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.
