Step-by-step
- Power off the saber (if it responds to power button).
- Unscrew the hilt to access the Core.
- Remove the battery from the Core.
- Inspect the contact plates — gently bend out if pressed flat.
- Reinsert the battery. Charge for at least 1 hour.
- Try powering on. If still no response, contact support.
When to escalate
If the saber stops working during use, stops responding to the power button, or the blade flickers and dies — record a short video and email it to support@bjsaber.com with your order number. We will diagnose within 1-2 business days.
