Excuse me, where is the Bluetooth of Lenovo ThinkPad Edge E40 0578MDC and how to turn it on? Please answer, thank you!
If your computer has a built-in Bluetooth module, go to official website to download and install the driver, and see which one in the top row of the keyboard has the Bluetooth logo. Just press the FN+ key and you can turn it on. If not, you can only use an external Bluetooth receiver, which is very cheap.
