Wireless keyboards and mice have become very popular in homes and offices around the world. In fact, according to market research, over 60% of computer users now use wireless input devices for convenience and a cleaner workspace. But while these devices are generally reliable, problems can still happen. One common issue is when your wireless mouse works fine, but the keyboard doesn’t respond at all.
This can be confusing—especially since both devices often share the same USB receiver. Fortunately, in most cases, this problem can be solved without needing professional help. Whether it’s a simple battery issue, a connection problem, or something more technical like a driver conflict, this guide will walk you through all the possible reasons and show you how to fix each one step by step.
By the end of this article, you’ll have a clear understanding of why your wireless keyboard isn’t working and how to get it back up and running smoothly.
In this guide, we’ll delve into the most common causes, step-by-step troubleshooting methods, and tips to prevent future issues with wireless keyboards.

1. Battery Issues: The Most Overlooked Cause
Why It Happens:
Wireless keyboards rely on battery power to operate. Unlike a mouse that often gives obvious signs when the battery is low (e.g., lagging cursor, blinking light), keyboards might stop responding abruptly with little warning.
How to Fix:
- Check for signs of life: Look for any indicator LEDs on the keyboard. If there’s none, proceed with changing the batteries.
- Use fresh batteries: Even if your current batteries worked recently, they may no longer provide sufficient voltage. Replace both batteries (if AA/AAA) with new ones from a reputable brand.
- Recharge if applicable: If your keyboard is rechargeable, plug it in for at least 30 minutes before testing.
- Inspect for corrosion: Sometimes battery compartments develop corrosion. Clean it carefully using a cotton swab and isopropyl alcohol.
Pro Tip:
Keep a set of fresh batteries handy and develop a habit of replacing them every few months, especially if the keyboard is in heavy use.
2. Power Switch or Sleep Mode
Why It Happens:
Most wireless keyboards have a physical power switch to conserve energy. It may be inadvertently turned off or enter a sleep mode after prolonged inactivity.
How to Fix:
- Locate the power switch, usually on the back or side of the keyboard. Flip it to the “ON” position.
- Press any key firmly to wake the device from sleep. Some models need a key combination (like Ctrl+Alt) to exit sleep.
- Hold the power button on some models to reset or reinitialize the keyboard.
3. Connection Issues with the USB Receiver or Dongle
Why It Happens:
The USB receiver acts as the bridge between your wireless keyboard and your computer. If the connection is interrupted or partially established (allowing mouse but not keyboard input), it could be due to syncing errors.
How to Fix:
- Unplug the receiver and plug it back into a different USB port (preferably a USB 2.0 port if available).
- Avoid using USB hubs or extenders, as they can cause connectivity issues or reduce power delivery.
- Re-sync the keyboard: Use the manufacturer’s software (e.g., Logitech Options, Microsoft Mouse and Keyboard Center) to manually pair the keyboard again.
- Test on another computer: If the keyboard still doesn’t work, the issue likely lies with the keyboard itself.
Bluetooth Keyboards:
If using Bluetooth, ensure:
- The device is paired properly and shows as “Connected” in Bluetooth settings.
- Remove and re-pair the device if necessary.
- Check for interference or out-of-range issues.
4. Driver Conflicts or Outdated Software
Why It Happens:
Device drivers help the operating system communicate with peripherals. A corrupted or outdated driver can prevent your keyboard from working even if the mouse is unaffected.
How to Fix:
On Windows:
- Open Device Manager (press Win + X > Device Manager).
- Expand the “Keyboards” section.
- Right-click your keyboard and select Update driver > “Search automatically for updated drivers.”
- If the update fails or doesn’t help, right-click and choose Uninstall device, then restart your PC to auto-reinstall.
On macOS:
- Open System Settings > Bluetooth or Keyboard.
- Remove and re-pair the keyboard.
- Use Software Update to ensure your macOS is current.
Tip:
Some manufacturers (like Logitech, HP, or Dell) offer custom drivers—download these from their official websites for best compatibility.
5. Faulty or Incompatible USB Port
Why It Happens:
The USB port that powers the receiver may have physical damage or be temporarily disabled due to power-saving settings or system glitches.
How to Fix:
- Try another port, ideally directly on the motherboard (rear I/O) instead of front panel ports.
- Disable USB selective suspend in Windows Power Options to prevent ports from turning off.
- Avoid using high-speed USB 3.0 ports with older peripherals if compatibility issues arise.
6. Interference from Other Wireless Devices
Why It Happens:
Many wireless keyboards and mice operate in the 2.4 GHz frequency band, which is shared with Wi-Fi routers, cordless phones, Bluetooth devices, and even microwave ovens.
How to Fix:
- Move the receiver closer to the keyboard using a USB extender cable.
- Relocate Wi-Fi routers or other RF devices farther from your work area.
- Limit nearby Bluetooth activity if you’re using a Bluetooth keyboard.
7. Keyboard Hardware Failure
Why It Happens:
Over time, keyboards can suffer from hardware degradation, faulty internal wiring, or damaged sensors, especially if they’ve been dropped, exposed to spills, or stored improperly.
How to Fix:
- Test the keyboard on another computer. If it fails to work across multiple systems, the issue is likely internal.
- Check for warranty coverage. If the product is still under warranty, contact the manufacturer for repair or replacement.
- Inspect physically for stuck keys, visible damage, or broken switches.
8. BIOS/UEFI-Level Issues (Advanced)
Why It Happens:
Sometimes, USB keyboards may not work during startup due to settings in the BIOS/UEFI firmware or legacy USB support being disabled.
How to Fix:
- Reboot your computer and enter the BIOS/UEFI setup (usually by pressing Del, Esc, or F2 during boot).
- Check for a setting like “USB Legacy Support” and ensure it is enabled.
- Save changes and exit.
Preventive Measures and Long-Term Tips
- Regularly update drivers and peripheral firmware via official tools.
- Avoid spills and dust—use keyboard covers if needed.
- Use a surge protector or UPS to prevent electrical damage during power surges.
- Maintain proper distance between the receiver and keyboard (ideally under 1.5 meters for 2.4GHz models).
When to Replace Your Wireless Keyboard
If your keyboard:
- Doesn’t respond even after battery replacement and re-pairing,
- Is not detected by multiple systems,
- Has visible physical damage, or
- Is over 5 years old and unsupported,
…it may be time to invest in a new model. Consider well-reviewed keyboards from brands like Logitech, Microsoft, Corsair, or Keychron.
Final Thoughts
A non-working wireless keyboard with a functional mouse is frustrating but not uncommon. Thankfully, most causes—from drained batteries to driver glitches—can be resolved with careful troubleshooting. By systematically checking each possible factor, you can restore your keyboard’s functionality and avoid future interruptions.
If problems persist, professional help or replacement might be necessary—but in most cases, users can resolve the issue on their own.
