Windows 10: My computer suddenly can't detect my Bluetooth device and says it's disconnected. After...

I don't know what happened, but after starting my laptop this morning, my Bluetooth device isn't connected. After checking Bluetooth, it says no Bluetooth hardware detected on this device. But it does show up in the hidden devices in my device manager. After trying the deinstall reinstall, I didn't automatically reinstall after restarting. So I am absolutely lost.

Device Manager Un-Hiding Hidden Devices

When you connect a plug and play device, Windows Plug and Play manager detects it, finds and installs the driver. Device Manager lists the device with a solid icon.

The driver is only removed when you uninstall the device, not simply by disconnecting the device. When the device is disconnected, its driver is still installed. By default, Device Manager only displays connected devices. When you show hidden devices, note the Bluetooth icon you see is semi-transparent (not opaque). That indicates a "non-present" device. Sometimes also called a "ghost" device. The driver is still installed but the device is not currently detected (i.e. not connected).

Device can be disconnected when

• Device unplugged (e.g. removing a USB device)
• Turning a device OFF
• Disabling the device in BIOS (then windows won't detect it) or
• Device failure

So

• Check BIOS as suggested
• Check board connections
• Can b/t be turned off by a switch? or keyboard combination?

Also possible the b/t h/w failed

Windows can't detect bluetooth headphones

Hi,

I also had the same issue, it was quite irritating. The audio technica bluetooth device was detected by iphone and samsung phones but when I search with my laptop ( windows 10) it was not discoverable. The device was not showing in the bluetooth list of
discoverable devices. Pressed the headphone switch for long period but the laptop couldnot detect it. Did all the setting changes, changed all the options and updated all the drivers but still it was not detected.

I read somewhere that bluetooth uses something which is common with the wifi so I made sure that the wifi was enabled, airplane made was off. Next disconnected the laptop from the internet wifi connection. Once the laptop wifi was disconnected, it search
the bluetooth headset under 'Bluetooth & other device' and the device was listed. Previously when the laptop wifi was connected to the router, the bluetooth headset was not detected but after disconnecting from the router it was detected.

Steps:

1. Airplane mode: OFF

2. Wifi ON but not connected to any device

3. bluetooth ON

4. Search for the device

Hope this helps!!
