Lenovo Essential Wireless Keyboard & Mouse Combo Gen 2 4X31R64453
The Lenovo Essential Wireless Keyboard & Mouse Combo Gen 2 (4X31R64453) is a slim, quiet desktop set for offices, home workspaces and shared desks. One USB-A receiver connects both devices over 2.4 GHz, and the keyboard adds a dedicated Copilot key, a spill-resistant design and up to 15 months of battery life.
Key features
- One receiver, two devices: a single Lenovo USB-A receiver links the keyboard and mouse over a reliable 2.4 GHz connection, with AES-128 encryption on the keyboard.
- Copilot key: opens Copilot in Windows with one press. If Copilot isn't available or enabled on the PC, the key opens Windows Search instead.
- Comfortable everyday typing: a low-profile 2.5-zone layout, adjustable tilt leg, spill-resistant design and keys rated for up to 10 million clicks.
- Long battery life: up to 15 months for the keyboard and up to 18 months for the mouse (varies with usage), so battery changes are rare.
- Ambidextrous mouse: a full-size 1600 DPI optical mouse that suits left- or right-handed users. Both devices use 65% post-consumer recycled plastic.
