Ensure your device has an available USB port and meets the minimum system specifications for a smooth user experience.
Setting Up Your K400 Plus
Effortlessly connect and begin using your new keyboard with a simple setup process, involving battery installation and the USB receiver for immediate functionality.
Installing the Batteries
To begin, locate the battery compartment on the underside of the Logitech K400 Plus keyboard. Gently slide the battery compartment cover open, typically in the direction indicated by an arrow or release button.
Insert two AA batteries into the compartment, ensuring correct polarity. The positive (+) and negative (-) ends are usually marked within the compartment; match the battery ends accordingly. Incorrect battery installation will prevent the keyboard from powering on.
Once the batteries are securely in place, carefully slide the battery compartment cover back on until it clicks into a locked position. A secure closure is vital for maintaining a stable power connection.
After installing the batteries, the keyboard should automatically power on. If it doesn’t, double-check the battery polarity and ensure the batteries are fresh and fully charged for optimal performance.
Connecting the USB Receiver ౼ Plug and Play
The Logitech K400 Plus utilizes a small USB receiver for a wireless connection. Locate the USB receiver, often stored within the battery compartment or securely attached to the keyboard;

Troubleshooting Common Issues
This section addresses frequent problems with the K400 Plus, including unresponsive keys, touchpad malfunctions, and connection difficulties, offering practical solutions for a smooth experience.
Keyboard Not Responding ౼ Solutions
If your Logitech K400 Plus keyboard isn’t responding, several troubleshooting steps can resolve the issue. First, ensure the batteries are fresh and correctly installed, as low power is a common cause. Try replacing them with a new set.
Next, verify the USB receiver is securely plugged into a working USB port on your computer. Experiment with different USB ports, as some may provide insufficient power. If using a USB hub, connect the receiver directly to the computer;
Occasionally, the receiver may lose connection; try unplugging and re-plugging it. If problems persist, attempt re-pairing the keyboard with the receiver (refer to the ‘Initial Pairing’ section). Ensure no physical obstructions interfere with the wireless signal. Finally, restart your computer – a simple reboot often resolves temporary software glitches.
Touchpad Malfunctions ー Fixing Sensitivity
Experiencing issues with your K400 Plus touchpad? Adjusting the sensitivity is often the first step to resolving erratic cursor movement or unresponsiveness. Logitech Options software (see ‘Logitech Options Software’ section) allows for precise control over touchpad settings, including cursor speed, scrolling speed, and gesture customization.
Within the software, experiment with different sensitivity levels to find a setting that suits your preference and usage style. If the touchpad feels too sensitive, reducing the sensitivity will minimize accidental cursor jumps. Conversely, increasing it enhances responsiveness.
Ensure the touchpad surface is clean and dry, as dirt or moisture can interfere with its operation. Restarting your computer can also resolve temporary software conflicts affecting touchpad performance. If issues continue, check for available firmware updates via Logitech Options.
Connection Problems ౼ USB Receiver Issues
If your K400 Plus isn’t connecting, the USB receiver is the prime suspect. First, ensure the receiver is firmly plugged into a working USB port on your computer – try a different port to rule out a faulty connection. Avoid USB hubs initially, connecting directly to the computer instead.
If the keyboard still doesn’t connect, attempt re-pairing. Press the connect button on both the keyboard and the receiver (refer to ‘Initial Pairing and Troubleshooting’). Ensure no other wireless devices are causing interference – move away from other Bluetooth devices or wireless routers.
A failing USB receiver may require replacement. Contact Logitech support for assistance or consider purchasing a replacement receiver. Check Logitech’s website for compatible receivers and ensure your operating system is fully updated.
Maintenance and Care
Regular cleaning and proper storage will extend the life of your K400 Plus. Keep the keyboard and touchpad free from dust and debris for optimal performance.
Replace batteries promptly to avoid interruptions and store the keyboard in a cool, dry place when not in use.
Cleaning the Keyboard and Touchpad
Maintaining a clean K400 Plus is crucial for optimal performance and longevity. Before cleaning, always disconnect the USB receiver to prevent accidental input.
For the keyboard, gently turn it upside down and tap to dislodge loose particles. Use a can of compressed air to remove dust and debris from between the keys, holding the can upright to avoid liquid propellant.
Dampen a soft, lint-free cloth with water or a mild, non-abrasive cleaning solution. Avoid harsh chemicals or solvents, as they can damage the keycaps. Wipe the keycaps and the keyboard surface gently.
To clean the touchpad, use the same dampened cloth. Avoid excessive moisture, and ensure the touchpad is completely dry before use. Do not spray any liquid directly onto the keyboard or touchpad. A slightly damp cloth is sufficient for effective cleaning.
Regular cleaning prevents buildup and ensures smooth operation of both the keyboard and the integrated touchpad.
Battery Life and Replacement
The Logitech K400 Plus operates on two AA batteries, offering an impressively long battery life. You can expect up to 18 months of usage under typical conditions, though actual battery life varies with use.
When the batteries are low, a red LED indicator will illuminate on the keyboard. This serves as a clear warning to replace them promptly to avoid interruption.
To replace the batteries, slide open the battery compartment cover located on the underside of the keyboard. Remove the old batteries and insert two new AA batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
Logitech recommends using alkaline batteries for optimal performance. Avoid mixing old and new batteries, or different types of batteries. Always dispose of used batteries responsibly, following local regulations.
Replacing the batteries is a simple process, ensuring continued seamless operation of your K400 Plus.
Storing Your K400 Plus
When not in use, proper storage of your Logitech K400 Plus will help maintain its functionality and extend its lifespan. Choose a clean, dry location, away from direct sunlight and extreme temperatures.
Avoid storing the keyboard in areas with high humidity, as this can potentially damage the internal components. A temperature-controlled environment is ideal.
It’s recommended to remove the batteries if you plan to store the keyboard for an extended period (more than a few months). This prevents potential battery leakage and corrosion.
When storing, protect the touchpad from scratches and dust. Consider placing the keyboard in a protective sleeve or wrapping it in a soft cloth.
Avoid placing heavy objects on top of the keyboard during storage, as this could damage the keys or touchpad. Proper storage ensures your K400 Plus remains ready for use.
