Re: Keyboard goes unresponsive for some reason

I can confirm that this problem still happens on my ThinkPad L14 AMD Gen 1 with firmware 1.29. It has happened extremely often since I started playing videogames in my laptop (multiple key presses at the same time?), but the last one I was just Ctrl+scrolling on a website to zoom out and the Ctrl became softwarestuck. Extremely annoying... If anyone has newer ideas on this issue, please let us know.

├─System Firmware:
│ │   Summary:            UEFI ESRT device
│ │   Current version:    0.1.29
│ │   Minimum Version:    0.0.1
│ │   Vendor:             Lenovo (DMI:LENOVO)
│ │   Update State:       Success

Re: Keyboard goes unresponsive for some reason

i had the same issue 3 times so very rarely, in my case it was always the A key that didn't get released. the only key that works is the power button, which suspends the laptop and after resuming the keyboard functions properly again. i have a ThinkPad P14s Gen3 with the latest 0.1.34 fw. i have a journal saved from the last time this happened. if someone wanna look into i can share it.

Re: Keyboard goes unresponsive for some reason

See whether this also happens w/ a different SW stack (windows, live distro eg. grml) - this might be a "why you should not drink sugary stuff next to your keyboard" situation (or the specific keyboard model might be prone to that) …

Re: Keyboard goes unresponsive for some reason

This just happened to me today (also Thinkpad P14s Gen 3) on 6.1.44-1-lts. I was just scrolling through my journal entries with the 'j' key and suddenly the page just wouldn't stop scrolling even though the 'j' key was released. I can still move my cursor with the touchpad, but the trackpoint stopped working. Activating my browser window with the mouse caused the letter 'j' to be spammed on the address bar, so we can assume that the key press event was being registered even though the key was released. I had to press the power button to reboot.

This occured a few times in the past when I was using the stable kernel (6.4.2-arch). Different keys were affected back then. One time it was the 'a' key, and another time the 'n' key (it was always the last key pressed at the point the problem occured that's affected). The problem disappeared on its own after a few kernel updates past 6.4.2arch. I never noticed it anymore until I recently switched back to the lts kernel.

These are the journal entries around the time the problem occured on 6.1.44-1-lts:

Aug 10 14:51:37 P14s systemd[1]: Unmounted EFI System Partition Automount.
Aug 10 15:03:53 P14s systemd[1]: Starting Cleanup of Temporary Directories...
Aug 10 15:03:53 P14s systemd[1]: systemd-tmpfiles-clean.service: Deactivated successfully.
Aug 10 15:03:53 P14s systemd[1]: Finished Cleanup of Temporary Directories.
Aug 10 15:39:03 P14s systemd-logind[533]: Power key pressed short.
Aug 10 15:39:03 P14s systemd-logind[533]: Powering off...
Aug 10 15:39:03 P14s systemd-logind[533]: System is powering down.

As you can see, I pressed the power key at 15:39. The problem occurred just a minute before that.

Re: Keyboard goes unresponsive for some reason

Issue still occurs on my T14 Gen 3 after upgrading to firmware version 1.28. Interestingly, it seems to have been *caused* by the firmware upgrade, since I had previously upgraded the firmware, magically noticed the glitch was gone, happened to upgrade it again recently, and suddenly noticed the issue is back.

There are a few possibilities here.

1) The firmware devs fixed the issue, then accidentally reintroduced it again.

2) The method I used to install the firmware matters. When I made a bootable disk, the glitch was fixed. When I used fwupd, the glitch was reintroduced.

3) Due to the random nature of this glitch, I just happened to get really lucky for several months, then suddenly get very unlucky over the course of a few weeks

Re: Keyboard goes unresponsive for some reason

I have two brand new ThinkPad L14 Gen 3 AMD - bought for two of my kids for Christmas. Both running Win11 and both fully patched and BIOS updated (via Lenovo's update utility). Both keyboards go unresponsive randomly. Not fixed yet. Waiting for Lenovo to take some responsibility here and fix this.
