1. Use the official charger handheld first
Plug a genuine Nintendo charger straight into the bottom of the console — skip the dock. If it charges this way, your dock is the problem (very common: the USB-C board inside the dock fails).
2. If it still won't charge handheld
- Try a second official charger and cable. Third-party chargers can refuse to negotiate with the Switch.
- Inspect the USB-C port for lint, bent pins, or rocking — any side-to-side wobble of the plug means the port is loose and needs replacement.
3. Charges but won't power on
Hold Power for 15 seconds, then press once. If you get the boot logo, you're fine. If the orange light is on but the screen stays black, it's usually a screen or display-connector issue, not charging.
4. Battery drains overnight
If the Switch is older than ~3 years and dies fast even after a full charge, the battery has aged out — a battery replacement restores hours of play time.
