I have an older soundbar that has worked great.  I have been using it with my laptop at work for speakers.  I had to disconnect it from my laptop and when I connected it back and turned it on it will not connect.  All it does is stay "ON" the display.  I've tried holding in the volume up/down and nothing.  I tried holding the power button in and nothing.  The remote will turn it on but will not turn it off.  I have to unplug it to turn it off.  Any ideas other than trash it and buy another one?
