Touchpad not responding

• Look for a touchpad key on the F1-F12 row, or press Fn with it.
• Open Settings > Bluetooth & devices > Touchpad and turn it on.
• Plug in a USB mouse; some laptops turn the touchpad off automatically.
• Clean the pad with a slightly damp cloth.
• Reinstall the touchpad driver in Device Manager.

If none helps, the touchpad cable inside may be loose and needs a technician.
