    OK. Seems intermittent physical disconnection. Hopefully, dirty or loose connection and not a bad solder ball.

    Remove 11 screws from bottom cover and pry cover off with a credit card wedge starting from the hinge end. Remove tape from battery pack connector and pull it off the mainboard. Remove 2 screws holding battery. Remove battery. The look for the m.2 bt-wifi card. Unscrew it. It should pop up in its m.2 mainboard socket. If possible leave the antenna wires attached because their mini coax plugs are very fragile. Plug the card back in at an angle. Push it down but don't screw it down yet. Release. Pull the card out again. Repeat process a half-dozen of so times to help clean the contacts and pins in the mainboard socket. Then button it all back up.

    I should have read all of your instructions to the letter. I stupidly disconnected the pins. Now I have no chance of getting then to pop back in.

    I really appreciate all of your time and help Jack, I'll chalk this down to experience and start reading instructions in the future.

    I secured the plugs down with some tape. The WiFi strength indicator has all but dropped off, but it stays connected. I've unplugged it, walked around the house and it didn't lose connection once.

    Do you mean the antenna cable mini-coax plugs?

    Yes. The WiFi is great but Bluetooth either won't connect at all. Or keeps dropping out.

    Why not? Make sure the plug's center connector is straight, centered & slips into the center connector on the card. They're too loose with poor signal transfer if tape has to be used to hold them. Gently squeeze the outer ring of the plug or card receptacle with tweezers or your fingernail so they fit snuggly together

    I'll definitely give that a go Jack. Probably with the help of someone who's eyesight isn't like Mr Magoo's, and who also has fingers that don't resemble jumbo sausage. I'll let you know.

    Again, Thank you so much for all of your help.
