Answer 1

Hi Chandradip Raghuvanshi,
Welcome to Microsoft Q&A forum. I'm happy to help.

Sometimes the problem can easily be fixed by reboot your computer.

If it does, you might consider turn off Fast Startup following this article: How to turn on or off fast startup in Windows 10 and 11.

Follow these steps in order on Windows 11 to troubleshoot Bluetooth power-related failures:

1. Run the Bluetooth troubleshooter
   1. Open the Get Help app (search for “Get Help” from Start).
   2. Use the Bluetooth troubleshooter. It will automatically run diagnostics and attempt to fix Bluetooth problems.
   3. If prompted, apply any fixes it suggests.
2. Make sure Bluetooth is turned on and the device is in range
   1. Select Start > Settings > Bluetooth & devices.
   2. Ensure the Bluetooth toggle is turned On.
   3. Move the Bluetooth device close to the PC and make sure it is in pairing mode and has sufficient battery.
3. Turn Bluetooth off and back on
   1. In Settings > Bluetooth & devices, turn Bluetooth Off.
   2. Wait at least 10 seconds.
   3. Turn Bluetooth On again.
   4. Try pairing or reconnecting the device.
4. Remove and re-add the Bluetooth device
   1. Go to Start > Settings > Bluetooth & devices.
   2. Locate the problematic device, select More options (… ) > Remove device.
   3. Select Add device, choose Bluetooth, and select the device when it appears.
5. Check Windows Update
   1. Select Start > Settings > Windows Update.
   2. Select Check for updates and install all available updates.
   3. Restart the PC if requested, then test Bluetooth again.
6. Reinstall the Bluetooth adapter in Device Manager This helps if the driver or power management for the Bluetooth radio is corrupted.
   1. Select Search on the taskbar, type device manager, and open Device Manager.
   2. Expand Bluetooth.
   3. Right-click the Bluetooth adapter (may include the word “radio”) and select Uninstall device > Uninstall.
   4. Select Start > Power > Shut down.
   5. Wait a few seconds, then power the PC back on. Windows will try to reinstall the driver automatically.
   6. If it does not reinstall, open Device Manager, select Action > Scan for hardware changes.
7. Restart the PC
   1. Select Start > Power > Restart.
   2. After restart, test Bluetooth again.

If Bluetooth still reports a power failure after these steps, the issue is likely with the Bluetooth hardware or the PC’s power circuitry. In that case, contact the PC or motherboard manufacturer for hardware diagnostics and updated Bluetooth/power drivers.
