How to Fix a Mouse That’s Not Working

A mouse not working is the failure of a wired or wireless mouse to move the cursor or register clicks on a Windows computer, and the most common cause is a loose USB connection or a drained wireless battery. Other frequent causes include a corrupted mouse driver, a dirty optical or laser sensor, an unsuitable tracking surface, USB selective suspend cutting power to the port, a worn switch that double-clicks, and a Fast Startup glitch. This article explains what causes a mouse to stop working, then gives the step-by-step fixes that resolve most cases.

Each fix names the exact Windows tool, including Device Manager, the mouse pointer settings, USB selective suspend, and manufacturer software for gaming mice. The fixes are ordered from the most common and least disruptive, such as testing another port and replacing batteries, to sensor cleaning and pointer adjustments.

Apply the fixes in order and test cursor movement and clicks after each one, because a single connection, battery, sensor, or driver fault usually accounts for the failure. Wired and wireless mice are covered separately where the steps differ.

What Causes a Mouse to Stop Working?

A mouse stops working when the movement or click signal cannot reach Windows, either because the connection fails, the sensor cannot track, or software blocks the input. The causes below are ranked from most to least common.

• A loose USB connection or faulty port. A wired mouse on a damaged port or a loose cable moves no cursor.
• Drained batteries or an unpaired dongle. A wireless mouse with dead batteries or a dropped receiver link registers no movement.
• A corrupted mouse driver. A damaged or outdated driver stops Windows from reading cursor movement and clicks.
• A dirty sensor or an unsuitable surface. Dust on the optical or laser lens, or a glossy or transparent surface, stops the sensor from tracking.
• USB selective suspend. A power-saving setting that suspends the USB port cuts power to the mouse until it is moved repeatedly.
• A worn switch causing double-clicks or jitter. A degraded micro-switch registers one press as two clicks or drops clicks entirely.
• A Fast Startup glitch. The hybrid shutdown can leave the mouse driver uninitialized on the next boot.

Test the Mouse on Another Port or Computer

Moving the mouse to a different USB port or a second computer separates a port fault from a mouse fault quickly. A wired mouse depends on a working USB port and cable.

1. Unplug the mouse and connect it to a different USB port directly on the computer rather than a hub.
2. Move the mouse from a front-panel port to a rear-panel port on a desktop, because rear ports connect directly to the motherboard.
3. Connect the mouse to a second computer to confirm whether the mouse or the original port is at fault.
4. Test a known-working mouse on the original port to check the port itself.
5. Bypass any USB hub or adapter, because an underpowered hub can stop a mouse from tracking.

If the mouse works on another port or computer, the original USB port is the fault. The differences between USB port generations are covered in the guide to types of computer ports.

Replace the Batteries and Re-Pair a Wireless Mouse

Replacing the batteries and restoring the wireless link revives a wireless mouse that has stopped tracking. A wireless mouse fails when the battery drains or the receiver pairing drops.

1. Replace the batteries with fresh ones, or fully charge a rechargeable mouse before testing.
2. Confirm the power switch on the underside of the mouse is set to On.
3. For a 2.4GHz mouse, reseat the USB receiver in a port near the mouse and press the connect button on the receiver and the mouse.
4. For a Bluetooth mouse, open Windows Settings, select Bluetooth and devices, remove the mouse, then add it again through Add device.
5. Move the receiver away from USB 3.0 ports and metal surfaces that interfere with the 2.4GHz signal.

Keep the mouse within the rated range of its receiver to maintain a stable signal. The trade-offs between connection types are explained in the comparison of wired and wireless peripherals.

Reinstall the Mouse Driver in Device Manager

Reinstalling the mouse driver in Device Manager replaces a corrupted driver that stops Windows from reading movement and clicks. Windows reinstalls a standard mouse driver automatically after removal.

1. Open Device Manager by pressing the Windows key and X and selecting it from the menu.
2. Expand the Mice and other pointing devices section.
3. Right-click the affected mouse and select Uninstall device.
4. Confirm the removal, then restart the computer.
5. Allow Windows to detect the mouse and reinstall the driver during startup.

When the mouse still fails, open Device Manager again, right-click the mouse, and select Update driver to install the manufacturer driver. The internal parts that generate the movement signal are described in the guide to how computer mice work.

Clean the Sensor and Use an Opaque Surface

Cleaning the optical or laser sensor and switching to an opaque surface restores tracking when the cursor moves erratically or not at all. The sensor reads surface texture, which dust and reflective surfaces disrupt.

1. Turn the mouse over and inspect the sensor lens on the underside.
2. Blow compressed air across the lens and wipe it with a dry lint-free cloth.
3. Remove hair or fibers caught around the sensor opening.
4. Place the mouse on an opaque mouse pad rather than glass, gloss, or a transparent surface.
5. Test cursor movement across the full pad to confirm even tracking.

An optical sensor fails on glass and mirrored surfaces, while a laser sensor tracks on more materials but still skips on transparent glass. A fabric or hard plastic mouse pad gives the sensor consistent texture to read.

Disable USB Selective Suspend

Disabling USB selective suspend stops Windows from cutting power to the mouse port during a power-saving state. The setting sits in the advanced power plan options.

1. Open Control Panel, then Hardware and Sound, then Power Options.
2. Select Change plan settings for the active plan, then Change advanced power settings.
3. Expand USB settings, then USB selective suspend setting.
4. Set the value to Disabled for both On battery and Plugged in.
5. Apply the change and restart to confirm the mouse no longer drops out.

A mouse that freezes after the computer is idle and recovers only after several movements points directly to USB selective suspend. Disabling the setting keeps power flowing to the port at all times.

Fix Double-Clicking and Cursor Jitter

Adjusting the click and pointer settings, then addressing a worn switch, corrects a mouse that double-clicks on a single press or jitters. A degraded micro-switch and an aggressive double-click speed both produce false clicks.

1. Open Control Panel, select Mouse, and lower the Double-click speed slider on the Buttons tab to reduce accidental double-clicks.
2. Update the mouse firmware through the manufacturer software, because some makers ship a debounce fix.
3. Test the mouse on a second computer to confirm the double-click follows the hardware.
4. Replace or repair the micro-switch when the double-click persists across computers, because the switch is worn.
5. For jitter, clean the sensor and confirm the surface, because a dirty lens causes the cursor to drift.

Adjust Pointer Speed and Precision

Setting the pointer speed and enhanced precision corrects a cursor that moves too slowly, too fast, or inconsistently. The pointer options control how movement maps to cursor distance.

1. Open Control Panel and select Mouse, then the Pointer Options tab.
2. Set the Select a pointer speed slider to the middle and adjust to preference.
3. Clear Enhance pointer precision to stop variable acceleration on a gaming mouse.
4. Confirm the in-app or in-game sensitivity is set separately from the Windows speed.
5. Test cursor travel across the full screen to confirm even movement.

A high-DPI gaming mouse stores its sensitivity in onboard memory, so the pointer speed is set in both Windows and the manufacturer software for consistent movement.

Update Software for a Gaming Mouse

Installing the manufacturer software restores the extra buttons, DPI stages, and lighting on a gaming mouse that a standard driver does not control. Gaming mice depend on their own software for full function.

• Install the maker software. Use Logitech G HUB, Razer Synapse, Corsair iCUE, or the matching application for the mouse brand.
• Update the mouse firmware. Apply any firmware update the software offers, because it can fix tracking and button faults.
• Reassign the extra buttons. Map the side and DPI buttons in the software when they stop responding.
• Save settings to onboard memory. Store the configuration on the mouse so it works without the software running.

Mouse Symptoms and Their Causes

Key Takeaways

• Check the connection or batteries first. A loose USB port on a wired mouse and dead batteries on a wireless mouse cause most failures.
• Clean the sensor and check the surface. A dirty lens or a glossy surface stops the optical or laser sensor from tracking.
• Disable USB selective suspend for dropouts. The power-saving setting cuts power to an idle mouse port.
• Treat double-clicks as a worn switch. A double-click on one press that follows the mouse across computers means the micro-switch is degraded.
• Install maker software for gaming mice. The extra buttons and DPI stages need the manufacturer application.

Last Thoughts on a Mouse Not Working

A mouse not working is resolved by checking the connection or batteries first, then moving through the driver, sensor, power, and pointer checks in order. A wired mouse depends on a working USB port, while a wireless mouse depends on fresh batteries and an intact pairing, and any mouse depends on a clean sensor and an opaque surface.

When the mouse is one of several dead input devices, the steps to fix a keyboard that is not working and to resolve a USB device not recognized apply to the shared connection. The sensor and switch behavior covered here builds on the explanation of how computer mice work, and a full index of input faults sits in the hub of common PC problems.
