The fastest way to turn on Bluetooth
On Windows, open the Settings app by pressing the Windows key and typing "Settings," then select Bluetooth & devices from the left menu. Toggle the Bluetooth switch to On. On Mac, click the Apple menu in the top-left corner, select System Settings, then click Bluetooth in the sidebar and make sure it shows On.
If you see a Bluetooth icon in your system tray (Windows) or menu bar (Mac), you can also click it directly and select Turn on Bluetooth from the dropdown menu. This is the quickest route if the icon is already visible on your screen.
Key Takeaways
- Windows users open Settings, go to Bluetooth & devices, and toggle Bluetooth to On.
- Mac users open System Settings, click Bluetooth in the sidebar, and confirm it shows On.
- If your computer has a Bluetooth icon in the system tray or menu bar, you can click it directly to turn Bluetooth on without opening Settings.
- Some laptops have a physical Bluetooth button or keyboard shortcut (often Fn + a key with a Bluetooth symbol) that turns Bluetooth on when ready.
- After turning on Bluetooth, your computer will search for nearby devices and display them in a list so you can connect.
Finding the Bluetooth icon on Windows
The Bluetooth icon on Windows usually sits in the bottom-right corner of your screen, in the system tray next to the clock and volume controls. It looks like a small "B" made of two triangles. If you don't see it, your computer may not have Bluetooth hardware, or the icon may be hidden.
To unhide the Bluetooth icon, right-click the system tray area and look for an option to show hidden icons. On some Windows versions, you can also swipe in from the right edge of the screen to open the Action Center, where Bluetooth appears as a tile you can tap to turn on.
Finding Bluetooth on Mac
On Mac, the Bluetooth icon appears in the menu bar at the top-right of the screen, next to the Wi-Fi and battery icons. It looks like a small "B" made of dots. Click it to see a dropdown menu showing nearby Bluetooth devices and an option to turn Bluetooth on or off.
If you don't see the Bluetooth icon in your menu bar, open System Settings, click Bluetooth, and look for a checkbox that says Show Bluetooth in menu bar. Checking this box will make the icon appear so you can access it quickly in the future.
Using a physical Bluetooth button or keyboard shortcut
Many laptops have a dedicated Bluetooth button or a keyboard shortcut to turn Bluetooth on and off without opening any menus. On Windows laptops, this is often the Fn key held down while pressing a key with a Bluetooth symbol (usually a small "B" or antenna icon). On Mac laptops, you may find a similar Fn + key combination, though most Macs rely on the menu bar icon instead.
Check your laptop's manual or look at your keyboard to see if any keys have a Bluetooth symbol printed on them. If you find one, hold Fn and press that key to toggle Bluetooth on. This method is faster than opening Settings and useful if you turn Bluetooth on and off frequently.
What to do if Bluetooth doesn't appear in Settings
If Bluetooth is not listed in your Settings app, your computer may not have Bluetooth hardware built in. Older desktop computers and some budget laptops do not include Bluetooth. You can add Bluetooth to a desktop computer by plugging in a USB Bluetooth adapter, which costs between $10 and $30 and works with both Windows and Mac.
If your laptop should have Bluetooth but it's missing from Settings, the driver may need to be updated or reinstalled. On Windows, open Device Manager (right-click the Start button and select it), look for a Bluetooth entry, right-click it, and select Update driver. On Mac, restart your computer and check System Settings again—Bluetooth drivers update automatically.
Connecting a device after turning Bluetooth on
Once Bluetooth is on, your computer will begin scanning for nearby devices like headphones, speakers, mice, and keyboards. Open the Bluetooth settings again and look for a list of available devices. Click or tap the device you want to connect, and your computer will pair with it. Some devices require you to press a button on the device itself to make it discoverable.
After pairing, the device will usually connect automatically whenever it's turned on and in range. If a device doesn't connect, turn it off and back on, or remove it from your Bluetooth settings and pair it again from scratch.
Frequently Asked Questions
Why is my Bluetooth not turning on?
Check that Bluetooth is not disabled in your BIOS or UEFI settings (on Windows) or that it's not turned off in System Preferences (on Mac). Restart your computer and try again. If Bluetooth still doesn't appear, your computer may not have Bluetooth hardware, or the driver may need to be reinstalled.
Can I turn Bluetooth on and off from the keyboard?
Many laptops have a keyboard shortcut, usually Fn plus a key with a Bluetooth symbol. Check your keyboard or laptop manual to find the exact combination. Desktop computers typically do not have a keyboard shortcut and require you to use Settings or the system tray icon instead.
Does turning on Bluetooth drain my battery?
Bluetooth uses a small amount of power, but the drain is minimal unless you are actively connected to a device. Turning Bluetooth on but not pairing with anything uses very little battery. If battery life is a concern, turn Bluetooth off when you're not using wireless devices.
Why does my computer keep asking me to pair the same device?
This usually means the device was not fully paired or the pairing information was deleted. Go to your Bluetooth settings, find the device in the list, and select the option to remove or forget it. Then turn the device off and back on, and pair it again from scratch.
