Integrated Keypad is not working in Ubuntu OS

[Arpan Jain]

we've encountered an issue with the keypad when booting the device with Ubuntu OS. We have tested two versions (22 and 24), but in both cases, none of the keypad keys are functioning. The keypad works fine in the BIOS utility setup page.We have also attempted to upgrade the kernel to version 6.11 from the default kernel versions provided, but this did not resolve the issue.

cat /proc/version_signature > version.log ->no output

sudo lspci -vnvn > lspci-vnvn.log ->no output

xev ->no output
