If the keyboard works with another device but not with Windows 11, the issue is usually Bluetooth pairing or the Windows connection state.
- Make sure the keyboard is in pairing mode.
- For many Microsoft Bluetooth keyboards, press and hold the pair button for about 5 seconds until the LED starts flashing.
- On some models, turning the keyboard on puts it into pairing mode automatically. If not, hold the pair button until the light flashes.
- Pair it again in Windows 11.
- Go to Start > Settings > Bluetooth & devices > Add device > Bluetooth.
- Select the keyboard from the list.
- If Windows shows a Connect notification, select it and wait for setup to finish.
- If it was already paired before, remove it and pair it again.
- In Settings > Bluetooth & devices, remove the keyboard if it appears there.
- Then put the keyboard back into pairing mode and add it again.
- Confirm the PC supports Bluetooth and that Bluetooth is turned on.
- Windows devices need Bluetooth to pair Bluetooth keyboards.
- If the PC does not have built-in Bluetooth, a USB Bluetooth adapter is needed.
- Check basic hardware conditions.
- Since the batteries are new, also make sure the keyboard has power, there is no dirt blocking keys or sensors, and if it uses a USB receiver or hub, try reconnecting directly to the PC.
- If the keyboard still does not connect, test the wireless connection.
- If the device has a Reset button on the bottom, use it to disconnect and reconnect the wireless connection.
- For Bluetooth issues in Windows, also use the Windows Bluetooth troubleshooting guidance.
If the keyboard is a Microsoft model, the exact pairing method depends on the model:
- Microsoft Bluetooth Keyboard: hold the pair button on the bottom for 5 seconds until the LED flashes.
- Microsoft Designer Compact Keyboard: slide the switch on the bottom to turn it on; it should enter pairing mode automatically, or hold the pair button on the top left for 5 seconds until the LED flashes.
- Surface Keyboard: hold the pair button on the side until the LED above the Up arrow flashes, then complete pairing in Windows and enter the PIN if prompted.
