Hello, 
If I'm not mistaken, this is being tracked in multiple kernel issues, 
https://bugzilla.kernel.org/show_bug.cgi?id=218003 (latest activity) and 
https://bugzilla.kernel.org/show_bug.cgi?id=217873. It seems that this could be 
the same IRQ issue that has been affecting many new laptops. The only success 
I've had is by applying the kernel parameters "i8042.nopnp i8042.direct 
i8042.noloop i8042.dumbkbd" which makes the keyboard work but with an extreme 
input delay. I have also tried building my own kernel with an IRQ patch but 
sadly to no avail. I have the laptop Lenovo IdeaPad Slim 3 14AMN8 so if you 
have a different model you might have more luck than me.

Title:
  Keyboard and Touchpad Not Working in New Lenovo V15 Gen4 Laptop

Status in linux-signed package in Ubuntu:
  Confirmed
Status in linux-signed-hwe-6.2 package in Ubuntu:
  Confirmed

Bug description:
  Hello.

  Ubuntu 22.04.3 with (later upgraded to kernel 6.2.0-32-generic) was
  installed in rewly purchased LENOVO V15 GEN4 AMN (AMD Ryzen 5 7520u)
  laptop and it was noticed that keyboard, touchpad and microphone are
  not working. The keyboard and touchpad work fine in BIOS setup and
  till GRUB (command line). It was found that when external devices such
  as keyboard, mouse and microphone are connected through USB and 3.5
  jack, respectively, these work just fine. To confirm these are not
  hardware problems, Microsoft Windows 11  (Home) was installed in
  another disk partition and observed all these working alright. Hence a
  bug is being reported to draw attention of the concerned team and I
  request them to refer this issue and do the needful at the earliest.
