Windows 11 mouse not detected: how to get it working again

If Windows 11 suddenly stops detecting your mouse, the problem is usually the mouse itself, the USB or Bluetooth connection, or a Windows setting or driver issue. Start with the safest fixes first: unplug and replug it, try a different port, replace weak batteries, restart Windows, and check Device Manager. If the mouse works on another PC but not this one, the fix is usually in Windows or the connection path, not the mouse.

Before you start

This applies to Windows 11 on home and work PCs with wired USB mice, wireless USB dongles, and Bluetooth mice. You do not need Administrator rights for the first checks, but Device Manager changes and driver work may require them.

You may need to restart Windows during troubleshooting. If you are worried about losing work, save open files first. No backup is usually needed for these checks, since the early steps are reversible.

Start with two safe checks: confirm the mouse has power, and try another USB port or another device connection method if you have one available.

What’s happening when Windows 11 doesn’t detect your mouse

The usual signs are simple: the pointer does not move, clicks do nothing, or a wireless mouse seems dead even though it used to work.

The pointer does not move or clicks do nothing.

Sometimes the mouse works in one place, but not another, such as in Windows after sign-in but not on the lock screen, or in one USB port but not another.

A wired mouse that goes dark right after you plug it in often points to a port, cable, or power issue. A wireless mouse that stopped working overnight is often just a battery, receiver, or sleep issue. If the mouse still responds in BIOS, in another PC, or in a different user account, Windows is less likely to be the root cause.

Is it the mouse, the USB port, or Windows itself?

Start by separating the problem into parts. If the mouse works on another computer, the mouse itself is probably fine. If another mouse works in the same USB port, the port is probably fine. If a Bluetooth mouse won’t pair or wake up, check whether Bluetooth is on and whether the mouse actually has power.

For a quick check on a Bluetooth mouse:

• Make sure the mouse’s power switch is on.
• Replace or recharge the battery.
• Confirm the mouse is in pairing mode if it is a new pairing.
• Test Bluetooth with another device, such as headphones or a phone, if you already have one paired before.

For a USB mouse:

• Try the mouse in a rear port on a desktop PC, not just a front-panel port or hub.
• Try a different cable if the mouse uses a detachable one.
• If it uses a wireless dongle, try the dongle in a different port.

Start with the safest fixes first

Do the low-risk fixes first. They solve a surprising number of cases and do not make things worse.

1. Unplug the mouse or receiver, wait a few seconds, and plug it back in.

The mouse reconnects and the pointer moves again.

If nothing changes, try a different USB port.

2. Move a wired mouse to another USB port, preferably one directly on the PC.

Windows should make a sound or show that new hardware was detected.

If the mouse works in one port but not another, the bad port is likely the issue.

3. Replace or recharge the batteries in a wireless mouse.

The mouse wakes up and reconnects within a few seconds.

If the light is on but the mouse still does nothing, continue.

4. Wake the mouse and restart Windows.

Shut down or restart the PC from the keyboard if needed, then start it again. Many sleep-related problems clear after a full restart.

5. If you use a wireless dongle, try another port for the dongle and avoid USB hubs for the test.

If the mouse starts working through the new port, the old port or hub was probably the weak point.

Check Windows 11 settings and Device Manager

If the mouse still is not detected, check Windows itself. You may need to do this from the keyboard if the mouse is unusable.

First, make sure Bluetooth is enabled if you are using a Bluetooth mouse.

Settings > Bluetooth & devices > Bluetooth

Turn Bluetooth on, then check whether the mouse appears under connected devices. If it does not, remove it and pair it again only if the mouse is already powered and in pairing mode.

Next, open Device Manager and look for the mouse or the Bluetooth adapter.

Right-click Start > Device Manager > Mice and other pointing devices / Bluetooth

What to look for:

• A device with a warning symbol
• A disabled device
• A missing or generic driver entry
• A Bluetooth adapter with an error under Bluetooth

If a mouse entry is disabled, enable it. If there is a warning symbol, Windows may have a driver problem or a connection problem. If the Bluetooth adapter is missing or disabled, the mouse cannot connect properly until that is fixed.

What to do if the mouse still won’t show up

If the basic checks failed, move to the next layer.

1. Reinstall the mouse or Bluetooth device from Device Manager.

Use the keyboard to open Device Manager, select the mouse or adapter, and choose uninstall if the device looks corrupted. Then restart Windows so it reloads the driver.

Device Manager > right-click the device > Uninstall device

If the mouse returns after restart, the driver entry was the problem.

2. Run Windows Update.

Settings > Windows Update > Check for updates

Install any pending updates, then restart. A recent update can also fix a broken driver path, and in some cases a recent update is what caused the problem in the first place.

3. Unplug other USB devices for a test.

A flaky hub, dock, webcam, or storage device can interfere with power or USB enumeration. Leave only the mouse and keyboard connected, then test again.

4. Turn off USB power saving for the test.

Control Panel > Power Options > Change plan settings > Change advanced power settings > USB settings > USB selective suspend setting

Set it to disabled temporarily, then test sleep and wake again. If that fixes the problem, power saving was putting the port to sleep too aggressively.

If the mouse only fails on the login screen, after sleep, or after an update, focus on this section first. A login-screen failure often points to a Bluetooth or driver issue. A failure after sleep points to USB selective suspend, the dongle, or the Bluetooth adapter not waking cleanly. A failure after an update usually means a driver changed or Windows reset a power setting.

How to tell the fix worked

You want clear signs, not just a one-time flicker.

A fix worked if the pointer moves normally, clicks register every time, and the mouse still works after a restart or sleep/wake cycle. For a wireless mouse, the connection should come back without having to unplug the dongle again. In Device Manager, the device should appear without warning symbols or error markers.

If the mouse works only for a few seconds and then dies again, the real issue is often power, a flaky cable, or a bad port rather than Windows itself. If it only works after a restart but not after sleep, focus on power settings and driver updates. If it works in one USB port and not another, stop chasing Windows and treat it like a port problem.

Why this keeps happening again

Repeat failures usually come from a small set of causes. Weak batteries are the most common for wireless mice. Cheap USB hubs and docking stations are another common source, especially if the mouse disconnects when the PC wakes up.

Sleep mode can also cause trouble. Windows may power down the USB controller or Bluetooth adapter, and then the mouse never wakes cleanly. Driver updates can change that behavior too, especially after a Windows update or a manufacturer utility update.

To reduce repeat problems:

• Replace batteries before they get very weak.
• Plug the dongle into a direct USB port instead of a hub when you can.
• Avoid moving the receiver between ports constantly.
• Keep Windows and chipset/Bluetooth drivers up to date.
• If sleep is the trigger, test a different power plan or USB power setting.

When the mouse is probably hardware failure

At some point, more troubleshooting just wastes time. A bad mouse is likely if it fails on more than one PC, with more than one port, or with fresh batteries. A broken wireless receiver is likely if the mouse works nowhere but the dongle is not detected either. A damaged USB port is likely if several devices fail in the same port, or the plug feels loose.

For Bluetooth, suspect the adapter if Bluetooth devices stop connecting across the board, not just one mouse. If the mouse only fails through Bluetooth but works with its USB receiver, the Bluetooth adapter or stack is the better suspect.

Replacement makes more sense than more troubleshooting when the mouse is dead everywhere, the receiver is lost or broken, or the port physically will not hold a connector. If the mouse works on another machine and every fix on this PC fails, the problem is usually in the PC’s port, Bluetooth adapter, or driver path rather than the mouse body itself.

Conclusion

If the mouse is still dead after the port, battery, restart, Device Manager, and update checks, test the mouse on another PC and test a different mouse on this one. That tells you whether to replace the mouse, the dongle, or the PC’s USB or Bluetooth hardware next.
