We recently posted about about dealing with laptop liquid spills on keyboards, but another must do thing is to check if all keys in case some keyboard keys don’t work. Test keyboards keys to see if all of them are functioning properly.
PassMark (Link) Test if Keyboard Keys are Working
PassMark Test Keyboard free software allows users to quickly check that all the keys on your computer keyboard are functioning correctly, check the LED keypad, observe the internal scan codes generated by the keyboard and measure the speed of writing.
The up and down movement of each key is registered and highlighted on a graphical image of a keyboard. Each time you press a key on a variety of state information is updated in the window, and the keyboard image. You can type pangram sentences to check the alphabet keys.
