Lenovo lasermuisti 3 painiketta USB PS2

The Lenovo Laser 3Button USB PS2 mouse provides precise cursor control through a laser sensor that tracks reliably across a wide range of surfaces. It includes three physical buttons and supports both USB and PS/2 connections, offering compatibility with older and newer systems. The mouse combines a contoured shape for hand support with a durable exterior designed for everyday office tasks and extended use.

Advantages

The laser sensor delivers accurate movement detection and consistent pointer response, reducing jitter on textured or glossy surfaces. Dual-interface connectivity (USB and PS/2) allows straightforward integration with desktop PCs and legacy ports without additional adapters. The three-button layout supports standard left- and right-click actions plus a middle button for scrolling or custom assignments. Its ergonomic profile helps reduce hand fatigue during prolonged sessions, while the solid construction resists wear from daily handling.

• Office productivity tasks such as document editing, spreadsheets and email

How to use

Connect the mouse to an available USB or PS/2 port on your computer; the device is powered and recognized through the cable without the need for external drivers on most operating systems. Place the mouse on a flat surface and move it to control the pointer. Use the left and right buttons for standard clicking functions and the middle button for scrolling or as a programmable input where supported. If connecting via PS/2, ensure the PC is powered off before inserting the PS/2 connector if your system recommends it.

Recommendations

For best tracking performance, use the mouse on a clean, flat surface or a low-pile cloth mouse pad. Keep the sensor area free of dust and debris and avoid using the mouse on reflective glass without a proper pad. When installing on legacy systems, follow the host device instructions for safe PS/2 connection and remove the mouse by gently unplugging the connector when the system is powered off if required.
