Pls i need your help what button or combination of button do i need to press? i believe some one can help me out.

Look above the touchpad of your laptop, there is a button there that locks the pointer. Press the button and check if the pointer is moving.

@ Abbott.
In my laptop nothing like key has a shape or any design on it like a pointer.

Thanks for your concerned.

Simply look for any key on your laptop with a symbol of a mouse with a line crossed over it and press the key. It may require you to press it in conjunction with the function key. Or you can check the top left side of your touchpad for a depression, kinda like a hemisphere. double touch it if it exists to unlock your touchpad.
