Press your speaker's "Power" button to turn it on. The process for turning on a speaker will vary slightly from model to model, so consult your speaker's manual if you can't figure out how to turn it on.  If your speaker needs to be connected to a power source as well, make sure it's plugged in before continuing. You'll also want to make sure that your speaker is as close to your laptop as possible while pairing. Click the Windows logo in the bottom-left corner of the screen. It's in the lower-left side of the Start window. This option is near the top of the Settings page. It's a tab on the left side of the Devices page. Click the "Off" switch below the "Bluetooth" heading near the top of the page to turn on Bluetooth. If you see the word "On" to the right of this switch, Bluetooth is already enabled. This will prompt the speaker to begin searching for a Bluetooth connection to connect to (e.g., your computer). Again, this button's location and appearance will vary from speaker to speaker, so check your manual if you can't find the "Pair" button. This button is at the top of the page. It's the top option in the Add a Device window. You should see your speaker's name appear in the window after a moment. Clicking the speaker's name will select it. Your speaker's name will most likely be a combination of its brand and model number. It's in the lower-right side of the speaker's name card in the window. This will connect your speaker to your computer. You should now be able to play music and other audio from your computer through your speaker.
