  • 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.

Rhedeg Datryswr Problemau 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. Agorwch y dechrau ddewislen a dewiswch Gosodiadau.

2. Sgroliwch i lawr y system settings and select the option labeled Troubleshoot.

3. Dewiswch Datryswyr eraill.

4. Sgroliwch i lawr a dewiswch y Run botwm nesaf Bluetooth. 

Install Support Software & Drivers

Bluetooth pointing devices work best with additional support software and mouse drivers—Dewisiadau Logitech, Synapse Razer, 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 Gwiriwch am y Diweddariadau 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. De-gliciwch y dechrau botwm a dewiswch Rheolwr Dyfais.

2. Ehangu'r Bluetooth category, right-click the Bluetooth module—e.g., Intel(R) Wireless Bluetooth(R)—a dewiswch Eiddo.

Yna, newid i'r Rheoli pŵer 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 cyn symud ymlaen.

1. Gwasgwch ffenestri + R to open the Run box. Then, type regedit ac yn y wasg Rhowch.

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

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

  • DeviceSelectiveSuspended
  • SelectiveSuspendEnabled
  • SelectiveSuspendSupported

Nodyn: If any of the keys above appear missing, right-click a vacant area and select Nghastell Newydd Emlyn > Gwerth DWORD (32-bit). 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. Agorwch y dechrau fwydlen a dewis Gosodiadau.

2. Select the category labeled Pwer a batri.

4. Dewiswch Ychwanegwch ddyfais.

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

1. Agorwch y Rheolwr Dyfais.

2. Ehangu'r Bluetooth categori.

3. Right-click the Bluetooth module and select Dyfais dadstystio.

4. Gwiriwch y blwch wrth ymyl Ceisiwch dynnu'r gyrrwr ar gyfer y ddyfais hon a dewis Uninstall.

Diweddaru Gyrwyr Graffeg

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).

Diweddarwch 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.

Additionally, select Dewisiadau mwy cymhleth > Diweddariadau dewisol and install any Microsoft-verified driver updates for the Bluetooth mouse, the Bluetooth module, and the graphics card.

Sganiwch am Malware

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

Analluoga Cyflym Cyflym

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. Agorwch y dechrau menu, math Panel Rheoli, a'r wasg Rhowch.

Beth Arall Allwch Chi Ei Wneud?

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.
