Bluetooth Mouse or Keyboard Not Working in Windows

📅 23 July 2026 ⏱ 4 min read 🔧 PC Repair

It Was Working Yesterday — So What Happened?

Bluetooth devices drop off for all sorts of mundane reasons: a Windows update quietly reset a setting, the batteries died, or the PC simply "forgot" the device. The good news is that in the vast majority of cases you can fix this yourself in a few minutes, without touching a screwdriver. Work through the steps below in order — stop as soon as it works.

Step 1: Check the Basics First

It sounds obvious, but these catch a surprising number of problems:

Step 2: Make Sure Bluetooth Is Actually On in Windows

Windows updates occasionally turn Bluetooth off, or it may have been switched off by accident.

  1. Click the Start button, then open Settings (the cog icon).
  2. Go to Devices (Windows 10) or Bluetooth & devices (Windows 11).
  3. Check that the Bluetooth toggle is switched On.
  4. If it's already on, try toggling it off, waiting five seconds, then back on again.

Also check the quick-settings panel in the bottom-right corner of your screen (click the network/sound icons). There's a Bluetooth tile there too — make sure it's highlighted, not greyed out.

Step 3: Remove the Device and Pair It Again from Scratch

Sometimes Windows holds on to a corrupted connection record. Removing the device and re-pairing it clears that out.

  1. Go back into Settings → Bluetooth & devices.
  2. Find your mouse or keyboard in the list. Click the three dots (or "More options") next to it and choose Remove device.
  3. Put your device into pairing mode (hold the pairing button until the light flashes).
  4. Back in Windows, click Add device → Bluetooth and wait for your device to appear. Click it to pair.

Step 4: Restart the Bluetooth Support Service

Windows runs a background service that manages Bluetooth connections. If it has crashed or stalled, restarting it often fixes things without a full reboot.

  1. Press Windows key + R, type services.msc and press Enter.
  2. Scroll down to Bluetooth Support Service.
  3. Right-click it and choose Restart. If it shows as stopped, choose Start.
  4. While you're here, double-click it, set Startup type to Automatic, then click OK.

Now try pairing your device again from Step 3.

Step 5: Update or Roll Back the Bluetooth Driver

A faulty or outdated driver is the most common cause when all the above steps fail — and it's often triggered by a recent Windows Update.

  1. Right-click the Start button and choose Device Manager.
  2. Expand the Bluetooth section. You'll see your Bluetooth adapter listed (e.g. "Intel Wireless Bluetooth").
  3. Right-click it and choose Update driver → Search automatically for drivers.
  4. If that finds nothing, right-click again and choose Properties → Driver tab → Roll Back Driver (if available). This undoes the last driver update — very useful if the problem appeared right after a Windows Update.

Step 6: Try a USB Bluetooth Adapter as a Workaround

If your PC's built-in Bluetooth adapter has failed (especially common on older desktops), a small USB Bluetooth dongle costs around €8–€12 and plugs straight into any free USB port. Windows installs the driver automatically and your devices pair normally. It's a permanent, tidy fix — not just a temporary patch.

You'll find these in Carrefour, Leroy Merlin, or online. If you're unsure which one to buy, drop us a message — we're happy to advise.

When to Bring It In

If you've worked through every step above and the Bluetooth adapter still doesn't show up in Device Manager at all, the hardware itself may have failed — either the adapter on the motherboard or (on a laptop) a loose internal antenna cable. That's worth a professional look. We're based in Pinar de Campoverde and can usually diagnose it the same day.

It's also worth checking our guide on 5 warning signs your laptop needs a repair — a completely dead Bluetooth adapter can sometimes be an early indicator of wider hardware issues.

Most Bluetooth problems on Windows are software, not hardware. Work through the steps and you'll almost certainly be clicking away again within the hour.

FAQ

Why did my Bluetooth mouse stop working after a Windows update?

Windows updates sometimes overwrite or corrupt the Bluetooth driver. Go to Device Manager, find your Bluetooth adapter, and use 'Roll Back Driver' to undo the last driver change. If that option is greyed out, try 'Update driver' to fetch a fresh copy instead.

My Bluetooth is turned on but my mouse or keyboard won't appear in the list — why?

The device probably isn't in pairing mode. Look for a small button labelled 'Connect' or showing the Bluetooth symbol on the bottom or back of the device, and hold it until the indicator light flashes rapidly. Then go to Settings → Bluetooth & devices → Add device.

Can I use a Bluetooth mouse on a desktop PC that doesn't have built-in Bluetooth?

Absolutely. Buy a small USB Bluetooth adapter (dongle) for around €8–€12, plug it into any free USB port, and Windows will install the driver automatically. Your mouse or keyboard will then pair normally.

My Bluetooth adapter doesn't show up in Device Manager at all — is the PC broken?

Not necessarily broken, but it does need a closer look. On a desktop, the Bluetooth chip may have failed or a USB header connection may be loose. On a laptop, the antenna cable can come detached. Bring it in and we can diagnose it quickly, usually the same day.
