If your PC can connect to wireless devices, check that Bluetooth is turned on. Open PC settings by swiping in from the right-hand edge of the screen and tapping Search (or if you're using a mouse, pointing to the top-right corner of the screen, moving the mouse pointer down, then clicking Search). Enter Bluetooth in the search box, tap or click Settings, then tap or click Turn wireless communication on or off. Under Wireless devices, tap or click the Bluetooth control to turn it on.
