The Lenovo ThinkPad Essential Wireless Mouse (4X30M56887) is a compact tool designed for reliable daily navigation. It connects via a 2.4 GHz wireless link using a small USB nano receiver, which can be stored inside the mouse body to keep it safe while you travel. An optical sensor with a resolution of 1200 dpi ensures smooth tracking across different surfaces, while the three-button layout—consisting of left and right clicks and a scroll wheel—provides the essential controls needed for most tasks. Its black finish is accented by a signature red scroll wheel, maintaining a professional look that fits any workspace. The ambidextrous shape makes it comfortable for both left- and right-handed users, and its lightweight 60 g frame and small dimensions of 106 x 61 x 33 mm allow it to slip easily into a laptop bag. Powered by a single AA battery, this mouse can last up to 12 months, reducing the need for frequent replacements during your work week.
