Laptop Displays Numbers When I Type Letters

The space-saving design of some laptop keyboards can cause confusion when little-known options are accidentally enabled.
When I press certain letter keys on my laptopβs keyboard, it prints numbers instead! How can I fix this?
Although this may seem odd, there is actually nothing wrong with your keyboard. Your number lock is on β press the Num Lock key once to turn it off, and your keyboard will resume operating normally.
Space is at a premium on a laptop keyboard, so they do not feature the number pad that is usually found on the right side of a full-size keyboard. Instead, some of the letter keys double as number keys. When the number lock is on, those letter keys behave in the same way that the number pad behaves on a full-size keyboard.
Take a look at the keyboard pictured above. Notice how the βKβ key also says β2β, and the βLβ key also says β3β. When number lock is on, pressing βKβ will output β2β, and pressing βLβ will output β3β.
