  Flat out doesn't work right.  Tried MS supplied realtek drivers, and they worked for a few mins and then stopped.  Tried the Dell drivers - same deal.

Have a USB headset, though, and that's been working fine in the short term.

Once machine was reasonably happy I copied the VHDX back over, extracted req'd files, etc.  Easy-peasy!

Also heard a rumor that Dell is actively working on reenabling S3 in the newer bioses.  So maybe 1.11 will have S3 back!  Fingers crossed - I'd love to upgrade past 1.2.

thanks @ZDC  that is actually a good idea .... clean install .... i recall reading something about windows setting S3 at the time of install..... just didnt have the time to try that but i might also hold on for newer BIOS with S3 enabled before doing that, I dont really want to run on an older BIOS, could be some security issues going forward.

Come on Dell .... 1.11 enable S3 again !!!!! PLEASE!!!!!!

Yes, but other manufacturers have realized the issue and extended support for S3, not to mention the fact that other operating systems still use S3. Just Google Lenovo S3, forums are full of their customers also complaining with the result being a new BIOS with S3 support coming back.

I understand everyone's anger at Dell for taking away something that is very useful. However, the real issue is that Microsoft has changed Windows 10 and they are the ones responsible for the loss of S3.
