Title:
dell inspiron 3521 laptop bluetooth does not connect to any device
Status in gnome-bluetooth package in Ubuntu:
New
Bug description:
With my Dell inspirion laptop i noticed some strange behaviour:
When i turn on my laptop and start ubuntu 14.04 (also experienced this with
12.04 and previous versions)
My Bluetooth never could connect to any device.
But when i first turn on my laptop in windows 7 (i have a dualboot)
then close Windows 7 and restart (not shut off) but restart in Ubuntu 12.04
or 14.04 my bluetooth adapter works fine..
When i then again shut off and turn back on my laptop the problem persists...
