Kokeile näitä pikakorjauksia ensin

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.

  • Käynnistä tietokoneesi uudelleen: Usually, restarting your computer is all it takes to resolve problems in Windows. Save your work and select Aloita > teho > Käynnistä uudelleen 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 teho switch on the Bluetooth mouse and set it to pois, sitten 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.
  • Lataa hiiresi: 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. 

Suorita Bluetooth-vianmääritys

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

1. Avaa Aloita valikkoon ja valitse Asetukset.

2. Vieritä alas järjestelmä settings and select the option labeled vianmääritys.

3. valita Muut vianmääritysohjelmat.

4. Vieritä alas ja valitse ajaa -painiketta vieressä Bluetooth:. 

Install Support Software & Drivers

Bluetooth pointing devices work best with additional support software and mouse drivers—Logitech Valinnat, 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 Tarkista päivitykset 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. Napsauta hiiren kakkospainikkeella Aloita painiketta ja valitse Laitehallinta.

2. Laajenna Bluetooth: category, right-click the Bluetooth module—e.g., Intel (R) langaton Bluetooth (R)– ja valitse Kiinteistöt.

3. Vaihda Power Management -välilehti ja poista valinta vieressä olevasta ruudusta Anna tietokoneen sammuttaa laitteen virran säästämiseksi. Valitse sitten OK.

If that fails to resolve the issue, expand the Human Interface Devices category (further down the Device Manager) and open the Kiinteistöt pane for Bluetooth Low Energy GATT compliant HID. Vaihda sitten kohtaan Power Management tab and clear the box next to Anna tietokoneen sammuttaa laitteen virran säästämiseksi.

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 ennen etenemistä.

1. Lehdistö Windows + R to open the Run box. Then, type regedit ja paina enter.

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 (esim, VID_8087&PID_0026) and then the sub-folder with the numbers and letters (e.g., 5&ed1e05a&0&10). Finally, select Laitteen parametrit.

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

  • DeviceSelectiveSuspended
  • SelectiveSuspendEnabled
  • SelectiveSuspendSupported

Huomautuksia: If any of the keys above appear missing, right-click a vacant area and select Uusi > DWORD (32-bittinen). 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. Avaa Aloita menu ja valitse Asetukset.

2. Select the category labeled Virta ja akku.

3. Avaa vieressä oleva avattava valikko Virrankulutus ja valitse Paras suorituskyky.

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. Avaa Käynnistä-valikon ja valitse Asetukset.

2. valita Bluetooth ja laitteet on the Settings sidebar. 

3. Valitse Lisää: icon (three dots) next to your Bluetooth mouse and select Poista laite > Kyllä.

4. valita Lisää laite.

5. valita 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—notko, HP, Acer, etc. Then, run the setup file within the downloaded package or perform the update via the Device Manager.

1. Avaa Laitehallinta.

2. Laajenna Bluetooth: luokka.

3. Right-click the Bluetooth module and select Päivitä ohjain.

4. valita Selaa tietokoneeni ohjaimia varten.

5. valita selailla and locate the downloaded driver package on your computer. Then, select seuraava suorittaaksesi päivityksen.

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. Avaa Laitehallinta.

2. Laajenna Bluetooth: luokka.

3. Right-click the Bluetooth module and select Poista laite.

4. Valitse valintaruutu Yritä poistaa tämän laitteen ohjain ja valitse Uninstall.

5. Restart your computer. Windows 11 will automatically reinstall the Bluetooth driver at startup. If it doesn’t, re-open the Laitehallinta ja valitse Toiminta > Tarkista laitteiston muutokset.

Päivitä näytönohjaimet

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).

Päivitä 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. Avaa Käynnistä-valikon ja valitse Asetukset.

2. valita Windows Update on the Settings sidebar.

3. valita Tarkista päivitykset.

4. valita Lataa nyt asentaaksesi saatavilla olevat päivitykset.

Lisäksi valitse Lisäasetukset > Valinnaiset päivitykset and install any Microsoft-verified driver updates for the Bluetooth mouse, the Bluetooth module, and the graphics card.

Etsi haittaohjelmia

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

Poista nopea käynnistys

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. Avaa Aloita valikko, kirjoita Ohjauspaneelin, ja paina enter.

2. valita Laitteisto ja äänet.

3. Alla Virta-asetukset , valitse Valitse, mitä virtapainikkeiden.

4. valita Muuta asetuksia, jotka eivät ole käytettävissä.

5. Uncheck the box next to Kytke nopeaa käynnistystä (suositus) and select Save changes.

Mitä muuta voit tehdä?

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.
