To connect a Logitech wireless mouse to a Lenovo laptop, first ensure the mouse is powered on and has fresh batteries. If your mouse uses a USB receiver (dongle), insert it into an available USB port on your laptop—most systems recognize it automatically within seconds. If your mouse uses Bluetooth, enable Bluetooth on your laptop through Settings or the system tray, then press and hold the pairing button on the mouse (usually on the bottom or side) until the LED flashes. Your laptop should detect the mouse in the Bluetooth menu; select it to complete pairing. Some Logitech mice require the Logitech Options or Logi Options+ software for full functionality—you can download this from Logitech's website and install it on your laptop for additional features like customizable buttons and sensitivity adjustments. After connection, test the mouse by moving it across your screen and clicking. If the mouse doesn't respond, verify batteries aren't depleted, try removing and reinserting the USB receiver, or restart your laptop. For Bluetooth mice, ensure your laptop's Bluetooth is fully enabled and try re-pairing if the initial connection fails. Most Logitech wireless mice work with all Windows and macOS versions without additional drivers, though having the optional software enhances functionality and troubleshooting options.
