Press your Dell laptop’s “Power” button to turn it on and wait for it to finish booting up.
Slide your laptop’s hardware Bluetooth switch to the “On” position, if your computer has one.
Hold down the “Fn” key on your keyboard while pressing the “F2” key to turn on Bluetooth if your computer does not have a hardware switch.
Look for a blue icon with a stylized “B” in your system tray. If it appears, your Bluetooth radio is on.
