Hi, I have an Acer Aspire 5720, and I never knew that it had bluetooth. I've pressed the bluetooth button on it several times before and I just got a message saying "No Bluetooth Device". Then, yesterday I pressed it and it said "Bluetooth Enabled" and a blue light came on. I was really suprised. Then later, when I turned on my laptop and pressed the button hoping I could do things with the BT, I got the "No Bluetooth Device" message again and I was dissapointed. So, I went on the Acer website and downloaded two different BT drivers for my laptop, and both setup.exe's gave me a "No bluetooth device detected. Please make sure that your bluetooth device is plugged in properly to continue the installation." What can I do to get my Bluetooth back?
