The pointer stops, you wiggle the mouse, and a few seconds later it wakes. Then it happens again. When a Windows 10 Bluetooth mouse keeps disconnecting, fine work judolbet88 becomes impossible.

Bluetooth mice save battery by sleeping when idle, and Windows saves power by switching off the Bluetooth radio when it can. The two sometimes go too far together.

Most disconnections are solved by changing a power setting, replacing batteries, or reducing interference.

What Might Be Causing It

Frequent disconnections usually come from these:

• Windows is allowed to power down the Bluetooth adapter.
• The mouse batteries are weak.
• Wi-Fi routers, USB 3.0 devices, or other wireless equipment are interfering.
• The Bluetooth driver is outdated or the pairing is corrupted.

USB 3.0 ports and hard drives are known to emit interference in the same frequency band as Bluetooth.

Start With These Basic Checks

Begin with the mouse and its surroundings.

1. Fit fresh batteries or fully charge the mouse.
2. Move the mouse closer to the PC and remove obstacles between them.
3. Unplug USB 3.0 drives and hubs temporarily to see whether the connection steadies.
4. Switch the mouse off and on, and restart the PC.
5. Check whether the mouse is also paired to another device nearby and disconnect it there.

If the mouse is steady with the USB devices removed, move those devices to ports further from the Bluetooth antenna.

Going a Step Further

Stop Windows from powering down Bluetooth.

1. Open Device Manager and expand Bluetooth.
2. Double-click the Bluetooth adapter, typically named Intel, Realtek, Qualcomm, or Broadcom, open the Power Management tab, and untick “Allow the computer to turn off this device to save power.”
3. Expand Human Interface Devices and Mice, and do the same for entries related to the Bluetooth mouse where the tab exists.
4. Open Settings > Devices > Bluetooth & other devices, remove the mouse, and pair it again.
5. Install the latest Bluetooth driver from the PC manufacturer.

Check the mouse manufacturer’s site too, as some models receive firmware updates that improve connection stability.

A Word of Caution

Keep a wired mouse or the laptop touchpad available before removing the pairing, so you can still navigate. Turning off power saving for Bluetooth has only a small effect on battery life. Avoid third-party Bluetooth “stack” replacements.

The Bottom Line

A Bluetooth mouse that drops out is usually being put to sleep or drowned out by interference. Fresh batteries, a clear path, and disabling adapter power saving fix most cases, and re-pairing with an updated driver deals with the others.
