Cannot use laptop keyboard to wake laptop after kernel 6.5

Hello all,
  As the title states, I have a Lenovo Idepad 14ALC7 and I'm experiencing an issue where if I boot my system up with kernel 6.5 or later, I am unable to wake the device up by pressing the keyboard.
  This was something that was accomplishable in older kernel versions and I have tested by going back and forth between the latest and LTS 6.1 kernels confirming that it is a software thing and not BIOS related.
  Although I did notice a quirk where the older kernel versions I could wake via keyboard but not via trackpad, but >6.5 it's the opposite.
  Far as I can tell it is the keyboard is connected via PS/2 as nothing shows up when I type in lsusb.
  Unfortunately I am unable to simply use an older kernel because the laptop also has a second, much more annoying bug where the NVMe SSD would become unmounted upon suspend and resume basically rendering the machine inoperable.
  It's not the end of the world - I could just wake it via pressing the trackpad - but it's not particularly ergonomic.
