HP EliteBook 840 G10 Bluetooth Mouse Disconnecting Windows 11: Fix

If your Bluetooth mouse on your HP EliteBook 840 G10 keeps disconnecting and reconnecting every few minutes, you are dealing with a common driver or power management issue. This behavior is especially frustrating when the disconnections worsen on battery power. The good news is that this issue has several straightforward fixes involving driver updates and power settings.

Why HP EliteBook 840 G10 Bluetooth Mouse Is Disconnecting

Intel Bluetooth Driver Outdated or Conflicting

The HP EliteBook 840 G10 uses an Intel Bluetooth adapter that requires a current driver to maintain stable connections. If this driver is outdated, corrupted, or conflicts with Windows 11, your Bluetooth mouse will drop its connection repeatedly. You may notice that the mouse reconnects on its own briefly before disconnecting again shortly after.

Bluetooth Power Management Enabled

Windows 11 and many Bluetooth adapters have a power-saving feature that reduces Bluetooth activity when the laptop is on battery power to extend battery life. While this saves battery, it causes Bluetooth devices to disconnect frequently. Common signs that power management is the cause include:

• Disconnections happen mainly or exclusively on battery power
• Mouse works fine when the laptop is plugged in
• Mouse reconnects immediately when you move it or click a button
• Problem worsens the lower the battery percentage gets

Duplicate Bluetooth Entries in Device Manager

Sometimes Windows 11 creates duplicate Bluetooth device entries, or previous Bluetooth adapters remain in Device Manager even though they are no longer in use. These duplicates can conflict with the active Bluetooth connection, causing your mouse to drop. You might see multiple Bluetooth entries in Device Manager that slow down connection attempts.

How to Fix HP EliteBook 840 G10 Bluetooth Mouse Disconnecting

Step 1: Disable Bluetooth Power Management

Turning off power-saving features for Bluetooth is the fastest way to stop disconnections, especially on battery power:

1. Right-click the Start menu and select Device Manager.
2. Expand the Bluetooth section by clicking the arrow next to it.
3. Right-click your Intel Bluetooth adapter and select Properties.
4. Go to the Power Management tab.
5. Uncheck the option that says Allow the computer to turn off this device to save power.
6. Click Apply and OK.
7. Restart your computer and test your mouse.

This single step fixes the issue in many cases, especially if disconnections happen mainly on battery power.

Step 2: Update Intel Bluetooth Driver from HP Support

Visit the HP support website and search for your exact EliteBook 840 G10 model. Download the latest Intel Bluetooth driver for Windows 11. Right-click your Bluetooth device in Device Manager and select Update Driver. Choose Browse my computer for drivers and navigate to the folder where you saved the HP Bluetooth driver. Follow the installation prompts, restart your computer, and test your mouse connection after the restart. The latest driver from HP includes fixes for connection stability that improve performance significantly.

Step 3: Remove Duplicate Bluetooth Entries

If you see multiple Bluetooth adapters or entries in Device Manager, clean them up by right-clicking each duplicate or unused Bluetooth entry and selecting Uninstall Device. Leave only one Bluetooth adapter enabled. After removing duplicates, restart your computer and your mouse should connect more reliably. Also unpair and re-pair your mouse from Bluetooth Settings for a clean fresh connection.

Frequently Asked Questions

Will disabling Bluetooth power management drain my battery faster?

Disabling power management will use slightly more battery, but the impact is minimal for most users. A Bluetooth mouse uses very little power compared to your display or CPU. If battery life is critical, you can re-enable power management and instead manually restart your Bluetooth connection when you notice disconnections during longer sessions away from a charger.

Why do I have multiple Bluetooth entries in Device Manager?

Multiple entries happen when you pair with many devices, use different Bluetooth adapters over time, or when Windows fails to fully uninstall a driver. These extra entries do not hurt, but they can slow down your system. Removing unused entries and keeping only your current Intel Bluetooth adapter is a good practice for maintaining stable connections.

Should I unpair and re-pair my mouse after making these changes?

Yes. After making the driver and power management changes, remove your mouse from Bluetooth Settings and pair it again fresh. Go to Bluetooth Settings, find your mouse, click Remove Device, and then pair it again. This gives your EliteBook a clean connection and often resolves any lingering stability issues from the old pairing.

What if my Bluetooth still disconnects after these fixes?

Try these additional steps: toggle Bluetooth off and on in Settings to restart the adapter, move your mouse closer to the laptop, and check for USB device interference from wireless dongles plugged into nearby ports. If the issue started after a recent driver update, consider rolling back the Bluetooth driver in Device Manager to the previous version. Contact HP support if the problem continues after all these steps.

Conclusion

The HP EliteBook 840 G10 Bluetooth disconnection issue is usually caused by power management settings, outdated drivers, or duplicate Bluetooth entries. Start by disabling Bluetooth power management in Device Manager, update your Intel Bluetooth driver from HP support, and remove any duplicate Bluetooth adapters. Most users see stable Bluetooth connections after completing these three steps.
