Sleep problem on Redmibook Pro 14 2022 Intel (12650h) #91
Comments
I have the same issue on a Redmibook Pro 15S AMD (RMACZ5B0P0909). Did you find a fix? |
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? |

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)
osi=! osi=Linux
,osi=! osi=Windows 2015
,acpi_backlight=native\video\vendor
);sysfs
after resume;acpi_exec
(calling_BCM
method);Sometimes laptop resumes correctly (one time of 10-20).
Do you have any ideas where the bug could be? I'm really in stuck.
