Hi,I'm sorry about the issue. What's the model of your Gateway laptop? Please check at the back/bottom of the laptop.Can you please confirm the Gateway laptop has windows 7? (Or another version, such as windows xp, vista, or 7, or 8, or 10, etc.?)
Is the keyboard currently working on the laptop?
If you connect a USB mouse (a desktop usb mouse) to the laptop, does it work?Please reply at the box below. Thank you.
