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.
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
