It’s best to kick things off by working through the quick fixes below. You might be dealing with a trivial issue that doesn’t require advanced troubleshooting.

  • Endurræstu tölvuna þína: Usually, restarting your computer is all it takes to resolve problems in Windows. Save your work and select Home > Power > Endurræsa to perform a system reboot.
  • Turn Your Mouse Off & On: Likewise, it’s a good idea to restart the device firmware of the Bluetooth mouse. Locate the Power switch on the Bluetooth mouse and set it to Off, þá On.
  • Move Your Mouse Closer: Bluetooth devices don’t function well at a distance. Reduce the gap between your computer and mouse if you use them far apart. 
  • Eliminate Bluetooth Interference: Make sure that there are no sources of Bluetooth interference (e.g., usually other wireless devices) nearby or between your computer and mouse.
  • Endurhlaða músina: A mouse with little charge remaining can weaken its Bluetooth signal. Connect your mouse to a USB port to recharge it or insert fresh batteries.
  • Switch to Another Surface: Avoid smooth surfaces to improve cursor control. 

Keyra Bluetooth bilanaleit

Windows 11 comes with a built-in Bluetooth troubleshooter that can automatically detect and fix connectivity issues with Bluetooth devices. To run it:

1. opna Home valmyndinni og velja Stillingar.

2. Skrunaðu niður System settings and select the option labeled leysa.

3. Veldu Aðrir úrræðaleitir.

4. Skrunaðu niður og veldu Hlaupa hnappur við hliðina á Bluetooth. 

Install Support Software & Drivers

Bluetooth pointing devices work best with additional support software and mouse drivers—Logitech valkostir, Razer Synapse, etc. Look up the Bluetooth mouse model online and install any applicable software from the manufacturer.

If you’ve already done that, update the software (visit the application’s settings page and look for a Athugaðu með uppfærslur option or something similar) and see if that eliminates the lag.

Disable Power Management for Bluetooth Adapter

If your Bluetooth mouse lags when left idle for a few seconds, use the Device Manager in Windows 11 to disable power management for the PC’s Bluetooth module.

1. Hægri smelltu á Home hnappinn og veldu Tækjastjórnun.

2. Stækkaðu Bluetooth category, right-click the Bluetooth module—e.g., Intel(R) Wireless Bluetooth(R)— og veldu Eiginleikar.

3. Skiptu yfir í Power Management flipann og hakið úr reitnum við hliðina á Allow the computer to turn off the device to save power. Veldu síðan OK.

If that fails to resolve the issue, expand the Mannleg viðmótstæki category (further down the Device Manager) and open the Eiginleikar pane for Bluetooth Low Energy GATT compliant HID. Skiptu síðan yfir í Power Management tab and clear the box next to Allow the computer to turn off the device to save power.

Disable Bluetooth Power Management by Modifying Registry Keys

If the above fix doesn’t help, you must modify a set of registry keys related to Bluetooth power management via the Windows 11 Registry Editor. However, since accidental changes can break the operating system, we recommend backing up the system registry áður en haldið er áfram.

1. Ýttu á Windows + R to open the Run box. Then, type ríkisstjóratíð og ýttu Sláðu inn.

2. Navigate to the following folder on the Registry Editor’s left pane:

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > enum > USB

Next, expand the folder that begins with VID_8087 (td VID_8087&PID_0026) and then the sub-folder with the numbers and letters (e.g., 5&ed1e05a&0&10). Finally, select Færibreytur tækisins.

3. Double-click each of the following keys on the right side of the Registry Editor window, add a hexadecimal value of 0Og veldu OK.

  • DeviceSelectiveSuspended
  • SelectiveSuspendEnabled
  • SelectiveSuspendSupported

Athugaðu: If any of the keys above appear missing, right-click a vacant area and select nýtt > DWORD (32-bita) Gildi. Then, name it as the absent key and save it with a hexadecimal value of 0.

Switch Performance Plan

Another way to avoid Bluetooth mouse lag caused by PC power management is to configure your Windows 11’s default power mode for best performance. However, that can hurt the battery life of laptop devices.

1. opna Home valmynd og velja Stillingar.

2. Select the category labeled Rafmagn og rafhlaða.

3. Opnaðu fellivalmyndina við hliðina á Kraftstilling og velja Besta frammistaða.

Remove and Reconnect Bluetooth Mouse

The following fix involves removing and reconnecting your Bluetooth mouse or trackpad. That should help eliminate issues with a corrupt Bluetooth device configuration.

1. opna Start valmyndinni og velja Stillingar.

2. Veldu Bluetooth og tæki on the Settings sidebar. 

3. Veldu Meira icon (three dots) next to your Bluetooth mouse and select Fjarlægðu tækið > Já.

4. Veldu Bæta tæki.

5. Veldu Bluetooth and repeat the pairing process to re-establish the Bluetooth connection between your mouse and computer.

Check for Bluetooth Driver Updates

If the mouse lag problem persists, download the latest Bluetooth drivers from your PC manufacturer—Dell, HP, Acer, etc. Then, run the setup file within the downloaded package or perform the update via the Device Manager.

1. opna Tækjastjórnun.

2. Stækkaðu Bluetooth flokki.

3. Right-click the Bluetooth module and select Uppfærðu bílstjóri.

4. Veldu Browser my computer for drivers.

5. Veldu Vafra and locate the downloaded driver package on your computer. Then, select Næstu til að framkvæma uppfærsluna.

Uninstall and Reinstall Bluetooth Drivers

If you can’t find newer updates, try removing and reinstalling the Bluetooth driver for your PC. Make sure to use a wired mouse to interact with the GUI in the meantime.

1. opna Tækjastjórnun.

2. Stækkaðu Bluetooth flokki.

3. Right-click the Bluetooth module and select Uninstall tæki.

4. Merktu við reitinn við hliðina á Reyndu að fjarlægja bílstjórann fyrir þetta tæki og velja Uninstall.

5. Restart your computer. Windows 11 will automatically reinstall the Bluetooth driver at startup. If it doesn’t, re-open the Tækjastjórnun og velja aðgerð > Skannaðu eftir breytingum á vélbúnaði.

Uppfærðu grafíkbílstjóra

Outdated video drivers can also result in a laggy mouse pointer. Check the card manufacturer’s website (NVIDIA, AMD, Intel, etc.) for possible updates. Alternatively, use a third-party driver updater tool or Windows Update to acquire the latest video drivers for your PC (more on that next).

Uppfærðu Windows 11

If the Bluetooth mouse lag persists, try updating Windows 11 to its latest version. That should patch out any known issues in the operating system that prevent Bluetooth devices from functioning correctly.

1. opna Start valmyndinni og velja Stillingar.

2. Veldu Windows Update on the Settings sidebar.

3. Veldu Athugaðu með uppfærslur.

4. Veldu Hlaða niður núna til að setja upp tiltækar uppfærslur.

Additionally, select Frekari möguleikar > Valfrjálsar uppfærslur and install any Microsoft-verified driver updates for the Bluetooth mouse, the Bluetooth module, and the graphics card.

Leitaðu að malware

Computer viruses are another reason that induces mouse or touchpad lag. Use the built-in Windows Öryggi tool (accessible via the system tray) or a dedicated anti-malware utility-eins og Malwarebytes—to thoroughly scan your PC for malware.

Slökktu á fljótur gangsetning

Next up, consider disabling Fast Startup in Windows 11. It helps boot up your PC faster and has a history of causing problems with input devices.

1. opna Home valmynd, tegund Stjórnborðog ýttu á Sláðu inn.

2. Veldu Vélbúnaður og hljóð.

3. Undir Power Options kafla, veldu Veldu hvað máttur hnappar gera.

4. Veldu Breyttu stillingum sem eru ekki tiltækar.

5. Uncheck the box next to Kveiktu á hraðvirkni (mælt með) and select Save changes.

Hvað annað geturðu gert?

If none of the fixes above work, here are a few other things to try:

  • Use the Bluetooth mouse as a standard wireless mouse. Logitech mice, such as the Logitech MX Master, come with a unifying receiver that offers better connectivity than Bluetooth. 
  • Run an SFC or a DISM scan to resolve underlying problems with your Windows 11 PC. 
  • Pair and use the Bluetooth mouse on another computer (PC or Mac). If the mouse lag issue persists, you’re likely dealing with a defective device—send it back for a replacement if it’s still under warranty. If not, continue troubleshooting your PC in Safe Mode.
