Hi guys,
when returning form sleep in 90 % of the time the Enter + Backspace key of the internal keyboard of my ThinkPad T14s Gen1 won’t work. This problem persist also through reboots. The keys won’t even work in Bios or Grub.
Sometimes they come back to life but most of the time I need to power down completely.
My Bios is configured for Sleep mode to “Linux”. I cycled through different firmware versions but this problem persists. I’am on kernel Linux fedora 5.13.14-200.fc34.x86_64.
I believe this problem started with a kernel upgrade in the past.
In the beginning I thought this might be related to gnome-shell: 2002925 – Keys not working after standby on Thinkpad T14s Gen. 1
But now I believe it has something to do with ACPI maybe.
Any Idea how I can debug this an collect logs? As long as I attach an external keyboard I can continue working.
Any idea also on how to properly rollback the kernel, so I can verify my feeling?
Best,
eyst
