There could be several reasons why your laptop's Bluetooth is not working. Here are some things you can try:
Make sure Bluetooth is turned on: Check if your laptop has a physical Bluetooth switch or button and make sure it is turned on. You can also try turning on Bluetooth through the settings on your laptop.
Check if your laptop supports Bluetooth: Some older laptops may not have Bluetooth capabilities. Check your laptop’s specifications to confirm if it has Bluetooth.
Check if your Bluetooth device is compatible: Make sure that the device you are trying to connect to your laptop is compatible with Bluetooth and that it is turned on and in pairing mode.
Update drivers: Check if your laptop’s Bluetooth drivers are up to date. You can usually update your drivers through your laptop’s device manager.
Restart your laptop and device: Sometimes restarting your laptop and the Bluetooth device you are trying to connect can fix connectivity issues.
Disable conflicting apps: Some applications can interfere with Bluetooth connectivity. Try disabling any apps that might be conflicting with Bluetooth.
If none of these solutions work, there may be an issue with the Bluetooth hardware on your laptop. In this case, you may send your laptop to an authorised service centre if still under warranty or visit Esmond Service Centre if your laptop is out of warranty.
