ພະຍາຍາມແກ້ໄຂດ່ວນເຫຼົ່ານີ້ກ່ອນ

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.

  • Restart ຄອມພິວເຕີຂອງທ່ານ: Usually, restarting your computer is all it takes to resolve problems in Windows. Save your work and select ເລີ່ມຕົ້ນ > ພະລັງງານ > ເລີ່ມ​ຕົ້ນ​ໃຫມ່ 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 ພະລັງງານ switch on the Bluetooth mouse and set it to off, ຫຼັງຈາກນັ້ນ 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.
  • ຕື່ມຂໍ້ມູນໃສ່ຫນູຂອງທ່ານ: 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.

ດໍາເນີນການແກ້ໄຂບັນຫາ 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. ເປີດ ເລີ່ມຕົ້ນ ເມນູແລະເລືອກເອົາ ການຕັ້ງຄ່າ.

2. ເລື່ອນລົງໄດ້ ລະບົບ settings and select the option labeled ແກ້ໄຂບັນຫາ.

3 ເລືອກເອົາ ການແກ້ໄຂບັນຫາອື່ນໆ.

4. ເລື່ອນລົງແລະເລືອກເອົາ ການດໍາເນີນງານ ປຸ່ມຢູ່ຕໍ່ໄປ Bluetooth. 

Install Support Software & Drivers

Bluetooth pointing devices work best with additional support software and mouse drivers—ຕົວເລືອກ 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 ກວດສອບການອັບເດດ 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.

ກົດຂວາໃສ່ປຸ່ມ ເລີ່ມຕົ້ນ ປຸ່ມແລະເລືອກເອົາ ຕົວ​ຈັດ​ການ​ອຸ​ປະ​ກອນ.

2. ຂະຫຍາຍ Bluetooth category, right-click the Bluetooth module—e.g., Intel(R) Wireless Bluetooth(R)— ແລະ​ເລືອກ​ເອົາ​ ອະສັງຫາ.

3. ປ່ຽນໄປທີ່ ການຄຸ້ມຄອງພະລັງງານ ແຖບແລະຍົກເລີກການເລືອກກ່ອງທີ່ຢູ່ຂ້າງ Allow the computer to turn off the device to save power. ຈາກນັ້ນ, ເລືອກ OK.

If that fails to resolve the issue, expand the ອຸປະກອນໂຕ້ຕອບຂອງມະນຸດ category (further down the Device Manager) and open the ອະສັງຫາ pane for Bluetooth Low Energy GATT compliant HID. ຫຼັງ​ຈາກ​ນັ້ນ​, ສະ​ຫຼັບ​ກັບ​ ການຄຸ້ມຄອງພະລັງງານ 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 ກ່ອນທີ່ຈະດໍາເນີນການ.

1 ກົດປຸ່ມ Windows + R to open the Run box. Then, type regedit ແລະກົດ ກະລຸນາໃສ່.

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

HKEY_LOCAL_MACHINE > SYSTEM > ກະແສໄຟຟ້າ > enum > USB

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

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

  • DeviceSelectiveSuspended
  • SelectiveSuspendEnabled
  • SelectiveSuspendSupported

ຫມາຍ​ເຫດ​: If any of the keys above appear missing, right-click a vacant area and select ໃຫມ່ > ມູນຄ່າ 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. ເປີດ ເລີ່ມຕົ້ນ ເມນູ ແລະເລືອກເອົາ ການຕັ້ງຄ່າ.

2. Select the category labeled ພະລັງງານ & ແບດເຕີຣີ.

3. ເປີດເມນູເລື່ອນລົງຂ້າງຖັດໄປ ຮູບແບບພະລັງງານ ແລະເລືອກເອົາ ຜົນງານທີ່ດີທີ່ສຸດ.

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. ເປີດ ເມນູເລີ່ມຕົ້ນ ແລະເລືອກເອົາ ການຕັ້ງຄ່າ.

2 ເລືອກເອົາ Bluetooth & ອຸປະກອນຕ່າງໆ on the Settings sidebar.

4 ເລືອກເອົາ ເພີ່ມອຸປະກອນ.

5 ເລືອກເອົາ 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. ເປີດ ຕົວ​ຈັດ​ການ​ອຸ​ປະ​ກອນ.

2. ຂະຫຍາຍ Bluetooth ຫມວດຫມູ່

3. Right-click the Bluetooth module and select ອັບເດດໄດເວີ.

4 ເລືອກເອົາ Browser my computer for drivers.

5 ເລືອກເອົາ ເອີ້ນເບິ່ງ and locate the downloaded driver package on your computer. Then, select ຖັດໄປ ເພື່ອປະຕິບັດການປັບປຸງ.

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. ເປີດ ຕົວ​ຈັດ​ການ​ອຸ​ປະ​ກອນ.

2. ຂະຫຍາຍ Bluetooth ຫມວດຫມູ່

5. Restart your computer. Windows 11 will automatically reinstall the Bluetooth driver at startup. If it doesn’t, re-open the ຕົວ​ຈັດ​ການ​ອຸ​ປະ​ກອນ ແລະເລືອກເອົາ ການປະຕິບັດ > ສະແກນສໍາລັບການປ່ຽນແປງຮາດແວ.

ປັບປຸງໄດເວີກາຟິກ

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).

ອັບເດດ 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. ເປີດ ເມນູເລີ່ມຕົ້ນ ແລະເລືອກເອົາ ການຕັ້ງຄ່າ.

2 ເລືອກເອົາ Windows Update on the Settings sidebar.

3 ເລືອກເອົາ ກວດສອບການປັບປຸງ.

4 ເລືອກເອົາ ດາວ​ໂຫຼດ​ດຽວ​ນີ້ ເພື່ອຕິດຕັ້ງການອັບເດດທີ່ມີຢູ່.

Additionally, select ຕົວເລືອກຂັ້ນສູງ > ການປັບປຸງທາງເລືອກ and install any Microsoft-verified driver updates for the Bluetooth mouse, the Bluetooth module, and the graphics card.

ສະແກນ Malware

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-ເຊັ່ນ​ວ່າ Malwarebytes—to thoroughly scan your PC for malware.

Disable Fast Startup

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. ເປີດ ເລີ່ມຕົ້ນ ເມນູ, ພິມ ກະດານການຄວບຄຸມ, ແລະກົດ ກະລຸນາໃສ່.

2 ເລືອກເອົາ ຮາດແວແລະສຽງ.

3 ພາຍ​ໃຕ້​ການ Power Options ພາກ, ເລືອກ ເລືອກສິ່ງທີ່ປຸ່ມພະລັງງານເຮັດ.

4 ເລືອກເອົາ ປ່ຽນການຕັ້ງຄ່າທີ່ບໍ່ມີຢູ່ໃນປະຈຸບັນ.

5. ປົດເລືອກກ່ອງທີ່ຢູ່ຂ້າງ ເປີດໃຊ້ງານເລີ່ມຕົ້ນໄວ (ແນະ ນຳ) and select Save changes.

ເຈົ້າສາມາດເຮັດຫຍັງໄດ້ອີກ?

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.
