Hello there, I have an Asus vivobook s551. It originally came with windows 8, but i had it removed and installed windows 7 instead because i didn't like windows 8. anyway, every driver worked flawlessly. the only problem is Bluetooth, it just wont work. there are no drivers for it for windows 7 on asus' website , but i installed the W8 version anyway. the installation worked but the software won't find any Bluetooth device. the laptop has Bluetooth built in and it used to work in windows 7. i even bought a Bluetooth dongle and still the same , it just wont find any device.i tried everything i could find online but still nothing. i tried the dongle on a friends laptop and it worked. i would appreciate any help getting Bluetooth to work . thanks a lot.
