Compute Pack LED Guide

  • Updated

The compute pack on Magic Leap 2 can show anywhere from 1 - 5 LED dots. Different combinations of these dots and colors communicate different statuses about the device. While in normal operation, you LEDs will not be displayed on the compute pack.

 

Power Status LEDs

LED Meaning
Compute Pack Boot-up, five white LEDs light up from left-to-right in an arc

Compute Boot Up

Compute pack is waking up.
Compute Pack On, a single solid green LED

Compute On

Compute pack is on.
Compute Pack Standby,a single green LED fades in and out

Compute Standby

Controller is in a low power state ready to go into sleep mode.
Compute Pack Sleep, a single white LED fades in and out

Compute Sleep

Device is in sleep mode.
Compute Pack Shut Down, Five white LEDs fade out in an arc from right to left until no LEDs are on

Compute Shut down

Shut down starts with a long press of the power button.
Compute Pack Critical Battery Charging, a single LED light flashes red and white while the compute is charging at 5% charge

Compute Critical Battery Charging

The LED will pulse white and red when the compute pack is charging and the battery is 5% or less.
Compute Pack Critical Battery, a single solid red LED the compute pack has 5% or less charge

Compute Critical Battery Unplugged

Compute pack battery is critically low at 5% or less.

Compute Pack is Charging at 100%, 5 White LEDs blink

Compute Pack is Charging at between 76 and 99%, 4 White LEDs blink

Compute Pack is Charging at between 51 and 74%, 3 White LEDs blink

Compute Pack is Charging at between 26 and 50%, 2 White LEDs blink

Compute Pack is Charging at between 6 and 25%, 1 White LEDs blink

Compute Charging

  • Five LEDs show the battery level at 100% and charging.
  • Four LEDs show the battery level is between 76–99% and charging.
  • Three LEDs show the battery level is between 51–75% and charging.
  • Two LEDs show the battery level is between 26–50% and charging.
  • One LED shows the battery level is between 6–25% and charging.

Compute Pack Battery Check 26 - 50%, compute pack charge is between 26 and 50% - 2 white LEDs are shown

Compute Pack Battery Check 6 - 25%, compute pack charge is between 26 and 50% - 1 white LED is shown

Compute Battery Check

  • Five LEDs show the battery level is 100%.
  • Four LEDs show the battery level is between 76–99%.
  • Three LEDs show the battery level is between 51–75%.
  • Two LEDs show the battery level is between 26–50%.
  • One LED shows the battery level is between 6–25%.
