Sleep problem on Redmibook Pro 14 2022 Intel (12650h)

Description: On Redmibook 2022 intel edition (14 or 15 inch models, i5-12450h and i7-12650h models) there is a bug: after suspending and resuming there is no screen and keyboard backlight on linux. After resuming using flashlight I can see ssdm screen, fans are working, volume adjust is working too. There are no errors in dmesg. On windows everything is ok. What I have already tried: 0) Different kernels (from 6.1 up to 6.5)

1. Different kernel parameters(osi=! osi=Linux, osi=! osi=Windows 2015, acpi_backlight=native\video\vendor);
2. Trying to adjust brightness through sysfs after resume;
3. Tryint to adjust brighness through acpi_exec (calling _BCM method);
4. Decompinling dsdt\ssdt files, but not errors found. One ssdt table doesn't dump because of wrong header, but I don't think it is the reason of broken sleep;
5. Trying S3 sleep mode (it is avaliable by default on intel models), but after resume system hangs: black screen, althouth keyboard backlight is working.
6. Googling everywhere :) Sometimes laptop resumes correctly (one time of 10-20). Do you have any ideas where the bug could be? I'm really in stuck.

I have the same issue on a Redmibook Pro 15S AMD (RMACZ5B0P0909). Did you find a fix?

[dgefremov]

Nope. I think problem is somewhere deep in SSDT, maybe problems with backlight power supply initialization (due to race condition). So I set up hibernation on lid close event as a workaround, but it is not so comfortable as it could be...

Could you tell me how to set up hibernation on lid close?
