Check whether the mouse or entire computer is unresponsive
Try the keyboard: switch applications or open a menu using known keyboard shortcuts. If the keyboard also fails, the computer may be frozen rather than the mouse alone. Save work if possible before restarting. If the keyboard works, see whether the pointer moves on the desktop and whether left or right clicks work anywhere. A cursor that moves but will not click is a different symptom from a pointer that never changes position.
- Try a basic keyboard shortcut before disconnecting devices.
- Note whether movement, clicks or both are affected.
- Use a keyboard or accessibility alternative while diagnosing.
Inspect a wired USB connection safely
Make sure the USB cable is fully seated and undamaged. Try another appropriate port directly on the computer rather than through a loose hub. If it works in one port but not another, the port or hub deserves attention. Do not force a connector, bend pins or open a power adapter. Some office computers restrict external input devices through security software; follow local policy before changing equipment or installing drivers.
- Inspect for obvious cable damage without pulling the wire.
- Compare a direct computer port with a problematic hub.
- Try a second working mouse to isolate a USB issue.
Check wireless power and connection type
Turn the mouse on and check battery charge or replace approved batteries. A receiver-based device requires its compatible USB dongle; Bluetooth pairing uses the computer's Bluetooth radio and device discovery. These methods are not automatically interchangeable. A low battery can produce intermittent behavior before total failure. Move the mouse closer to its receiver and make sure it is not hidden behind metal or near high-interference equipment.
- Identify Bluetooth versus proprietary receiver before pairing.
- Check power, charging and sleep behavior.
- Follow the wireless troubleshooting guide if disconnects recur.
Review operating-system recognition and settings
In Windows, inspect Settings for Bluetooth devices or mouse options and check official device updates. On macOS, use System Settings for Mouse and Bluetooth. Menu names vary with release. If a new device was just installed, look for an operating-system permission prompt or an unsupported connection mode. Avoid uninstalling drivers without a recovery keyboard or other working input. Prefer official support guidance for the device's specific model.
- Check whether the device is recognized by the operating system.
- Review any recent setting, app or driver change.
- Do not install untrusted driver-fix applications.
Use comparative tests, not guesswork
A mouse may fail in one application while working in the rest of the system. Test another app and, if safe, another computer. If a second mouse works in the same port, that narrows the problem but does not conclusively identify a damaged component. When mouse movement reaches the browser, the all-in-one tool can show button, wheel and movement events. If the mouse is completely unusable, navigate this guide with a keyboard instead.
- Compare a second application and another port.
- Try the same mouse on another computer when possible.
- Record the most recent configuration change before the problem started.
Choose the least risky next action
After changing one thing, repeat a simple movement, a single click and a wheel scroll. If the mouse works again, keep the successful configuration and monitor intermittent failures. If a known-good mouse also fails, consider broader system troubleshooting. If only the original mouse fails across computers and connection checks, seek model-specific manufacturer support or warranty service. There is no website button that can automatically repair a physical switch or sensor.
- Retest movement, buttons and scrolling separately.
- Document the model, connection and steps already attempted.
- Consult manufacturer support for persistent or physically damaged devices.
