Mouse Issues
If your mouse is unresponsive, lagging, or disconnects intermittently, it’s often caused by power, driver, or signal problems. Use the following steps to identify and fix the issue.
💡 Applies to: Windows 10, Windows 11, USB, wireless, and Bluetooth mice.
🔌 Step 1: Check Connections
- Unplug and reconnect the mouse to a working **USB port**.
- Try a different port or another computer to confirm it’s not a hardware failure.
- For wireless mice, **replace or recharge the batteries** and make sure the power switch is on.
- If it’s a **Bluetooth mouse**, verify it’s connected under Settings → Bluetooth & devices.
🧰 Step 2: Check Receiver or Wireless Dongle
- Unplug the receiver, wait 10 seconds, then plug it back in.
- Try moving the receiver to a **different port**, preferably on the front of your PC or a short extension cable.
- Avoid connecting through a USB hub — plug directly into the computer instead.
⚙️ Step 3: Update or Reinstall Mouse Drivers
- Press Win + X → select Device Manager.
- Expand Mice and other pointing devices.
- Right-click your mouse → Update driver → Search automatically.
- If issues continue, right-click again → Uninstall device, then restart the PC to reinstall automatically.
🧪 Step 4: Disable USB Power Saving
- Open **Device Manager** and expand Universal Serial Bus controllers.
- Right-click each **USB Root Hub** → select **Properties** → open the **Power Management** tab.
- Uncheck **Allow the computer to turn off this device to save power**.
⚡ Step 5: Check for Lag or Interference
- Ensure the receiver isn’t too far from the mouse — ideally within 2–3 feet.
- Keep the receiver away from **routers, cell phones, or metal surfaces** that may cause interference.
- Use a **mouse pad** — glass or reflective surfaces can confuse the sensor.
🧹 Step 6: Clean the Mouse Sensor
- Power off or disconnect the mouse.
- Clean the sensor lens with a **soft cloth or cotton swab**.
- Remove any debris or dust around the scroll wheel or buttons.
🔋 Step 7: Bluetooth & Wireless Fixes
- Re-pair the device in Settings → Bluetooth & devices.
- Make sure Windows is fully up to date — Settings → Windows Update.
- Replace batteries or charge the device fully before testing again.
✅ After following these steps, most mouse connection or lag issues are resolved.
If not, try another mouse — if that works, your original mouse may be failing.
