XPS 15-9570, BIOS 1.3.0, sleep mode gone?
I just bought my XPS 15-9570 with BIOS 1.2.2 installed, and I updated it to BIOS 1.3.0. I realized that the "sleep mode" option is now gone. I need to set this to "Force S3" sleep to prevent the laptop from waking up randomly, or don't go to sleep properly. So can I do that in the new BIOS?

The BIOS option to force S3 is what lets us install Windows /without/ it defulting to S0.
Otherwise at install it default to S0.
Then requires a reinstall to switch to S3.
But it then defaults to S0 requiring a reinstall to switch to S3.
But it then defaults to S0 requiring a reinstall to switch to S3.
But it then defaults to S0 requiring a reinstall to switch to S3.
But it then defaults to S0 requiring a reinstall to switch to S3.
Until Dell gives us the force S3 option back.

This is not a fix, but it is my favorite alternative. These laptops will hibernate, even though the option is not shown in the power menu.
Create a batch file called hibernate.bat on the desktop with the following command:
shutdown /h
It will save the state to disk, and shutdown. then it will restore when powered back on - which all happens pretty fast thanks to the SSD.

Been having the same issue and I somehow sorted it out (still testing though). My laptop wouldn't go to sleep and what's worse, S0 Low Power seemed to make Linux VMs in VMWare player freeze when I the host was going into that state. So last evening I set off on trying to sort it out.
* I've updated my BIOS to latest (1.18).
At this point when checking `powercfg -a` it would say S3 is not available because of S0 Low Power
* Enabled S1-S3 in GPO: https://superuser.com/questions/1179987/activate-sleep-states-after-win10-install
* And then disabled Modern standby in registry https://code.luasoftware.com/tutorials/windows/win10-problematic-modern-standby/
At this point when checking `powercfg -a` it would say S3 is supported and S0 Low Power not available.
I can't remember what version of BIOS I was running when I'd last installed the OS. There's posts saying that some settings will only work if when installing the OS S3 was available. So perhaps I was on a version that still supported S3 when I've installed the OS ...
Hope it helps others as well ...

Didn't show up for me when I first tried, but somehow it worked after the third time. Seems like it needed a proper restart in between. My laptop is now sleeping... thank you!!

Only problem I'm running into now is that that my network adapter isn't recognized after coming out of sleep. Somebody has a fix for this?

Hi,
Hi polarbeardk,
It could be that the power multimedia settings are messing with the sleep settings. I can reproduce your problem with a second screenattached by making a change in my power settings. So maybe that is set the way I set it to reproduce the problem.
Go to: Control Panel -> All Control Panel Items -> Power Options -> Edit Plan Settings.
Click on advanced power settings.
In advanced settings go to Multimedia settings -> When sharing media -> prevent idling to sleep
Not sure if this is the fix so remember how it was set before you change it.

I just logged in to say THANK YOU! I'm so happy to have normal sleep back. Last night I had charged my laptop to 100%. I got to work this morning about 10 hours later, and my laptop had 64% battery left! Found this solution, and battery life is back to what it should be. Thanks!
