Hi,
Since i pressed the fn + f3 button on windows 8 ( fresh install ), my bluetooth turned off....
I can't do anything to get it on anymore.Windows settings don't allow me to move the toggle button. If i press the same button, only the wireless goes off and i can turn it on again trough windows setting.
I uninstall all drivers and reinstall but nothing change.
I should be able to activate it trough the ePower Managament, but it seems the software does'nt work with windows 8 
when i go in c:/programmes/acer/epower.... every single *.exe won't open the soft .... I tried to reinstall it, nothing change, i don't have any ePowerTray in my toolbar...
When i go in device manager, I need to "show hidden devices" to be able to see a bluetooth option.
I also have a " other devices" where i've got a " bluetooth device" that seems not connected.
So what i might do to solve this stupid issue ? I saw someone saying on the internet i have to install windows 7 with ePower Management turn my bluetooth on and then reinstall windows 8. Really ? Is that the only way i've got ( ffs we are in 2013 .... ).
My computer is a acer aspire m5-481PTG ( i took the ePower soft from the support.acer website wich was in the windows 7 part for my pc )
Hope you will be able to help me. If there is no solution i guess i won't use windows 8 anymore, this OS is just killing me !
Thx
P.s. : Sorry for my english, I did my best
