I can confirm that qubes 4.0.4 is working out of the box on the Lenovo ThinkPad L14 with the Ryzen 7 PRO 5850U processor.

What i can confirm is working:

  • Keyboard brightness control
  • ACPI volume control and mute
  • FN-lock/FN-lock indicator
  • Capslock/Capslock indicator
  • Mousepad
  • Trackpoint
  • ACPI display menu
  • Webcam
  • Microphone
  • Power control
  • Temperature/fanspeed sensors
  • Fanspeed is regulated as expected
  • Ethernet
  • µSD reader
  • Integrated speaker/Headphones (switches as expected)

If have not tested (yet):

  • LTE module
  • Bluetooth module
  • Smartcard reader
  • Infrared camera
  • Dock
  • Fingerprint reader
  • DisplayPort over USB-C
  • Tamper detection

There are some minor restrictions:

  • Integrated wifi module not working
  • Screen brightness control not working
  • rfkill ACPI Event not working
  • Hibernation not working
  • Suspend-to-RAM not working
  • HDMI out not working

In case you are wondering about the battery life:

  • Screen running, full brightness, 4 qubes idling: 3:20 h
  • Netflix FHD streaming, full brightness, wifi, 7 other qubes idling: 2:00 h

My few performance metrics:

  • Boot time: 59 seconds
  • Whonix-ws-16-dvm creating/opening: 7.5 seconds
  • 8 core mkp224o qube does around 16 mio keys/s with one filter

Things worthy of note (at least to me)

  • Captive screws
  • Additionally shielded module bays and RAM slots
  • Thermal design routes heat around the battery
  • Screen gets notable blackbleed temporarily while closing/opening the lid
  • Screen is embedded in plastic shell, not thin flexible tape
  • Sliding webcam cover only covers the normal camera, not the IR one
  • There is a tamper detection feature

I suspect that these would be more than just minor restrictions for most users.

Are you sure this laptop has 3 controllers, not just 3 USB ports connected to the same controller?

Thanks for your report!
