Bluetooth is a technology that allows us to send and receive files, music, or other data wirelessly between adjacent devices. But sometimes we experience problems when Bluetooth won't turn on or can't connect to other devices. What are the causes and solutions to this problem? Here's the review.
For Android/Smartphones
There are several reasons why Bluetooth may not be enabled on an Android device. Some common reasons include:
- Airplane Mode On
Make sure your device is not in airplane mode. When airplane mode is on, all wireless functions, including Bluetooth, are disabled. - Hardware Problems
Sometimes, problems with hardware components can cause Bluetooth to not be activated. This could be a problem with the Bluetooth antenna, Bluetooth chip, or other hardware part. If this is the cause, it may require repair by a technician. - Problematic Software
Sometimes, software running in the background can cause problems with Bluetooth. This could happen after a software update or due to a conflict with another application. A system update or device reset can sometimes fix this problem. - Problem with Bluetooth Application Cache and Data
The Bluetooth app cache and data may have been corrupted, which may cause problems when trying to enable Bluetooth. Clearing the Bluetooth app cache and data in the device app settings may help. - Low Battery
When your Android device's battery is low, some wireless functions such as Bluetooth may be automatically disabled to save power. Make sure your battery is sufficient to activate Bluetooth. - Software Error (Software)
Sometimes, errors in the operating system or software can cause problems with Bluetooth. A recent system update or system cleanup might help fix this problem.
To determine the exact cause, you can try the following steps:
- Restart your device.
- Check the Bluetooth settings to ensure that there are no restrictions or special modes enabled.
- Check for the latest system updates that may have been released for your device.
- If the problem persists, try to seek further assistance from your Android device service center or device manufacturer.
For Windows Desktop/Laptop
1. Bluetooth Adapter is Not Active
One of the reasons why Bluetooth won't turn on is that the Bluetooth adapter on the laptop or computer is not active. A Bluetooth adapter is hardware that is responsible for sending and receiving Bluetooth signals. If this adapter is not active, Bluetooth will not work.
Solution: Enable the Bluetooth Adapter
To activate the Bluetooth adapter, we can do it via the Device Manager menu in Windows. Here are the steps:
- Open Device Manager by typing "Device Manager" in the Windows search field.
- Look for the Bluetooth section and right click on the existing Bluetooth adapter.
- Select Enable Device to activate the Bluetooth adapter.
2. Bluetooth Discoverable Settings Are Inappropriate
Another cause of Bluetooth not turning on is that the discoverable or Bluetooth discovery settings are not appropriate. This setting functions to ensure that our device can be seen by other devices when Bluetooth is active. If these settings are not appropriate, then our device will not be detected by other devices.
Solution: Set Discoverable Bluetooth Settings
To set discoverable Bluetooth settings, we can do this via the Control Panel menu in Windows. Here are the steps:
- Open Control Panel by typing "Control Panel" in the Windows search field.
- Open the Devices and Printers menu.
- Right click on our laptop or computer icon and select Bluetooth Settings.
- Check the Allow Bluetooth devices to find this PC option and click OK.
3. Bluetooth service is not running
The next reason why Bluetooth won't turn on is that the Bluetooth service isn't running. Service is a setting intended for the program to be able to activate the Bluetooth adapter at any time when you want to use it. If this service is not running, then Bluetooth will not work.
Solution: Run Bluetooth Service
To run the Bluetooth service, we can do it via the Services menu in Windows. Here are the steps:
- Open Services by typing "Services" in the Windows search field.
- Look for a service called Bluetooth Support Service and right click on it.
- Select Start to run the service.
4. Bluetooth Drivers Are Not Latest
The next reason why Bluetooth won't turn on is that the driver or software that controls the Bluetooth adapter is not up to date. Drivers that are not up to date can cause compatibility issues or poor performance on the Bluetooth adapter.
Solution: Update Bluetooth Driver
To update the Bluetooth driver, we can do it via the Device Manager menu in Windows. Here are the steps:
- Open Device Manager by typing "Device Manager" in the Windows search field.
- Look for the Bluetooth section and right click on the existing Bluetooth adapter.
- Select Update Driver to update the driver.
5. Bluetooth Device Problem
The final cause of Bluetooth not turning on is that the Bluetooth device we want to connect has a problem. Bluetooth devices can have problems because they are damaged, the battery is dead, the distance is too far, or interference from other devices.
Solution: Check Bluetooth Device
To check Bluetooth devices, we can do the following things:
- Make sure the Bluetooth device is in good condition and not damaged.
- Make sure the bluetooth device has sufficient battery power or is connected to a power source.
- Make sure the Bluetooth device is close to our laptop or computer.
- Make sure the Bluetooth device is not interfered with by other devices that use the same frequency, such as WiFi, microwave, or USB devices.
That's the article about why Bluetooth won't turn on along with the causes and solutions. Hopefully useful and good luck.
