After many hours of tinkering, I finally found a way to fix ACPI S4 Hibernation (hibernatemode 25) on the i5 Surface Pro 7 on macOS 13.6.7 Ventura, 15-Inch i7 Surface Laptop 3 on macOS 14.5 Sonoma, i5 Surface Laptop Go 1 on macOS 13.6.7 Ventura and very likely on the Surface Book 3 (untested) as well. ACPI S3 Sleep (hibernatemode 0) is still broken, though, but perhaps the Hibernation fix will lead the way to a full S3 Sleep fix at some point in the future.

The key to the fix is to enable ACPI S3 Sleep in the DSDT. This is actually very easy and I'm stunned nobody tried this before. Searching for _S3 in the DSDT.aml file leads us to this:

    If (SS3)
    {
        Name (_S3, Package (0x04)  // _S3_: S3 System State
        {
            0x05, 
            Zero, 
            Zero, 
            Zero
        })
    }

So to enable _S3, SS3 needs to return One. Now searching for SS3 leads us to this:

    Name (SS1, Zero)
    Name (SS2, Zero)
    Name (SS3, Zero)
    Name (SS4, One)

Enable ACPI S3 Sleep

Change Name (SS3, Zero) to Name (SS3, One) to enable ACPI S3 Sleep with the following ACPI patch in ACPI -> Patch:

Comment: Rename Name (SS3, Zero) to One - Enable S3 Sleep
Find: 5353335F00
Replace: 5353335F01

Before the rename, the system log shows:

(AppleACPIPlatform) ACPI: sleep states S4 S5

After the rename, the system log shows:

(AppleACPIPlatform) ACPI: sleep states S3 S4 S5

and commands such as pmset -g log or pmset -g log | grep -e "Sleep.*due to" -e "Wake.*due to" now clearly show that the device is entering sleep and (eventually) waking up from sleep.

Add Reserved Memory region

This fix was found in Tyler Nguyen's x1c6-hackintosh repo. Thank you @benbender @1Revenger1 @savvamitrofanov and @vit9696!

Get rid of the black screen on Wake with the following Reserved Memory region in NVRAM -> ReservedMemory:

Comment: Fix hibernate mode 25 black screen on wake
Address: 569344
Size: 4096
Type: RuntimeCode
Enabled: true

Enable DiscardHibernateMap

This doesn't seem to be required on every Surface device, but at least on the Surface Laptop 3, it fixes a kernel panic on Wake.

Enable the following Booter Quirk in Booter -> Quirks:

DiscardHibernateMap=true

Set HibernateMode to NVRAM

In Misc -> Boot, set HibernateMode to NVRAM:

HibernateMode=NVRAM

I would also recommend enabling HibernateSkipsPicker in Misc -> Boot:

HibernateSkipsPicker=true

Add the GPRW instant wake patch

At least on the Surface Pro 7 and the Surface Laptop Go 1, the GPRW instant wake patch is required as well.

Add SSDT-GPRW.aml to the ACPI folder of your EFI. Then add SSDT-GPRW.aml to ACPI -> Add and the following ACPI patch to ACPI -> Patch in the config.plist file:

Comment: Change Method(GPRW,2,N) to XPRW, pair with SSDT-GPRW.aml

Replace: 5850525702

Enable hibernatemode 25 in macOS

Open the Terminal and enter the following commands, then reboot for the changes to take effect:

sudo pmset restoredefaults
sudo pmset -a hibernatemode 25

If for whatever reason Hibernate is still not working on your system, you should reset the Power Management settings and rebuild the sleepimage file. To do so, open the Terminal and enter the following commands, then reboot for the changes to take effect:

sudo rm /Library/Preferences/com.apple.PowerManagement*
sudo rm /var/vm/sleepimage
sudo pmset hibernatefile /var/vm/sleepimage

Once you are back in macOS, disable Sleep and enable Hibernate again, then reboot:

sudo pmset restoredefaults
sudo pmset -a hibernatemode 25

Fix broken Bluetooth on Wake from Hibernation

After the device wakes up from Hibernation, Bluetooth may be broken / unable to connect.

A very simple fix for this issue is to download and install Bluesnooze. Launch the app, enable Launch at login and you're done!

A few comments / Help needed!

Hibernation seems to be working perfectly on my i5 / 8GB / 256GB Surface Pro 7 and i5 / 8GB / 256GB Surface Laptop Go 1 both running on macOS Ventura 13.6.7 with the SMBIOS MacBookAir9,1 and using Xiashangning's BigSurface.kext v6.5. Everything comes back online after waking up from hibernation.

However, my i7 / 16GB / 2TB WD SN770M 15-Inch Surface Laptop 3 running macOS Sonoma 14.5 with the SMBIOS MacBookPro16,2 and with Xiashangning's BigSurface.kext v6.2 wakes up with a dead trackpad. I have yet to find a way to fix the dead trackpad.

The main difference between the Surface Pro 7 or Surface Laptop Go 1 and the Surface Laptop 3 or Surface Book 3 is that on the former, the keyboard and trackpad are attached through USB, whereas on the latter, they are attached through a proprietary interface.

Both the Surface Laptop 3 and the Surface Book 3 are plagued by a nasty issue with the trackpad on macOS. Fixing the issue is possible, but requires downgrading the firmware to 13.101.140.0 and BigSurface.kext to 6.2, that's why it still runs with BigSurface.kext v6.2. The trackpad works with the latest BigSurface.kext v6.5, though, but the trackpad lags and skips every few seconds. Furthermore, tests show that the BigSurface.kext v6.5 doesn't fix the dead trackpad after wake from hibernation.

Playing around trying to unload the BigSurface.kext or VoodooSerial.kext plug-in before hibernate and reloading it on wake from hibernate has been a dead end until now, as I'm unable to do so due to various errors with the kextstat, kextunload and kextload commands in macOS.

So, the first steps to troubleshoot the trackpad issue would be to downgrade macOS to 13.6.7 Ventura and change the SMBIOS back to MacBookAir9,1, but I must admit I'm not all too confident that would fix the dead trackpad after wake from hibernation. We would probably need to find someone who is able to fix the BigSurface.kext and I'm not sure Xiashangning is still maintaining his BigSurface repo, as there hasn't been any activity for over a year now, since July 14th 2023.

Man, you are amazing! Thank you so much for your work and detailed instruction!

[jlempen]

@jc-bao, thanks for the heads-up! Please check that this fix works on your setup as well. We will try to find a fix for the dead trackpad after wake from hibernation once we know hibernation is working for you as well. I posted the fix on the BigSurface repo as well, perhaps a few other Surface Laptop 3 and Surface Book 3 users might chime in with interesting information about the matter.

[jc-bao]

@jlempen Thank you so much for your amazing work! My current configuration can actually wake the laptop from sleep, but it still draws power from the battery. I will give it a shot tonight.

[jlempen]

@jc-bao It doesn't actually sleep, it only turns off the display and stays idle. That burns about 10% of power per hour... In real S3 sleep, you would loose only 2% over the whole night.

And in Hibernation (hibernatemode 25), it doesn't draw any power, the device is basically turned off.
