Lenovo Laser 3-Button USB PS2 Mouse

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.

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.
