I just received a Braven 625s wireless speaker for Christmas. After updating my Bluetooth driver on my machine (which now reads "ThinkPad Bluetooth 2.1 with Enhanced Data Rate II") and re-adding the device, I finally got it to work wirelessly. However the Bluetooth connection will not persist consistently.
It originally went off after about 30 minutes. I saw another post on this board that said to uncheck the “Allow the computer to turn off this device to save power” box under the Power Management tab of the Bluetooth device in Device Manager, so I did and that allowed the speaker to work for about an hour before it went silent again. It remained silent for about 10-15 minutes before the sound came back on. The sound remained on for about an hour, and then went off for about 20 minutes, then back on for 15 minutes, then went off and remained off for over 50 minutes before I manually disconnected the Bluetooth connection.
During the other times of silence, I am not manually doing anything with the connection or the speakers- the speakers remain on and the Bluetooth connection remains Connected. Even in the Playback Devices section, I could see my Bluetooth device look like it was working (the green bars would bounce up and down as if they were playing the music that was still “playing” off of my Lenovo), but no sound was coming out of the speaker.
Can someone help on why this is happening? I also saw another post that their Lenovo had a loose Bluetooth slot in their motherboard. Could this be it, or what other causes are there for this behavior?

What is the machine type and model of your ThinkPad, and what is your operating system? Also, when the event described in your post happened, were you using the computer actively, or just something like playing music or watching a film? And what version is your Bluetooth driver?
My first recommendation would be to make sure that your BIOS is updated, as an older BIOS can sometimes be responsible for odd issues. You can find the latest BIOS for your system here. Just select your machine type and find the driver associated with your operating system.
Best of luck, and let me know how it goes
