1. Basic Checks
Wired Mouse:
Ensure the USB cable is securely plugged into the port.
Try a different USB port (avoid USB hubs).

Wireless Mouse:
Replace or recharge batteries.
Reconnect the receiver (unplug/replug or use the pairing button).

Ensure no physical obstructions block the sensor (bottom of the mouse).

2. Inspect for Physical Damage
Check the cable (wired mice) for fraying, bends, or cuts.
Examine buttons for stuck or unresponsive clicks (press repeatedly to test).

Test the scroll wheel: Spin it to see if it’s smooth or grinding.

3. Clean the Mouse

Buttons/Sensor:
Use compressed air to blow dust/debris from gaps.
Wipe the sensor (bottom) with a microfiber cloth.
Sticky Buttons:
Dampen a cotton swab with isopropyl alcohol and clean around buttons.
4. Test on Another Device.jpeg)

Connect the mouse to another computer/laptop to confirm if the issue persists.
If it works elsewhere, the problem is likely with your original device’s hardware/software.
5. Check Internal Components (Advanced)
Wired Mouse:

Open the mouse casing (voids warranty!) and check for loose wires or disconnected circuits.
Wireless Mouse:

Inspect battery contacts for corrosion (clean with alcohol if needed).

6. Test the Sensor.jpeg)

Use the mouse on different surfaces (e.g., mousepad, paper, desk).
If the cursor jumps or freezes, the sensor may be faulty.
7. Check Button Switches.jpeg)

Faulty microswitches under buttons cause unresponsive clicks.
Replace switches (requires soldering skills) or buy a new mouse.
8. Bluetooth Mouse Specific.jpeg)

Re-pair the mouse:
Turn off Bluetooth > Remove the mouse from paired devices > Re-pair.
9. Replace the Mouse.jpeg)

If all steps fail, the mouse has a hardware failure (e.g., dead sensor, broken switches).
For branded mice (Logitech, Razer), contact customer support for warranty claims.
Common Hardware Failure Signs
Intermittent clicks.
Cursor movement issues (jumping, lagging).
Scroll wheel not registering input.
