If your wireless keyboard or mouse stopped responding, you can usually get it working again with a few simple checks. This guide walks you through the most common causes and step‑by‑step solutions so you can avoid costly replacements. For a related guide, see Windows Update Stuck or Failing? How to Fix It.

Common Causes
- Low or dead batteries – the most frequent culprit.
- Lost connection – the USB receiver may be unplugged, lost signal, or the device is out of range.
- Interference – other devices, thick walls, or busy Wi‑Fi channels can disrupt Bluetooth.
- Power‑saving settings – Windows (or macOS) may turn off peripherals after a period of inactivity.
- Driver or firmware glitches – outdated software can cause sporadic behavior.
- Hardware fault – a broken scroll wheel, stuck key, or faulty contact inside the device.
Quick Fixes to Try First
- Check the batteries.
- Open the battery compartment.
- If the indicator lights are dim or absent, replace the batteries with fresh ones (or recharge a rechargeable unit).
- Make sure the USB receiver is securely attached.
- Plug the receiver into a functioning USB port (preferably a rear‑panel port on a desktop).
- Check that the connector is fully inserted.
- If your receiver has a on/off switch, ensure it is set to the “on” position.
- Restart the computer and the peripheral.
- Turn the keyboard/mouse off (if they have a power switch) and back on.
- Restart Windows or macOS.
- Reset the connection.
- Unpair the device (Settings > Devices > Bluetooth & other devices > Remove device).
- Power cycle the receiver (unplug it for 10 seconds, then plug it back in).
- Re‑pair using the manufacturer’s pairing button (usually on the underside of the keyboard or mouse).
- Disable power‑saving for peripherals.
- Windows: Control Panel > Hardware and Sound > Power Options > Choose what the power buttons do > “Allow fast startup” (uncheck if needed) and ensure “USB selective suspend” is disabled.
- macOS: System Preferences > Energy Saver > tick “Put accessories to sleep when not in use” to turn it off.
Specific Steps by Connection Type
USB Receiver (Dongle) Issues
- Try a different USB port. Use a port that you know works (e.g., a mouse port on a docking station).
- Test the receiver on another computer. If it works there, the original PC may have a faulty port or driver.
- Check for physical damage. A bent pin or cracked housing can prevent contact.
- Update the receiver driver.
- Right‑click the Start button > Device Manager > Batteries > “Battery driver” (if present) or “HID-compliant consumer devices”.
- Right‑click > Update driver > Search automatically.
Bluetooth Connection Issues
- Place the peripheral within 5–10 cm of the computer. Thick walls or metal objects can weaken the signal.
- Unpair and re‑pair.
- Windows: Settings > Devices > Bluetooth & other devices > Remove device > Add device > Bluetooth > select your keyboard/mouse > pair.
- macOS: System Preferences > Bluetooth > forget the device > turn it on and click Connect.
- Ensure the computer’s Bluetooth is on. Some laptops have a function key to toggle Bluetooth; verify the icon appears in the notification area.
- Check for interference. Move away from Wi‑Fi routers, microwaves, or other Bluetooth devices for a minute, then try again.
- Update Bluetooth drivers. Follow the same steps as the receiver driver update above.
Battery‑Related Solutions
- Use rechargeable cells correctly. Some wireless keyboards/mice have a low‑power indicator. If the light flashes, charge them for at least 2 hours before reuse.
- Check for corrosion. If the battery contacts are dirty, clean them with a dry cotton swab. Avoid using liquids.
- Switch to a different battery type. Alkaline batteries often outlast NiMH in low‑draw devices.
- Inspect the battery compartment. A cracked compartment can cause intermittent power loss.
When Basic Steps Fail
- Test the device on another computer. If it works, the problem is with the original PC’s settings or hardware.
- Update or roll back the OS. Windows Update or macOS Software Update can resolve driver conflicts. If a recent update broke the peripherals, consider rolling back.
- Check for conflicting software. Some security suites or remote‑desktop tools can block low‑latency input devices. Temporarily disable them and test.
- Inspect for physical damage. Stiff keys, a non‑responsive scroll wheel, or a loose antenna can signal a hardware fault. If you see obvious damage, consider replacement.
- Try a different receiver or dongle. Many manufacturers ship extra USB receivers; swapping them can isolate a faulty unit.
- Reinstall the device driver.
- Device Manager > Batteries > right‑click > Uninstall device > Restart to let Windows reinstall.
Practical Alternatives
- Switch to a wired keyboard/mouse temporarily; this confirms the issue is wireless‑related.
- Purchase a **2.4 GHz dual‑mode receiver** that can work with both keyboard and mouse on a single dongle (some brands allow adding extra devices).
- Consider Bluetooth LE peripherals if your current devices use older Bluetooth standards and you want better battery life.
- Use USB-C adapters for thin laptops where the full‑size USB port is unavailable.
Key Takeaways
- Start with batteries and the USB receiver; those are the fastest fixes.
- Reset the connection by removing the device and re‑pairing it; this often restores lost signal.
- Power‑saving and driver issues are common; updating Windows/macOS and disabling “suspend USB” usually resolves them.
- If the hardware itself appears damaged, replace the peripheral rather than spending time troubleshooting.
When to Seek Further Help
If none of the steps above restore functionality, the problem likely lies in the device’s internal electronics or a deeper system issue. Contact the manufacturer’s support line with the serial number, or take the peripheral to a professional repair service.
Keeping a spare set of rechargeable batteries and a backup USB receiver can save downtime when wireless peripherals fail.
