From left to right:

- Hardware kill switch for camera and microphones (internal and external microphones will be cut off)
- White LED indicator for cam/mic kill switch, LED on=cam/mic on, LED off=killed
- Hardware kill switch for WiFi / Bluetooth
    - This severs power to the WiFi/BT M.2 slot and enables the #DISABLE signal on the M.2 slot
- White LED indicator for WiFi / Bluetooth, LED on=WiFi/BT active, LED off=killed
    - The LED can be repurposed using the Librem EC ACPI driver, see section "Hardware Specific Software" below
- Software controlable notification LED, red / gree / blue
- Power state LED, same states as the outside power state LED:
    - off - laptop is powered off
    - white - normal operation
    - green - charging
    - orange - battery state low (less than 20%)
    - steady on - laptop is powered up
    - glowing / fading on/off - laptop is in sleep mode

.. note::
   There is one case where the power state is ambiguous.
   When laptop is off but connected to the charger and charging, it shows a steady 'green' indicator until charging is finished, after which the LED turns off.
