Mouse problem

Try these steps in order on the Asus laptop:

1. Check power on the mouse.
   • Make sure the mouse battery is fresh and installed correctly.
   • If the mouse has a light or pairing indicator, confirm it turns on.
2. If the M185 uses a USB wireless receiver:
   • Unplug the receiver.
   • Wait about 10 seconds.
   • Plug it back into a different USB port on the laptop.
   • If a USB hub is being used, remove it and connect the receiver directly to the laptop.
3. Check the mouse hardware.
   • Make sure there is no dirt blocking the sensor.
   • Check that the mouse and receiver are not physically damaged.
4. Test the mouse on another PC.
   • If it does not work there either, the mouse may need to be replaced.
   • Some devices need the correct driver installed when testing on another PC.
5. Update drivers through Windows Update.
   • In the taskbar search box, type check for updates.
   • Select Check for updates.
   • Under Windows Update, select Check for updates again.
   • Install any available updates.
6. If needed, update the device driver manually.
   • In the taskbar search box, type device manager.
   • Open Device Manager.
   • Find the mouse or related hardware category.
   • Double-click the device name.
   • Open the Driver tab.
   • Select Update Driver and follow the prompts.

If the mouse is actually a Bluetooth model, also check Bluetooth pairing:

• Press and hold the pairing button on the mouse for 5–7 seconds until the light blinks.
• On the laptop, go to Start > Settings > Devices > Bluetooth & other devices.
• Make sure Bluetooth is on.
• Select Add Bluetooth or other device > Bluetooth.
• Choose the mouse from the list and finish pairing.

If Bluetooth pairing still fails:

• Turn airplane mode on for 10–15 seconds, then turn it off.
• Turn off other Bluetooth devices temporarily.
• Remove the mouse from the Bluetooth device list and pair it again.
• If the pairing light flashes three times and turns off, the mouse is already paired to another PC nearby. Remove it from that PC first, then pair it again with the Asus laptop.
