With no warning, while I was replying to an email in Outlook, bluetooth just went away on my Windows 8.1 tablet (Wacom Cintiq Companion 2). Warband start own kingdom. [UPDATE] The problem went away after several hours and various steps the last of which are outlined in my answer below, but comes back quite often, seemingly at random, lasting anything from seconds to minutes to hours.
I've followed the steps on an MS support thread, and the Bluetooth Support service now claims to be running in services.msc (before, it was not running)..
..but the symptoms of my problem are still there, even after restarting the system. These are:
- Bluetooth keyboard lost connection, can't connect
- There used to be a Bluetooth icon in the desktop tray, now it's gone.
- If I open the 'metro-style' Bluetooth Settings page, it shows a blue cog for a few seconds, then either a blank white screen, or the generic 'Personal settings' home page
- If I open the desktop-style 'Change Bluetooth settings', the hardware section is completely empty:
..and if I change anything then click Okay, it says this:
An error occurred while Windows was saving your settings. The Bluetooth device might be unplugged.
This makes no sense because Bluetooth on this device is internal, it can't be unplugged.
The problem is exactly the same if I start up while charging, so it's not an energy saving issue. It stopped working while the device was unplugged, and the device was a normal temperature, so the internal Bluetooth adapter can't have been fried by a power surge or overheating.
Before just now, Bluetooth had worked fine for months - although in the last week or two, there has been a couple of times when the Bluetooth keyboard stopped working for about 10 seconds then started working again.
No updates have been applied recently, and no new software installed.
I can't find anything Bluetooth related in Device Manager to check the drivers (but to be honest I'm not 100% sure where to look). Plugins for pcsx 1.5. While trying to research this I found a MS answer that prompted me to look at what Bluetooth items I have in Control Panel, I'm not sure if this below is normal or not (I can't see 'Bluetooth devices'):
How could Bluetooth just disappear like this? What could have happened, and what can I do?
Update - this still happens, a lot. Bluetooth comes and goes seemingly randomly. Usually it sorts itself out after a few minutes, but sometimes it doesn't. No apparent pattern regarding when it happens, sometimes it's less than 20 minutes after booting up, sometimes it's after working for an entire day. When Bluetooth goes down like this, the Desktop settings report that it is working, but the COM Ports and Hardware tabs crash out:
Here's what happens if I try to restart the Bluetooth service in services.msc:
Error 1053: The service did not respond to the start or control request in a timely fashion.
Sometimes, after a long time of failing, the Metro-style Bluetooth settings screen appears looking like this, with a never-ending working indicator and no clue what it's trying to do.
Note that the 'metered connection' thing is almost certainly a red herring, it doesn't try to do any setup when I'm not on a metered connection. I'm also almost always on a metered connection and it doesn't usually complain.

Update - I don't think this below is a solution, I think it might have been coincidence that Bluetooth came back after I did this. Leaving it here as something that might sometimes work and an example of something I've tried.
As stated in the update to the question, bluetooth comes and goes. This seemed to help one time when it had gone for hours and nothing else seemed to work, but the problem repeats.

Bluetooth's back and my keyboard works again. I don't understand why it went away, or what the problem was, or how exactly it got fixed, so I'm keeping this issue open, but here are the steps that seemed to have an affect:

- I followed the linked MS answer above:
- Opened Services.msc` after searching for it from the Start screen
- Double-clicked the Bluetooth Support service, switched to
Log on
tab. - Changed

toNT AUTHORITYLocalService
- Started the service, rebooted. It claimed to be running, but nothing happened
- I later un-did the above..
- From

, clicked Browse, then Advanced, then Find now, and choseLocal service
- In the password field, I entered my standard user password
- I restarted the service and rebooted the computer
- From
- Then suddenly Bluetooth was back. The tray icon is back, I'm typing this on my bluetooth keyboard, the metro-style

takes me to actual bluetooth settings..
I don't know if it was the above that caused it to work, but this is what I did immediately before it worked, and it didn't work immediately before this, so maybe it'll help someone in a similar position.

Windows is very good on detecting Bluetooth adapters,but has the particularity that once the adapter is gone, everything Bluetoothjust disappears.
You case seems like the adapter has lost connection with the motherboard.But given that it is soldered-on, this is not very likely,so I believe that we have to assume a hardware problem.This is consistent with Bluetooth being restored by magic, and thendisappearing again by magic. For an intermittent problem, hardware is the mostlikely explanation.
If your tablet is still under warranty, use it. Don't wait for the warranty to elapse.

'Bluetooth Settings' is missing and not showing
When i go my Settings>Devices, here is what you'll see:
As you notice, the Bluetooth settings appears to be missing.
I've tried methods of online forums of the same problem, but none of those didn't worked.
Somebody told me to update the Bluetooth Driver in the Device Manager, but all drivers under the Bluetooth section seems to be updated.
This is actually all the drivers under my Bluetooth section. In all the video tutorials I've seen, they seem to have many drivers under the Bluetooth section than mine. But I think this has something to do with the disappearing of the Bluetooth settings. I guess?
I tried changing my Bluetooth Support Services in the Services Settings:
I clicked its Properties and I changed its Startup type from Manual to Automatic.
Then I clicked OK.
But.. the Bluetooth Settings is still now showing.I tried Troubleshooting it, but sad to say it didn't detect any problems relating to Bluetooth.
Somebody also told me to check in your Control Pannel > Programs > Programs and Features if you have Bluetooth installed.
Is the Bluetooth supposed to be there?
Are there any ways, fixes, methods to get my Bluetooth Settings back?
Please help me.
