Suspend not working even with s3

[barhom]

Hey,

My ubuntu 20.04 yoga slim 7 amd4800u which I've successfully ran the patch to add s3 suspend is not suspending properly.

Often, either the screen does not turn on.
Or the screen turns on but is frozen.

The only way to recover for me is to turn the laptop completely off and boot again.

Ideas?

Can you post the result of cat /sys/power/mem_sleep and dmesg | grep ACPI:\ \(

[barhom]

➜  ~ cat /sys/power/mem_sleep 
[s2idle] deep

and

➜  ~ sudo dmesg | grep ACPI:\ \(
[sudo] password for barhom: 
[    0.392648] ACPI: (supports S0 S3 S4 S5)

I had forgotten the "=deep" part of "mem_sleep_default".

I think it will work now.

Thanks!
