Thanks for the reply,, as for the Power Control Installation file no longer working which I do not know why like almost most of N9 applications. Each time I try to install this application it says not installing... As for for the repair I will see what I can do regarding this matter, My question is,, is there any terminal command to shut it down??
devel-su
/sbin/reboot
/sbin/shutdown -r 0
/sbin/shutdown -h 0
