I/O ports

Left side from back to front:

• Kensington lock hole (strictly not a connector)

• HDMI

• USB3.1 type-A

• microSD card reader (push/pull spring loaded)

• USB3.1 type-C (data only + 5V power source)

Right side, from back to front:

• Power indicator LED (white / green / orange)

• Charger input, barrel connector, 4mm, center +19V DC, outside GND

• RJ45 gigabit Ethernet

• USB3.1 type-A

• USB3.1 type-C, full function with Display Port alt mode and Power Delivery sink

• 3.5mm headphone jack with microphone input

Note

A type-C charger must be able supply at least 19V. 60W or more recommended (it may work with less but then battery can be drained even with the charger connected).

Keyboard and touchpad

The keyboard features a dimmable white LED backlight. The touchpad is a I2C HID-compliant input device with one hardware push button (pushing the lower edge).

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.
