Important update

A much simpler method was described by @nullsvm in this comment, which involves modifying a UEFI variable directly using the RU.EFI BIOS editor. It worked for me on X13 2021 (bios versions 412, 413, 414) and for some others (here and here) on X13 2022, but some 2022 owners report it doesn't work for them (see comments).

I'm keeping the original text here even though I'm not using the Clover method anymore; IMHO you should try the RU.EFI route before using Clover.

Purpose

This gist documents a workaround I'm using on my ASUS GV301QE (X13 flow 2021) to replace S0 sleep (AKA modern standby or S0ix) by S3 sleep (AKA deep sleep or suspend-to-RAM).

This involves modifying one of the ACPI tables, called the DSDT. The modification is not permanent - nothing is written to the firmware itself - but rather through a bootloader that loads the modified DSDT before Windows starts.

I chose to go through Clover EFI bootloader; the same can be achieved on Linux via an initrd (see, e.g., here). Clover's main aim is to enable running MacOS on non-Apple systems, but we only care about its ability to load custom ACPI tables before booting Windows.

Software needed

• Clover - CLOVERX64.efi.zip is enough, I used r5149.
• IASL compiler - we only need iasl.exe

I assume you downloaded these and extracted the files CLOVERX64.efi and iasl.exe to C:\Users\YourUserName\Downloads. Replace YourUserName here and in the instructions below with your actual user name.

Overview of steps

1. Disable S0 sleep via Windows registry.¹
2. Install Clover to the ESP.
3. Disable Secure boot in UEFI setup.
4. Set Clover as the default boot option in UEFI setup.
5. Dump current DSDT using Clover.²
6. Patch DSDT to enable S3 sleep using iasl.
7. Place patched DSDT in Clover's directory within the ESP.
8. Configure Clover to automatically load Windows upon reboot.
9. Optional: install a Clover theme.

With this order of steps, only two reboots are necessary :)

Detailed explanation of steps

Step 1: disable S0

Run Command Prompt as Admin.

To disable S0 sleep, type in the Admin Command Prompt:

reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0

Keep Command Prompt open for the next step.

Step 2: install Clover to ESP

Mount ESP:

mountvol R: /s

Create directory structure for Clover:

mkdir R:\EFI\CLOVER\ACPI\Windows
mkdir R:\EFI\CLOVER\ACPI\origin

Install Clover:

copy C:\Users\YourUserName\Downloads\CLOVERX64.efi R:\EFI\CLOVER

Clover works fine even without a configuration file, but we'll install a basic one in Step 8.

Edit: ACPI_BIOS_ERROR BSODs are reported with an empty configuration file, let's do it now.

Create a basic configuration file for Clover:

notepad R:\EFI\CLOVER\config.plist

Copy and paste the following in it:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Boot</key>
	<dict>
		<key>Timeout</key>
		<integer>-1</integer>
		<key>Fast</key>
		<false/>		
	</dict>
	<key>GUI</key>
	<dict>
		<key>Scan</key>
		<dict>
			<key>Entries</key>
			<true/>
			<key>Legacy</key>
			<false/>
		</dict>
	</dict>
</dict>
</plist>

Step 3: disable Secure boot

Restart the computer, and press Esc to show Boot Menu. Enter UEFI Setup (last option).

Press F7 to switch to Advanced Mode. From the Security tab, disable Secure Boot if it is enabled:

Keep UEFI Setup open for the next step.

Step 4: set Clover as default

From the Boot tab, add a boot option for Clover:

Select Clover as Boot option #1:

Save and exit UEFI Setup, Clover should boot.

Step 5: dump ACPI

Press F4 to dump ACPI tables. There is no visual feedback, but Clover saves them to EFI\CLOVER\ACPI\origin.

Boot Windows ("Microsoft EFI Boot", usually leftmost option).

Step 6: patch DSDT

Run Command Prompt as Admin.

To verify that S0 is disabled, type:

powercfg /a

The important line is

Standby (S0 Low Power Idle)
   The system firmware does not support this standby state.

Mount ESP and copy original DSDT to working directory:

cd \Users\YourUserName\Downloads
mountvol R: /s
copy R:\EFI\CLOVER\ACPI\origin\DSDT.aml .

Decompile DSDT using IASL and edit it using notepad:

iasl DSDT.aml
notepad DSDT.dsl

Two changes are required: bump the version and enable S3.

1. Increase the last number in DefinitionBlock (e.g. from 0x01072009 to 0x0107200A):

   

2. Search for XS3 and change it to _S3:

   

Save DSDT.dsl and recompile:

iasl DSDT.dsl

There should be warnings, but not errors.

Keep Command Prompt open for the next step.

Step 7: install new DSDT

Copy the modified DSDT to the ESP:

copy DSDT.aml R:\EFI\CLOVER\ACPI\WINDOWS\

Keep Command Prompt open for the next step.

Step 8: configure Clover

Edit Clover's configuration file:

notepad R:\EFI\CLOVER\config.plist

Either change the Timeout parameter from -1 to 2 to make Clover boot Windows in 2 seconds, or change the Fast parameter from false to true if you don't want to even see Clover during boot. Save the file and reboot.

Step 9: Clover themes

Place your favorite Clover theme in \EFI\CLOVER\themes and reference it in config.plist:

See here for a list of themes.

Troubleshooting

Battery missing

If S3 sleep works, but the battery is not detected, then you might have dumped the ACPI tables incorrectly. Specifically, using acpidump.exe from ACPICA tools is known to create this problem. Dump from Clover, using F4, and patch it (Steps 5-6-7).

BSOD upon wakeup

If you get intermittent blue screens when waking up from S3 sleep, check whether the driver involved is AMDACPBUS.SYS (AMD Audio CoProcessor). Version 6.0.0.29 was reported doing this; version 6.0.0.50 seems OK.

Edit: all versions of AMDACPBUS.SYS seem to handle S3 sleep badly. One particular annoying behaviour is that upgrading the AMD graphics driver causes a BSOD ("Driver unloaded before cancelling pending operations"). I keep this device disabled.

To fix, disable the AMD Audio CoProcessor device in Device Manager. Not idea what it actually does.

To fix, update the AMD graphics driver (5800HS/5900HS or 6800HS/6900HS). Maybe it also helps to install the latest AMD chipset drivers.

BSOD after BIOS update

ACPI tables are stored in the BIOS, so after upgrading most likely you get partial behaviour or BSOD upon boot.

To fix, re-dump and re-patch DSDT (Steps 5-6-7). I actually had to do it twice afte upgrading to BIOS version 413 (after upgrade, I got a BSOD upon boot; after first iteration, S3 was working but battery wasn't detected; after second iteration, everything is OK).

Flashing lights while sleeping

During S3 sleep, the power on led on the left side double-blinks. If you're annoyed by the keyboard backlight double-blinking, this can be disabled in Armoury Crate->System->Lighting->Settings:

Reverting changes

• To re-enable S0 sleep, open Command Prompt as Admin and type:

reg delete HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride

• To disable Clover temporarily, choose Windows Boot Manager from the Boot menu.
• To disable Clover until further notice, enter UEFI Setup and set Windows Boot Manager as boot option #1.
• To uninstall Clover, open Command Prompt as Admin and type:

mountvol R: /s
del /s R:\EFI\CLOVER\

Future work

• Design a proper ROG theme for Clover :)
• Understand why the ROG red logo isn't showing when Windows boots. I have it working in a slightly different Clover installation, so it must be something about the drivers or the OEM config. Update: the OEM logo is referenced by an ACPI table called BGRT, which contains a physical memory address. Maybe this memory area is overwritten by Clover? anyway, it's possible to revert to the default Windows boot logo using DropTables in Clover's config.plist.
• Collect some more DSDTs; perhaps it's possible to provide the correct ones for each model in the ACPI\OEM directory and skip Steps 5-6-7.
• Understand whether Clover's mechanism for DSDT patching can be used directly, which could replace Step 5 altogether. Update: no :( since Clover's PatchACPI_OtherOS() function only supports loading ACPI tables from .aml files and the DropTables command.

Footnotes

1. This is needed since S0 takes precedence over S3 when both are available. ↩

2. Dumping must be done with Clover, since using acpidump.exe will get you a partially valid DSDT. Ask me how I know :P ↩

Thanks for the guide.
I have an ASUS ROG Flow x16 with massive sleep problems... Explorer hanging after sleep, USB Devices dying after sleep etc.
Disabled s0 with this guide and using s3 now solved all problems.

It's also possible to enable S3 support without ACPI overrides by manually setting a UEFI variable (GV301QE, bios 413).

Using RU.EFI, change the following (modern standby):

To this (S3):

At least on Arch Linux (kernel 6.0.11), this results in S3 being the default sleep behavior without having to change boot flags or override ACPI tables. Unfortutanately, the amdgpu driver still occasionally crashes upon resume (just as it did when overriding the DSDT). Windows users may have better luck.

fwiw - I discovered the address of the setting by decompiling parts of the UEFI firmware using uefitool and uefiextract. Maybe I'll write up a more thorough guide, but I generally regret avoid using my Flow X13 due to the shit Linux experience (recent kernel updates resulted in amdgpu crashing even without modifying UEFI settings).

Bonus: the boot animation can be disabled by zeroing out all of AnimeLogoSetup (replaced with black screen, seems slightly faster).

It's also possible to enable S3 support without ACPI overrides by manually setting a UEFI variable (GV301QE, bios 413).

Thanks! but is this a temporary fix? are UEFI variables stored in flash? NVRAM? what happens when you update BIOS?

Bonus: the boot animation can be disabled by zeroing out all of AnimeLogoSetup (replaced with black screen, seems slightly faster).

That's another thing I don't get. Boot animation shows (on Windows loading screen) if I choose Clover (or reFIND) from the boot menu manually, but will not show when Clover/reFIND boots as the default option. Any idea?

Thanks! but is this a temporary fix?

It's permanent unless you reset UEFI settings or update the UEFI. I'm not sure if it gets reset when updating unrelated UEFI settings.

what happens when you update BIOS?

iirc - the address of the setting remained unchanged when I upgraded from 412 to 413. I only needed to manually change it in RU.EFI again.

I still think it's probably a better idea to change the setting with RU.EFI than modify the DSDT. I compared the DSDT before and after and there were quite a few more changes than what you recommend changing. Not sure if they make a difference, though I did notice that there were no more ACPI errors in dmesg afterwards.

I've added DSDT dumps for both before and after modifying the UEFI variable. https://github.com/nvllsvm/asus-flow-x13-linux/tree/main/dsdt

diff between untouched DSDT and the DSDT after modifying the UEFI setting:

I tried it on my GV301RE. It works so far. The only difference is that I had to change both #003009 and #00300B to 00 (they were both 01 originally). I am not sure if the change is legit.

I changed
#0030 00 0A 14 14 01 03 01 FF 04 01 00 01 00 00 28
to
#0030 00 0A 14 14 01 03 01 FF 04 00 00 00 00 00 28

I am curious if you can undo this change? I'm using Windows and when I make set those two values to 00, I have access to S3 sleep, but I'm getting issues with the "amdacpbus" driver, and can't resume from sleep without crashing. Problem is, changing them back to 01 results in Windows giving an "inaccessible boot device" error on boot. Can you (or anyone) confirm this?

Edit: Some updates: changing 0030000B back to 01 seems to have no effect (can boot windows, S3 is still enabled). Changing 09 is the issue. I can boot into safe mode after changing both to 01, at which point neither S3 nor S0 are available.

Boot issues persist after re-flashing the bios, so I suspect it's an OS problem.

My guess is that one of the bytes is related to the SATA mode. I had the same issue when I undid the change. I first got into the recovery cmd and ran the following command

bcdedit /set safeboot minimal

Then reboot, Windows will automatically boot to Safe Mode. In the admin cmd, I ran

bcdedit /deletevalue safeboot

And then Windows boots normally.

I keep that device disabled, see instructions above.

so this still dont work well for me on Rog Flow x13 2022. already had my laptop waking up in my case super hot. got blue screen even after disabling the audio driver above

i still have to use Hibernate mode which my laptop have a unique weird issue that i need to turn it on and press like 10+ seconds to turn it off before it goes into weird cycle of on off a few times until it starts. dont have time to service it (i travel the world constantly) and i tried so many things to make it work better, including this solution.

i dont recall if i had this before but it is more profound now that the clock stopped updating automatically. every time i start the laptop the time is exactly when i got into hibernate last time after the Clover update.

if anyone has an idea..

I tired this method on Rog Flow x13 2022 (GV301RE - Ryzen 9 version) and it seems that Windows' BSOD after wake up shows when laptop hibernates after some time of being idle while sleeping. In fact it dehibernates, logs in and then BSOD occurs.
Turning off hibernate after some time solved problem for me (for now). Manual hibernation/dehibernation works just fine.

What is not working - clover setting to automatically boot windows, nor with timeout or Fast option.
I shall try ru.efi method if I make sure with clover method that waking up is stable.

@gambitaw - the symptoms you descirbed looks like S0 modern sleep or unprompted wake up. Disabling S0 is done via regedit. As for unprompted wake up - Windows sometimes wakes up from normal sleep mode f.ex. for updates etc. You should check system schedule tasks one by one and specifically prohibit waking up the computer for each of them. The clock issue is weird, time is measured by hardware clock, so the time goes on even when laptop is off, hibernated or sleeping.

@afr4283 did you disable AMD coprocessor driver?
Anyway I fully switched to the RU.EFI method, hitherto with no hick-ups whatsoever.

I did once at the beginning but I think disable wasn't persistent and it reenabled itself somehow (maybe after reboot) - I noticed it when my first BSOD after dehibernation occured.
Anyway, now it's enabled and no problems with wake up (driver version 6.0.0.50, date 17.08.2022).

I have :
Manufacturer: ASUSTeK COMPUTER INC.
Product Name: ROG Flow X13 GV301RE_GV301RE
Version: 1.0
BIOS Information
Vendor: American Megatrends International, LLC.
Version: GV301RE.323
Release Date: 08/30/2022

( snippets from dmidecode).
I don't run Windows, because really, who wants that (pun intended ;) ), but Fedora Linux (38 currently) and Ubuntu 22.04 LTS behave reasonably well when sleeping.
They use S0xi sleep , the crap that Microsoft and intel have been pushing, however it seems to work reasonably well in Linux for this laptop.
Sometimes there is no proper sleep but no crashes from sleep to wake usually.

I have a Dell Precision 5550 with a terrible BIOS bug, which seems like it has a half baken S3 implementation. Can anyone here perhaps explain how I can go about understanding the about 65k lines of DSL code of the DSDT tables?
I found a few S3 references but do not understand what is missing - the laptop either does not go to sleep and hangs at going there, or it does and hangs at wake. Any help is appreciated.
Also, complain to Asus and don't buy laptops without S3, as hard as it is getting one. Framework still has it and some Lenovo's too I think. I am personally done buying these toasters, the Tefal toaster does a much better job with bread.

This thread is a life saver since Reddit has not provided any solutions to the sleep issues. Screw Modern Standby ugh. I own the 2022 Asus X13 Flow GV301RE and I used the RU.EFI method. I've never done anything related to BIOS modding or editing before.

Basically the RU.EFI method worked and there are additional steps to take. I got a USB flashdrive and formatted it to FAT32. I did not use the Clover method.

Had to follow this guide. I went into the ASUS Bios and booted from the UEFI flash drive.
FSO: didn't work for me and I had to use a different drive, FS2: I think.

I pressed 'Alt =' to access the UEFI Variable. Then I eventually found "AMD_PBS_SETUP". From there, I followed WindPlume's comment.

Original
#0030 00 0A 14 14 01 03 01 FF 04 01 00 01 00 00 28
I changed it to
#0030 00 0A 14 14 01 03 01 FF 04 00 00 00 00 00 28

'Ctrl W' to save
'Alt Q' to quit.

What happened next was I had to disabled hibernation and fast start up by doing CMD as admin and then inputting "powecfg /h off". I had to ensure Hibernation and Fast Startup was already ticked off in "Control Panel\Hardware and Sound\Power Options\System Settings" prior to inputting the CMD command. Hibernation doesn't work right, everytime I hibernate, when my X13 starts back up, my apps are not saved and it's as if I just rebooted.

I disabled the AMD Audio Coprocessor in Device Manager.
I disabled Genesys 3.0 and changed it to Generic USB Mass Storage.

I verified everything with CMD run as admin
Powercfg /a

With every BIOS update ASUS releases via the 'MyASUS' app, this procedure has to be repeated. It's very fast. Sleep no longer causes issues now!

Glad you got S3 working :)

I got a USB flashdrive and formatted it to FAT32. I did not use the Clover method.

I don't use Clover anymore, the RU.efi method works great and allows you to keep secure boot active.
But it's easier to copy ru.efi to the EFI System Partition on the SSD and add a boot entry in the UEFI bios, so now I can run it from the boot menu (after temporarily disabling secure boot).

Works on GV301QH but after S3 state disabled Nvidia dGPU reenables (even if drivers were blacklisted in modprobe). I can track it with Watt metter (I use KDE widget).
So, before sleep the consumption is around 6-11 W, after S3 sleep - 27-36W.

It's also possible to enable S3 support without ACPI overrides by manually setting a UEFI variable (GV301QE, bios 413).

Using RU.EFI, change the following (modern standby):

To this (S3):

At least on Arch Linux (kernel 6.0.11), this results in S3 being the default sleep behavior without having to change boot flags or override ACPI tables. Unfortutanately, the amdgpu driver still occasionally crashes upon resume (just as it did when overriding the DSDT). Windows users may have better luck.

Tested on GV301RE (2023 ryzen edition, 327 bios version). But bios string a bit different, you will find out by hex position. Ubuntu going to deep sleep (S3) by suspend (S2). Windows not tested

@JayWing9 thanks for you detailed instructions the only thing which i missed was the hotkey alt+ =.
Also thanks to @raenye this make things much more simple.
Here are detailed instructions to copy ru.efi to your efi partion under windows. (so you do not need an usb-drive)
(Assuming ru.efi is on c:)

1. download this ru.efi version the latest did not work on my RV301RE.327 (production date 06/2022)
2. Open a Admin PowerShell (You can not access efi partion over the explorer)
3. mount the efi partion: mountvol b: /s
4. change dir to the efi partition: b:
5. copy ru.efi to the efi partion: cp 'C:\RU.efi' .
6. reboot into uefi and switch to the advanced settings
7. disable secure-boot
8. create a new boot-entry in the boot section
9. save and boot from ru.efi

I did not want to change the setting because i have a lot more pages available than you in other screenshots:

Does somebody has an idea?

@3deep5me please re-read https://gist.github.com/raenye/d6645d7039a6136ccfb055e0f8517698?permalink_comment_id=4579899#gistcomment-4579899

Hello, has anyone tested it on ROG Flow X13 2023 (GV302 model)? I modified the bios (for Fedora Workstation and Arch OS repectively) as per the instructions but nothing changed.

well i tried on mechrevo 14 pro 2023 and i was able to get s3 to show up in windows, but it never woke up from s3, then i changed back to 01, no boot, but need to go to safe mode and restart for normal boot, like in sata/ahci days.

Is there a way to make it wakeup from s3 after enabling s3? Same issue on asuses?

I have no BSOD on wake up,, however I waited about 2 minutes max, in event log there is only that the pc shut down unexpectedly (because i turned it off when it did not really wake up)

very woke this modern sleep

how can i verify my issue is also AMDACPBUS.SYS if i do not get bsod?
Update: i noticed i did not have it disabled, so maybe sometime i will try again with it disabled to see if system is able to wake up

@zcorn2017 May be I'll try it on windows 11, this really bugs me out. Stuck to using hibernation
