Hi Nicholas, I have had a Dell 870 computer with AC 411 since 12-23-13. I have spent many, many hours with Dell support, and they sent me me 2 more AC 411 speakers. In fact, until a few moments ago I had lost the ability to pair; it has paired and worked for several days and then I lost it and could not pair until I just read your email. Could you share how you discovered to hold down button for 40150 seconds, and it works?  Thanks, John 
Good day.  My tablet running Windows 8 is not detecting my new AC 411 Bluetooth speakers.  Would appreciate any help please.
