## Long description

The Lenovo Laser 3Button USB PS2 mouse provides precise cursor control through a laser sensor designed to track reliably on a variety of common surfaces. It features three physical buttons and an ergonomic shape intended to support comfortable use during extended desktop or laptop sessions. Dual-interface connectivity via USB and PS/2 makes the device compatible with both modern and legacy systems, allowing straightforward plug-and-play setup with minimal configuration.
Advantages
The laser sensor delivers higher tracking accuracy than standard optical sensors, improving pointer responsiveness for typical office tasks and detailed cursor movements. The three-button layout offers simple navigation and basic shortcut control without extra complexity. The ergonomic profile helps reduce hand fatigue during prolonged use. Dual USB and PS/2 connectivity increases compatibility across different computers and docking setups, and the wired connection eliminates the need for batteries and avoids wireless interference.
Suitable for
 General office productivity (word processing, spreadsheets, email)
 Home computer use and web browsing
 Legacy systems and POS terminals requiring PS/2 or USB mice
 Workstations where continuous wired connection and low maintenance are preferred
Key specifications
 Sensor type: Laser tracking for improved surface compatibility
 Buttons: Three physical buttons including left, right and middle/scroll button
 Connectivity: Wired with both USB and PS/2 interface options
 Ergonomics: Right- or ambidextrous-oriented compact shape for extended use
 Power: Bus-powered via host connection (no batteries required)
How to use
Connect the mouse to a compatible computer using the appropriate interface connector (USB or PS/2). On most modern systems, the operating system will recognize the device automatically and make it ready for immediate use; on older systems with PS/2 ports, ensure the computer is powered off before connecting or disconnecting the PS/2 plug to avoid port damage. Position the mouse on a clean, flat surface or mouse pad and use the left and right buttons for standard clicking and selection, while the middle button or scroll function can be used for navigation and opening links in new tabs where supported.
Usage recommendations
For consistent performance, keep the laser sensor area free of dust and debris and use the mouse on a non-reflective surface or a standard mouse pad. When connecting via PS/2, power down the system before making the connection. If pointer speed or button behavior needs adjustment, modify settings in the operating system's mouse control panel to match personal preference and workflow requirements.
