 Once the firmware of your Alvik is up to date and before start playing with it, let's verify your battery works as it should by following these steps:
 
-1. Reset your Alvik by turning it OFF and disconnecting it from the PC.
+1. Make sure Alvik is OFF and disconnected it from the PC.
 2. Open the battery compartment and check that the clips are making contact with the battery. If they aren’t, remove the battery, adjust the clips to ensure proper alignment, and then reinsert the battery securely.
 3. Connect the Alvik to the PC keeping Alvik OFF.
 4. At this point some lights should turn ON in your Alvik:
 
 - **Green LED** (not confuse it with the PWR LED of the Nano ESP32) will turn ON in the ESP32

-  The battery may be faulty. To check it, turn Alvik ON; if an orange light near the QWIIC connector blinks every 10 seconds, contact our customer support for a replacement.
+  The battery may be faulty. To check it, turn Alvik ON; if an orange light near the QWIIC connector blinks every 10 seconds, contact our customer support for a replacement. A user-uploaded sketch will not run unless Alvik has a charged battery. If the battery is low, the sketch will halt its execution at the initialization phase.

 The battery is a rechargeable Li-ion 18650, it allows to run Alvik for 8+ hours non stop.
 
 When you connect your Alvik to the computer, the Nano ESP32 reports the status of the battery through the terminal of the Arduino Lab for MicroPython and with its RGB status LED. In order to see the state of the battery, you need to call the `Alvik.begin()` function in any program or directly at the command line area.
