ACPIPatcher: S0ix disabler
This EFI application lets you to disable Windows Modern Standby / Connected Standby / S0 Sleep on ANY platform.
Dell's Modern Standby SUCKS!
This repo does exactly the opposite to the original repo. Great thanks to @imbushuo.
This simple UEFI application patches your ACPI table to force disable S0 Low Power State (aka. Connected Standby) regardless of platform configuration. Currently you have to run it every time before booting into Windows.
Notes
Microsoft reported that
Please note that Windows do not support seamless transition between ACPI S3 and S0ix. A
fresh installation is required.
But, before Win 10 20H1 update, you can simply disable S0 and use S3 by setting CsEnabled=0 in the register.
However, Microsoft has blocked it since Win 10 20H1 update.
Prerequisites
- Visual Studio 2017 or gcc/make
- git
Sub-Module initialization
For convenience, the project relies on the gnu-efi library, so you need to initialize the git submodule either through git commandline with:
git submodule init
git submodule update
Or, if using a UI client (such as TortoiseGit) by selecting Submodule Update in the context menu.
Compilation and testing
Just build project in Visual Studio.
Visual Studio 2017 and ARM/ARM64 support
Please be mindful that, to enable ARM or ARM64 compilation support in Visual Studio 2017, you MUST go to the Individual components screen in the setup application and select the ARM/ARM64 compilers and libraries there, as they do NOT appear in the default Workloads screen:
You also need to ensure that you have Windows SDK 10.0.14393.0 or later installed, as this is the minimum version with support for ARM64.
Usage
First, you need to install rEFInd.
Then, put the binary to /EFI/refind/drivers_{arch} and it should work.
Known issues
Secure boot no longer works. However, you may find some workaround but personally, I don't recommand it. Simply disable Secure Boot in your BIOS should be fine. Bitlocker also works.
