Windows 10: Device Does Not Have Bluetooth

Bluetooth stopped working last week on my desktop PC. It had been working fine prior to that except for one incident in the past. I have a Dell 8930 with Windows 10. The warranty expired 3 weeks ago. Basically, the PC does not recognize the Bluetooth device. I have run troubleshooter on Bluetooth and get the response, “Device does not have Bluetooth.” Bluetooth also does not show up when I click on the ^ for system tray icons.



This happened once in the past, maybe about 6 months ago. At that time, I was told not sure if it was by Dell or by the retailer where I bought the PC to turn off the PC, turn it back on and tap the F2 key until I got to the Dell auto setup utility. Then hit the F2 key or “reset defaults”. That worked great then, but it did not work when I tried it this time. Once in the utility, hitting the F2 key seemed to do nothing and the option to “load defaults” did not fix the Bluetooth problem--"reset defaults" was not an option.



In Services, Bluetooth Support Service is “Running”. I changed it from manual to automatic.



In Settings, Bluetooth & other devices, there is no on/off slider and “Bluetooth is turned off” is the comment for the few enabled devices listed I use the PC manly for my Fitbit Charge 3. The only option is to remove the device. I have not tried that yet.



In Device Manager, normal view, Bluetooth is not listed separately. If I select show hidden devices, Bluetooth is there, but all the items listed under it seem grayed out/pale, and none of them are a Bluetooth adapter. There is also now a grayed-out Bluetooth device listed under Network Adapters, and a couple grayed out items under Other Devices. None are listed as Bluetooth adapters. I have clicked on Update Driver for all the listed sub items. I still get “Device does not have Bluetooth”.



I have downloaded and installed the Bluetooth driver for this PC from Dell.



In CMD I have run sfc /scannow, DISM /online /clean-upImage /scanhealth and Restorehealth with no problems found or restore completed successfully.



Windows has been updated.



Any thoughts on what the problem might be and what I might be able to do to “fit it”?

Bluetooth Technology Gets Faster With Bluetooth 3.0

From its annual All Hands Meeting in Tokyo this week, the Bluetooth SIG formally adopted Bluetooth Core Specification Version 3.0 + High Speed (HS), or Bluetooth 3.0. This latest iteration of the popular short-range wireless technology fulfills the consumers' need for speed while providing the same wireless Bluetooth experience – faster. Manufacturers of consumer electronics and home entertainment devices can now build their products to send large amounts of video, music and photos between devices wirelessly at speeds consumers expect.
Bluetooth 3.0 gets its speed from the 802.11 radio protocol. The inclusion of the 802.11 Protocol Adaptation Layer (PAL) provides increased throughput of data transfers at the approximate rate of 24 Mbps. In addition, mobile devices including Bluetooth 3.0 + HS will realize increased power savings due to enhanced power control built in.


"Like Ricky Bobby in Talladega Nights, this latest version was 'born to go fast,' said Mike's Blog, Ph.D., executive director of the Bluetooth SIG. "Utilizing the 802.11 radio was a natural choice as it provides efficiencies for both our members and consumers – members get more function out of the two radios they are already including in devices, and consumers with Bluetooth 3.0 + HS products will get faster exchange of information without changing how they connect. We are excited to expand the possibilities of the PAN."

This newest version of Bluetooth technology builds on the inherent qualities of the current 2.1 + EDR version, including Simple Secure Pairing and built-in, automatic security. And as with all versions of theBluetooth specification, v3.0 + HS provides developers, manufacturers and consumers with the benefit of backwards compatibility, enabling both the expansion and enhancement of this technology with every new specification release. Once products reach the market, the easiest way for consumers to learn which devices are compatible with other Bluetooth enabled devices is to visit the Bluetooth Gadget Guide.

Applications
With the availability of Bluetooth version 3.0 + HS, consumers can expect to move large data files of videos, music and photos between their own devices and the trusted devices of others, without the need for cables and wires. Some applications consumers will experience include:

• Wirelessly bulk synchronize music libraries between PC and music player or phone
• Bulk download photos to a printer or PC
• Send video files from camera or phone to computer or television

Availability

The Bluetooth SIG's formal adoption of the specification is only the first step in the product lifecycle. News out today from wireless chip manufacturers and Bluetooth SIG member companies Atheros, Broadcom and CSR shows the second step – getting silicon solutions to device manufacturers – is already underway. End products for consumers are expected to be in the market in 9 to 12 months.

Technical Specifications
This new specification release includes several major enhancements (learn more here - page requires member login):

• Generic Alternate MAC/PHY (AMP)
• 802.11 Protocol Adaptation Layer (PAL)
• Generic Test Methodology
• Enhanced Power Control
• Unicast Connectionless Data

Bluetooth device is shown as not present.

Hello Dominika,

Thank you for getting back to us. Since the issue still persists after following the steps on the article above, we'd like to know more. Kindly answer the following questions:

• Did you checked whether the Bluetooth device is listed under hidden devices in Device manager?
• What is the make and model of your Bluetooth device?
• Can you tell us the specific bluetooth devices that you're using on your Windows 10?
• Have you checked whether the Bluetooth driver is listed under installed programs under Programs and features?
  

Meanwhile, we suggest that you check if the Bluetooth services is enabled by following the steps below:

• Press Windows + R keys on the keyboard, type services.msc and press OK.
  
• Right click on Bluetooth Support service and select
  Restart.
  
• Right click on Bluetooth support service and select Properties
  and check if the startup type is Automatic.

We'll be waiting for your response.

 

No bluetooth after system restore

Thank you for your reply.

I mean I have used a Windows system restore point. I tried restoring bluetooth with commands in CMD (sfc/scannow; DISM /Online.....) and by updating and uninstalling devices in the device manager. Update did not work. Uninstalling bluetooth devices made Bluetooth disappear out of the hidden devices list.
All my steps I took worked but did not change anything in my bluetooth device list.

I am using the bluetooth of my mainboard. MSI Z370M Gaming Pro AC
My guess would be, that disabling the bluetooth network adapter before using a system restore point, disabled Bluetooth after using the system restore point.

In the device manager I get this message in the USB Device list for a unknown USB Device:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.
