{% tab title="Powering On 🟢 " %}
There are two ways to power on your Looking Glass Go:

1. Connect one end of the cable to the USB-C port on the back of the display, and one end of the cable to a power outlet using the included power adapter.\
   This will activate **Standalone Mode (Solid White)**.
2. Alternatively, connect one end of the cable to the USB-C port on the back of the display, and one end of the cable to a computer.\
   When connected to a computer, your Go will effectively have **two** modes to operate on:\
   **Standalone Mode (Solid White)** or **Desktop Mode (Solid Blue)**.

Press the power button once to turn your Looking Glass Go on.
{% endtab %}

To power off your Looking Glass Go, hold down the power button until the light indicator is breathing white/blue.
{% endtab %}
{% endtabs %}

### Status LED Key

The Looking Glass Go has a status LED on the side of the device near the power button.

The status LED is helpful to determine what state the Looking Glass is in.
