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.
