{% stepper %}
{% step %}

#### Step 1:  Try to Power On the Device

1. Press and hold **Volume Up + Power** together for **30 seconds**.
2. Check if the device turns on
   * **Yes** – Your battery is working correctly and the device is operational.
   * **No** – Please continue to Step 2.
     {% endstep %}

{% step %}

#### Step 2: Connect the Device to a Charger

1. Plug the device into a charger.
2. Look for a **red LED indicator light**.
   * **If the red LED is blinking:**

     This means the battery is charging.

     * Wait until the red LED turns **off** (this usually takes about **15 minutes**).
     * Once the LED turns off, press the **Power** button to turn on the device.

   * If there is no LED light or no charging indication:

     * This indicates a possible battery fault.
     * Please contact the Helpdesk to raise the terminal for a replacement.

   * If the red LED continues blinking and does not turn off:
     * This indicates a battery fault.
     * Please contact the Helpdesk to raise the terminal for a replacement.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://helpcenter.verifone.com/t650-error-page/diagnostic/battery-fault.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
