The Lenovo ThinkPad Bluetooth Laser Mouse connects wirelessly to Bluetooth-enabled computer systems and provides accurate cursor controls. The mouse comes armed with a 1200 dpi resolution sensor and pairs to Windows-based systems using Bluetooth 3.0 technology. For non-Bluetooth systems, an optional USB Bluetooth dongle is required. In addition to the right- and left-mouse buttons, the mouse has a tilting scroll wheel, which enables you to quickly move the cursor up and down as well as left and right while browsing websites or viewing spreadsheets. Furthermore, the mouse is powered via two supplied batteries, and a power management system is on board to automatically switch it into low-power mode when not in use.
