AMD Ryzen laptop does not resume from sleep at random

[lejeczek]

Hi guys.

I have a Lenovo E14 Gen2 which sports AMD Ryzen 4500U which 
has recently became very annoying.
I do not shut the system off but, like many other I presume, 
put it to sleep, or system does it automatically.
Resuming is the problem, sometimes. It's third sometimes Nth 
time, previous times it would wake up, where system instead 
of to wake up, freezes.
When it freezes, screens stay blank/black, I have an 
external Dell monitor connected all the time as well as 
external USB ThinkPad keyboard (in case somebody sees the 
same problem in their config). Only power LED changes to 
state saying it's back on, not sleeping.

I wonder if somebody might have any suggestions. My first 
thought was tweaking, adding some kernel parameters but will 
have to research that.

many thanks, L

Hi,

I have a t14s with the same issue. You can try later flavors of the 
mainline vanilla kernel. From the time I started with these the 
frequency went down of this problems occurrence and it still may be less 
than it originally occurred, but it is still present periodically even 
with the current latest version.

It's basically because S3 sleep was removed from the BIOS and instead has a
MS proprietary Si0x or something like that, don't quote me, but the details
are in the link.

It will not likely be fixed anytime soon although there has been some
progress recently. I disabled sleep on my laptop since it boots pretty darn
fast anyway.

Thanks,
Richard
