Chassis

Overview

The Librem 5 is designed for longevity with lifetime software updates. Longevity also implies being able to repair a device outside of warranty. Purism plans to stock replacement components in the shop in case you need to replace your modem, camera, or even the main PCB.

Warning

Disassembling your Librem 5 may risk damaging it. Any damage from disassembly is not covered in the warranty. Contact Purism Support if your Librem 5 is under warranty before attempting this process.

  7. Remove PCB screws.

    Caution

    1. Be careful about screw lengths and keep the case screws and PCB screws separate. Using a long case screw in a PCB screw hole can damage the screen.

    2. The 3 screws at the top connect the antennas, so do not forget to reinstall them during reassembly.

  12. Lift the PCB out until you can see the Display and USB-C FPC cables.

    Caution

    When removing the PCB be careful of the spring clip against the frame. This spring clip is part of the GNSS antenna assembly. GPS reception will become practically nonexistent if this spring clip breaks off.

    Caution

    There is a cover over the proximity sensor that is easy to lose. Put it in a safe place. If the device is reassembled without this cover, the proximity sensor will trigger automatically, and would need to be disabled.

Reassembly

Follow this procedure in reverse order to reassemble the device. If the thermal paste looks satisfactory, begin by reattaching the PCB to the FPC cables and reattaching the proximity sensor cover.
