What Am I Using?

Bluetooth device won’t pair?

Check whether the accessory is discoverable, still connected to a different device or actually uses a USB receiver.

Does it appear in the list of nearby devices?

Charge the accessory and follow its manual to put it in pairing mode.

Check existing connections

An accessory may remember another host and reconnect to it before you can pair.

Temporarily disconnect it from the other device if practical. Try pairing again nearby.
If you remove an old pairing, make sure you can pair it again and have a spare input method if it is your mouse or keyboard.

Confirm the accessory is discoverable

Many devices are visible only while a pairing light flashes or for a short time.

Keep the accessory close and restart its pairing mode. Refresh the device list.
Try another compatible device. If neither sees it, check the manual for a switch, battery or pairing mode.

Confirm which connection the accessory uses

Some wireless accessories use a USB receiver and never appear in Bluetooth settings.

Check the exact model and whether a small receiver came with it.
Follow the model’s pairing guide. Use a working wired input device first if the accessory is your only keyboard or mouse.
