Fix Bluetooth problems in Windows 10

लागू: Windows 10

If you’re trying to connect to a Bluetooth device and run into problems, here are some steps to try to get things working again.

Things to try first

1. Check your product information

If you’re setting up a new device and Bluetooth is missing, check the product specifications to make sure the device has Bluetooth capabilities. Some devices don’t have Bluetooth.

When Bluetooth doesn't work or the Bluetooth icon is missing

If Bluetooth isn't working after following the steps in the first section, you might be having one of these common problems:

  • The Bluetooth icon is missing or Bluetooth can't be turned on or off. 
  • Bluetooth doesn't work after installing an update for Windows 10.
  • Bluetooth doesn't work after upgrading to Windows 10 from Windows 8.1 or Windows 7.
  • Bluetooth doesn't appear in Device Manager, and there are no unknown devices listed.

If any of these scenarios sounds like the problem you're having, try following the steps below.

Run the Bluetooth troubleshooter

Select the Start button, then select Settings > Update & Security  > Troubleshoot . Under Find and fix other problems, select Bluetooth, and then select Run the troubleshooter and follow the instructions.

Troubleshoot problems with Bluetooth accessories

If you can turn on Bluetooth but are having problems pairing or using a Bluetooth accessory, see the instructions below, which can help you troubleshoot common problems with Bluetooth accessories.

You should also check your device manufacturer's website, especially if Bluetooth devices besides the one you're having problems with are working. The device manufacturer will likely have more detailed, product-specific information and troubleshooting steps. 
Keyboard, mouse, or pen
  • If you’re asked to enter a PIN to use your device, but you don’t know the PIN:
    • Check the device’s documentation for a pin, or look for one on the device itself.
    • Try typing 0000 or 1234.
  • If you’re asked to enter a PIN, but you don’t see a place to enter one on your PC’s screen, type 0000 on your Bluetooth keyboard and press Enter.
  • Try to remove the device, then pair it again. Your device might be paired, but not connected—Bluetooth keyboards, mice, and pens only connect when necessary.

    To remove a Bluetooth device, select the Start  button, then select Settings  > Devices  > Bluetooth & other devices . Select the Bluetooth device that’s paired but not working, then select Remove device > Yes. After that, pair the device again. For more info on pairing devices, see Connect a Bluetooth device.
