Full-Size Wired USB Mouse

The Lenovo 100 is a full-size wired mouse with an ambidextrous shape that suits both left- and right-handed users. It connects through a standard USB-A port on any PC or laptop running Windows and requires no driver installation. The 1000 DPI optical sensor delivers consistent tracking for everyday office tasks and web browsing.

1.7 m Cable and Plug-and-Play

The fixed 1.7 m cable provides enough reach for desktop towers or docked laptops without adding a receiver to manage. Because the interface is plain USB-A, the mouse works immediately on any system that presents a USB-A port — no software bundle, no configuration utility and no battery to charge or replace.

1000 DPI for General Use

At 1000 DPI the sensor handles document editing, email and multi-window navigation smoothly. It is not intended for high-speed gaming or precision design work that demands adjustable sensitivity or higher resolution. Users who need programmable buttons, wireless freedom or on-the-fly DPI switching should look at a different class of device.

Questions about this item

How long is the USB cable on this Lenovo 100 mouse before it might need replacing?

The cable is 1.7 m long and permanently attached; if it frays the whole mouse would need replacement.

Will the 1000 DPI optical sensor keep tracking accurately on glass during long sessions?

Optical sensors at 1000 DPI generally struggle on transparent surfaces, so a mouse pad is recommended for consistent tracking.

Does the wired USB-A connection draw enough power to warm up after hours of use?

The mouse draws minimal power from the USB-A port and stays cool during all-day operation.
