If someone wants to use a wireless keyboard and mouse with a laptop computer, below are the steps. 
First check if there’s a USB receiver attached to the mouse or keyboard. If there is, see below steps.

1. Turn on bluetooth connection on your laptop.
2. Make sure that batteries are working and turn on both wireless mouse and keyboard.
3. On your laptop, find your wireless mouse and keyboard under bluetooth option and connect the devices. You can now use your wireless bluetooth mouse and keyboard for laptop.
