Mouse buttons stop responding when the battery is low

Your wireless mouse may still move the pointer, but clicks start getting missed or a button stops responding. A weak battery can interrupt the wireless connection, though a worn switch, loose receiver, or app setting can cause similar symptoms.

Test the buttons before and after restoring power. The Mouse Test checks button presses, the scroll wheel, double-clicks, and polling rate. It can show whether clicks reach the browser, but it cannot measure the battery itself.

Test the mouse buttons

1. Open the Mouse Test on the computer where the problem occurs.
2. Click each mouse button several times, including the wheel click and any side buttons. Watch whether each press registers.
3. Scroll a few times and move the pointer while you click. Note whether the pointer also pauses or jumps when a click fails.
4. Replace the batteries or charge the mouse, then repeat the same clicks. For a fair comparison, keep the mouse, receiver, and test page in the same positions.

Try ordinary single clicks first. Avoid rapid clicking during the comparison, because an overly fast sequence can make it harder to tell a missed press from a double-click timing issue.

What the result means

The buttons work after you replace or charge the battery

Low power was likely affecting the mouse or its wireless link. If the problem returns soon with a fresh battery or full charge, check whether the battery is seated properly and whether the mouse is charging as expected. A battery indicator in your operating system is only available for some mouse models.

Pointer movement and clicks both pause

This points more toward an interrupted wireless connection or weak power than toward one broken button. A low battery can reduce reliable operation, but distance, radio interference, or a receiver connection can also cause pauses. Try the connection checks below.

One button still fails, but the others work

If the same button fails after fresh batteries or a full charge, the button switch may be worn or damaged. Test it in another application and, if possible, on another computer. A browser test can show that a click did not arrive, but it cannot tell whether the switch or the mouse's internal electronics caused the failure.

Every button registers in the test

The mouse is sending clicks to the browser at that moment. The problem may be limited to one game or app, or it may happen only intermittently. Check the app's button assignments and test again while the problem is occurring.

How to fix it

1. Replace or recharge the battery. For a mouse that uses replaceable batteries, install a fresh set of the correct type and check the polarity marks. For a rechargeable mouse, charge it using the method recommended by its maker. A short charge may help confirm the cause, but some models cannot be used while charging.
2. Check the battery contacts and power switch. Turn the mouse off before opening its battery compartment. Make sure the battery sits firmly against the contacts and that the power switch is fully on. Do not bend or scrape the contacts if they look damaged.
3. Reconnect the receiver or Bluetooth connection. If the mouse uses a USB receiver, unplug it and reconnect it directly to the computer rather than through a hub. If it uses Bluetooth, turn the mouse off and on, then reconnect it through your computer's Bluetooth settings.
4. Move the receiver closer. Put the receiver in a nearby USB port with a clear path to the mouse. Keep it away from a crowded USB hub, wireless router, or other devices that may interfere. Test at close range before moving back to your usual desk position.
5. Check whether the computer reports a charge level. Some wireless mice send battery information, but many do not. In Windows 11, look under Settings › Bluetooth & devices › Devices. On a Mac, open System Settings › Bluetooth. If no charge level appears, that does not prove the battery is healthy or faulty.
6. Try the mouse on another computer. Test its buttons there with a fresh battery or full charge. If the same button fails on both computers, the fault is more likely in the mouse. If it works elsewhere, check the original computer's mouse settings, Bluetooth connection, and any app-specific button assignments.

When the mouse may be faulty

If the same button keeps missing presses after you restore power and test on another computer, the mouse may have a worn switch or a damaged internal connection. A click that works only when pressed very hard, or only when pressed at an angle, is another sign of a physical problem. If the mouse is under warranty, contact the seller or manufacturer before opening it. For an inexpensive mouse, replacement may cost less than repair.

What the browser test can and cannot tell you

The Mouse Test records the button events the browser receives. It can help you compare the same mouse before and after charging, but it does not read battery capacity, inspect the radio signal, or diagnose the internal switch. A result can also vary if the mouse disconnects briefly during the test.

For a useful comparison, test in the same browser and on the same computer, then repeat a short set of clicks after changing one thing at a time. If the mouse works normally in the test but fails only in one app, focus on that app's settings rather than replacing the mouse.
