The Lenovo 4X31N50708 is a wireless keyboard and mouse combo built for people who want a reliable desktop setup without extra cables. It connects through a 2.4 GHz USB receiver, so you can plug in once and start working on a laptop or desktop in an office, classroom, or living room.
The keyboard follows Lenovo’s 2.5-zone layout. You get a familiar full-size set of keys, plus a number pad and one-touch media shortcuts for quick volume or playback changes. Key switches are tuned for quiet operation, which helps during late-night work sessions or shared offices. The deck resists small spills and has adjustable tilt feet, letting you choose a flat or angled position.
The mouse pairs naturally with either hand. A 1600 DPI optical sensor delivers smooth tracking across typical desk surfaces, so you can edit documents, browse the web, or line up spreadsheet cells with confidence. Both devices arrive with batteries installed; the keyboard can run for up to 15 months and the mouse for about 18 months before replacements are needed.
Durability matters if you type all day. The keyboard is rated for about 10 million key presses and the mouse for roughly 3 million clicks. Lenovo also uses 65 percent post-consumer recycled plastic in the housing, reducing environmental impact. A three-year limited warranty backs the combo, offering extra reassurance for business deployments or long-term home use.
