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?
Dell has decided to support the "Modern Standby" from our partner Microsoft. If you decide you wish to use S3 instead of Modern Standby, you can attempt to install an older BIOS, but Dell cannot assist in this.
There is an easy fix for this problem! Works with the latest bios and all older bios and it forces S3 Sleep. Been using it for a while and it works. It disables the Dell modern standby (wich causes the problem) and sets the regular sleep function as default. (the sleep we all know and love, no fan spin, no random wakes)
Press start -> type: regedit -> press enter. Then navigate to:
When you press the second to last folder (power) there is a file on the right side called CsEnable. Right click it, press modify and set the value to 0.
Tada! No more modern standby and regular sleep function has been restored! After that check the bios power settings and make sure al the “wake on ….” Functions are turned off.
Disclaimer: Be carful when working in bios and registry edit. Also, this fix is working golden for me but be carefull, after an update by dell it might revert back to old sleep someday and overheat again.
The problem doesn’t occur with me so I cant reproduce it. My best guess would be to do the following:
it might be happening if the network adapter is allowed to be disabled to save power on hibernation and/or sleep. To uncheck the setting, follow the steps.
Open Device Manager
Expand Network Adapters
Right click on the Network adapter installed on your computer
Go to Properties
On the Power Management tab uncheck all the boxes and apply the settings
Restart the computer and check if the network card works fine.
The latest bios version removed some redundant setup options. That is one that they must have removed. In order to set the systems sleep options in Windows 10 follow the information below to set them to meet your criteria.
Start-Settings-System-Power & Sleep. From here you can change the settings for each to your desired setting. After you have done each one of these click on Additional Power Settings at the bottom. Click om each settings on the left hand column and change the settings on the right. Do this for each one. These should take care of your sleep settings for the computer.
Thanks for posting. Apologies if your system is not performing as expected.
As explained earlier, the BIOS control over sleep is no longer available in this model. However, you can adjust the sleep settings in Windows 10:
Start-Settings-System-Power & Sleep. From here you can change the settings for each to your desired setting. After you have done each one of these click on Additional Power Settings at the bottom. Click om each settings on the left hand column and change the settings on the right. Do this for each one. These should take care of your sleep settings for the computer.
My information was from KB Article SLN314237, The article states: As XPS 9570/Precision 5530 is modern standby supported platform, S3 mode is not officially supported per platform design. Refer to the Microsoft support site for the behavior difference between S3 and Modern standby. Please guide the customer to apply the BIOS 1.5.0 from Dell support site. For those systems with Force Sleep enabled and then applied the BIOS 1.5.0, the system would be capable to run S3.
Since you've said this isn't working, I'll let the engineers know. Thanks.

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.
I'm not sure that will solve my problem.. The sleep mode in BIOS can force the computer to go into S3 sleep mode directly, window's power setting does not allow me to change the sleep mode. My problem with this laptop is that I can not make this laptop sleep (into S1) using the power button - since the power button is also a finger print scanner, if I use the power button to sleep the laptop, the finger printer scanner will wake up the laptop immediately.. It is also an issue when I use my mouse to sleep the laptop, if my touch move the mouse a tiny bit after I click on the 'sleep' button in windows, it will wake it up. Also, in S1 mode, my battery drains much faster and the fan sometimes continue to spin even in sleep mode.
This mode is very useful to solve XPS's sleep problem:
