Lenovo 4X31S04810 Wireless Multi-Mode Pro Combo Keyboard and Mouse

Overview

The Lenovo Wireless Multi-Mode PRO Combo Keyboard and Mouse 6000 — part number 4X31S04810 — is a dual-mode wireless desktop set built for professionals who move between workstations, shared desks, or multi-device setups without wanting a tangle of USB receivers or Bluetooth pairing headaches. It connects via both 2.4G wireless (USB-A receiver) and Bluetooth 5.3, giving you a practical fallback if one connection path is occupied or unavailable. The Eclipse Black colorway and full-size 3-zone keyboard layout make it a functional fit for enterprise desktops and computer peripherals refresh programs alike.

Key Features

• Dual Wireless: 2.4G + Bluetooth 5.3: Switching between a USB-A receiver connection and BT 5.3 means you can pair to a desktop via the dongle and a laptop or tablet via Bluetooth simultaneously — no re-pairing when you switch contexts. BT 5.3 also gives you a more stable, lower-latency link than older Bluetooth standards in RF-dense office environments.
• 36-Month Battery Life: Up to 36 months on a single battery charge cycle is a meaningful operational benefit for large deployments — fewer interruptions, lower battery replacement overhead across a fleet. If you're managing a 50-desk rollout, that's a measurable reduction in help-desk battery tickets.
• 3-Zone Full-Size Keyboard Layout: The 3-zone layout (main alphanumeric, function row, numpad) at 433.6 mm × 123.4 mm keeps the full productivity surface intact. Key pitch is 19.05 mm in both X and Y directions — standard desktop spacing, so touch typists won't need to re-learn muscle memory when transitioning from a wired board.
• 10 Million Keystroke Lifecycle: Rated to 10 million keystrokes per key, this combo is built for sustained daily use rather than light occasional input. For call-center agents, data-entry operators, or warehouse office staff logging high keystroke volumes, that rating translates directly to lower replacement frequency.
• 8-Button Mouse with 3-Stage DPI: The mouse ships with 8 buttons (Left, Right, Scroll wheel, Scroll Left/Right tilt, DPI toggle, Power, Pairing) and three DPI settings — 1,600, 2,400 (default), and 4,000. The DPI toggle is on-device, so users can switch sensitivity without software. 4,000 DPI covers high-resolution multi-monitor setups without excessive hand movement.
• 4-Way Scroll Wheel: Horizontal scrolling (left/right tilt on the scroll wheel) is genuinely useful in wide-spreadsheet or CAD-drawing workflows — you're not reaching for a scroll bar every time you need to move laterally across a large dataset.
• 5 Million Click Button Life (Left/Right): The primary mouse buttons are rated to 5 million clicks — meaningful for high-frequency users. Combined with the keyboard's 10 million keystroke rating, the set is spec'd for full commercial shift use rather than light desktop duty.
• IR Mouse Sensor: The IR sensor tracks reliably on most standard desk surfaces without requiring a dedicated mouse pad, keeping desk setups clean and reducing per-station accessory cost.

Integration and Compatibility

The 4X31S04810 is validated for Windows 10 and Windows 11 and requires a USB-A port for the 2.4G wireless receiver. Bluetooth 5.3 pairing covers additional devices without consuming a USB port. No proprietary driver software is required for core functionality — plug-in the USB-A receiver and the keyboard and mouse are immediately operational. The combo is OS-limited to Windows per evidence; confirm compatibility before deploying to Linux or macOS environments. The Lenovo peripheral lineup this combo sits in is aimed squarely at the commercial Windows desktop market.

Operating environment: rated 20%–95% relative humidity (non-condensing) and up to 40°C / 104°F maximum operating temperature — well within typical office and light industrial conditions. For deployments in temperature-controlled server rooms or standard office environments, those environmental limits are a non-issue. If your installation area runs hotter than 40°C (some equipment rooms without adequate cooling), account for that before spec'ing this combo.

Hardware requirement is simply a PC with a USB-A port for the receiver. The US English layout (QWERTY) is the configuration shipped under this part number — verify the language layout matches your end-user requirement before ordering. For a broader look at wireless keyboards and mice, compare this against models targeting specific ergonomic or travel use cases depending on your deployment profile.

Frequently Asked Questions

Q: What wireless connection modes does the 4X31S04810 support?

A: The 4X31S04810 supports two wireless modes: 2.4G wireless via a USB-A receiver, and Bluetooth 5.3. Both can be used independently, allowing you to pair the combo to different devices simultaneously.

Q: What operating systems are compatible with the Lenovo 4X31S04810?

A: Per Lenovo's published specifications, the 4X31S04810 is validated for Windows 10 and Windows 11. Compatibility with Linux or macOS is not confirmed in the available evidence.

Q: How long does the battery last on the Lenovo 6000 keyboard and mouse combo?

A: Battery life is rated up to 36 months under typical use conditions. This applies to the combo set as a whole — exact duration per device will vary with usage intensity.

Q: What DPI settings are available on the mouse?

A: The mouse supports three DPI settings: 1,600, 2,400 (default), and 4,000. The DPI toggle button is on-device — no software required to switch between settings.

Q: What is the warranty on the 4X31S04810?

A: Lenovo covers this product under a 3-year Customer Replaceable Unit (CRU) warranty.

Q: What is the key pitch on the keyboard?

A: Key pitch is 19.05 mm in both the X (horizontal) and Y (vertical) directions — standard full-size desktop spacing.

When evaluating the 4X31S04810 for a commercial desktop refresh, the spec that stands out immediately is the 36-month battery life combined with dual-mode wireless (2.4G + BT 5.3). In a managed desktop environment where IT is handling dozens or hundreds of units, battery replacement cycles are a real operational cost — and 36 months buys you a full budget cycle before you're sourcing replacements at scale. The keyboard and mouse lifecycle ratings (10 million keystrokes, 5 million mouse clicks) back up the idea that this combo is spec'd for sustained daily commercial use, not light-touch occasional input.

Technical Highlights:

• Dual-Mode Wireless (2.4G + BT 5.3): The USB-A receiver handles the primary workstation connection while BT 5.3 pairs to a second device — a laptop, tablet, or secondary monitor system — without pulling a second USB port. Useful in hotdesk and shared workstation setups where the receiver stays in the desk dock permanently.
• 3-Stage DPI (1,600 / 2,400 / 4,000): On-device DPI switching without software means the combo works out-of-box in locked-down enterprise environments where driver installation is restricted by group policy. The 4,000 DPI ceiling covers dual 4K display setups without excessive mouse movement.
• 19.05 mm Key Pitch (X and Y): Standard pitch in both axes means no adaptation period for users transitioning from any conventional full-size keyboard. At 433.6 mm wide, the full-size layout with numpad is intact — relevant for finance, data entry, and any role where numpad access is part of the daily workflow.

Deployment Considerations:

• The combo requires a USB-A port for the 2.4G receiver — confirm your workstation dock or tower has an available USB-A port if the environment is heavily loaded with USB peripherals. USB-C-only thin clients will need a hub.
• Windows 10 and Windows 11 are the validated OS environments per Lenovo's spec sheet. Do not assume plug-and-play on Linux distributions or macOS without independent testing — this is a Windows-targeted product.

This combo is a practical fit for large-scale enterprise desktop refresh programs where IT needs a low-maintenance, long-battery wireless input set that works without software installation — call-center floors, open-plan offices, and hotdesk environments are the natural home for the 4X31S04810.
