As you know, Laptops are designed with very small and light components to meet the needs of users who are mobile and want to carry them around anytime. Therefore, Laptop keyboards are also minimized and do not have a separate numeric keypad like desktop computers but are integrated with character keys. If users accidentally activate the Num Lock mode during use, typing characters will display numbers, which is the issue you are facing.
The solution is very simple: you just need to turn off the Num Lock mode. Depending on different Laptop models, the Num Lock key may be arranged with other keys or separately. You just need to press the Fn + Num Lk key combination to do this.
Wishing you success!
