Folks:

I've got a problem with the bluetooth on my HP Elitebook 840 G10.

When I boot up the system, bluetooth works fine ... I'm just using it for my mouse at the moment.

After a while, I don't know how long, bluetooth stops working.

I've combed through syslog to see if I can find anything that might indicate what is going wrong, and this is what I've found...

This is what is logged when I try to activate bluetooth ...

Code:

I found this in syslog from late in the previous day...,.

This is how lshw shows the bluetooth radio...
