Vacuum will not turn on at all; no lights or sounds

Safety first: Ensure the charger and battery are genuine Toshiba components.

• Step 1 – Charge battery: Place the battery on the charger for at least 3–4 hours. Confirm charger LED indicates charging.
• Step 2 – Test charger: If charger LED never lights, try another outlet or charger if available.
• Step 3 – Reseat battery: Remove and reinstall the battery, ensuring it clicks firmly into place.
• Step 4 – Check power button: Press and hold the power button for 3–5 seconds. Try different modes if available.

If the unit remains completely dead with a known‑good battery and charger, internal wiring or PCB failure is likely and requires professional service.
