powatool is an application wich enables you to edit the statusbar (the bar wich pops up when clicking on the clock with internet connection and bluetooth and other options). with this program you can delete some things wich you find unusefull, in my case the bluetooth thing.

there is though more to "powatool". for example you have the option to disable the popup when connecting the usb cable, and other different things. i went on disabling things not knowing what they were, and with that i disabled the popup by accident. in powatool its called: "usb status menu". checking this box will get the popup back.

altough if you dont use this app, there will probably be an underlying problem in your case, with which i cant help you. only one advise, try installing powatool via app manager en see if that fixes the problem

hope i could help
