But the bluetooth still not work. can u help me? what's wrong woth my bluetooth?
If you have a Wi-Fi switch on your netbook, it controls your wireless devices (so Wi-Fi, Bluetooth, etc..) so if it's switched off, that would be your problem.
Otherwise, make sure you're actually connecting your device to it. Maybe try removing the device from "Devices" and re-add it like you would have initially.
