How To Turn On Bluetooth On Windows 10

Tips
1

I’m trying to connect wireless headphones to my Windows 10 laptop, but I can’t find where to turn Bluetooth on. I’ve checked Settings and the Action Center, but the Bluetooth option doesn’t show up. Did I accidentally disable something, or is there another place I should look to enable Bluetooth on Windows 10?

When Bluetooth is missing in both Settings and Action Center, it is usually a driver or hardware issue, not a toggle issue.

Try this step by step:

  1. Check if Bluetooth hardware exists

    1. Press Windows key + X
    2. Click Device Manager
    3. Look for “Bluetooth” in the list
      • If you see “Bluetooth”
      Expand it and check for any yellow warning icons
      • If you do not see “Bluetooth”
      Look under “Network adapters” for anything with “Bluetooth” in the name

  2. If Bluetooth is disabled in Device Manager

    1. Under Bluetooth, right click your Bluetooth adapter
    2. If you see “Enable device”, click it
    3. If it already says “Disable device”, leave it

  3. If the driver is broken or missing

    1. In Device Manager, right click the Bluetooth adapter
    2. Click “Uninstall device”
    3. Check “Delete the driver software for this device” only if you have driver files ready from the laptop maker
    4. Reboot
    5. If Windows does not reinstall it, go to your laptop brand support site
      Example search: “Dell XPS 13 Bluetooth driver Windows 10”
    6. Download the Bluetooth driver for your exact model and Windows 10 version
    7. Install it, then restart

  4. Check Services

    1. Press Windows key + R
    2. Type services.msc and hit Enter
    3. Find “Bluetooth Support Service”
    4. Double click it
    5. Set Startup type to “Automatic”
    6. Click Start if Service status is Stopped
    7. Click OK
    8. Restart the PC

  5. Turn Bluetooth on once drivers work

    1. Press Windows key + I
    2. Go to Devices
    3. Click Bluetooth & other devices
    4. You should see a toggle for Bluetooth at the top
    5. Turn it On
    6. Click “Add Bluetooth or other device” and pair your headphones

  6. If Bluetooth still does not show up at all
    • Check your keyboard for a physical wireless or airplane mode key
    • Go to Settings > Network & Internet > Airplane mode
    Make sure Airplane mode is Off
    • Some older laptops do not have Bluetooth hardware
    Search your model specs on the manufacturer site and look for “Bluetooth 4.0” or similar in the wireless section

If your laptop model page says no Bluetooth, your only option is a USB Bluetooth dongle. They are cheap, plug into USB, and show up as a new Bluetooth adapter after driver install.

I had this happen on an HP, Bluetooth vanished after a Windows update. Driver reinstall from HP support center fixed it, then the toggle reappeared in Settings and the Action Center.

If Bluetooth isn’t showing in Settings or Action Center, you didn’t “turn it off” somewhere simple. It’s almost always one of three things: BIOS, Windows features, or power/radio controls. @reveurdenuit already covered drivers and services really well, so I’ll skip repeating that.

Try these in this order:

1. Make sure it’s not disabled in BIOS / UEFI

Sometimes Bluetooth is tied to the “Wireless” or “Internal Device” settings in BIOS.

  1. Shut down your laptop completely.
  2. Turn it on and spam the BIOS key (usually F2, Del, Esc, F10, or F12, depends on brand).
  3. Look for something like:
    • Wireless
    • Onboard Devices
    • Integrated Peripherals
  4. Make sure “Bluetooth” or “Wireless LAN & Bluetooth” is Enabled.
  5. Save & exit, boot into Windows, then check if Bluetooth shows up.

Surprisingly common after a BIOS reset or update.

2. Check if Windows has Bluetooth support components installed

This is rare, but on some stripped / corporate images:

  1. Press Windows + R, type:
    optionalfeatures.exe
    and hit Enter.
  2. In “Windows Features” look for anything Bluetooth related, like:
    • “Wireless Communication”
    • “Bluetooth Support” (wording varies)
  3. If you see it and it’s unchecked, check it, apply, reboot.

If nothing Bluetooth-related appears, that actually supports the idea that Windows doesn’t see any BT hardware at all.

3. Kill any “radio off” or airplane switches outside Windows

Even if Airplane mode in Windows is off, there might be:

  • A physical wireless switch on the side/front of the laptop.
  • A function key combo, like Fn + F2, Fn + F3, etc, sometimes with a tiny antenna icon.

Toggle that a few times, then recheck:

  • Settings > Devices > Bluetooth & other devices
  • Action Center > see if the Bluetooth tile appears

Sometimes those hardware toggles cut power to the Bluetooth chip so it vanishes from Device Manager entirely.

4. Check for “hidden” or unknown devices

If you didn’t see Bluetooth in Device Manager the normal way:

  1. Open Device Manager.
  2. Click View > Show hidden devices.
  3. Look for:
    • A faded “Bluetooth” category
    • “Unknown device” under “Other devices” or “Network adapters” that appears only when BT should exist

If you see an “Unknown device” with a warning icon, that’s often the BT chip with no proper driver. That’s your hint you’re on the right track and @reveurdenuit’s driver steps will matter.

5. Confirm your exact model actually ships with Bluetooth

Hate to say it, but I’ve seen this one too often: people assume all Wi‑Fi laptops have Bluetooth. Nope.

  • Look under the laptop, get the exact model number.
  • Go to the manufacturer’s support/specs page.
  • Check “Wireless” section for something like:
    • “Intel Dual Band Wireless‑AC + Bluetooth 4.2”
    • Or just “Bluetooth: Yes / No”

If the spec sheet says no Bluetooth, nothing you do in Windows will make a toggle appear. You’d need a cheap USB Bluetooth adapter.

6. When it is working, where the actual toggle lives

Once the hardware + drivers + services are behaving, the Bluetooth switch shows up in two spots:

  • Settings > Devices > Bluetooth & other devices
    There’s a simple On / Off toggle at the top.
  • Action Center (click the notification icon near the clock)
    You should see a tile named “Bluetooth.” Click it to toggle.

If those two locations both do not show Bluetooth, focus on: drivers, BIOS, radio / airplane hotkey, or the ugly possibility that your machine just doesn’t have BT hardware.

You almost certainly didn’t “accidentally disable” it from a normal menu; it’s either hidden deeper or Windows literally can’t see the chip.

Since you already checked Settings and Action Center and you’ve seen @reveurdenuit’s driver / service breakdown, I’d look at a few less obvious Windows-side angles that can completely hide Bluetooth without it being a BIOS or hardware kill issue.

1. Make sure Windows actually sees any Bluetooth stack

Even if there’s no “Bluetooth” section in Device Manager, Windows might still have remnants.

  1. Open Device Manager.
  2. Go to View > Devices by connection.
  3. Expand entries under:
    • ACPI x64-based PC
    • Microsoft ACPI-Compliant System
    • PCIe / USB controller branches
  4. Look for anything that sounds like:
    • “Bluetooth Radio”
    • “Wireless Module”
    • “Intel Wireless Bluetooth”
    • “Qualcomm QCA… Bluetooth”

If you see a device with a yellow exclamation, that is very likely the Bluetooth radio with a broken driver. In that case, uninstall it (right click > Uninstall device, check “Delete the driver software” if available), reboot, then install the vendor’s latest Bluetooth driver manually. This can resurrect the toggle even when the regular Bluetooth category never shows.

I slightly disagree with the idea that “no Bluetooth in Device Manager always means Windows can’t see the chip at all.” Sometimes it is just buried behind a composite USB device entry.

2. Check “Network adapters” and “USB controllers” for combo cards

A lot of laptops have Wi Fi + Bluetooth on one card. If Wi Fi works but Bluetooth is gone:

  • In Device Manager, expand Network adapters.
  • If your Wi Fi card is Intel / Realtek, right click it and check Properties > Details > Hardware Ids.
  • Search that hardware ID on the manufacturer’s site: many of those cards include Bluetooth even if Windows is not exposing it.

If specs say the card includes BT, but you only see Wi Fi in Device Manager, it often means the Bluetooth interface on that same chip is disabled by driver or power management, not necessarily BIOS.

3. Disable fast startup and do a true cold boot

Windows 10’s Fast Startup can keep a broken radio state “stuck.”

  1. Go to Control Panel > Power Options > Choose what the power buttons do.
  2. Click Change settings that are currently unavailable.
  3. Uncheck Turn on fast startup (recommended).
  4. Shut down completely, wait 10–15 seconds, then power on again.

After this, re check Device Manager and Settings. This actually fixes missing radios more often than you’d expect.

4. Check Group Policy & registry for disabled Bluetooth

On some corporate images Bluetooth is intentionally blocked, which can make it vanish from the UI.

  1. Press Win + R, type gpedit.msc and Enter.
  2. Go to Computer Configuration > Administrative Templates > Network > Bluetooth (if present).
  3. Look for policies like:
    • “Turn off the Bluetooth radio”
    • “Do not allow Bluetooth”
      Set anything like that to Not Configured or Disabled.

If you do not have Group Policy Editor (Home edition):

  1. Press Win + R, type regedit.
  2. Navigate to:
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\
  3. Look for a Bluetooth key.
    • If you see entries like DisableRadio or DisableServices set to 1, set them to 0 or delete that key, then reboot.

This is one angle @reveurdenuit did not emphasize as much, but it absolutely can hide the Bluetooth toggle and category on some business builds.

5. Check “Airplane mode” dependency and radio management

Sometimes Windows radio management is half broken:

  1. Go to Settings > Network & Internet > Airplane mode.
  2. If the Airplane mode switch is on, turn it off.
  3. If it is off, toggle it on, wait a few seconds, then turn it off again.

Then check Settings > Devices > Bluetooth & other devices again.
If Bluetooth briefly appears then disappears after a reboot, there might be a vendor radio manager app (HP Wireless Assistant, Dell QuickSet, Lenovo Vantage, etc.) forcing Bluetooth off. Open that app and ensure Bluetooth is toggled on there.

6. System File Check and DISM to fix broken Bluetooth components

If the OS components for Bluetooth are corrupted, drivers will install but the stack will not load correctly.

Run in an elevated Command Prompt:

sfc /scannow

After that finishes, run:

DISM /Online /Cleanup-Image /RestoreHealth

Reboot, then reinstall the OEM’s Bluetooth driver. This can restore “Bluetooth” in Settings when everything else looks fine.

7. When none of this works: accept missing hardware and use a USB adapter

If:

  • BIOS shows no Bluetooth setting,
  • No “Unknown device” or Bluetooth radio appears in Device Manager even with “Show hidden devices,”
  • Specs from the manufacturer clearly say no Bluetooth,

then the laptop simply does not provide it. In that case, a small USB Bluetooth adapter is the easiest fix.

Pros:

  • Cheap, often plug and play in Windows 10
  • Usually better range and newer Bluetooth versions than old built in chips
  • Avoids all the BIOS / corporate policy mess

Cons:

  • Occupies a USB port
  • Tiny dongles are easy to lose or accidentally break if left plugged in
  • Extra device to carry and manage

Despite @reveurdenuit covering the core hardware / driver checks really well, these extra OS level steps (Group Policy, fast startup, SFC/DISM, radio managers) often solve the “Bluetooth option completely gone” issue on Windows 10 when everything looks normal elsewhere.
