Problem

You want to connect the Basilisk V3 X HyperSpeed via Bluetooth, but the mouse doesn’t appear in the scan list, won’t complete pairing, or drops shortly after connecting on Windows or macOS.

Solution

Verify power and mode, put the mouse into Bluetooth pairing properly, then add it from your OS Bluetooth settings. If discovery fails, clear old pairings, reboot Bluetooth, and try again with a short, interference-free distance. For stubborn cases, reset the mouse’s pairing, update Bluetooth drivers or macOS, and test with another device to isolate whether the issue is the mouse or the computer.

Step-by-step instructions

A) Prepare the mouse

1. Insert a fresh AA battery and replace the cover.
2. Slide the underside switch to BT (center is Off, “2.4” is for the USB receiver).
3. Put the mouse into pairing mode: press and hold both side buttons + DPI Up + DPI Down for ~3 seconds until the status LED indicates pairing.

B) Windows 10/11

1. Open Settings > Bluetooth & devices and turn Bluetooth On.
2. Click Add device > Bluetooth.
3. Select Razer Basilisk V3 X HyperSpeed when it appears and complete pairing.
4. Test movement and clicks to confirm the connection.

C) macOS (Ventura/Sonoma/Sequoia)

1. Open System Settings > Bluetooth and turn Bluetooth On.
2. When Razer Basilisk V3 X HyperSpeed appears, click Connect.
3. Confirm the pointer moves smoothly.

D) If the mouse does not appear or pairing fails

1. Re-enter pairing mode on the mouse (side buttons + DPI Up + DPI Down for ~3 seconds).
2. Forget old entries: remove any existing “Razer Basilisk V3 X HyperSpeed” from the Bluetooth list.
3. Power cycle Bluetooth: turn Bluetooth Off, wait 10 seconds, then On.
4. Reboot the computer and try the scan again.
5. Move closer: keep mouse and computer within 20–30 cm, away from routers or metal surfaces.
6. Check battery: replace the AA if the LED is dim or the cursor stutters.
7. Windows only: in Device Manager > Bluetooth, right-click your adapter and choose Update driver; also disable any “Allow the computer to turn off this device to save power” option under Power Management for the Bluetooth adapter.
8. macOS only: ensure macOS is up to date, then remove the device again and retry.
9. Cross-test: try pairing the mouse to a phone, tablet, or another PC. If it works elsewhere, the issue is likely with the original computer’s Bluetooth stack or driver.
10. Reset sequence (last resort): turn the mouse Off, wait 10 seconds, turn to BT, re-enter pairing mode, and start the OS pairing process immediately.

Optional methods or tools

• Razer Synapse (Windows) to check battery level and confirm the mouse is recognized after pairing (for customization you’ll typically use the 2.4 GHz receiver, but Synapse can still confirm device health).
• USB 2.0 vs USB 3.0 ports: if you also use the HyperSpeed receiver sometimes, keep USB 3.0 devices/cables away from the Bluetooth antenna area, as they can contribute to 2.4 GHz noise that occasionally impacts BT stability.
• Firmware/OS updates: applying the latest mouse firmware (if available), Windows cumulative updates, Bluetooth stack/driver updates, or macOS updates can resolve intermittent pairing quirks.

Best practices or tips

• Keep the mouse and host within a short line-of-sight distance during first pairing; once bonded, you can increase range.
• Remove duplicate or stale Bluetooth entries before re-pairing; lingering records often block new bonds.
• If you frequently switch between two computers, consider Bluetooth on one and HyperSpeed receiver on the other; then just flip the hardware switch between BT and 2.4.
• Replace the AA battery proactively; low power can masquerade as “Bluetooth issues” (lag, failed connections, random drops).
• Avoid heavy 2.4 GHz congestion near the computer (Wi-Fi adapters, hubs, unshielded USB 3.x cables). A small change in receiver/cable placement or moving away from a router can dramatically improve stability.

Bluetooth is ideal for quick multi-device use and travel. For first-time success, always start with a known-good battery and a clean Bluetooth list, then enter pairing mode deliberately before scanning in the OS. If your system doesn’t see the mouse, power cycling Bluetooth and the computer clears most temporary stack issues. Keeping the devices close and away from metal or 2.4 GHz noise helps the initial bond complete quickly.

If pairing remains unreliable, focus on the computer side: update Bluetooth drivers (Windows) or apply the latest macOS update, and retest. Cross-testing with another device isolates whether the mouse or host is at fault. Once paired, set up app or game profiles the same way you would on the HyperSpeed receiver so the mouse feels consistent when you switch between Bluetooth and 2.4 GHz.
