Why Using a Bluetooth adapter in Windows 8 does it randomly shut off?

I'm using a Toshiba C855-S7344 for which I needed to get a Bluetooth adapter in order to use my Bluetooth speakers. However after installing them I'm finding that the Bluetooth is randomly shutting off every few minutes. Now when I installed it all I did was add the device as with the adapter I could not find a way to connect it via the network connection. Is there something I am missing? Or since I am using an adapter do I just need to pair it thru add device? As the later seemed to work for a few days before I have had the problem of it randomly shutting down. I have checked and I do have the current driver installed and have also run the hardware utility with no fixes. I do not get any error messages it just shuts down and if I turn the speaker off and back on the bluetooth reconnects. If anyone could help I'd greatly appreciate it!

Bluetooth is a tricky connection sometimes and it sounds like the problem you are experiencing is a problem with either the adapter or the speaker.

Is the speaker running off of a battery or is it plugged in?

Hi Lora,

Can you try to turn off the power saving feature ("turn off this device to save power") of the bluetooth adapter from the Device Manager > Bluetooth and see if probem goes or not.



If it doesn't work, follow below steps as well:


If the Bluetooth entry in the device manager is missing when the issue occurs then it's possible that the bluetooth hardware might have gone faulty or Windows disconnected the device for some unknown reason (eg., IRQ errors)

In addition, the Bluetooth hardware is normally embedded on the Wireless Adapter (Wi-Fi + Bluetooth Combo card). When the bluetooth device fails, are you still able to use the wireless functionality?

Other things that you can try or check:

1. Open Control Panel (icon views) > Programs and Features and uninstall the Bluetooth Driver then reboot. After the restart, the bluetooth device should use an inbox driver. Try to pair a bluetooth device and observe.


I hope this helps.

Regards,
Lokesh

I kept getting the blue screen with Driver Power State Failure error message and then my computer would restart. I found your product and it did not happen any more. I just purchased an anti-virus (kaspersky) and now it is doing it again. It is so frustrating. My computer is only 6 months old. It is a Asus desktop.
