If you’re using a laptop (not a Macbook) and you are sure you don’t have a NumLk – one user told that this hack worked for him: if you don’t have both Num Lock or ScrLock hold the FN button down then Alt so you’re holding both down then enter your alt code. How do you type Alt codes without a numpad? When the button turns gray, the number lock is off. Where is the Number Lock key on HP keyboard?Ĭlick on the number lock button, shown as “NLK” just above the number pad on the right side of your on-screen keyboard.
