Why won't my Bluetooth headphones or mouse connect to my PC?

You'll be able to: Reconnect an unresponsive Bluetooth accessory by turning Bluetooth off and on or re-pairing

The steps

1
Press WinA to open the Quick Settings panel near the clock. The Quick Settings panel opens showing quick toggles for Wi-Fi, Bluetooth, and volume.

Click the Bluetooth tile to turn it off, wait 5 seconds, then click it again to turn it back on. The Bluetooth icon dims to grey when turned off, then lights up blue and attempts to reconnect to your paired devices.
Why turn it off and on?
Toggling the Bluetooth radio clears temporary wireless connection handshakes between Windows and your accessory.
3
If it still won't connect, press WinI and click Bluetooth & devices. The Bluetooth & devices settings page opens, listing your paired accessories.

Click the three dots next to your device and choose Remove device, then click Add device to pair it fresh. Your computer searches for the device, pairs cleanly, and displays "Connected" beneath its name.
Tip
Before pairing again, ensure your headphones or mouse are in pairing mode (usually by holding its power or Bluetooth button until a blue or red light flashes rapidly).
