Bluetooth device loses connection

I certainly don't know nor understand why it is, but there seems to be some link in the fact that I left an old wired mouse plugged in after I used it to deal with the connection problem with the wireless trackpad and for now the Bluetooth vanishing connection seems to have stopped-or it has for now at any rate. Obviously this isn't a suitable solution, but for now, it seems to be working.

Thanks, but a lot of people have tried that and said that this did nothing helpful for them.

I don’t know if this is a solution that’ll work for everybody, but last night I installed fully charged batteries into my track pad when the Mac was off and then turned it on and voila the bluetooth dropout is gone. For how long or if it’s permanent I, of course, can’t say, but it’s working for now.
