🔋 1. Check or Replace the Batteries
The most common reason a wireless mouse stops working is dead or weak batteries.
✅ Solution:
- Replace with fresh batteries — even if it was working a few minutes ago.
- If it uses a rechargeable battery, connect it to charge and wait a few minutes.
- Make sure the batteries are inserted correctly (check polarity symbols inside the battery compartment).
🔌 2. Check the USB Receiver (Dongle)
Most wireless mice (unless Bluetooth) use a USB receiver. If the dongle is loose, missing, or plugged into a faulty port, the mouse won’t work.
✅ Solution:
- Unplug the receiver and plug it into a different USB port.
- Avoid USB hubs or extension cables — use a direct USB port on your computer.
- Inspect the receiver for damage or dust.
🔄 3. Reconnect or Re-Pair the Mouse
Sometimes the mouse simply loses connection with the receiver or computer.
✅ Solution:
- Turn the mouse off and back on.
- Press the connect/pair button (if available) on the mouse and/or receiver.
- Remove and reinsert the USB receiver while the mouse is turned on.
🧩 4. Try the Mouse on Another Device
To rule out problems with your computer, test the mouse on a different laptop or PC.
✅ If it works on another computer:
- The issue is likely driver-related or USB-related on your original device.
✅ If it doesn’t work:
- It may be a hardware issue with the mouse itself.
🧰 5. Check for Driver Issues (Windows/Mac)
Corrupt or outdated drivers can stop your mouse from working correctly.
✅ Windows:
- Open Device Manager
- Look under Mice and other pointing devices
- Right-click your mouse ➝ Update driver or Uninstall device and restart your computer
✅ macOS:
- Go to System Settings ➝ Bluetooth if using a Bluetooth mouse
- Remove and re-pair the mouse if necessary
🔧 6. Check for Interference or Range
Wireless mice can be affected by signal interference or long distances from the receiver.
✅ Solution:
- Keep the mouse within 1–2 feet of the receiver
- Remove nearby wireless routers, cordless phones, or metal objects
- Don’t block the receiver with other USB devices or metal cases
⚠️ 7. Physical Damage or Defect
If the mouse was dropped, exposed to moisture, or simply old, it may be physically damaged.
✅ Solution:
- Look for broken switches, loose scroll wheel, or battery corrosion
- If under warranty, contact the manufacturer for a replacement
