Title:
[ThinkPad E14 Gen2] Closing the lid does not trigger system suspend
Status in linux package in Ubuntu:
Confirmed
Bug description:
According to the system settings (see the attached screenshot), the
laptop should go to sleep (suspend to RAM) when I close the lid.
However, closing the lid has no visible effect.
'systemctl suspend' works OK, choosing 'Leave' -> 'Sleep' in the menu
works too.
After suspend and resume, closing the lid starts working as expected
and is triggering suspend to RAM. So this might be related to BIOS,
ACPI or something similar.
I am filing this bug against 'linux' package because, perhaps, a quirk
could be added in the kernel as a workaround. IIRC, the kernel had a
number of quirks to work around BIOS/ACPI problems.
A similar issue exists with Fn keys on this machine: they do not work
after a boot but start working after I have suspended and resumed the
system (checked with Fn+F5/F6 - brightness down/up). Others
encountered that too (see [1], [2] below). I suspect it is caused by
the same bug in BIOS or ACPI.
ThinkPad E14 Gen2 with AMD Ryzen 5 4500U
Machine type model: 20T60030RT
UEFI BIOS ver: R1AET33W (1.09), the latest version at the moment
Embedded controller FW ver. R1AHT33W (1.09)
SecureBoot: off
OS: Ubuntu 20.10 amd64
Kernel 5.8.0-40-generic.
I have also tried the builds of the newer mainline kernels:
* 5.9.0-050900-generic from
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9/amd64/
* 5.10.0-051000-generic from
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10/amd64/
The issues with lid closing and Fn keys show up there too.
