Quick answer

Confirm that the mouse uses Bluetooth, then check its power and try it close to the PC. Keep a working touchpad or wired mouse available. If several accessories drop together, run the Windows Bluetooth diagnostics. If it happens only after sleep, check the adapter’s optional power setting. Re-pair only the affected mouse, once.

Choose the check that matches your symptom

Start with the row that describes what you see. You do not need to try every step.

Before you start

  • Not sure which Windows you have? In Settings, open System, then About and read Windows specifications. These steps target Windows 11; use the manufacturer’s instructions for another system.
  • Note the mouse and computer models, whether failure follows idle/sleep, whether another input still works and what you already tried. Keep serial numbers and personal device names private.
  • Have a working touchpad, touchscreen or suitable wired input before removing a pairing or changing an adapter setting. Ask workplace IT about managed equipment.
  • Check the mouse’s own manual for its charging, battery, channel and pairing controls. A small USB receiver is not proof that a mouse uses Bluetooth.

Why this happens

A mouse that loses power, a crowded wireless environment, a damaged pairing and a sleeping Bluetooth adapter can look similar. If a touchpad still works, Windows is not necessarily frozen. If several Bluetooth devices fail together, replacing one mouse may leave the shared problem untouched.

What to do, step by step

Try one step at a time. Stop when the issue is resolved. If an instruction doesn't match your device, use the official model-specific guidance instead.

1

Check the mouse’s power and connection type

  1. Charge the mouse or fit the correct fresh batteries for that model. Turn it off and back on.
  2. Check which connection mode or channel is selected. If the mouse uses a USB receiver, reseat the receiver and test a different USB data port instead of changing Windows Bluetooth settings.
  3. Retest the same task. If all input stops at once, stop treating it as a mouse-only fault.
Use a charger or battery type approved for that model. Do not pry open a sealed mouse or guess a factory-reset button combination.
2

Compare range and possible interference

  1. Use the mouse close to the PC with a clear path between them.
  2. Move it away from USB 3 equipment and a crowded dock. Repeat the same task to compare.
  3. When the pointer stops, check whether the touchpad or another input still responds.
A better result in one position is useful evidence, not proof of which component failed. Borrow existing equipment for comparison before buying anything.
3

Run the Bluetooth diagnostics in Get Help

  1. Open Start, search for Get Help and open the Microsoft app.
  2. Search for Bluetooth troubleshooting in the app and follow its diagnostic prompts.
  3. Retest the mouse. Note whether a second Bluetooth accessory drops at the same time.
Use the built-in Microsoft app. Avoid advertisements for driver-repair utilities. Ask IT if the PC is managed.
4

Re-pair only the intended mouse, once

  1. Make sure another input works. Open Start > Settings > Bluetooth & devices > Devices.
  2. Beside your mouse, open the three-dot More options menu. Choose Remove device, then Yes.
  3. Use the mouse’s documented pairing control to make it discoverable.
  4. Select the network, sound or battery area by the taskbar clock. Use the Manage Bluetooth devices arrow on the Bluetooth tile.
  5. Under New devices, choose your mouse and select Done if prompted. Retest.
Removing a pairing temporarily disconnects the mouse. Do not remove the keyboard, disable the whole radio or guess a model-specific pairing sequence. If you already tried this, keep that result and move on.

For idle-related drops, inspect the adapter’s power option

  1. Keep a second input available. Search Start for Device Manager and expand Bluetooth.
  2. Right-click the actual Bluetooth adapter (not the mouse) and choose Properties. Open Power Management if present; skip this step if there is no such tab.
  3. Note the original setting. Clear Allow the computer to turn off this device to save power, then choose OK.
  4. Test the same idle or sleep cycle. Restore the original setting if the change does not help.
The tab is not available on every adapter. If it is absent, skip this change; do not create it through registry edits. The change can affect battery use. Keep the original setting so you can restore it if it does not help.

Use the correct adapter’s official driver route

  1. In Device Manager, expand Bluetooth. Right-click the identified Bluetooth adapter and choose Update driver.
  2. Select Search automatically for drivers. If that does not help, check for a driver for the exact PC model from its maker, or ask IT for a managed device.
  3. Save open work before restarting if asked, then retest. If the problem began right after a driver update, tell the maker or IT before trying a rollback.
Windows reporting a driver is current does not prove that no newer OEM driver exists. Ask the maker or IT about a supported rollback; do not uninstall the adapter, flash firmware or install a random driver bundle to experiment.

Still not working? Know when to stop

Stop if every input is failing, you cannot identify the adapter, a required control is missing or the machine is managed. If a charged mouse fails on another compatible computer too, contact its maker; if several Bluetooth devices fail only on one PC, ask the PC maker or IT about that shared system. Provide the models, Windows version, failure timing, diagnostic result and checks already completed. Do not reset Windows, weaken security or repeat the same pairing cycle indefinitely.

Write down the exact model and error message before contacting official support.

Useful tools, only if they fit your situation

Try the free checks first. Compare these optional products for the specific uses below; buying equipment does not guarantee a fix.

Start with a mouse you already have or can borrow. If the entire PC freezes or several Bluetooth accessories fail, do not buy a new mouse to repair that shared problem. These options are useful only when a wired or separate receiver connection fits what your tests found.

  • Direct wired comparisonOptional

    Razer Pro Click V2

    Use a direct USB data connection to bypass Bluetooth and wireless interference while testing the pointer.

    • True wired input with the included USB-A to USB-C data cable.
    • Bluetooth and 2.4 GHz receiver modes are also available.

    Consider only when: A borrowed wired mouse works and you want a premium replacement that can operate over a cable as well as wirelessly.

    Check compatibility: Right-handed shape. Wired mode needs a USB-A data port for the included cable. Set the mode switch to Wired/Off for the wired test.

    Logitech MX Master 4 for Business (Graphite)

    Use the included Logi Bolt receiver to avoid pairing the mouse through Windows Bluetooth settings.

    • This Business listing includes a Logi Bolt USB-C receiver.
    • MagSpeed scrolling and haptic feedback provide additional control features.

    Consider only when: Tests isolate the drops to Bluetooth pairing and you prefer wireless use with a separate USB receiver.

    Check compatibility: Windows 11 and a USB-C data port for the included receiver. The receiver is still wireless and cannot rule out interference; do not use its charging cable as a wired-mouse test.

Frequently asked questions

Why does the mouse disconnect after being idle?

Battery state, the mouse’s own sleep behavior, adapter power management and a driver problem are different possibilities. Compare what happens after wake before deciding which setting to change.

What if Power Management is missing?

Skip that optional step. Adapter and driver interfaces differ; a missing tab is not an instruction to alter the registry or install an unofficial driver.

Is a USB wireless receiver the same as Bluetooth?

No. A mouse can use a dedicated receiver, Bluetooth or selectable connection modes. Identify the chosen mode before following pairing instructions.

Should I remove and pair the mouse every time?

A single controlled re-pair can test that relationship. If it repeatedly fails, keep the outcome and investigate the shared radio, driver, power or mouse rather than restarting the same loop.

Will buying a Bluetooth adapter or a new mouse fix it?

Not necessarily. A missing or failed Bluetooth radio, a mouse fault and interference require different responses. Use a compatible loaner or existing input for comparison before a purchase.
