Step-by-step
- Unscrew the hilt to access the Core.
- Remove the battery from the Core.
- Look at the contact plates where the battery sits. If they are pressed flat, gently bend them outward with a small screwdriver.
- Reinsert the battery and try to power on.
- If no response, charge the battery for another 30 minutes using an external charger (not the hilt).
- Try powering on again. If still no response, contact support with your order number.
