Lenovo 4Y41R64505 Full-Size Wireless Rechargeable Keyboard with Copilot Key
Overview
The Lenovo PRO Wireless Rechargeable Keyboard (4Y41R64505) is a full-size, 104-key productivity keyboard built for professional PC workstations. It pairs Bluetooth and 2.40 GHz RF wireless connectivity with a rechargeable battery rated for up to three months of typical use — eliminating the recurring cost and interruption of disposable batteries in multi-seat office deployments. The low-profile scissors switch mechanism keeps actuation quiet enough for open-plan environments, and 128-bit AES encryption secures every keystroke over the air.
Key Features
- Dual Wireless — Bluetooth and 2.40 GHz RF: Supporting both connection modes means the 4Y41R64505 works with the included USB Type-A unified receiver for plug-and-play RF pairing, or pairs directly via Bluetooth to systems without a free USB port. For hot-desk environments where workstations cycle between users, Bluetooth keeps the USB ports available for other peripherals.
- Rechargeable Battery — Up to 3 Months Per Charge: A three-month rated battery life means this keyboard won't need attention more than three or four times a year per workstation. That reduces IT consumable costs and eliminates the dead-battery complaints that come with AA-powered keyboards in large office rollouts.
- 128-Bit AES Wireless Encryption: All keystrokes are encrypted at the hardware level — relevant for any environment handling sensitive data entry (financial, healthcare, legal) where unencrypted wireless peripherals present a real compliance exposure.
- Scissors Switch Mechanism — Quiet, Low-Profile: Scissors switches provide a more tactile response than membrane rubber domes while staying quieter than mechanical switches. The 0.58 in (14.80 mm) keyboard height keeps wrist angles flat on standard desktops without requiring a wrist rest.
- Dedicated Copilot Hot Key: The Copilot key provides single-keystroke access to Microsoft Copilot on supported Windows 11 deployments. For organizations running Microsoft 365 Copilot licenses, this removes friction from the AI-assist workflow without requiring custom key remapping.
- 3-Zone Layout with Programmable Keys: The 3-zone layout groups function, navigation, and numeric input into visually distinct areas, reducing search time for users transitioning from different keyboard models. Programmable keys allow IT to standardize shortcuts across a fleet without per-user configuration.
- Adjustable Tilt — Ergonomic Positioning: The adjustable tilt lets each user set a typing angle that suits their desk height and seating position — a meaningful factor for reducing wrist fatigue in extended typing sessions.
- 65% Post-Consumer Recycled Material: If your organization tracks sustainability metrics for hardware procurement, the 4Y41R64505 qualifies with 65% post-consumer waste content — a verifiable spec for ESG reporting, not a marketing claim.
- Full-Size 104-Key Layout — No Compromises: The full-size form factor preserves the numeric keypad — essential for finance, data entry, and ERP-heavy roles where eliminating the numpad creates genuine workflow friction. No compact trade-offs here.
- Gray Finish — Professional Aesthetic: The neutral gray colorway integrates cleanly into standard office workstation setups and matches the majority of commercial monitor and desk configurations without the clutter of high-contrast colorways.
Integration and Compatibility
The 4Y41R64505 is designed for PC platforms running Windows. The Copilot hot key is functional on Windows 11 with Microsoft Copilot enabled. The USB Type-A unified receiver provides RF connectivity across any PC with a standard USB-A port. Bluetooth mode is compatible with PC systems supporting standard Bluetooth profiles — no proprietary driver stack required for basic operation. This keyboard does not require software for core functionality, though Lenovo device management software may unlock additional programmable key configuration options in managed fleet deployments.
Frequently Asked Questions
Q: What wireless options does the 4Y41R64505 support?
A: The 4Y41R64505 supports both Bluetooth and 2.40 GHz RF wireless. RF operation uses the included USB Type-A unified pairing receiver. Bluetooth allows connection without using a USB port.
Q: How long does the rechargeable battery last on the 4Y41R64505?
A: Lenovo rates the battery at up to three months of typical use per charge. Actual battery life will vary with usage intensity and wireless mode.
Q: What is the warranty on the 4Y41R64505?
A: The 4Y41R64505 carries a 3-year limited warranty. It is designated a Customer Replaceable Unit (CRU), meaning warranty service typically involves a replacement unit shipped to the end user rather than depot repair.
Q: Does the 4Y41R64505 work with Mac or Linux systems?
A: Lenovo specifies the 4Y41R64505 for PC platforms. Mac and Linux compatibility is not stated in the product documentation — confirm with your system configuration before deploying outside Windows environments.
Q: Is wireless data encrypted on the 4Y41R64505?
A: Yes. The 4Y41R64505 uses 128-bit AES encryption for wireless data transmission, covering both Bluetooth and RF connection modes.
Q: Does the Copilot key require any special setup?
A: The dedicated Copilot hot key is designed for Windows 11 environments with Microsoft Copilot enabled. Standard Microsoft 365 Copilot licensing and Windows 11 are required for full functionality.
The 4Y41R64505 is one of the more practical choices I've seen for large professional PC rollouts — specifically because of the three-month rechargeable battery. In a fleet of 50 or 100 keyboards, disposable-battery replacements add up fast in both cost and IT time. Switching to a keyboard that charges like a phone and only needs attention quarterly changes the maintenance calculus meaningfully.
Technical Highlights:
- Dual Wireless (Bluetooth + 2.40 GHz RF): Having both modes on a single unit gives you flexibility across different workstation configs — USB-A receiver for fixed desks, Bluetooth for systems where USB ports are already spoken for or where Bluetooth device management is centrally handled.
- 128-Bit AES Encryption: Hardware-level encryption on both wireless modes is the right spec for any environment where unencrypted peripheral traffic would fail a security audit — financial services, healthcare, government adjacent. This isn't a checkbox; it's a real differentiator versus budget wireless keyboards that skip encryption entirely.
- 65% Post-Consumer Recycled Content: If your procurement team tracks Scope 3 emissions or EPEAT-style sustainability metrics, this is a verifiable number you can document — not a vague
