About sleep

[akwangl]

I solved a serious problem with device battery drain after sleep。

Wake up always shows 100%

After waking up, the battery display is always 100%，I had to reboot the computer to get it to display properly to determine the actual power consumption

The amount of power displayed after restarting the computer

Test method

I turned on S3 sleep mode in the AMD extended BIOS

This is the bios bug. It also happens to Linux.
It looks like S3 is not well supported on this laptop.
I made a patch to DSDT to fix this for Linux, but it's not applicable to OpenCore because OpenCore doesn't support DSDT patching.

I'll try adding him to the ACPI

This DSDT is really not in play

[akwangl]

This patch is used to simulate the desktop？

After waking up from s3 sleep, the screen cannot be turned off when closing the lid. Is there any way to fix this problem? It seems to be the same in other systems.

This EFI configuration with the ACPI patch can enable S3 sleep, but connecting a second C port will wake it up instantly.
