Hi everyone. I'm dealing with a very frustrating power management issue on my laptop and I'm hoping someone here has a clue or has managed to fix it.

The Setup:

Model: Huawei Matebook D15

CPU: AMD Ryzen 7 5700U with Radeon Graphics

OS: Windows 11

The Problem:

When the laptop goes to sleep (either by idle timeout or closing the lid), it completely refuses to wake up. When I try to wake it (opening the lid or pressing a key), the screen stays completely black. The keyboard backlight or the Fn key light flashes as if it's trying to boot, but it just stays stuck in this coma state.

The only way to use it again is by holding the power button for 10 seconds to force a hard shutdown. Since I usually have heavy dev environments and databases running in the background, these constant hard resets are putting my projects at risk of corruption.

(I've attached a video showing exactly how the screen and keyboard behave).

I did a factory reset back in February and everything worked fine for a couple of months, but the issue came back recently (I strongly suspect a Windows Update broke the power management compatibility).

What I've ALREADY TRIED (without success):

Basic Power Settings: Disabled "Fast Startup" in Control Panel and unchecked "Allow the computer to turn off this device to save power" for the Wi-Fi adapter.

Forcing S3 Sleep: Modified the Windows Registry (PlatformAoAcOverride to 0) to disable Modern Standby (S0). This only caused the laptop to shut down/hibernate entirely and not wake up upon opening the lid. I had to revert it.

Driver Rollback: Tried rolling back the AMD Radeon driver from Device Manager and picking older local drivers, but the saved versions still cause the same crash.

Huawei PC Manager: Checked for BIOS, Firmware, and Chipset updates directly through Huawei's official tool. Everything claims to be "up to date."

Direct AMD Drivers: As a last resort, I used the official "AMD Auto-Detect and Install" tool to get the latest, cleanest versions of the AMD Radeon Graphics and AMD Ryzen Chipset drivers directly from the source. The problem persists completely.

Currently, my only workaround is setting the laptop to Hibernate when I close the lid, but I would really like to get normal Sleep mode back.

Has anyone dealt with this level of incompatibility between Windows 11, Ryzen, and Huawei's BIOS? Is there a patch or an obscure low-level setting I'm missing?

Any help is greatly appreciated!
