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.

  • Restartovat váš počítač: Usually, restarting your computer is all it takes to resolve problems in Windows. Save your work and select Home > Power > Restart 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 pryč, pak 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.
  • Nabijte svou myš: 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.

Spusťte Poradce při potížích s Bluetooth

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

1. Otevři Home Menu a zvolte Nastavení.

2. Přejděte dolů Systém settings and select the option labeled Poradce při potížích.

3. vybrat Další nástroje pro odstraňování problémů.

Install Support Software & Drivers

Bluetooth pointing devices work best with additional support software and mouse drivers—Možnosti Logitech, 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 Zkontrolovat aktualizace 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. Klepněte pravým tlačítkem na ikonu Home a vyberte Device Manager.

2. Rozbalte Bluetooth category, right-click the Bluetooth module—e.g., Intel (R) Wireless Bluetooth (R)– a vyberte Nemovitosti.

3. Přepněte na Power Management kartu a zrušte zaškrtnutí políčka vedle Nechejte počítač z důvodu úspory energie vypnout zařízení. Poté vyberte OK.

If that fails to resolve the issue, expand the Human Interface Devices category (further down the Device Manager) and open the Nemovitosti pane for Bluetooth Low Energy GATT compliant HID. Poté přepněte na Power Management tab and clear the box next to Nechejte počítač z důvodu úspory energie vypnout zařízení.

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 před pokračováním.

1. lis Windows + R to open the Run box. Then, type regedit a stiskněte vstoupit.

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

HKEY_LOCAL_MACHINE > SYSTÉM > CurrentControlSet > Enum > USB

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

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

  • DeviceSelectiveSuspended
  • SelectiveSuspendEnabled
  • SelectiveSuspendSupported

Poznámka: If any of the keys above appear missing, right-click a vacant area and select Nový > DWORD (32-bit) Value. 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. Otevři Home menu a zvolte Nastavení.

2. Select the category labeled Napájení a baterie.

3. Otevřete rozevírací nabídku vedle režim Power a zvolte Nejlepší výkon.

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. Otevři V nabídce Start a zvolte Nastavení.

2. vybrat Bluetooth a zařízení on the Settings sidebar. 

3. Vybrat Moře icon (three dots) next to your Bluetooth mouse and select Odebrat zařízení > Ano.

4. vybrat Přidat zařízení.

5. vybrat 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. Otevři Device Manager.

2. Rozbalte Bluetooth kategorie.

3. Right-click the Bluetooth module and select Aktualizovat ovladač.

4. vybrat Prohledejte můj počítač pro ovladače.

5. vybrat Procházet and locate the downloaded driver package on your computer. Then, select další k provedení aktualizace.

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. Otevři Device Manager.

2. Rozbalte Bluetooth kategorie.

3. Right-click the Bluetooth module and select Odinstalujte zařízení.

4. Zaškrtněte políčko vedle Pokuste se odebrat ovladač pro toto zařízení a zvolte Odinstalovat.

5. Restart your computer. Windows 11 will automatically reinstall the Bluetooth driver at startup. If it doesn’t, re-open the Device Manager a zvolte Akce > Prohledávání změn hardwaru.

Aktualizujte grafické ovladače

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).

Aktualizujte systém 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. Otevři V nabídce Start a zvolte Nastavení.

2. vybrat Windows Update on the Settings sidebar.

3. vybrat Zkontrolovat aktualizace.

4. vybrat stáhnout nyní k instalaci dostupných aktualizací.

Additionally, select Pokročilé volby > Volitelné aktualizace and install any Microsoft-verified driver updates for the Bluetooth mouse, the Bluetooth module, and the graphics card.

Vyhledávání škodlivého softwaru

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-jako Malwarebytes—to thoroughly scan your PC for malware.

Zakázat rychlé spuštění

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. Otevři Home menu, typ řídicí panel, a stiskněte tlačítko vstoupit.

2. vybrat Hardware a zvuk.

3. Pod Možnosti napájení vyberte část Vyberte si, co Tlačítky dělat.

4. vybrat Změna nastavení, které jsou v současné době k dispozici.

5. Zrušte zaškrtnutí políčka vedle Zapněte rychlé spuštění (doporučeno) and select Save changes.

Co dalšího můžete dělat?

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.
