So basically, when you use S3 mode, you will lose up to 15% of your battery life unless you reboot after every time it sleeps!!! Ouch! I verified this myself - the C-States get hosed after S3 sleep EVERY SINGLE TIME. The reason is that it is buggy and they were too lazy or incapable of fixing the bugs. I think Dell did have a reason for removing S3.

If all worked fine, and booting into Windows 10 again via reFind, doing a "powercfg /a" should tell you, that S3 is now back enabled. (optional) Enable "secure boot" in your bios

Open a cmd.exe command prompt as administratorĮxecute: mountvol S: /S (if you already use a drive S: use a different letter not in use)Įxecute: cd C:\temp (where you have the zip extracted so it contains the "refind" folder)Įxecute: bcdedit /set "" description "Windows boot manager" (optional) you can look into the C:\temp\refind\nf if you like and edit it to your wishes Be aware though, that using S3 on the 9570 at least causes a bug causing a permanent 1W drain ( ) which Dell never looked into fixing.ĭisable "secure boot" in your bios (has to stay disabled as long as you use refind)ĭecompress refind_fix.zip to a folder for example C:\temp I tested this on my own Dell with bios 1.16.2 and Windows 10 2004. I have not tested this with bitlocker and if you use it, you mostly have to disable it before changing the boot loader!! It is straightforward and should work normally, if you do it correctly though. Be aware, if you use Windows Bitlocker, you may have to disable/suspend the Bitlocker service temporarily before you mount the EFI partition.

The patch is not permanent, and is being applied for every boot, when rEFInd loads, so it is easy to revert back to modern standy, by just reverting back to the normal Windows boot manager or by removing the AcpiPatcher.efi in the EFI\refind\drivers_圆4 directory.ĭoing the following is at your own risk. Youd mostly have to do a clean Windows 10 installation after setting up rEFInd.Ĭredits for the patched "rEFInd driver" (the AcpiPatcher.efi can be used from any efi shell), which disables modern standby at boot time via editing the ACPI table go to:

Especially after Windows 10 2004, where MS removed the CsEnabled option from registry, and there is no way anymore, to get S3 sleep back on devices, which force a modern standby sleep, and have no manual option in bios, to force S3 sleep.ĭont do this on new AMD Ryzen 4000 laptops! There were reports of this causing a bluescreen caused by one of the AMD drivers. The following procedure should work (no guarantee, just tested on Dell XPS 15 9570) on all Intel 64bit laptops which support both S3 and modern standby ( not tablets, which dont support S3 in the first place), and for people, who have the desire to get S3 sleep back on their laptop under Windows 10. If you already have a dual boot environment, you have to replace your boot manager with reFind being used in this tutorial. Also just for a normal Windows environment with no other boot manager being used other than the normal Windows boot manager.

Warning: if your laptop is newer than 2019, there is a high chance, your OEM removed any S3 code from the bios, and your laptop will crash entering S3 and you have to force hold power key to restart and then delete the registry entry again to revert back to modern standby. Reg delete "HKLM\System\CurrentControlSet\Control\Power" /v PlatformAoAcOverride You can just run regedit as admin and delete PlatformAoAcOverride under HKLM\System\CurrentControlSet\Control\Power again to revert back. Reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0 Removing the entry again to get back modern standby.
You might be able to disable modern standby with this registry flag, so no refind needed, so setting PlatformAoAcOverride to 0 under HKLM\System\CurrentControlSet\Control\Power. Or has just bad drain in general, compared to S3. You CANT revert back to S3 now anymore, and are stuck with bad modern standby, which is a ticking time bomb, can melt your laptop to death or drain your battery in 1-2 hours randomly. Up from Wind(2020 May update), MS also removed the CsEnabled option from registry.
That was already a disgusting and incompetent move, however, the worst was yet to come:
I was just tired of Dell and also Microsoft, both forcing you into Modern Standby, which never worked, doesnt work, and will not ever work reliable on Windows, compared to 100% working and reliable S3 (suspend to RAM) sleep.ĭell removed, for NO REASON, the bios option on most of their laptops, to force S3 sleep (long gone on 9570 since bios 1.3.0).
