Mouse not working

"Why is my mouse not working?" has at least five different answers, each with a different cause. Working through generic advice wastes time, so start by matching your symptom below. Where a step can be checked here rather than guessed at, it links to the test.

The symptoms people describe vary more than the faults do: a mouse not responding at all, a cursor not working while the buttons still register, a mouse lagging or stuttering, a cursor that has disappeared, a mouse that is not working properly rather than not at all, or one that suddenly stopped working after months of being fine. A faulty mouse and a mouse that no longer works are the same troubleshooting job: find the symptom, then the cause. Troubleshooting blind wastes time, so match your symptom first.

First: is it the mouse, or the computer?

Two checks separate a hardware fault from a software one, and they take under a minute.

• Plug the mouse into a different computer. If it misbehaves there too, the mouse is at fault and nothing you change in Windows will fix it.
• Plug a different mouse into this computer. If that one works, the problem is the mouse, not the machine.

If the cursor moves at all, run the mouse tester — it shows which buttons register and draws your cursor path, which usually identifies the fault immediately.

Nothing happens at all — no cursor, no lights

• Change the USB port, and use one directly on the computer rather than a hub or monitor. Front-panel ports on desktops are a common weak point.
• Check the cable where it enters the mouse. Bend it gently while watching the sensor light. Flickering means a broken conductor inside, and the mouse needs replacing.
• Wireless: replace the battery first before anything else. A dying battery causes far more "dead mouse" reports than any driver problem. Then reseat the USB receiver, and confirm any power switch underneath is on.
• Bluetooth: remove the pairing and pair again. Bluetooth mice routinely need re-pairing after a Windows update or a long sleep.

The cursor lags, freezes, jumps or moves on its own

A cursor that lags, stutters, jumps or drifts across the screen by itself is a tracking fault, and the surface is the first suspect. Optical sensors fail on glass and on high-gloss or strongly patterned desks; put a mousepad or a sheet of paper underneath and see if it settles. Then check the sensor window underneath for dust or a hair — a single fibre across it causes exactly this. On a laptop, a cursor moving on its own can also be your palm resting on the touchpad.

For wireless mice, lag and stuttering are usually interference or distance. Move the receiver to a front USB port or use a short extension so it sits on the desk rather than behind the machine, and keep it away from USB 3 ports and hubs, which are a well-known source of 2.4 GHz interference.

The tracking test draws your cursor path as a line: smooth means the sensor is reporting cleanly, while gaps and spikes show it dropping out. If the line is ragged, check the report rate too — a mouse that should report at 1000 Hz but measures far lower, or reports unevenly, points at the cable, the port or wireless interference rather than the sensor.

The cursor has disappeared

A pointer that has vanished while the mouse still works is usually hidden rather than broken, and each of these takes seconds to rule out.

• Move the mouse off every edge of the screen. If a second monitor or a TV was ever connected, the pointer may be sitting on a display you cannot see.
• Make Windows show you where it is. In Windows 11, open Settings → Bluetooth & devices → Mouse → Additional mouse settings, and on the Pointer Options tab tick "Show location of pointer when I press the CTRL key". Pressing Ctrl then circles the pointer wherever it is.
• It disappears only while you type because "Hide pointer while typing" is ticked on that same tab. It comes back the moment the mouse moves.
• On a laptop, check the touchpad key. If the touchpad is switched off and no mouse is connected, nothing is left to move the pointer.

A pointer missing inside a single game or app is being hidden by that program, and the setting is in its own options. If it is missing everywhere and none of these bring it back, restart the computer before trying anything else.

One button stopped working

Test each button first. If a button registers nothing at all, the switch has failed and needs replacing — that is a hardware repair, not a settings problem.

Before concluding that, rule out two things. Check that the buttons have not been remapped in the manufacturer's software, which is easy to do by accident and survives reboots. And for a mouse right click not working, or a left button that opens menus, check that the primary and secondary buttons have not been swapped: in Windows 11 that is Settings → Bluetooth & devices → Mouse → Primary mouse button.

A left click that keeps getting stuck, or a drag that drops what you are holding halfway, is usually the same wear that causes double-clicking: a worn switch briefly loses contact while it is held down. Rule out one setting first. ClickLock latches the button after a short press-and-hold, which feels exactly like a stuck click; it is on the Buttons tab of Additional mouse settings.

If the side buttons do nothing, that may be normal rather than broken. Firefox does not deliver side-button events to web pages at all, so they will read as untested here even on a working mouse, and many mice simply do not have them.

The mouse double-clicks on its own

A single click registering twice is the classic sign of a worn switch. The metal contact inside bounces as it closes, and once wear makes that bounce outlast the firmware's debounce window, the computer sees two presses.

You can confirm it rather than guess: the double-click test shows the exact interval in milliseconds between two presses. Anything under about 40 ms is faster than a finger can physically move, so the switch produced it, not you. The click speed test checks the same thing across a longer run and tells you how many presses were suspect.

There is no software fix. Some manufacturers' utilities let you raise the debounce time, which masks the symptom for a while at the cost of a little latency. The real remedies are a warranty claim, replacing the switch, or replacing the mouse.

The scroll wheel is erratic

A scroll wheel that jumps up and down — scrolling back a line as you roll forward — or does nothing now and then is usually a dirty or worn wheel encoder. Compressed air around the wheel sometimes clears it. If the wheel also feels gritty or has lost its distinct steps, the encoder is worn and the fix is hardware. The scroll test confirms which directions still register, including tilt.

If every notch scrolls the wrong way, that is a setting rather than a fault: current versions of Windows 11 have a Scrolling direction option under Settings → Bluetooth & devices → Mouse, and the mouse's own software can reverse it too.

Mouse not working on laptop

"Why is my mouse not working on my laptop?" usually has one of two answers. If it is an external mouse, the rest of this guide applies unchanged — a laptop mouse not working is diagnosed exactly like a desktop one, including the idle power-saving fix further down. If it is the built-in touchpad that stopped:

• Check the disable shortcut. Most laptops have a function key that turns the touchpad off, and it is easy to hit accidentally. Look for a small touchpad icon on the F-keys.
• Some laptops disable the touchpad automatically when a USB mouse is connected. Unplug the mouse and see if it returns.
• Check it is enabled in Settings → Bluetooth & devices → Touchpad.

Note that a touchpad has no middle or side buttons, so those will always read as untested in any mouse test, including this one. That is expected rather than a fault.

It cuts out at random while you are using it

A mouse that is plugged in but not working only some of the time — dropping out mid-sentence, freezing for a second, then coming back — is a different fault from one that dies when idle. Intermittent means a connection that is nearly good, so work along the path it travels.

• Flex the cable at both ends while watching the cursor. A break inside the sleeve shows up as a cut-out exactly when the cable moves, and it only gets worse.
• Move the receiver, or the mouse, away from the hub. A wireless mouse that randomly stops working is usually losing its 2.4 GHz link to distance, metal, or a USB 3 port sitting next to the receiver.
• Try a port directly on the motherboard. Front-panel headers, hubs and monitor ports all drop devices under load in a way a rear port usually does not.

If the cut-outs survive a different cable, port and computer, the fault is inside the mouse. The polling rate test makes it visible: a healthy mouse holds a steady report rate, while one that drops out reads unevenly even when the average looks right.

It works, then stops after a few minutes idle

This specific pattern — fine while you are using it, dead after you step away, alive again a second after you jiggle it — is almost always Windows powering the port down to save energy, not a failing mouse. It is worth knowing because it looks exactly like a hardware fault and no amount of driver reinstalling touches it.

• In Device Manager, open the mouse under "Mice and other pointing devices", go to the Power Management tab, and clear "Allow the computer to turn off this device to save power". Do the same for each USB Root Hub.
• In Control Panel → Power Options → your plan → Advanced settings, set USB selective suspend to Disabled.

Two port-level fixes worth trying early

• Move a wired mouse or receiver from USB 3 to a USB 2 port. USB 3 ports are a documented source of 2.4 GHz interference and some receivers behave noticeably better on USB 2.
• Unplug the receiver, wait about ten seconds, and plug it back in. That is often enough to make Windows enumerate the device again. For Bluetooth, turn Bluetooth off, wait a few seconds, and turn it back on before trying to re-pair.

When it is worth reinstalling the driver

Driver problems are a much rarer cause than the internet suggests — most mice use a generic driver that Windows supplies and that rarely breaks. It is worth trying when the mouse works in the firmware setup screen before Windows loads but not afterwards, or when it stopped immediately after a Windows update.

In Device Manager, remove the mouse under "Mice and other pointing devices" and reboot; Windows reinstalls it automatically. It is also worth looking in Settings → Windows Update → Advanced options → Optional updates, where mouse, HID and chipset driver updates appear that the normal update never offers. If you have the manufacturer's utility installed and the mouse is behaving oddly, uninstalling that utility is worth trying too — it overrides Windows' own handling.

When to stop and replace it

A mouse is worth replacing rather than repairing when a switch has failed and it is out of warranty, when the cable is damaged inside, or when the sensor drops out on every surface you try. All three are physical wear, and none is fixed by software. If the tester shows a button that never registers, or a tracking line full of gaps on a clean mousepad, you have your answer. One thing that is not a fault: a cursor that moves too fast or too slowly is a mouse DPI setting, and nothing is broken.

Frequently asked questions

Why is my PC not detecting my mouse?

Try a different USB port directly on the computer rather than a hub or monitor, and on a wireless mouse replace the battery before anything else — a dying battery causes more of these than any driver fault. If the sensor light is off entirely the mouse has no power, which points at the cable, the port or the battery. Testing it on a second computer settles whether the mouse or the machine is at fault.

How do I fix my mouse problem?

Identify the symptom first, because the fixes are unrelated: nothing at all is power or cable, a jumping cursor is surface or interference, a dead button is a failed switch, and self-double-clicking is a worn switch. Run a button and tracking test to find out which you have. Only the first two have software fixes; the other two are hardware.

Why does my mouse work then stop after a few minutes?

That specific pattern is almost always Windows powering the USB port down to save energy, not a failing mouse. In Device Manager, open the mouse and each USB Root Hub, go to Power Management and clear the option allowing the computer to turn the device off to save power. Then set USB selective suspend to Disabled in your power plan advanced settings.

Why is my mouse not clicking?

If a button registers nothing in a click test, the switch has failed and no setting will bring it back. Before concluding that, check the buttons have not been remapped in your mouse software, and that the primary and secondary buttons have not been swapped in Windows. Side buttons that do nothing may simply not exist on your mouse, or be blocked by your browser.

Is my mouse battery dead?

A dying battery usually shows as a sensor light that is off or flickering, a cursor that moves erratically, or a mouse that disconnects and reconnects. Replace or charge it before investigating anything else — battery problems get misdiagnosed as driver faults constantly, and rechargeable mice often behave strangely well before they report being empty.

Can a mouse be repaired?

Often yes, if you are willing to open it. A failed click switch can be desoldered and replaced for very little money, and a worn scroll encoder can sometimes be cleaned. A cable damaged inside the housing and a failing sensor are usually not worth the effort. If it is still under warranty, claim it rather than opening it, since that voids the cover.

How do I reset a mouse?

Most mice have no reset as such. For a wireless mouse, switch it off, unplug the receiver, wait about ten seconds, reconnect and switch it back on; for Bluetooth, remove the pairing in Windows and pair again. Manufacturer software such as G HUB or Synapse can reset the on-board profile to defaults, which undoes accidental button remapping.

How to repair a laptop touchpad that stopped working?

Check the function key that disables it first, since it is easy to press by accident, and note that many laptops switch the touchpad off automatically while a USB mouse is connected. Then confirm it is enabled in Settings, and if not, remove the device in Device Manager and reboot so Windows reinstalls it. Physical damage is a service job rather than a home repair.

When should I replace a mouse instead of fixing it?

When the cable is damaged inside the housing, when the sensor drops out on every surface you try, or when several switches are failing at once — all three are physical wear that software cannot address. A single button double-clicking is the exception: that is one small component, and replacing it is far cheaper than replacing the mouse.
