Hi @SatanNarch,

Make sure the system has the latest BIOS version.

Also, did you reinstall the Bluetooth driver already?

1.I already reinstalled all bluetooth drivers already. 

2. BIOS update has a problem since my battery is faulty, Insydeflash gives that message of make sure, your laptop is connected to battery and AC Adapter

3. I have tried the DOS Command solution of /forceit but it still doesn't work. 

4. I have extracted all contents in a folder in C:/BIOS and ran it... shows the NO ROM Error.

@SatanNarch,

Are any other BT devices working?

Yes my phone is working, my other phones are working, my files are shared well.

That speaker can be connected with other phones and my phone's bluetooth.

Just that speaker is not getting connected with my Alienware.

Then it should be related with a compatibility issue.

This same speaker use to work and worked for 4 months, suddenly it started showing this issue

@SatanNarch,

So maybe you can try a system restore back to a date where it was working.
