I recently discovered this error on my computer too. PS/2 keyboard and mouse error 24 while using a USB keyboard and mouse. It seems this error is quite common on many computers... but how to fix it without much fuss is what I wanted... and I did find an answer. It actually works. The problem is Windows has legacy support for older hardware... like the PS/2 keyboard and mouse. These require a process called i8042prt.sys to correctly load up drivers. My computer has these PS/2 ports on its back side and windows loads up the drivers for them when it boots... allowing any PS/2 hardware to work if you have it. But I don’t have PS/2 hardware. Windows just hides the error 24 message in the device manger for missing hardware that’s not installed.
Modding a registry entry will fix this. i8042prt.sys has 6 different run settings. They are 0-5. The default is 3 allowing the PS/2 driver to be in a standby mode just waiting for a PS/2 to be used. 0,1and 4 will generate an unhidden error 24 for keyboard and mouse. 2 and 3 generates the hidden error 24... but 5 does not generate an error message... the PS/2 device is now shown as being active but with no drivers running and no error messages.
I’ve seen a lot of internet posts on this subject with no real answers. This one definitely works.
If the BIOS could disable the PS/2 ports, that might work too, but my computer doesn’t have that ability.
