Logitech ADVANCED Combo Wireless Keyboard and Mouse Repair

The ADVANCED Combo Wireless Keyboard and Mouse (Logitech MK540 Advanced series) is a full‑size wireless keyboard and contoured mouse combo designed for everyday productivity. It pairs both devices to a single Logitech Unifying™ USB receiver for a reliable 2.4 GHz wireless connection up to 10 meters.

Plug-and-play operation with long battery life and a focus on comfort are key features.

The Logitech ADVANCED Combo Wireless Keyboard and Mouse includes Keyboard (M/N Y-R0012), Mouse (M/N MR0085) and USB receiver (M/N C-U0010). Model labels are located as follows — Keyboard: on the underside product label; Mouse: on the underside product label; USB Receiver: printed on the flat face or side of the receiver housing near the USB plug. Each component carries its own model (M/N) and serial (S/N) identifiers.

Most common faults are dead/weak batteries, wireless pairing/receiver issues, and sticky or non‑responsive keys. Diagnose by replacing batteries, re‑pairing the Unifying receiver (or testing the receiver on another USB port/PC), and visually inspecting/removing keycaps to check for debris or damaged key mechanisms. If the receiver is lost or the mouse/keyboard hardware is physically damaged, component-level repair usually requires opening the housing to inspect battery contacts and the PCB.
