Lenovo 4Y51J62544 Professional Bluetooth Rechargeable Ergonomic Mouse

Overview

The Lenovo 4Y51J62544 is a six-button Bluetooth 5.1 ergonomic mouse built for professionals who spend long days at a workstation and need a peripheral that keeps pace without constant trips to the charging cable. At 96 grams, it sits light in hand without feeling flimsy, and the Storm Gray finish resists the visual wear that cheaper plastics show after a few weeks of daily use. Blue optical tracking at up to 4000 dpi means the cursor responds to intent rather than fighting you — a real factor if you're switching between a dense multi-monitor layout and a single laptop screen throughout the day.

Bluetooth 5.1 with Bluetooth Low Energy support keeps pairing reliable and connection latency low across Windows 10 and Windows 11 environments. There's no USB dongle required, which matters in locked-down enterprise deployments where adding a receiver to every workstation creates an inventory and security headache. A single USB Type-A port on the receiver side handles charging via the included USB-C cable, so you're not sourcing proprietary adapters when the cable eventually walks off.

Key Features

• 4000 dpi Blue Optical Sensor: Four sensitivity levels let you dial in tracking for high-resolution displays or precision CAD work without toggling through software — the sensor reads intent accurately even on glass-like desk surfaces where cheaper optical sensors stutter.
• Bluetooth 5.1 with BLE: Bluetooth Low Energy compatibility keeps the connection alive without draining the battery for standby overhead. In practice, this extends the advertised three-month battery life rather than undermining it, and pairing latency on reconnect is negligible.
• 3-Month Battery Life (Lithium): A built-in lithium cell rated for up to three months on a charge means you're not swapping AA batteries mid-quarter. The USB-C charging cable is included — one less consumable to stock.
• Six Programmable Buttons: Beyond left, right, and scroll-click, the additional buttons handle back/forward navigation or application-specific shortcuts, reducing hand travel to the keyboard during document review or browser-heavy workflows.
• 2-Direction Scroll Wheel: Vertical scrolling handles the obvious; horizontal tilt scrolling through wide spreadsheets or panoramic CAD drawings keeps your wrist off the trackpad and your focus on the work.
• Click Durability Rated at 3 Million Clicks: At 200 clicks per working hour across an eight-hour day, that's over 1,800 days of rated mechanical life — long enough that this mouse will likely outlive the workstation it ships with.
• Ergonomic Form Factor at 96g: Light enough to avoid fatigue over a full shift, shaped to reduce wrist pronation. At 129mm long and 72mm wide, it fits a medium-to-large hand without crowding fingers on the side buttons.
• Operating Range 0–40°C: Rated for standard office and light industrial environments — server room cold aisles and warehouse floors near the upper limit are covered, though extended exposure to industrial heat or freezer environments would push past spec.

Integration & Compatibility

The 4Y51J62544 is validated for Windows 10 and Windows 11. Bluetooth 5.1 pairing works with any host equipped with a compliant Bluetooth adapter — no proprietary software stack required for basic operation, though Lenovo's device management utilities can enable button remapping and DPI customization on supported platforms. The USB Type-A charging port is compatible with standard USB-C to USB-A cables; the included cable handles charging without needing a dedicated power brick.

For enterprise IT environments, the lack of a USB dongle simplifies deployment: no receiver inventory to track, no USB port consumed on the workstation, and no conflict with USB lockdown policies that restrict unrecognized HID devices. Bluetooth device enrollment through Windows Bluetooth management tools applies normally. Compliance certifications include FCC, CE (via VCCI, CB, KCC, ICES, BQB, cTUVus, CEC, NCC, RCM), RoHS, and UN38.3 for lithium cell transport — relevant for large procurement orders that cross international shipping lanes. IEC 62133-2:2017 and EU REACH compliance round out the regulatory picture for European deployments.

Frequently Asked Questions

Q: What operating systems does the Lenovo 4Y51J62544 support?

A: The 4Y51J62544 is validated for Windows 10 and Windows 11. Basic Bluetooth HID functionality may work on other Bluetooth 5.1-compatible hosts, but Lenovo's official support is scoped to those two Windows versions.

Q: Does the 4Y51J62544 require a USB dongle or receiver?

A: No. It connects via Bluetooth 5.1 directly to the host device's Bluetooth adapter — no USB receiver or dongle is required. The USB Type-A port on the mouse is used exclusively for charging via the included USB-C cable.

Q: How long does the battery last, and how is it charged?

A: The built-in lithium battery is rated for up to three months per charge under typical use. It charges via the included USB-C cable connected to any standard USB Type-A port — no proprietary charger or power brick needed.

Q: What is the warranty on the Lenovo 4Y51J62544?

A: Lenovo covers the 4Y51J62544 under a 3-year limited manufacturer warranty.

Q: Is the 4Y51J62544 compliant with FCC and RoHS regulations?

A: Yes. The mouse carries FCC, RoHS, CE, VCCI, BQB, cTUVus, CEC, NCC, RCM, CB, KCC, ICES certifications, along with IEC 62133-2:2017 for the lithium cell and EU REACH compliance — covering North American, European, and Asia-Pacific regulatory requirements.

Q: What DPI levels does the 4Y51J62544 support, and can they be adjusted?

A: The sensor supports up to 4000 dpi. DPI adjustment is available through Lenovo's device management software on supported Windows platforms; the number of selectable levels and step increments depend on the software version installed.

What stands out about the 4Y51J62544 in enterprise procurement is the three-month lithium battery life paired with dongle-free Bluetooth 5.1 — two things that separately reduce IT overhead, and together make a meaningful difference when you're rolling out peripherals across a few hundred desks. No receiver inventory, no AA battery replacement schedule, and no USB port consumed on locked-down workstations.

Technical Highlights:

• 4000 dpi Blue Optical Sensor: Covers everything from standard 1080p single-monitor work to 4K multi-display setups without forcing a DPI compromise. Blue optical tracking is more forgiving on varied desk surfaces than red laser alternatives at this price tier.
• 3 Million Click Durability Rating: At realistic office click rates, that's well over five years of mechanical life — longer than most device refresh cycles, which means this peripheral can follow the user through a workstation upgrade without replacement cost.
• Bluetooth Low Energy (BLE) Compatibility: BLE keeps the idle power draw minimal, which is what makes the three-month battery claim credible in real-world use rather than just lab conditions. Connection resume on wake is fast enough that users won't notice the difference from wired.

Deployment Considerations:

• Validated OS support is Windows 10 and Windows 11 only — if your environment runs any Linux-based thin clients or macOS endpoints, basic HID pairing may function but is outside Lenovo's tested scope; verify before committing to a large order.
• The operating humidity floor is 20% — low-humidity environments like some data center floors or dry-climate offices during winter heating season could push below spec; a minor consideration for single-room deployments but worth noting in arid-region facilities.

The 4Y51J62544 is a practical fit for Windows-standardized office deployments where IT wants to minimize peripheral support tickets — the long battery cycle, dongle-free pairing, and three-year warranty coverage make it a low-maintenance choice for knowledge worker rollouts.
