How i can enble function key - HP 4440s Probook

HP laptops have the ability to lock the blue special function keys on, making numerical data entry easier on laptop models that do not have the room for dedicated numerical keypads. Because the key combination to lock the function keys is so simple, however, it is easy for those who wouldn't normally use this ability to do so accidentally. When the function keys are locked, pressing certain keys will result in numbers being typed rather than letters. Unlock the function keys to alleviate this issue.

Press the "Fn" and "Num Lk" keys on the keyboard simultaneously. The "Number Lock" indicator light should turn off, indicating that the letter keys will once again type letters when pressed. This combination should work on the majority of recent HP laptops. If it does not, try one of the alternate key combinations in this article's remaining steps. Press the "Fn" and "F11" keys simultaneously, then attempt to type a letter. If the combination does not work, continue to the next step. Press the "Fn" and "Scroll Lock" keys simultaneously, then attempt to type a letter. Continue to the next step if this does not work. Press the "Fn," "Scroll Lock" and "F11" keys simultaneously.
