Logitech WIRELESS KEYBOARD K350 Repair

The Wireless Keyboard K350 is an ergonomic, full-size wireless keyboard designed for comfortable long typing sessions, recognizable by its wave-shaped key layout and cushioned palm rest. It is built from durable ABS plastic with a coated finish and a spill-resistant design intended to withstand daily office use. Key features include an ergonomic wave contour, full numeric keypad, multimedia hotkeys, and a compact 2.4 GHz USB receiver for wireless connectivity. The K350 uses long-life battery design and simple plug-and-forget wireless pairing for reliability.

The Logitech WIRELESS KEYBOARD K350 includes Keyboard (M/N Y-R0053) and USB receiver (M/N C-U0007). Model labels are located as follows — Keyboard: 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.

• Form Factor: Full-size, wave ergonomic layout with integrated cushioned palm rest
• Switch Type: Rubber dome membrane (Logitech proprietary membrane key switches)
• Connectivity: 2.4 GHz wireless via USB nano receiver (plug-and-forget) — may be Unifying-compatible on some revisions
• Receiver Model(s): Varies by production run; typically a Logitech nano USB receiver (model information printed on the receiver housing; not all units are Unifying-receiver variants)
• Power: 2 × AA batteries (user-replaceable); rated for extended battery life (multi-year typical, varies with usage)
• Backlighting: None (no backlit keys)
• Hotkeys / Controls: Multimedia and hotkeys (volume, media playback, and shortcut keys); F-key functions vary by OS and driver support
• Materials: Durable ABS plastic housing with coated finish and spill-resistant key well; foam-cushioned palm rest
• Range: Typical wireless range up to ~10 meters (line-of-sight) depending on environment

Common repair-relevant faults include unresponsive keys (often caused by debris or degraded rubber domes) and connectivity/pairing failures. Diagnose by swapping batteries, testing the receiver in multiple USB ports, re-pairing or replacing the nano receiver, and using a key tester to isolate failed keys; opening the case allows inspection of the membrane and PCB for corrosion or physical damage.
