My 730's keyboard started acting up mid January. I didn't mind it and dealt with it. I do light gaming and the keyboard seems to have grown a large delay. Only when I am gaming. I check Task Manager and my RAM usage is at 60-70%. Disk around 39%. CPU not maxed out neither iGPU. What happens is when I am to press a key such as F when i press it it happens later and it starts to stack the commands. So if i press F once it will finish the input around 1- 0.5sec later. I've looked everywhere, I can't seem to find any solutions. I have FilterKeys disabled so thats not it. Backlight is off and FPS is capped to 60 same as my screen 60hz. Only keyboard, mouse entries are smooth and with no lag. It would be very helpful if someone could help.

What happens if you disable the onboard keyboard but leave the external keyboard enabled?

Which would it be the HID Keyboard or the PS/2 Keyboard
The HID says located on Lenovo Pen device which I do not own
PS/2 says on keyboard slot
But when I go to disable it, while opening it as admin it is grey boxed like this:

You can uninstall it, just don't reboot as it'll reinstall next boot. The reason for this is to determine if something's stuck on the built-in keyboard. A quick alternate test is to rotate the 730 into tablet mode, which should automatically disable the keyboard. Then see if you have the same experience with the virtual, on-screen keyboard.
I've experienced this many times and, for me, it always turns out to be a stuck key or something under one of the non-letter keys, such as Scroll Lock or some such. Sometimes, a little compressed air is all it takes. Other times, the keyboard needs to be replaced.
Have you tried booting into Safe Mode? Some other options here, but ignore the ads for software.
