Keyboard İssue

[EldarSoltanov]

My caps lock button is not working and when i press alt it reacts like it's fn button (for example when i combine alt+f4 it should close apllications etc. but instead of doing that it turns off/on my keyboard lights  which is combination of fn+f4) 

help pls

edit: i just realized that my pc reacts like im always holding fn all the time

Open Device Manager on your Windows laptop, find the Keyboard option, expand the list, then right-click Standard PS / 2 Keyboard, and then click Update Driver. After the update is complete, test if the keyboard works. If not, the next step is to remove and reinstall the driver.
