Introduzione

If your HP ProBook 450 G4 keyboard is being unresponsive, there might be debris underneath the keys or there could be a faulty connection between the keyboard and the computer frame. The easiest way to fix these problems would be to clean the underside of your keyboard with an air compressor or to replace your keyboard. Before using this guide, make sure that the Filter Keys accessibility function is turned off. Sometimes this function can accidentally get turned on which can make it seem like your keystrokes are not being registered. To turn this function off, hold the right shift button for eight seconds, or disable it from the access center in the Windows control panel. If the Filter Keys accessibility function was not turned on, follow the instructions in this guide to safely and properly remove your laptop’s keyboard. Before beginning, make sure to power off your laptop and disconnect it from all power sources.
